The BMW M4 is an amazing car. With a 424 horsepower twin-turbocharged inline-six, it is hard to believe that anything else can keep up, especially not a three-cylinder hybrid. The BMW i8 has half the cylinders of the M4 and less power (357 hp). Despite being down on power, the i8 has more torque (420 lb-ft) compared to the M4's 406. Both cars have top speeds of 155 mph and both can hit 60 mph in almost exactly the same time. The M4 hits 60 mph in 4.3, and the i8 is just one tenth of a second behind at 4.4 seconds.

You may not exactly cross shop these two cars, but their performance is remarkably similar. We've actually seen these cars line up before. But now Top Gear took them to the airstrip to see what they can do.
