STANDARD (SAUDI CAFE) FOR INCOMING LIGHT DUTY 
VEHICLES ( 2024 - 2028 ) 
 
INTRODUCTION  
 
This standard is a continuation of SASO 2864/201 9 (Saudi Arabia Corporate Average Fuel 
Economy Standard (Saudi CAFE) for incoming light duty vehicles ( 2021 – 2023).  
 
The objective of this standard is to set the fuel economy performance requirements for all light -
duty vehicles (i.e. passenger cars and li ght trucks) incoming to the Kingdom of Saudi Arabia, 
which includes vehicles imported or vehicles locally produced for the intent of sale in the 
Kingdom of Saudi Arabia. This standard is part of Saudi Arabia’s integrated approach to 
improve energy efficien cy in the transportation sector.  
 
The transportation sector is the second largest consumer of energy in the Kingdom of Saudi 
Arabia, and its consumption is projected  to significantly grow in the foreseen future. In addition, 
the number of incoming light -duty vehicles over the next years is expected to surpass the current 
on-the-road stock. As such, addressing the energy efficiency of this segment of vehicles is of 
utmost importance to the Kingdom of Saudi Arabia. This dictated the establishment of a fuel 
economy standard to achieve the objective.  
 
This fuel economy standard will cover both new incoming vehicles and used import vehicles, 
ensure technology neutrality, eq uitable competitiveness and sustainable progressive targets 
taking into account the diversity of consumer demand and automobile manufacturers supply.  
 
The fuel economy targets for new incoming light -duty vehicles were defined based on the 
corporate average  concept and according to the utility of the vehicle in order to maintain the 
diversity of the market and its ability to cater for different consumer needs. The utility of the 
vehicle is described by two aspects: motor vehicle class and a representative ve hicle attribute. 
As such, two different sets of targets were established for passenger cars and light trucks given 
the shear difference in the consumer utility for these two motor vehicle classes. In addition, the 
fuel economy targets for each vehicle clas s were defined according to the vehicle footprint 
(average track width multiplied by the wheelbase). Footprint was selected, as opposed to 
weight, to allow automotive manufacturers to effectively utilize light -weighting technologies.  
 
The aim of this stand ard is to incentivize the automotive manufacturers to introduce the latest 
energy efficiency technologies to the Kingdom of Saudi Arabia, and reduce the supply of 
vehicles equipped with inferior technologies to the market.  
 
For new incoming vehicles, autom otive manufacturers will be allowed to average the fuel 
economy over their whole incoming fleet rather than having to meet the targets for each vehicle 
individually.  SASO  STANDARD                                   SASO 2864 /0000  
 
 4 Automotive manufacturers would, therefore, be required to ensure that the average fuel 
economy for all the new incoming vehicles (i.e. imported or locally produced for the intent of 
sale in the Kingdom of Saudi Arabia) does not fall below the average fuel economy targets for 
those vehicles. This requirement shall commence on January 1, 20 24 and shall be enforced on 
a 12-months cycle.  
 
The standard allows for multiple flexibilities for allowing automotive manufacturers to meet 
their fuel economy targets. Automotive manufacturers will be able to accumulate fuel economy 
credits that would be genera ted from exceeding the fuel economy targets for a given 
enforcement cycle. The validity of the fuel economy credits shall be limited to five (5) 
enforcement cycles. In addition, automotive manufacturers will be able to carry -back deficits 
that would be gen erated in cases of non -compliance.  Automotive manufacturers could also 
transfer generated and accumulated credits between the two motor vehicle classes in order to 
achieve compliance. SASO has established a Data sharing program in order to enhance its 
current vehicle database. Finally, automotive manufacturers participating in the Data Sharing 
Program would also be eligible to receive additional flexibility mechanisms.  
 
The fuel economy targets for used import vehicles are defined as absolute minimum fuel 
economy per vehicle independent of its attribute. Two separate targets were set for each motor 
vehicle class (i.e. passenger cars and light trucks).  
 
The Kingdom of Saudi Arabia’s sole interest of setting the fuel economy standard is to curtail 
the ineffici ent domestic demand growth for transportation fuels. Therefore, an enforcement 
mechanism that would ensure all imported and locally produced vehicles meet the requirements 
is set forth by the fuel economy standard.

