In less than two weeks, BMW will unveil to the world the new 2012 BMW M5. To be first introduced in a concept form, the M5 will make its world debut at the Shanghai Auto Show in April, followed by the production model at the Frankfurt Auto Show.
In the mean time, BMW continues its field tests and another M5 prototype was spotted in California. Featuring the M exclusive Silverstone paint and rear-seat entertainment, the M5 is going through the last stages of the testing process. The Final Evaluation Phase (FEP) will end later this summer, just in time for the world debut.
The next generation 2012 BMW M5 drops the fans-favorite V10 naturally aspirated engine in favor for a V8 turbocharged engine. The powerplant in the F10 M5 is based on the same unit found in the BMW X5 M and X6M, the twin scroll twin turbo version of the N63, known as the S63. The 4.4-liter V8 twin-scroll unit will peak at 578-horsepower and 530 lb-ft of torque. The 0-62 mph dash should take about 4.4 seconds, but official track times will not be available until late 2011.
The M5 receives complex aerodynamics features. Similar to the Air Curtain introduced in the 1 Series M Coupe, the F10 M5 features a specially designed front apron and trunk link. Design wise, the F10 M5 gets front-end M treatment with the usual aggressive bumper and large air intakes. The production M5 features a hood with a same sporty look emphasized by concave and convex design lines. At the rear-end, the typical quad exhausts remain with a sculpted diffuser and central intake.
The new M5 is also said to have a new Limited Slip Differential (LSD) that further improves traction. In the engine department, the same power unit rumored for months, based on the X5M and X6M engine which produces more than 555 horsepower but up to 565. The maximum torque should come to about 700 Newton meters. The engine is matted to a 7-speed DCT transmission.
