# Isuzu Giga

The Isuzu Giga (Japanese: いすゞ・ギガ) is a line of heavy-duty commercial vehicles produced by Isuzu since 1994. Outside Japan it is known as Isuzu C/E series and Isuzu S&E series. It was formally known as the Isuzu Heavy-Duty Truck'. Between 1994 and 2016, it was also sold in South America (under the Chevrolet brand as Chevrolet C/E series).

## First generation (1994)

* Introduced in November 1994 as the successor to the 810 series. The model of the motorcycle is KC-C ## series, and the tractor that will appear next year is KC-EX # series. A number representing the model is entered at the end of the model number. (Example: KC-CXZ81K1). This number means that it is type 1, and depending on the model such as dump truck, the alphabet is added after the number. For the first time in this model, a GVW 22t & 25t car has appeared. There are two types of cabs, a highway cab for cargo and an off-road cab for dump trucks. The highway cab has headlights on the bumper side. While the majority of cabs were still equipped with headlights, this giga can be said to be the forerunner of the style of equipping bumpers with headlights, which is now commonplace. The cab design, doors and lights are also the same as the 320 series forward that appeared in February of the same year. The rear door of the double cab car is 810 . The low-floor 4-axle vehicle is the GVW25t vehicle, which is the first heavy-duty truck in Japan with the same type of all-wheel axis (changed to 19.5-inch after 22.5-inch 265/60 ultra-flat tires). The GVW22t; 20t vehicle is the same as before. Five grades are available, Space Cruiser (dump is King Dump), High Custom, Custom, Standard Specification, Limited, and the highest grade Space Cruiser has electric curtain, wood grain panel, synthetic leather winding steering & It was equipped with a shift knob, etc., but the lowest grade Limited was a one-seater specification .
* 1995 : Added semi-tractor and all-wheel drive vehicle. The semi-tractor is equipped with a special plating molding on the front panel, and the part inside the molding is painted with gunmetal.
* 1997 : It becomes type 2 with a minor change. 2 is entered at the end of the model number (example: KC-EXR82D2). The semi-tractor and gigamax have eight front panel grills. For the first time as a heavy-duty truck, all vehicles are equipped with SRS airbags for the driver's seat as standard equipment. Equipped with discharge headlights. The 6x4 semi-tractor is equipped with the domestic highest 600PS V-type 10-cylinder naturally aspirated engine 10TD1 . The front grille of the off-road cab semi-tractor has been changed from three slits to six holes. Released Gigamax with 4-bag air suspension . The straight-six engine car has a high cab, and the fender rubber has a thick shape. The straight-six cars have a higher cab, a dedicated bumper, headlights at a higher position than usual, and a license plate at a lower position than usual. From this model, the tires of 4-axle low-floor vehicles have a smaller total wheel diameter.
* 2000 : Minor change to medium-term model. Conforms to 1999 emission regulations (KL-). It becomes type 3 (example: KL-EXR52D3). The grille on the front panel of the highway cab has an inverted trapezoidal design, and the engine has been changed from 12PE1 to 8TD1 for the V type and from 6WA1 to 6WF1 and 6WG1 for the straight-six engine. Since most of the models have moved to straight-six engines, the high cab style has been standardized according to the type 2 straight-six engine (there are also low cab specifications for specially equipped vehicles such as tank trucks). In addition, since the off-road cab car with a straight-six engine is a high cab, the front bumper is now diverting the specification without air dam for the highway cab (the headlight part is closed). The snorkel of a straight-six engine car has been changed from an elongated shape to a flat shape.
* June 2003 : There is no change in the design, but it becomes a 4 type with a minor change (example: KL-CYL23T4). Conforms to 2001 noise regulations. In addition to the semi-tractor, the full air brake was standardized and the naturally aspirated V-type engine was removed from the lineup and quickly unified into the intercooler turbo engine. Smoother G setting. Although the speed indicator was abolished, the lens shape of the speed indicator still remains on the high roof car, and it is painted in body color.