4- DETAILED DESCRIPTION OF THE STANDARD FOR  NEW INCOMING 
VEHICLES  
 
The fuel economy standard for new incomi ng vehicles in the Kingdom of Saudi Arabia is 
based on the corporate average concept. The technical details of the standard are explained 
below:  
 
4.1 The enforcement date  
The standard shall be effective as of January 1, 20 24 and shall last until December 31, 202 8.  
 
 
 
                                                   
1 If the fourth decimal point in the footprint value of the vehicle is 5 or higher, the automotive manufacturer should 
round -up. For example, a vehicle that has a footprint of 4.3266 m2 shall be reported as 4.327 m2. If fourth decimal 
point in the footprint  value of the vehicle is 4 or lower, the automotive manufacturer should round -down. For 
example, a vehicle that has a footprint of 4.3264 m2 shall be reported as 4.326 m2. SASO  STANDARD                                   SASO 2864 /0000  
 
 10 4.2 The attribute -based target curves  
An attribute -based target curve is defined as a curve linking the fuel economy target of the 
vehicle to one of its attributes (e.g. weight, engine displacement or footprint) .  
 
The target curves of the here -mentioned fuel economy standard for new incoming vehicles are 
defined as a function of the footprint of the vehicle.  
 
While all the aforementioned attributes were considered, and although the weight is the most 
adopted ve hicle attribute globally, the attribute of the corporate average standard for new 
incoming vehicles in the Kingdom of Saudi Arabia is set as the footprint. Footprint was deemed 
the most effective attribute due to weight and engine downsizing incentives. Re ducing weight 
and engine displacement are two effective means to improve the vehicle fuel economy. 
However, automotive manufacturers are less incentivized to reduce the attribute value (i.e. 
weight or engine displacement) under the same attribute -based sta ndard. For example, light 
weighting would require the automotive manufacturer to meet a stricter target, as lighter 
vehicles need to achieve higher fuel economy targets. However, under a footprint -based 
standard the target fuel economy would not change whi le improving the fuel economy. As such, 
the manufacturer can fully benefit from its light -weighting technology investment.  
 
Each motor vehicle class (i.e. passenger cars and light trucks) shall have its own target curve.  
 
All new incoming light duty vehic les shall be classified as either passenger cars or light trucks.  
 
Each new incoming vehicle shall be accounted under either the passenger cars target curve or 
the light trucks target curve.  
 
The footprint -based target curves shall be increased on an annu al basis to ensure progressive 
energy efficiency improvement and achieve a higher market average fuel economy.  
 
4.3 The enforcement cycles  
The first year curves (20 24 year curves) shall be adopted between January 1, 20 24 and 
December 31, 20 24 (enforcement cycle #1).  
 
The second year curves (20 25 year curves) shall be adopted between January 1, 20 25 and 
December 31, 20 25 (enforcement cycle #2).  
 
The third year curves (20 26 year curves) shall be adopted between January 1, 20 26 and 
December 31, 20 26 (enforcement cycle #3).  
 
The fourth  year curves (20 27 year curves) shall be adopted between January 1, 20 27 and 
December 31, 20 27 (enforcement cycle # 4).

The automotive manufacturer will be allowed to use the flexibilities detailed below:  
 
4.5.2.3.3.1  Credit carry forward  
In the case of over-compliance in an enforcement cycle “i”, the automotive manufacturer will 
be allowed to accumulate credits.  
 
These credits can be used to achieve compliance in coming enforcement cycles by adding them 
to the balance of the credit/deficit systems of the  respective motor vehicle class.  
 
Credits generated shall be available to the automotive manufacturer for use in any of the five 
enforcement cycles  after the enforcement cycle in which they were generated.  
 
No limit shall be applied to the amount of accum ulated credits that are carried forward within 
the timeframe specified above (five enforcement cycles): (i+1), (i+2), (i+3), (i+4), (i+5).  
 
4.5.2.3.3.2  Credit carry backwards  
Automotive manufacturers will be allowed to carry back deficits generated in any given 
enfor cement cycle, for one subsequent enforcement cycle.  
 
