With 617 hp and 553 lb-ft of torque going to all four wheels via an eight-speed automatic transmission, the specs of the BMW M8 Gran Coupe make for impressive reading - and ballistic performance. The BMW M8 Gran Coupe's 0-60 sprint is dispatched in three seconds dead, and it headbutts the speed limiter at 155 mph before you know it. The top speed can be raised to 190 mph at an extra cost. It's all accompanied by an intoxicating V8 soundtrack bellowing from the M Sport exhaust. The stability control has an M Dynamic mode that cuts in later to allow for more slip during ten-tenths driving. For even hairier tail-out antics, the xDrive can disconnect the front wheels and switch to an RWD mode. On paper, it's faster than an RS7, but it's a close-run thing in the real world, where the Audi overperforms and covers bumpy ground faster due to its more compliant suspension.
The same basic 4.4L twin-turbocharged V8 found under the hood of the M850i is used in the M8, but with the wick turned up by almost 100 hp. The eight-cylinder engine of the BMW M8 Gran Coupe develops 617 hp. This is accompanied by 553 lb-ft of torque and sent to the xDrive AWD system via an eight-speed automatic transmission with launch control. An RWD drift mode is available too. The engine is extremely refined when cruising but instantly fires its grunt to the road with an angry roar if you put pressure on the throttle, as one would expect from an M car worth it's salt. BMW is still the master of calibrating the trusty ZF eight-speed automatic, and it's nearly as sharp and responsive in the M8 as some dual-clutches out there.

You don't buy an M8 for its fuel economy, but the M8 Gran Coupe's gas mileage and MPG figures are relatively decent for what it is, with estimates of 15/22/17 mpg from the EPA for the city/highway/combined cycles. You'll watch those figures plummet dramatically if you drive it with enthusiasm, however.
With a 20.1-gallon fuel capacity, the average M8 Gran Coupe should have a range of 342 miles on the combined cycle. This high-boost V8 drinks premium gas only.

One would imagine that the fuel-consumption figures of the M850i and M8 Gran Coupe models are comparable because they both use a 4.4-liter twin-turbo V8 engine and xDrive all-wheel-drive system. However, the M8's EPA estimates of 15/22/17 mpg on the city/highway/combined cycles are noticeably heavier than the M850i's 17/24/19 mpg figures. The more aggressive M tuning leans towards performance and not economy, and this makes quite a difference, even in everyday driving.
Due to the high-boost, high-compression performance engine used in the M8, nothing but fuel of the highest octane will do, so you have no choice but to buy Premium gas.
