The F160 is a 60° V6 gasoline engine that displaces 2979 cc .
 It utilizes a turbocharger for each cylinder bank, twin intercoolers and direct injection.
 The engine is designed by Ferrari (loosely based on Pentastar engine block) and assembled by Ferrari; specifically, the engine blocks are cast and machined to Ferrari's approved specifications respectively in Chrysler's Kokomo, Indiana and Trenton Engine Plant, then shipped to Modena, Italy for assembly by Ferrari.
 This engine shares bore and combustion chamber design, the same valves control technology (i.e. roller finger followers and four cam phasers), the same twin turbocharging approach and direct injection-ignition system with Ferrari F154 engine.
 The engine auxiliaries are identical (alternator, starter motor and power steering pump) or very similar (variable displacement oil pump).
 The difference of F160 from F154: F160 engine block is made by high pressure die cast (HPDC) process which is extremely suitable for high volume production.
 However, it is open deck type and can't endure to high specific power in HP/liter.
 F160 doesn't have an overboost function and is not used in Ferrari cars either (both F136 and F154 engines are used in Ferrari cars as well).
 Ferrari was responsible for design and bench testing of this engine.
Power Stroke is a line of diesel engines found in Ford diesel trucks, Ford Excursion SUVs, Ford Econoline vans, Ford LCF commercial vehicles and the Brazilian Ford Ranger.
 The V8 engines were produced by Navistar International Corp. until 2010 when Ford decided to build their diesel engine completely in-house.
 The Power Stroke engines compete primarily in the United States full-size pickup truck market with the Duramax V8 from General Motors/Isuzu and the B Series straight-six from Cummins.
The Lexus GX (Japanese: レクサス・GX, "Rekusasu GX") is a luxury mid-size sport utility vehicle (SUV) sold in North American and Eurasian markets by Lexus.
 The name GX stands for Grand Crossover.
 Lexus introduced the first generation, known as the GX 470 in 2002, and subsequently became the third SUV to enter the Lexus lineup.
 A five-speed automatic was always standard, as was a full-time four-wheel-drive system with low-range gearing.
 The 4.7-liter V8 engine in the GX 470 was the same as used on the larger LX 470.
 The firm next introduced the second generation model in 2009, badged GX 460 to reflect the switch to a 4.6-liter V8 engine.
 Lexus later released a lower displacement GX 400 in 2012 for the Chinese market, with a 4.0-liter V6 engine.
The Medium Diesel Engine (MDE) is a four-cylinder diesel engine developed by Adam Opel AG and branded "1.6 CDTI Ecotec" in most markets.
 Opel also adds the marketing term "Whisper Diesel" in some markets, claiming relatively low levels of noise, vibration, and harshness.
 Production commenced in late 2013 at Szentgotthárd, Hungary.
 The MDE is Opel's first all-aluminum diesel engine and offers a power density of 85 HP per liter (136 PS) in its most powerful version.
 Maximum power and torque have been increased versus the previous-generation 1.7-liter engine, while fuel consumption has been reduced by up to 10 percent compared with a 2.0-liter CDTI engine of similar power output.
 This new 1.6 CDTI engine will replace the current 1.7-liter and lower-powered 2.0-liter diesel engines in a wide range of Opel models, with more- and less-powerful versions to come.
 The most powerful version of this engine, delivering 136 PS at 3,500–4,000 rpm and 320 Nm at 2,000 rpm, was first introduced in the 2013 Opel Zafira Tourer, and later in the 2014 Opel Astra J and restyled 2014 Opel Meriva B.
 In 2014, versions were released with power outputs of 110 PS and 95 PS.
At first the model had a new petrol engine with 1395 cc and 29 kW (39 hp) at 3800 rpm to 1400 Fiat, and had a manual 4-speed transmission.
 A 1.5 ton truck was newly developed, which was offered from 1951 in a flatbed and chassis for special bodies.
 It was powered by the engine of the prior year featured Fiat 1400s.
 The engine was already in the car Fiat 1400 was just sufficient, and with the 3.1 tons it had real trouble.
 Once in motion, the Fiat 615 was indeed 80 km/hr fast, but with forced driving it had poor fuel efficiency.
 There was a reason that the 1100 Fiat ELR far built until 1954.
 The somewhat weaker beast of burden was, with its 1.1 liter and 28/30 PS (at 4400 rpm) a little lame, but it had fully loaded a ton to move less weight, so was more economical.