In case of non -compliance in enforcement cycle “i”, the automotive manufacturer will then be 
allowed a period of one enforcement cycle to offset the accumulated deficit  
  
In case not enough credits are accumulated in the enforcement cycle subsequent to enforcement 
cycle “i” to offset all deficits generated (i.e. the automotive manufacturer still carries deficits in 
enforcement cycle “i+2”), the enforcement mechanism detailed in section 6.1.3.3 will be 
applied on the non -compliant automotive manufacturer.  
  
An automotive manufacturer may not carry both credits and deficits simultaneously at any 
given enforcement cycle.

 20 4.5.2.3.3.3  Credit transfer across motor vehicle classes  
The automotive manufacturer will be allowed to tra nsfer its credits  in the same enforcement 
cycle from one motor vehicle class to another (i.e. from passenger cars to light trucks and vice -
versa).  
 
Credits carried forward can also be transferred from one motor vehicle class to the other with in 
the maximum allowed timeframe of five enforcement cycles.  
 
No limit shall be applied to the transfer of banked (generated and carried forward) credits 
between the two motor vehicle classes.  
 
Credits shall be transferred at the ratio of 10 to 8 between t he two vehicle motor vehicle classes 
i.e. each 10 credits in the passenger cars motor vehicle class will be accounted as 8 credits if 
transferred to the light trucks motor vehicle class.  
 
4.5.2.3.4 Additional flexibility mechanisms  
Automotive manufacturers  who enroll in the Data Sharing Program shall be eligible to receive 
additional flexibility mechanisms detailed in Appendix – I below.

5- DETAILED DESCRIPTION OF THE STANDARD FOR  U SED IMPORT 
VEHICLES  
 
The fuel economy standard for incoming used import vehicles in the Kingdom of Saudi Arabia 
is based  on the minimum energy performance concept i.e.  
 
a. A minimum allowed fuel economy is defined in advance.  
b. If the actual fuel economy of the vehicle is strictly less than the minimum allowed fuel 
economy, the vehicle will be banned from entering the Kingdom o f Saudi Arabia.  
 
The technical details of the standard are explained below:  
 
5.1 The enforcement date  
The standard shall be effective as of January 1, 2024 and shall last until December 31, 2028. 
 
5.2 The minimum allowed fuel economy  
Each motor vehicle cl ass (i.e. passenger cars and light trucks) will have a different minimum 
allowed fuel economy,  
 
The minimum allowed fuel economy should be adopted as of January 1, 20 24 and is defined 
at:  
 
a. 10.3 km / liter for passenger cars tested as per the US EPA driving cycle.  
b. 9.0 km / liter for light trucks tested as per the US EPA driving cycle.  
Shall SASO decide to update the minimum allowed fuel economy requirements on used 
imports, an amendment will be shared with all stakeholders, including automotive 
manufa cturers and importers.  
A minimum of six months grace period shall be provided prior to the enforcement of the 
amended minimum allowed fuel economy requirements.  
 
5.3 Determination of the actual fuel economy of the used import vehicle  
Vehicles shall be granted an actual fuel economy value based on “SASO fuel economy 
database”. A copy of the database will be available with the Saudi Customs and SEEC.  
 
If the vehicle is not available on the “SASO fuel economy database ”, the importer should 
provide the mode l fuel economy based on the results of the tests conducted in a SASO or 
International Laboratory Accreditation Cooperation (ILAC) accredited laboratory.

 26 6.1.3 Standard enforcement (at end of ongoing enforcement cycle)  
 
6.1.3.1  At the end of the o ngoing enforcement cycle, SEEC will assess the compliance of each 
automotive manufacturer in accordance with section 4.5.2.3 of this standard and using 
the Saudi Arabia fuel economy software, where:  
 
6.1.3.1.1  Automotive manufacturers complying with the standard may  resume their operations 
in the Kingdom of Saudi Arabia normally.  
 
6.1.3.1.2  Automotive manufacturers not complying with the standard shall submit a supply 
plan that ensures compliance with the standard i.e. the subject automotive 
manufacturer should submit a plan t hat generates, in the next enforcement cycle, 
enough credits to offset the deficit generated from the past enforcement cycle, as 
mentioned in section 6.1.1.7  
 
6.1.3.2  Automotive manufacturers will be informed of their fuel economy performance no 
later than six mon ths after the conclusion of the ongoing enforcement cycle.  
 
