Factory BMW driver Augusto Farfus laps in 6:14 - while high-fiving his passenger.

It may seem ludicrous to suggest a 6:14 lap of the Nurburgring Nordschleife, even just from Bridge to Gantry, is a bit slow. But you get the feeling that, had the driver been taking things a bit more seriously, he could have gone a lot faster.

The driver in question is factory BMW racer Augusto Farfus, who took to the ‘Ring in his Team MTEK M4 DTM machine. And it’s a bit of a monster, with a 4.0-liter, naturally aspirated V8 spitting out 480 horsepower (358 kilowatts), a race weight of just 2,600 pounds (1,180 kilograms), and massive downforce. They may be called touring cars, but DTM racers are, in effect, front-engined single-seaters.

The point here, though, wasn’t to set a lap record. Instead, Farfus was filming a promo for team sponsor Shell’s Helix oil. Hence the vast array of cameras in the M4’s cockpit and the passenger. Who seems to be commentating and having an absolute ball with it, punching the air and high-fiving Farfus as he tackles corners at 160 miles per hour (257 kilometers per hour). At least.

Notice, too, how Farfus slows down considerably at the Flugplatz - presumably a camera was positioned there.

Brazilian ace Farfus has form at the ‘Ring, winning with the 24 Hours race in 2010 in a factory M3 GT2. He has also won races in the DTM and the World Touring Car Championship. Unusually, be made the leap to sedan racing straight from winning the European Formula 3000 title in 2003, and has been with BMW since 2007.

It would be interesting to see just how fast a modern DTM car could go around the ‘Ring. There are a few sequences of corners where Farfus is up to full-speed, flat-out in sixth gear at about 190 mph (306 km/h), and the M4 is welded to the road. There is clearly a much faster lap in the car.

Indeed, so much faster that Stefan Bellof’s unofficial lap record of 6:11.13, set in a Porsche 956 during qualifying for the 1983 Nurburgring 1000 km, could well be obliterated.
