Jay Leno Shows Off McLaren F1 V12 Engine

Even though it’s been out of production since 1998, the McLaren F1 still commands considerable attention from the enthusiast community. It also requires a delicate maintenance schedule, and thanks to Jay Leno’s Garage we get an inside look into the engine of this unique 3-seater hypercar.

Leno’s team had to pull the 6.1-iter BMW 60-degree V12 engine to replace a fuel pump and fuel cell. They also discovered a leak in the VANOS unit, which controls the variable valve timing. With the engine on a stand, all its beauty and sophistication is showcased. The exhaust system is lightweight and a flowing piece of art. The intake system is quite imposing with individual butterflies and a pair of injectors per cylinder, and the magnesium valve covers are as sleek as any casting on the market. The video also provides a peek at the McLaren’s engine bay, which is lined with a gold-foil heat shield.

Leno says the engine is rated at 627 horsepower. Even though it’s naturally aspirated, the McLaren F1 remains one of the fastest production cars ever built with a top-speed clocking of 243 mph. While other faster supercars have been introduced in recent years, they are usually turbocharged.

Check out the video to spend some time with Jay and get a closer look.
