We haven’t spotted the F82 M4 Coupe at the Nurburgring since July, when the F82 was spied for the very first time in public testing. Well, it’s now back at the Ring during an onslaught of BMW prototype testing in the past week, including the F80 M3, F82 M4, F36 4 Series Gran Coupe, F15 X5 M, 3 Series GT, and the M6 Gran Coupe.

Below are the most recent photos and a video of the F82 M4 in testing at the Nurburgring, as well as a recap of what’s known and speculated about the next gen M3/M4 thus far.

Here’s a fun matchup. Watch as the BMW F10 M5 drags against the Tesla Model S to 100MPH. Here are their specs on paper:

Tesla Model S - 443 lb-ft torque @ 0-5100rpm, RWD, 0-60mph 4.4s (factory quoted), 4,647 lbs
F10 M5 - 502 lb-ft torque @ 1500-6560rpm, RWD, 0-62mph 4.4s (factory quoted), 4,288 lbs

The race is a close one and many variables shift the advantage to the Tesla S in such a race. For one, the race is only to 100MPH. Although the Tesla is heavier, it gets full torque to the wheels instantly. You can see the M5 catching up and about to pass at the 100MPH mark, resulting in it winning 1 of the 3 races. If this … CONTINUED

Taking after the Nurburgring M5 Ring Taxi, the Norwegian track Rudskogen has also purchased and prepped a 2013 F10 M5 to serve as its official track car. First modifications have been made to the interior - in the form of a rollcage and Recaro seats all around.

Next up will be the brakes and suspension.

We spoke very recently at length to a trusty source within BMW who is familiar with the development of the upcoming F80 M3 sedan / F82 M4 coupe and we were able to learn the following bits of news:

HORSEPOWER / TORQUE

Regarding power output, the previously estimated 450HP figure is an overestimate. Instead, expect the horsepower output to be in ballpark of the current E90/E92 M3.

What will be increased greatly however, is the torque figure. The F80/F82’s multi turbo inline 6 cylinder engine [recently exposed] will add approximately 100 lb-ft more torque over the current M3 (which outputs 295 lb-ft torque). This would put the new M3/M4 in the range of 395 lb-ft torque. There’s nothing like forced induction for thrust!

Studie AG has also gotten their hands on the F10 M5 and begun work fitting multiple wheels and parts onto their project M5.

The car has been lowered on KW Clubsport suspension and test fitted with 20″ Advan Racing GT, 21″ Advan AVS Model F15, 21″ AC Schnitzer Type VIII, and the full AC Schnitzer aero kit.

Great news for those M5 and M6 owners affected by the faulty oil pump recall. Less than two weeks after the recall was announced, the first oil pump replacements are underway and completed. The first M5POST member has just shared that his replacement pump is in and his M6 already on its way back to him.

EAS has dynoed a 2013 M6 DCT coupe. The M6 with its S63Tu motor is rated from the factory at 560hp / 502 lb-ft torque. This particular M6 put down a max 503hp / 488lb-ft torque (SAE) at the rear wheels. This was achieved on regular 91 octane pump gas and a Dynojet 224xLC.

There are still slots open for free dynos, so check inside if you are from the SoCal area and would like to run your F10 M5 or F12/F13 M6 on the dyno.

Check out this major update to the 2013 M5 (F10) project car by IND. It now features the world’s first carbon fiber roof fitted onto the F10 M5, 20″ BBS FI wheels, KW Clubsport coilovers, carbon fiber Recaro seats, GruppeM air intake system, and 3D Design aero kit, and Full Eisenmann center pipes + rear exhaust installed.

Look for the IND M5 to make its debut at the SEMA Show in Las Vegas next month.