 It therefore retained its loyal following who forgave its manageable liveliness out of habit, especially as it came with start-up to a peak of over 90 km/hr and thus was significantly faster than the Fiat 615 with its maximum of 78 km/hr.
 With high pressure, therefore a suitable diesel engine was developed by Fiat: a swirl chamber engine (Ricardo System) based on the 1.9 liter engine for the "big" Fiat in 1900 and the new SUV Fiat Campagnola.
 (This engine was a hubvergrößerte variant of the 1400 engine.)
 The new diesel engine (type 305) was later also available in either sedan 1400 from 1952 in addition to the Fiat 615 N (N = Nafta = Diesel) and one year in Fiat Campagnola and Fiat.
 Although the experiment of the Fiat 615 built 1.9 L gasoline engine proved to be stronger and with faster drive spurt, confined themselves to the diesel, the Type 615 N. Only Steyr in Austria until 1958 offered the Fiat 615 as gasoline, as Steyr 260 with its own 50 hp 2 L gasoline engine from the car Steyr 2000.
 The Fiat 615 N was a very modern vehicle that in Italy, initially had no competition.
 The export ran well at the beginning, missing, or half-hearted development left the Fiat 615 N (and especially its successor) over the years become increasingly rare even in Italy.
 In Zastava in Yugoslavia, the Fiat 615 was built with a petrol engine under license.
 However, not as the beginning of the Fiat, with the 1.4 L 4-cylinder engine, but with the much stronger torque 1.9 liter engine (type 105) with 47 hp at 3500 RPM, as well as in the, also at Zastava built under license, Campagnola was used.
 It is unclear whether the successor (from about 1963, as Fiat 615 N1) only with the 1.9 liter petrol engine (such as 615 B) was built, with a diesel engine.
The Duramax is a General Motors diesel engine family for trucks.
 The 6.6-liter Duramax is produced by DMAX, a joint venture between GM and Isuzu in Moraine, Ohio.
 The Duramax block and heads are poured at The Defiance GM Powertrain foundry in Defiance, Ohio.
 This engine was initially installed in 2001 Chevy and GMC trucks, and has been an option since then in pickups, vans, and medium-duty trucks.
 In 2006, production at Moraine was reportedly limited to approximately 200,000 engines per year.
 On May 9, 2007, DMAX announced the production of the 1,000,000th Duramax V-8 diesel at its Moraine facility.
The Mercedes-Benz 170 S is a luxury car which was produced by Mercedes-Benz from 1949 until 1955 in various gasoline and diesel powered forms.
 It was initially offered with a 1.8 liter version of the 1.7 liter inline-four cylinder M136 engine used in the slightly smaller production type 170 V.
 It was the first Mercedes-Benz to carry in its name the suffix “S” (for "Sonder modell" (Special model) denoting a superior level of comfort and quality.
 As such, its intended market was successful business owners and company directors.
The SIN R1 is a sports car made by Bulgarian manufacturers SIN Cars.
 FIA certified tube frame construction, carbon fiber body and active real spoiler.
 It came with a 3 different engine choices – LS3 (6.2 liter N/A V8), LS7 (7.0 liter N/A V8) and a LS9 (6.2 liter supercharged).
 Transmission is only one 6 speed manual.
 The car weight is just 1250 kg (2 755 lbs) and has a top speed of 300 km/h (187mp/h).
The Detroit Diesel Series 60 is an inline-six 4 stroke diesel engine that was first produced in 1987.
 It departed from most on-highway engines, by being an overhead camshaft engine and having full "drive by wire" electronic control.
 In 1993 it became popular on many Charter buses in the US at 11.1 L .
 In 1993, the 11.1 L version was rated at 350 bhp (but would produce 15 more if the cruise control was engaged).
 It was also available in 12.7 L at the time.
 Both engine sizes were also used in truck and tractor-trailer applications.
 In 1998, the 11.1-liter Detroit Diesel Series 60 was discontinued.
 Once the 11.1-liter Series 60 was discontinued, the 12.7-liter Detroit Diesel Series 60 became the motorcoach application.
 Starting in the late 1990s, Neoplan made the Series 60 as an available engine for their high-floor and low-floor articulated buses - the AN460A and AN460LF.
DMAX of Moraine, Ohio, is a manufacturer of diesel engines for trucks. DMAX, originally announced in December 1998, is a 60-40 joint venture between and operated by General Motors and Isuzu.
 Diesel engine production started in July 2000.
 The company's Duramax V8 engine has been extremely successful for GM, raising that company's diesel pickup market share to 30% in 2002, up from approximately 5% in 1999.
