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....

  • Jonathan IMO the hatchback sedans like the Audi A5 Sportback, the Kia Stinger, and the already gone Buick Sportback are the answer to SUVs. The A5 and the AWD version of the Stinger being the better overall option IMO. I drive the A5, and love the depth and size of the trunk space as well as the low lift over. I've yet to find anything I need to carry that I can't, although I admit I don't carry things like drywall, building materials, etc. However, add in the fun to drive handling characteristics, there's almost no SUV that compares.
  • C-b65792653 I'm starting to wonder about Elon....again!!I see a parallel with Henry Ford who was the wealthiest industrialist at one time. Henry went off on a tangent with the peace ship for WWI, Ford TriMotor, invasive social engineering, etc. Once the economy went bad, the focus fell back to cars. Elon became one of the wealthiest industrialist in the 21st century. Then he went off with the space venture, boring holes in the ground venture, "X" (formerly Twitter), etc, etc, etc. Once Tesla hit a plateau and he realized his EVs were a commodity, he too is focused on his primary money making machine. Yet, I feel Elon is over reacting. Down sizing is the nature of the beast in the auto industry; you can't get around that. But hacking the Super Charger division is like cutting off your own leg. IIRC, GM and Ford were scheduled to sign on to the exclusive Tesla charging format. That would have doubled or tripled his charging opportunity. I wonder what those at the Renaissance Center and the Glass House are thinking now. As alluded to, there's blood in the water and other charging companies will fill the void. I believe other nations have standardized EV charging (EU & China). Elon had the chance to have his charging system as the default in North America. Now, he's dropped the ball. He's lost considerable influence on what the standardized format will eventually be. Tremendous opportunity lost. 🚗🚗🚗
  • Tassos I never used winter tires, and the last two decades I am driving almost only rear wheel drive cars, half of them in MI. I always bought all season tires for them, but the diff between touring and non touring flavors never came up. Does it make even the smallest bit of difference? (I will not read the lengthy article because I believe it does not).