6.1.3.3  Automotive manufacturers which are not compliant with the standard (compliance 
shall be determined as described in section 4.5.2.3 of this standard) shall be required 
to achieve the target on each  model rather than on a fleet average starting with the next 
upcoming enforcement cycle and for at least one enforcement cycle, where the 
minimum allowed fuel economy for each model will be determined using the target 
curves of the next upcoming enforcemen t cycle as detailed in section 4.4 (i.e. within 
each motor vehicle class, each footprint is assigned a minimum allowed fuel economy 
target).  
 
6.1.3.4  This requirement shall continue until the automotive manufacturer accumulated 
enough credits to offset the deficits due.  
 
6.1.4 Petitions and dispute resolution  
 
6.1.4.1  Automotive manufacturers have the right to petition the compliance results shared by 
MC. Petitions shall be submitted to the Fuel Economy Committee.  
 
6.1.4.2  The automotive manufacturer will be required to submit a comprehensive report 
stating the purpose of the petition and all necessary supporting data and reports.  
 
6.1.4.3  Disputes that are not resolved through reconciliation may be directed, either by the 
Fuel Economy Committee or by the automotive manufacturer,  to the judicial 
authorities of the Kingdom of Saudi Arabia.  
 SASO  STANDARD                                   SASO 2864 /0000  
 
 27 6.1.4.4  For an automotive manufacturer filing a petition, the requirements of sections 6.1.1, 
6.1.2 and 6.1.3 shall remain effective until a decision emerges from the Fuel Economy 
Committee or the judi cial authorities.  
 
6.2 Implementation mechanism of the standard for used import vehicles  
 
6.2.1  Pre-border (before commencement of upcoming enforcement cycle)  
 
6.2.1.1  The importer shall be responsible to provide the actual fuel economy of the used 
import vehicle (as described in section 5.3).  
 
6.2.1.2  For a used import vehicle to be allowed to enter the Kingdom of Saudi Arabia, the 
actual fuel economy shall be equal or greater than the minimum allowed fuel economy 
(as described in section 5.2)  
 
6.2.2 At the border  (during ongoing enforcement cycle)  
 
6.2.2.1  Saudi Arabia Customs shall compare the reported actual fuel economy of each used 
import vehicle (as determined in accordance with section 5.3) with the minimum 
allowed fuel economy (as determined in accordance with sect ion 5.2).  
 
6.2.2.1.1  If the actual fuel economy of the used import vehicle is greater than or equal to the 
minimum allowed fuel economy, then the vehicle shall be granted custom clearance 
(assuming that all other requirements are satisfied i.e. safety requirements, emissions 
requirements, etc.)  
 
6.2.2.1.2  If the actual fuel economy of the used vehicle is strictly less than the minimum 
allowed fuel economy of the same vehicle, then the vehicle shall not be granted 
custom clearance independently of whether it satisfies other req uirements or not.  
 
6.2.2.2  MC, or whoever  it delegates, reserves the right to sample any vehicle and send it for a 
local laboratory of its choice for fuel economy testing to ensure compliance with 
declared fuel economy. The importer shall be responsible for vehicle delivery to the 
testing facilit y and the expenses of the test.  
 
7- ANNUAL REPORTS  
 
7.1 SASO shall issue and publicize an annual report post the conclusion of the enforcement 
cycle illustrating for each Motor Vehicle Class (i.e. PC and LT) per manufacturer  
1. The actual fuel economy performance  
2. The target fuel economy performance  
3. The credits obtained during the same enforcement cycle  
4. The accrued credit balance

Additional flexibility mechanisms  
 
In addition to the flexibility mechanisms described in section 4.5.2.3.3, the automotive 
manufacturers participating in the Data Sharing Program as detailed in section 4.5.2.3.4 will be 
eligible to receive the additional flexibilities detailed below:  
 
 Extended deficit credit carry backwards  
 
Automotive manufacturers, eligible to receive the additional flexibilities, will be allowed to 
carry back deficits generated in any given enforcement cycle, for three subsequent enforcement 
cycles.  
 
In case of non -compliance in enforcement cycle “i”, the automotive manufacturer will then be 
allowed a period of three enforcement cycles to offset the accumulated deficit.  
  
