Palbay, the South Carolina-based spy photographer, has spotted the F10 BMW M5 parked next to the new M6 Coupe at the BMW Performance Center in Spartanburg. The 2013 BMW M5 will arrive to dealerships in the next weeks and will carry Manufacturer’s Suggested Retail Prices of $90,695. The 2013 BMW M6 Coupe will also launch this summer and will have a base price of $106,995 (including destination and handling).

Both cars are powered by the high-revving 4.4-litre V8 engine with M TwinPower Turbo technology, consisting of Twin Scroll Twin Turbo technology, cross-bank exhaust manifold, High Precision Direct Petrol Injection and VALVETRONIC fully variable valve control. The cars deliver 560 hp at 6,000 – 7,000 rpm and maximum torque of 680 Newton meters (502 lb-ft) from 1,500 rpm.

Dimensions wise, the M5 Sedan is slightly larger than the sportier M6 Coupe, 4,910 mm vs 4,898 mm. To give the passengers more interior space, the M5 is 13mm wider than the M6 (2119 mm vs 2106 mm).

As expected, the F10 M5 also weighs slightly more than the M6 Coupe, 4,286 lbs vs 4,243 lbs.

We had a chance to extensively test the M5 last year in Barcelona, both on and off-track, and this month we will get behind the M6 Coupe and share with you our impressions.
