With a year left before its official unveiling at the 2012 Geneva Motor Show, the new BMW M5 rendering games continue and it will most likely keep going for a few more months. This time, the fellows over at InsideLine took a shot at visually designing the F10 BMW M5.

The results are a bit less aggressive than what we have seen before, but overall, the rendering incorporates all the M elements we would see on the M5.

While not necessarily portrayed in these photos, sources close to the brand claim that with the new 5er central grille being much larger, the central intake size has been diminished. The wheel arches are also larger in order to add some mass on the F10’s athletic body. A side air intake is placed underneath the character line which climaxes at the wheel arch. The side skirts are more sculptured allowing for good aerodynamics.

At the rear-end, the typical quad exhausts remain with a sculpted diffuser and central intake. A small bootlid spoiler allows the car to remain understated and restrained.

Engine wise, an updated version of the unit found in the BMW X5 M and X6 M will make its way into the F10 M5. The 4.4-liter V8 twin-scroll powerplant will peak at 578-horsepower and 530 lb-ft of torque, 60 horsepower more than the Mercedes-Benz E63 AMG, but the same as the Audi RS6.

The car is rumored to feature a modified version of the M3’s M-DCT system, but a second transmission option might be offered as well.

To keep the weight down, BMW will make extensive use of carbon-fiber and aluminum parts, starting with the a carbon-fiber roof. The car’s construction will be a hybrid of an aluminum spaceframe for the front section and a traditional steel monocoque for the passenger compartment and rear. Up front will be an independent suspension with MacPherson struts, with a multi-link layout for the rear.

The 2012 BMW M5 will debut next year in March wit sales commencing shortly after.
