Update: Could this be just the M-Sport Package with a Performance Exhaust?
We can’t certainly say if this is the 2012 BMW M5, but judging by some of M-specific elements, we are inclined to believe that the new M5 has just been spotted with no camouflage. Unfortunately, only a rear shot has been provided, but the car resembles the several test mules we have seen in the past months.
The new generation M5 follows the new design language introduced by BMW in the 5 Series Sedan. The design lines continue to flow from front-to-end and they become even more substantiated on the sides where multiple convex and concave shapes give the M5 an extra-dynamic look.
While built on the same platform, F10 as the 5 Series sedan, the M5 features wider fenders, giving the car more muscular and imposing look. The twin dual-exhaust tips are an M trademark and the prototype spotted features them as well.
Even though not shown in this photo, the front-end sports the expected M trademarks with the usual aggressive bumper and larger than normal air intakes. To keep the weight down in this slightly larger model, BMW will make extensive use of carbon-fiber and aluminum parts.
The 2012 BMW M5 is powered by an updated version of the engine found in the BMW X5 M and X6 M. The 4.4-liter V8 twin-scroll powerplant will peak at 578-horsepower and 530 lb-ft of torque. The 0-62 mph dash should take about 4.4 seconds, even though we expect to see lower track times. If the final horsepower numbers will stand, then the new M5 will have 60 horsepower more than the Mercedes-Benz E63 AMG and similar output as the Audi RS6.
