The McLaren MP4-12C is powered by the M838T 3.8 litre twin-turbo V8 engine, designed and developed by McLaren in partnership with Ricardo. The design of the engine was based on the Nissan VRH35 racing engine used in Le Mans in 1998. However, other than the 93 mm bore, little of that engine remains in the M838T. It produces 592 bhp (441 kW; 600 PS) and 443 lb·ft (601 N·m) of torque. It has a redline of 8,500 rpm, with 80% of torque available at just 2,000 rpm.
When first announced, McLaren claimed that it would have a higher horsepower to carbon dioxide emission ratio than any internal-combustion engine available at the time. McLaren announced a small number of improvements to become available in October 2012, with the option to be retrofitted to existing cars free of charge. The engine now produces 617 bhp (460 kW; 626 PS) and no change to the CO2 emissions which remain at 279 g/km. This power output has also become standard on the 2013 model.

The engine is connected to a seven-speed automatic dual-clutch gearbox made in Italy by Graziano. Dubbed the "Seamless Shift Gearbox" or SSG, the gearbox features a system dubbed "Pre-Cog" that allows the driver to preselect the next gear by lightly tapping the paddle.

McLaren have stated the MP4-12C can accelerate from 0 to 60 mph (97 km/h) in 3.3 seconds and 0 to 200 km/h (124 mph) in 8.9 seconds, however if optional Corsa tires are used acceleration times are further improved on with 0 - 62 mph completed in 3.1 seconds. The car has a top speed of 333 km/h (207 mph) and can brake from 200 km/h (124 mph) to a complete stop in under 5 seconds. Braking from 100 km/h (62 mph) to zero can be done in under 30 metres (98 ft), around seven car lengths.
