The 1982 L83 was again the only Corvette engine, producing 200 hp (149 kW) and 285 lb⋅ft (386 N⋅m) of torque from 9.0:1 compression. Since GM did not assign a 1983 model year to production Corvettes, there was no L83 for 1983. [22] This was also the only engine on the 1984 Corvette, at 205 hp (153 kW) and 290 lb⋅ft (393 N⋅m) of torque.
LS2 can also refer to the 1973–1974 Super Duty 455 cu in (7.5 L) Pontiac V8 engine LS2 can also refer to the 1985 Oldsmobile Diesel V6 engine. The LS2 was introduced as the Corvette's new base engine for the 2005 model year. It also appeared as the standard powerplant for the 2005–2006 GTO.
Other problems may be implicated in the case of older vehicles equipped with carburetors. Weak, disconnected, or mis-connected throttle return springs, worn shot-pump barrels, chafed cable housings, and cables which jump their tracks in the throttle-body crank can all cause similar acceleration problems.
The 2020 Corvette C8 was the first Corvette to have a rear mid-engine configuration, [108] GM's first since the 1984 Pontiac Fiero. The base Stingray coupe was introduced on July 18, 2019, with three launch colors, red (with the Z51 Package), white, and blue, and the convertible on October 2 at the Kennedy Space Center , joined by the C8.R race ...
The advent of concern about fuel economy and emissions had major impacts on engine design. Some of the trade-offs reduced throttle response. Most new cars employ a drive-by-wire system, which includes electronic throttle control and can itself either reduce or increase throttle response (Depending on whether or not it's being employed on a performance car).
The 2006 and 2007 CTS-V used the 400 hp (298 kW) 6.0 L LS2 Gen IV V8, similar to that used in the standard Corvette C6. The 2009–2015 CTS-V carried a supercharged 6.2 L LSA variant of the Gen IV V8, producing an SAE-certified 556 hp (415 kW), while the 2016–2019 model carried a supercharged 6.2 L LT4 with 640 hp (477 kW).
Lift-off oversteer (also known as trailing-throttle oversteer, throttle off oversteer, or lift-throttle oversteer) is a form of sudden oversteer.While cornering, a driver who closes the throttle (by lifting a foot off the accelerator, hence the name), usually at a high speed, can cause such sudden deceleration that the vertical load on the tires shifts from rear to front, in a process called ...
A throttle position sensor (TPS) is a sensor used to monitor the throttle body valve position for the ECU of an engine. The sensor is usually located on the butterfly spindle/shaft, so that it can directly monitor the position of the throttle. More advanced forms of the sensor are also used.
