Gallery: The McLaren MP4-12C Engine

In the early days of McLaren’s MP4-12C development, it was suggested that the new mid-engine supercar would use AMG’s 6.2 liter V8. As things got awkward between Mercedes and McLaren though, a mysterious “German-built V10” was rumored to be have replaced the AMG unit under at least one testing prototype. In the end, McLaren built its own engine, the M838T. It’s a twin-turbocharged, direct-injected, 3.8 litre, 90° V8, developing about 600 horsepower at 8,500 RPM. 80 percent of its 442 lb-ft of torque is reportedly available under 2,000 RPM. Also, it looks like mechanical sex.

Interesting that McLaren chose 90 degrees of V out of all the possibilities. Could I order the engine only for my Locus Plethore?

Its a late reply.. but I finally test drived the MP4-12C yesterday! Its the fastest factory road car I ever tested . The car handles brilliant, carbon fiber monocell results a road car with a go-cart like handling.. I would say, the cornering limit of the car is very high. I switch everything into "track mode", I didn't feel the car bumpy at all, this is a result of a piece of engineering art work, lightweight and high power super car. Engine with turbos weights around 150kg . But the car has big turbo lag comparing with GTR, but top ends it will beat the GTR for sure due to V8 fitted with high flow turbos. One thing have to say good about the gearbox . The gear shift is seamless and smooth. This is the best gearbox I ever driven comparing with all other double-clutched gearboxes (like PDK, DSG) . Even with stand still start, the electronic clutch is very smooth. This shows Mclarens effort in their software engineering for clutch control during launch. Braking power..... absolutely amazing . With the car's weight, it just brakes like a cart with carbon ceramic brakes and 6 piston calipers . Overall, good race car, but difficult to sell....

ToolGuy "At risk of oversimplification, a heat pump takes ambient air, compresses it, and then uses the condenser’s heat to warm up the air it just grabbed from outside."• This description seems fairly dramatically wrong to me.
SCE to AUX The UAW may win the battle, but it will lose the war.The mfrs will never agree to job protections, and production outsourcing will match any pay increases won by the union.With most US market cars not produced by Detroit, how many people really care about this strike?

Dusterdude The Detroit 2.5 did a big disservice by paying their CEO’s so generously ( overpaying them ) It is a valid talking point for for the union ) However , the bottom line - The percentage of workers in the private sector who have a defined benefit pension plan is almost non existent - and the reason being is it’s unaffordable ! . This is a a huge sticking point as to have lower tier workers join would be prohibitive ( aside from other high price demands being requested - ie >30% wage gain request ) . Do the math - can a company afford to pay employees for 35 years , followed by funding a pension for a further 30 years ?