In case not enough credits are accumulated in the three enforcement cycles subsequent to 
enforcement cycle “i” to offset all deficits generated (i.e. the automotive manufacturer still 
carries deficits in enforcement cycle “i+4”), the enforcement mechani sm detailed in section 
6.1.3.3 will be applied on the non -compliant automotive manufacturer.  
 
An automotive manufacturer may not carry both credits and deficits simultaneously at any 
given enforcement cycle.  
 
 Off-cycle technology credits  
 
Starting on the first enforcement cycle of the standard (Jan 1, 20 24 – Dec 31, 20 24) onwards, 
automotive manufacturers, eligible to receive the additional flexibilities, will be allowed to 
generate credits, for the use, in their fleet of passenger cars or light trucks, of technologies 
designed to reduce real -world fuel consumption which cannot be completely measured using 
the testing approach specified in Section 4.5.2.1 of this standard. These credits are referred to 
as “off -cycle technology credits”.  
 
a- Automotive manufact urers may generate off -cycle technology CO 2 credits (grams 
CO2/mile) for certain technologies in agreement with U.S Code of Federal Regulations 
Title 40 CFR 86.1869 – 12 (b)(1)  
 
b- For technologies not covered in provision a above and verifiable by the 5 -cycle testing 
methodology, automotive manufacturers may generate off -cycle technology CO2 
credits (grams CO2/mile) in agreement with U.S Code of Federal Regulations Title 40 
CFR 86.1869 – 12 (c)  
 
c- For technologies not covered in provision a above and not verifiable by the 5 -cycle 
testing methodology, automotive manufacturers may generate off -cycle technology SASO  STANDARD                                   SASO 2864 /0000  
 
 33 CO2 credits (grams CO2/mile) in agreement with U.S Code of Federal Regulations Title 
40 CFR 86.1869 – 12 (d)(1)  
 
The calculated off -cycle technology CO2 credits in grams CO2/mile for each technology shall 
be converted to liters/kilometer in accordance with the following equation:  
 
Off−cycle  technology  fuel consumption  improvement  per technology  (l
km)
= Off−cycle  technology  CO2  credits  per technology  (gCo2
mi)
1.609344  × CO2  content  factor  (gCo2
l) 
 
Where CO2 content factor is determined as per the below table:  
 
Fuel type  CO2 content factor (grams CO2/liter)  
Petrol  2337  
Diesel  2684  
 
The actual fuel economy of all vehicles equipped with the off -cycle technologies will be directly 
adjusted to incorporate the impact of the installed technologies. The off -cycle efficiency credits 
shall be capped at 0.00266 l/km  per year on a combined pass enger car and light truck fleet 
average. The cap would not apply on a vehicle model basis, allowing automotive manufacturers 
the flexibility to focus off -cycle technologies on certain vehicle models and generate 
improvements for that vehicle model in exces s of 0.00266 l/km.  
 
Manufacturers seeking off -cycle credits must submit an application for off -cycle credits 
determined under provisions b and c of this section. As per U.S Code of Federal Regulations 
Title 40 CFR 86.1869 – 12 (e)(2), the application must contain the following:  
 
1- A detailed description of the off -cycle technology and how it functions to reduce CO2 
emissions under conditions not represented on the FTP and HFET.  
2- A list of the vehicle model(s) which will be equipped with the technology.  
3- A de tailed description of the test vehicles selected and an engineering analysis that 
supports the selection of those vehicles for testing.  
4- All testing and/or simulation data required under provision b or c of this section, as 
applicable, plus any other data the manufacturer has considered in the analysis.  
5- For credits under provision c of this section, a complete description of the methodology 
used to estimate the off -cycle benefit of the technology and all supporting data, 
including vehicle testing and in -use activity data.  
6- An estimate of the off -cycle ben efit by vehicle model and the fleet -wide benefit based 
on projected sales of vehicle models equipped with the technology.  
7- An engineering analysis and/or component durability testing data or whole vehicle 
testing data demonstrating the in -use durability of  the off -cycle technology components.  
 
SASO, or whomever it delegates, will review the automotive manufacturer request and 
approve/decline accordingly.

