Even more thrust was provided for the Suburban 2500, which featured the Vortec 6000 sporting 300 horses and 355 lb-ft of twist.
GM Vortec engine
Vortec is a trademarked name for a line of piston engines for General Motors trucks. The name first appeared in 1988 on a 4.3 L V6 that used "vortex technology" to create a vortex inside the combustion chamber, creating a better air/fuel mix. Now it is used on a wide range of different engines. Modern Vortec engines are named for their approximate displacement in milliliters.
The Vortec 2200 (RPO codes L43 and LN2) is an OHV straight-4 truck engine. It is entirely different from the Iron Duke having been the last North American iteration of the GM 122 engine. The 2200 uses an iron block and aluminum 2-valve pushrod cylinder head. Output is 120 hp (89 kW) and 140 lb·ft (190 N·m). Displacement is 2,189 cc (2.189 L; 133.6 cu in) with an 89 mm (3.5 in) bore and 88.00 mm (3.465 in) stroke. 2200s were built in Tonawanda, New York.
Hybrid electric vehicles
A pickup truck, often simply referred to as a pickup or pick-up, is a light motor vehicle with an open-top, rear cargo area (bed).
In North America, the term pickup is used for light trucks with a lighter duty chassis and factory built, integrated bed, as well as for coupé utility vehicles, often based on a personal car chassis, but also often on a special dedicated chassis for such use.
Chevrolet small-block engine
A hybrid electric vehicle (HEV) is a type of hybrid vehicle and electric vehicle which combines a conventional internal combustion engine (ICE) propulsion system with an electric propulsion system. The presence of the electric powertrain is intended to achieve either better fuel economy than a conventional vehicle or better performance. There are a variety of HEV types, and the degree to which they function as EVs varies as well. The most common form of HEV is the hybrid electric car, although hybrid electric trucks (pickups and tractors) and buses also exist.
Modern HEVs make use of efficiency-improving technologies such as regenerative braking, which converts the vehicle's kinetic energy into electric energy to charge the battery, rather than wasting it as heat energy as conventional brakes do. Some varieties of HEVs use their internal combustion engine to generate electricity by spinning an electrical generator (this combination is known as a motor-generator), to either recharge their batteries or to directly power the electric drive motors. Many HEVs reduce idle emissions by shutting down the ICE at idle and restarting it when needed; this is known as a start-stop system. A hybrid-electric produces less emissions from its ICE than a comparably sized gasoline car, since an HEV's gasoline engine is usually smaller than a comparably sized pure gasoline-burning vehicle (natural gas and propane fuels produce lower emissions) and if not used to directly drive the car, can be geared to run at maximum efficiency, further improving fuel economy.
The Chevrolet small-block engine is a series of automobile V8 engines built by the Chevrolet Division of General Motors using the same basic small (for a V8) engine block. Retroactively referred to as the "Generation I" small-block, it is distinct from subsequent "Generation II" LT and "Generation III/IV" LS, and "Generation V" (LT/EcoTec3) engines. Engineer Ed Cole, who would later become GM President, is credited with leading the design for this engine.
Production of the original small-block began in the fall of 1954 for the 1955 model year with a displacement of 265 cu in (4.3 L), growing incrementally over time until reaching 400 cu in (6.6 L) in 1970. Several intermediate displacements appeared over the years, such as the 283 cu in (4.6 L) that was available with mechanical fuel injection, the 327 cu in (5.4 L) (5.3L), as well as the numerous 350 cu in (5.7 L) versions. Introduced as a performance engine in 1967, the 350 went on to be employed in both high- and low-output variants across the entire Chevrolet product line.
The Chevrolet Tahoe (and very similar GMC Yukon) are full-size SUVs from General Motors. Chevrolet and GMC sold two different-sized SUVs under their Blazer/Jimmy model names through the early 1990s. This situation changed when GMC rebadged the full-size Jimmy as the Yukon in 1992. Chevrolet waited until 1995 to rebadge the redesigned mid-size S-10 Blazer as the Blazer, renaming the full-size Blazer as the Tahoe. The Tahoe and Yukon gained a new 4-door model slotting in size between the 2-door models and the longer wheelbase and higher passenger capacity Chevrolet Suburban and newly named Yukon XL.
The Chevrolet Tahoe and GMC Yukon currently serve as a part of General Motors' full-size SUV family. Lengthened wheelbase models are available for both as the Suburban for Chevrolet and Yukon XL for GMC. A luxury Denali model joined the Yukon lineup in 1998. As of 2002, a Denali version of the Yukon XL has also been available as the Yukon XL Denali. The Cadillac Escalade is closely related to the Denali models of the Yukon.
