2013 McLaren MP4-12C Spider

Power comes from the same beastly twin-turbo 3.8-liter V8 as the coupe. It can spin all the way up to 8500 rpm and produces 617 horsepower and 443 lb-ft of torque. Peak twist is available at 2,000 revs, so flirting with the redline isn't necessary for strong acceleration.
Zero-to-60 mph flashes by in just 3.1 seconds, while completing the quarter-mile takes 10.8 ticks.
