1988 was the new 4.3-liter, 90-degree, Vortec V6 became an option on all S-10s at midyear, Iron Duke four and 2.8-liter V6. Rated at 160 hp and 235 lb-ft, the fuel-injected Vortec was both smoother and much more powerful than the 2.8-liter V6.
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.
A mid-size car (occasionally referred to as an intermediate) is the North American/Australian standard for an automobile with a size equal to or greater than that of a compact. In Europe mid-sizers are referred to as D-segment or large family cars.
The automobile that defined this size in the United States was the Rambler Six that was introduced in 1956, although it was called "compact" car at that time. The mid-size class then grew out of the compacts of the early-1960s. For example, the Ford Fairlane was referred to at its introduction in 1962 as a compact intermediate because it was barely bigger than its close relative, the Falcon. General Motors' first entries in the class, such as the Oldsmobile F-85, Pontiac Tempest, and Buick Special were not mechanically related to the compact Chevrolet Corvair, but were similar in size.
A V6 engine is a V engine with six cylinders mounted on the crankcase in two banks of three cylinders, usually set at either a right angle or an acute angle to each other, with all six pistons driving a common crankshaft. It is the second most common engine configuration in modern cars after the inline four.
The V6 is one of the most compact engine configurations, shorter than the inline-4 and in many designs narrower than the V8. Owing to its compact length, the V6 lends itself well to the widely used transverse engine front-wheel drive layout. It is becoming more common as the space allowed for engines in modern cars is reduced at the same time as power requirements increase, and has largely replaced the straight-six engine, which is too long to fit in many modern engine compartments. The V6 engine has become widely adopted for medium-sized cars, often as an optional engine where an inline-4 is standard, or as a base engine where a V8 is a higher-cost performance option.
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.
The Chevrolet S-10 is a compact pickup truck from the Chevrolet marque of General Motors. It was the first compact pickup of the big three American automakers. When it was first introduced in 1982, the GMC version was known as the S-15 and later renamed the GMC Sonoma. A high-performance version was released in 1991 and given the name of GMC Syclone. The pickup was also sold by Isuzu as the Hombre from 1996 through 2000. There was also an SUV version, the Chevrolet S-10 Blazer/GMC S-15 Jimmy. An electric version was leased as a fleet vehicle in 1997 and 1998. Together, these pickups are often referred to as the S-series.
In North America, the S-series was replaced by the Chevrolet Colorado, GMC Canyon, and Isuzu i-Series in 2004.