 34  Air-conditioning efficiency credits  
 
Starting on the first enforcement cycle of the standard (Jan 1, 20 24 – Dec 31, 20 24) onwards, 
automotive manufacturers, eligible to receive the additional flexibilities, will be allowed to 
generate credits for the use, in their fleet of passenger cars or light trucks, of air conditioning 
systems that incorporate technologies designed to reduce air -conditioning -related fuel 
consumption by improving the air conditioning system efficiency of those fleets. The menu of 
technologies which an automotive manufacturer may utilize to ge nerate air-conditioning 
efficiency credits along with the maximum credit limit for each technology is illustrated in the 
table below:

 35 In order to receive the full amount of Air -Conditioning efficiency credits, the difference 
between the new and baseline results should be  equal to or greater than the sum of the menu -
based credits for technologies present on the new vehicle; where:  
 
 
 In cases where the difference between the new and baseline results are greater than 0 
but less than the sum of the menu -based credits, manufacturers can:  
 
- Submit an engineering analysis that justifies the generation of the full amount of 
A/C efficiency credits, or  
- Receive partial credits (proportionally to the ratio of the difference of the AC17 
test results and the sum of the new technol ogy menu credits)  
 
 In cases where no baseline comparison test results is available (e.g. brand -new platform 
has been created), manufacturers will be required to submit an engineering analysis that 
justifies the generation of the full amount of Air-Conditioning efficiency credits  
 
 
The actual fuel economy of all vehicles equipped with the Air -Conditioning efficiency will be 
directly adjusted to incorporate the impact of the installed technologies.  
 
The air -conditioning efficiency credits shall be  capped at 0.0026 l/km and 0.0037 l/km for 
passenger cars and light trucks accordingly  
 
SASO, or whomever it delegates, will review the automotive manufacturer request and 
approve/decline accordingly.  
 
 Exemption of emergency and law -enforcement vehicles  
 
Automotive manufacturers, eligible to receive the additional flexibilities, may apply for an 
exemption for vehicles sold for emergency and law -enforcement purposes from the here -
mentioned corporate average standard.  
 
The follow ing are general guideline s for emergency and law -enforcement vehicles:  
 
(i) Emergency vehicles refer mostly to ambulances and civil defense vehicles  
(ii) Law enforcement vehicles refer mostly to vehicles used by law enforcement agencies 
for the purpose of enforcing regulations in the country;  e.g. Police, Traffic Police, 
Highway Patrol, Military, etc. Law enforcement vehicles exemption does not pertain to 
vehicles used by government agencies for non -law enforcement purposes  
 
 Automotive manufacturers wishing to benefit from this flexibility sh all submit a copy of the 
official contract with the specific government agency in the Kingdom listing all the vehicles 
along with their technical specifications as illustrated in sections 6.1.1.2.1 -6, 6.1.1.2.11 and 
6.1.1.2.15 -17  
 
SASO, or whomever it delegates, will review the automotive manufacturer application and 
approve/decline accordingly.  
 SASO  STANDARD                                   SASO 2864 /0000  
 
 36  Air conditioning and off -cycle technologies submission deadline  
 
Automotive manufacturers must update the supply plans to include the air-conditioning and 
off-cycle credit requests prior to the conclusion of the fourth  month post the enforcement 
cycle (i.e . before May 1st of the subsequent enforcement cycle).  
 Credit transfer between automotive manufacturers  
 
Automotive manufacturers would be allowed to transfer credits to other automotive 
manufacturers provided that both parties are eligible to receive the additional flexibilities.  
 
An automotive manufacturer can only start transferring credits to other manuf acturers after 
offsetting any deficits it may have.  
 
An automotive manufacturer cannot transfer more credits than available in their Credit Balance.  
 
An automotive manufacturer can only receive credits in a  certain  motor vehicle class with 
deficit i.e. no  credits available in this motor vehicle class  
 
Credits previously transferred between two motor vehicle classes cannot be transferred from 
one manufacturer to another.  
 
In order to ensure that the fuel savings are preserved, an adjustment factor needs to be applied 
to the credits when transferred from one manufacturer to another.  
  
