Here is the full set of our BMW F82 M4 Coupe Concept renders - with a front, rear, and interior view. Enjoy!

Germany based Hartge has released the figures on its ECU software tune for the M5 and M6 good for 642hp and 810 Nm (597 lb-ft), representing an increase of +82 hp and +130 Nm (96 lb-ft) over the factory figures.

Hartge quotes a new 0-62mph time of 4.2 seconds with a top speed of 190mph (305kmh).

This is achieved with the ECU tune as well as a stainless steel exhaust system.

The Hartge F10 M5 below also showcases Hartge lowering springs which lowers the M5 by 25mm front / 20mm rear, as well as the Hartge front lip (still unpainted we hope), side skirts, and carbon fiber mirror covers.

Are you the BMW M4 (F82) Coupe Concept?

Here are results from the Sport Auto performance test comparing the 2013 Alpina B6 (F13) versus the 2013 M6 (F13) coupe.

The Alpina B6 Biturbo (full specs) is powered by BMW’s 4.4L V8 engine rated at 540hp and 730nm torque and top speed of 334 km/h.

The M6 features 560hp and 680Nm torque with a top speed of 305 km/h.

CAR Magazine claims that these 2014 F80 M3 sedan images are the real deal, received from BMW. But, judging by their recent history with a false claim that a F10 M5 image they printed was also the real thing, we’re inclined to think that this may again be a case of crying wolf.

It’s been weeks since the last F80 M3 sightings, but we’ve now spotted the 2014 M3 prototype undergoing winter/cold climate testing and it looks like the testing has advanced to another stage.

M Carbon Ceramic Brakes

For the first time, we see the F80 M3 in a color other than black (Alpine White), which sometimes signals a more advanced stage of testing. Beyond that however, this is the first F80 prototype to sport BMW M Carbon Ceramic Brakes. One can tell that they are ceramic brakes by the brake rotor material and gold brake calipers (a signature color for M Carbon Ceramic Brakes beginning with the current M5 and M6 - more details). To give you an idea of what kind of performance increase may be expected, … CONTINUED

Video of the Hamann exhaust system for the F10 M5. Together with its ECU software tune, it bumps the M5’s power to 720hp and 900Nm (664 lb/ft) of torque.

Now here’s a shade of color that’s rare even among the custom BMW Individual colors that we’ve seen ordered for late model BMWs - Oxford Green, a color that hasn’t been offered as a standard BMW color for years now.

We would never have guessed that it would look so good on the 2013 M6 (F13) coupe, but it actually works pretty well in our opinion. Not many exterior colors can pull off a champagne tan interior such as this, but Oxford Green happens to be one of them.
