2013 BMW M6 Coupe

All-new 2013 BMW M5 Sedan and M6 Coupe are back

After a two-year hiatus, the ultra-high-performance 2013 BMW M5 Sedan and M6 Coupe are back on U.S. shores.

When anyone thinks of high-performance vehicles, the iconic BMW M series cars have to be near the top of the list. After a two-year absence here in the U.S., the vaunted BMW M5 Sedan and M6 Coupe are back for North American performance enthusiasts. And they are back with more power, more athleticism, more luxury and if anyone cares, they are more fuel-efficient. And performance enthusiasts will be happy to know that the new BMW M5 Sedan, M6 Coupe, and M6 Convertible share the most powerful engine ever fitted in a series-produced model from BMW M GmbH.

More power and efficiency from the Twin-Power Turbo M V8

The new twin-power turbo V8 shared by the BMW M5 and M6 has the highest output ever generated by a BMW M car. BMW says the engine produces around 10% higher output than the V10 engine of its predecessors and torque is up by over 30%. At the same time, fuel efficiency has improved by nearly 25 percent. The 4.4-liter engine produces 560 hp versus 555 hp for the S63, with maximum torque of 500 lb-ft.

BMW uses direct fuel injection in the V8 for high performance and fuel efficiency. The fuel direction allowed M engineers to bump up the compression ratio to 10:1. Both models have impressive acceleration. The M6 Coupe will accelerate from 0–60 mph in 4.1 seconds and 4.2 seconds for the Convertible. The M5 will sprint from 0-60 mph in 4.2 seconds (4.3 for the 6-speed manual). The top speed of both models is electronically limited to 155 mph.
