Understeer and oversteer are vehicle dynamics terms used to describe the sensitivity of the vehicle to changes in steering angle associated with changes in lateral acceleration. This sensitivity is defined for a level road for a given steady state operating condition by the Society of Automotive Engineers (SAE) in document J670 [ 1 ] and by the ...
To compensate for the uneven (35/65) weight distribution caused by the rear-mounted engine, DeLorean used rear wheels with a diameter slightly greater than the front wheels. Before that was the rear-engined Škoda's from Škoda 1000MB (produced from 1964) to Škoda 130/135/136 (produced until 1990) or the Polski Fiat 126p (produced until ...
Oversteer – the rear wheels tend to crawl or slip towards the outside of the turn more than the front. The driver must correct by steering away from the corner, otherwise the car is liable to spin, if pushed to its limit. Oversteer is sometimes useful, to assist in steering, especially if it occurs only when the driver chooses it by applying ...
Negative values are over-steering, positive values are under-steering, for that axle. If the under-steer contribution of the rear axle is greater than that of the front axle you get negative under-steer, which is known as oversteer. The analysis is only applicable while the parameters remain constant, and thus only up to about 0.4 g.
understeer and oversteer where front or rear wheels lose traction during cornering, causing a vehicle to follow a larger or smaller turning radius. burnout where a vehicle slips or spins its tires during acceleration. lockup where a vehicle skids during braking (with or without directional or yaw changes).

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 ...
RMR layout; the engine is located in front of the rear axle. Rear Mid-engine transversely-mounted / Rear-wheel drive. In automotive design, an RMR, or rear mid-engine, rear-wheel-drive layout is one in which the rear wheels are driven by an engine placed with its center of gravity in front of the rear axle, and thus right behind the passenger compartment.
