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.
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.
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 ...
Diesel engine runaway is an occurrence in diesel engines, in which the engine draws extra fuel from an unintended source and overspeeds at higher and higher RPM, producing up to ten times the engine's rated output until destroyed by mechanical failure or bearing seizure due to a lack of lubrication.

Pontiac added the drive-by-wire 400 HP LS2 V8 for the 2005 and 2006 model years at no additional cost. Additional upgrades also consisted of stainless steel dual exhaust outlets, larger Corvette-sourced PBR brakes with EBD, larger front vented rotors with vented rear rotors, and functional heat extractor hood scoops.
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).
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.
The C5 was also the first Corvette to incorporate a drive-by-wire throttle; and variable-effort steering, whereby the assist level of the power steering is varied according to vehicle speed (more at lower speeds, less at higher speeds). Also notable, though rarely discussed, the C5 generation was the first model to adopt the parallel or 'tandem ...
