The Northstar LMP motor is a result of GM’s worldwide motorsports program. While the adjustments in the body and skeleton of the second-era Le Mans Prototype are evident, the alterations to the intensely changed powertrain are for all intents and purposes undetectable.
Power for the new Cadillac LMP will originate from an upgraded rendition of the twin-turbocharged 4.0-liter Northstar V8 hustling motor. A modified incitement framework and overhauled barrel heads will supplement the 180-degree crankshaft and updated motor administration framework that were presented in 2001.

By shortening the wheelbase, undesirable changes in the vehicle’s disposition are minimized, permitting the level base to keep up a positive rake edge and create predictable air loads. Wind burrow tests have exhibited significant upgrades in both lift and drag over the original LMP 01.
