BMW tests M Lap Timer App with M4 Coupe at Brands Hatch

The 2015 BMW M4 looks to include all the necessary ingredients to offer dynamite driving experience. It's an M car after all. But in today's constantly connected world, the experience of hurtling a car around a track isn't always enough.
We want data, and while there are some solid telemetry apps available for smartphones (notably Harry's GPS LapTimer), manufacturers have been a bit slower to develop their own dedicated mobile telemetry trackers for their performance cars. With the new M4, though, BMW is taking the plunge, allowing drivers to track their lap progress through a new app, creatively called the M Lap Timer.
To show off the program, BMW has recruited touring car racer Andy Priaulx to perform a fast lap in an M4 at the UK's Brands Hatch circuit. The accompanying video doesn't do much to show off the app in action. Rather, it give us a stylized look at the metrics as Priaulx hustles BMW's hottest 4 Series coupe around the circuit.

BMW celebrates with M4 DTM Champion Edition

Go back just a few seasons, and Germany's DTM touring car series was a straight-up competition between Audi and Mercedes-Benz. But BMW rejoined the race in 2012, winning both the drivers' and constructors' titles on its first year back and celebrating with a special matte-black M3 DTM Champion Edition. Last season, it won the constructors' championship but not the drivers', and this year it did the opposite. In short, it's been an impressive comeback for the Bavarian automaker, and to celebrate this year's accomplishments, it's followed up with the new M4 DTM Champion Edition for Europe you see here.
Based on the new M4 coupe - which forms the basis for BMW's DTM challenger as well as its pace car - the Champion Edition is distinguished by its special livery: The orange grille frame, the matte black hood and trunk with multicolored stripes, the black stripes along its shoulder and rocker panel, and the blacked-out 19-inch wheels all to pay homage to champion Marco Wittmann's racecar, as does special lettering on the rear windows.
Other enhancements include black front splitter and skirts, carbon front flaps and mirror caps, rear spoiler and carbon diffuser, while autographed sill plates and carbon interior trim with the car's serial number adorn the cabin. Only 23 examples will be offered, symbolic of the number adorning the winning tin-top racer and the flank of this special edition as well.

BMW M4 Coupe laps 'Ring in 7:52, bests outgoing M3

Comparing Nürburgring Nordschleife lap times is a bit of a black art, especially when looking at times officially set by manufacturers matched against other sources. Driver skill and weather conditions play a huge roll in determining a quality time. Still, it appears BMW fans have reason to celebrate because the new M4 Coupe beat the previous-generation M3 by 13 seconds in a recent test by Germany's Sport Auto magazine.
Sport Auto conducts what it calls the Supertest, where it runs performance cars around the 'Ring and the short course at Hockenheim to create its own database of comparable times. The M4 with a dual-clutch transmission, ceramic brakes and Michelin Pilot Supersport tires managed a quality 7 minutes 52 second lap around the 12.8-mile course, compared to 8:05 from the last M3, according to BimmerPost. The new coupe also beat the magazine's posted times for the Audi RS5 Coupe, which did it in 7:59, and Mercedes-Benz C63 AMG with an 8:01, but couldn't quite match the 7:44 set by a 911 Carrera S. Still, BMW must be somewhat pleased with these results of its new 425-horsepower coupe because it posted the magazine's cover and an image of the time on its official M Facebook page.
While the M4 apparently stands up to contemporaries and predecessors, new generations of the AMG and RS models are reportedly on the horizon. In other words, more tests will come.