The transfer adjustment factor is determined as per the below formula:  
 
VKT  e,v class  e,enforcement  cycle  "i" * CAFE ACTUAL u, v class u, enforcement cycle "j" ∗ CAFE  TARGET  u,v class  u,enforcement  cycle   "j"  
VKT  u,v class  u,enforcement  cycle  "j" * CAFE ACTUAL e, v class e, enforcement cycle "i" ∗ CAFE  TARGET  e,v class  e,enforcement  cycle  "i"  
 
Where,  
 
VKT e, v class e, enforcement cycle “i”  is the lifetime vehicle kilometers traveled of the 
originating automotive manufacturer (earner) in the specific vehicle class and during 
enforcement cycle “i” in which the credit was earned  
 
CAFE ACTUAL u, v class u, enforcement cycle “j”  is the actual fue l economy of the 
receiving automotive manufacturer (user) in the specific vehicle class and during enforcement 
cycle “j” in which the credit is used for compliance  
 
CAFE TARGET u, v class u, enforcement cycle “j”  is the target fuel economy of the 
receiving  automotive manufacturer (user) in the specific vehicle class and during enforcement 
cycle “j” in which the credit is used for compliance  
 
VKT u, v class u, enforcement cycle “j”  is the lifetime vehicle kilometers traveled of the 
receiving automotive manuf acturer (user)  in the specific vehicle class and during enforcement 
cycle “j” in which the credit is used for compliance  
 
CAFE ACTUAL e, v class e, enforcement cycle “i”  is the actual fuel economy of the 
originating automotive manufacturer (earner) in the specific vehicle class and during 
enforcement cycle “i” in which the credit was earned  SASO  STANDARD                                   SASO 2864 /0000  
 
 37  
CAFE TARGET e, v class e, enforcement cycle “i ” is the target fuel economy of the 
originating automotive manufacturer (earner) in the specific vehicle class and during 
enforcement cycle “i” in which the credit was earned  
 
For the purpose of this standard, the lifetime vehicle kilometers traveled for the passenger cars 
vehicle class and for the light trucks vehicle class during any enforcement cycle will be 
considered equ al. 
 
 Performance Premium  
If an automotive manufacturer’s average fuel economy ( km/l) for a given vehicle category 
(passenger car, light truck) falls below the  standard’s target for a given enforcement cycle, and 
the automotive manufacturer cannot offset all deficits by using the credits earned or acquired, 
then the automotive manufactur er will be allowed to obtain credits directly from the 
government to offset the deficits  only. This flexibility is only applicable for automotive 
manufacturers that are not compliant with the standard (compliance shall be determined as 
described in section  4.5.2.3 of this standard) . 
 
The amount of deficit  is multiplied by the  “performance premium” rate . The basic equation for 
calculating a n automotive manufacturer’s “performance premium”  amount,  is as follows:  
(amount  of deficit ,in tenths  of 𝑘𝑚/𝑙)×(performance  premium  rate ,in 𝑆𝐴𝑅  per 0.1 𝑘𝑚/𝑙 per vehicle )
×(# of vehicles  in manufacturer ’s noncompliant  fleet ) 
 
SASO, or who mever it delegates, reserves the right to periodically revise and update the 
“performance premium ” rate in  alignment with the kingdom’s objectives.  Automotive 
manufacturers will be informed with the new “performance premium” rate once it is officially 
announced.  
 
 Derogation from standard requirements for independent small -volume 
manufacturers  
Automotive manufacturers, eligible to receive the additional flexibilities, can apply for a 
derogation from standard requirements, provided that their global sales do not exceed 10,000 
vehicles per year. This rule applies to independent automotive manufact urers (that are not 
affiliated with other automotive manufacturers) or automotive manufacturers affiliated to a 
Parent Group, provided they are able to demonstrate operational independence from their 
respective Parent Group.  
 
For an automotive manufacturer  to demonstrate operational independence from their Parent 
Group, they need to operate their own research, design, production, and manufacturing facilities 
independently from the Parent Group.   
 
For any eligible automotive manufacturer to be granted the d erogation from standard 
requirements during a specific enforcement cycle, they need to submit a detailed improvement 
plan to SASO.  
The detailed improvement plan should include:  
 
(i) A supply plan in accordance with section 6.1.1.2  
(ii) Projected level of fuel econo my improvements for each model for the next three 
years  SASO  STANDARD                                   SASO 2864 /0000  
 
 38 SASO, or whomever it delegates, will review the automotive manufacturer application and 
approve/decline accordingly.