* November 2003 : Vehicles equipped with a 6WF1 engine are additionally set to comply with the 2004 emission regulations (new short-term emission regulations). The model is type 5 (example: PJ-CYL51V5Z). KL-No difference in appearance from the car.
* 2004 : Setting of the completed car "G Cargo".
* August 2005 : Minor change to type 6 (example: PJ-CYJ51W6). The front bumper has been changed in appearance. The front bumper for low cab cars of type 1 and 2 is reused, and a spacer of a new part is attached to the top. Conforms to safety standards for lighting equipment (off-road cab is abolished). Bumpers with license plates below the headlights have disappeared. The position of the front license plate of all cars was unified to the same height as the headlights. The lens of the front turn signal was divided into two, the outside was the turn signal, and the back was the fog lamp. Strictly speaking, this combination lamp itself is a diversion of the 2000 MC model Super Dolphin Profia and Space Ranger. It was a change). Previously, the side turn signal installed in the blister fender of the cab had a built-in side reflector, but since the change was made to move only this reflector to the bumper corner, the reflector space of the side turn signal is a dummy. Fully comply with the 2004 emission regulations (new short-term emission regulations, PJ-). Replaced 6SD1 type engine with 6UZ1 type engine. As with Hino Motors ' Profia, which has a partnership with all-wheel drive vehicles to reduce costs, production has been discontinued. As with Profia, UD Trucks (formerly Nissan Diesel Industry) is an OEM of Quon 's all-wheel drive vehicles to meet the demand for snow removal vehicles and agricultural and livestock vehicles that require all-wheel drive vehicles.
* April 1, 2006 : Added 2005 emission regulation compliant vehicles to vehicles equipped with 6UZ1 engine . Expansion of equipment for the completed "G Cargo" and additional settings for the "Super G Cargo" with a short cab and roof bed.
* March 2007 : A minor change was made in advance of a car equipped with a 6UZ1 engine. It is practically 7 type, but for some reason the model is 8 type by skipping 7 (example: PDG-CYL77V8). The grill design of the front lid has been changed to what is called a "6 cube". At the same time, it is also a big feature that the black belt that existed directly under the front window has disappeared. The "GIGA" logo has also been redesigned, and the front logo has been moved from the left side to the right side to share the image with the elf and forward. Low cab specifications are abolished. All vehicle types comply with the new long-term emission regulations, and vehicles that meet the 2015 fuel efficiency standards will be set as the main vehicle types. Newly developed millimeter-wave radar inter-vehicle distance warning device and cruise control as " VAT ". The garnish on the top of the bumper has been changed from black to gull gray.
* June 2007 : A minor change was delayed for vehicles equipped with the 6WG1 engine. An electronic vehicle attitude control system (IESC) is newly adopted for the tractor. 6WF1 type engine is abolished.
* October 2007 : Developed a collision damage mitigation brake that automatically decelerates during dangerous driving to reduce collision damage. Expand IESC to motorcycles.
* February 2009 : Mirrors for cargo vehicles have become aerodynamic, and door turn signals have been downsized and made into clear lenses to comply with the regulations (ECE / R48). In addition, a side monitoring monitor has been added to "VAT".
* May 17, 2010 : Big minor change. It is practically type 8, but the number at the end of the model disappears (example: LKG-CYL77A). The A at the end means that it is the first Giga, and on models other than the long chassis, the alphabet indicating the length of the chassis is attached behind the A. The urea SCR system jointly developed with Hino is combined with DPD to comply with the 2009 emission regulations. As a general rule, powertrains are unified with 6UZ1 type engine. A 16-speed MT with an auxiliary transmission is newly set for the dump truck (CXZ / CYZ). The cab has expanded the front grille area to improve engine cooling performance, and the headlights have been changed to the same ones as the forward increased ton specification car . Also, the 22.5 inch wheels have been changed from JIS standard 8 studs to ISO standard 10 studs.
* October 28, 2014 : Partially improved. VAT / IESC (Electronic Vehicle Attitude Control System) is standard equipment. A short cab is set for the 3-axle vehicle.
