The weight reduction and consequent lowering of the centre of gravity are key to the car's performance on the racetrack.

The proportions typical of the BMW M4 Coupé, such as the long bonnet, long wheel base, set-back greenhouse and a short front overhang, formed the basis for the low and aerodynamic silhouette of the BMW M4 DTM.Aerodynamics plays a vital role in the DTM. After that, production shifted to BMW Plant Regensburg. Type: P48, R4 turbo engine with direct fuel injection; Capacity: 1,999 cc; Weight: 85 kg (basic weight, according to regulations) Bore: between 86 and 90 mm Narrowing air ducts accelerate the airstream flowing through the front skirt, guide it systematically past the wheels, and reduce turbulence around the wheel arches. We’ll see about that.The 2002 Ti racecar of 1969 eventually spawned BMW’s first turbocharged road car, the 2002 Turbo in 1973. Parts like the gearbox, clutch, dampers and rear wing are identical in all DTM cars.

Besides the extra boost, the power gains are all down to efficiency. Thanks to the significantly shorter reaction time compared to conventional filament lamps, the driver behind is given more notice when a driver in front of him is braking. Which means that, compared with the 210kW at 6500rpm of the old girl, the new 2.0-litre manages something like 450kW at a thought-provoking 9500rpm. It should sound amazing.There’s also word of a 5.0-second, 22kW push-to-pass function that should help cure boring races. The flatter rear window optimises the way the airflow approaches the rear wing. However, the BMW Plants in Regensburg and Dingolfing were also involved in the development of the BMW M4 DTM.

The first model made its first appearance in the wind tunnel at the BMW Group's Aero Lab on 22 April – 13 days before the opening race of the 2013 season in Hockenheim. The new components made their first on-track outing in December 2013 – but still within the BMW M3 DTM at that point. The gearbox is one of the standard components, which are used by all the DTM manufacturers.

The focus of the touring car, modified in line with Class 1 regulations, is a state-of-the-art four-cylinder turbo engine.

Mind you, that has involved moving stuff like the starter-motor and alternator to the rear-mounted transaxle (which has improved weight distribution).It’s been said a million times but finishing first involves finishing, so reliability is a key factor in the P48’s design.

The new components made their first on-track outing in December 2013 – but still within the BMW M3 DTM at that point. The power dome on the bonnet is equally striking. The final parts for the chassis of the BMW M4 DTM were in prod… The side of the car extends the dynamic impression created by the front end.
Apparently, the unit is good for 6000km of racing, meaning each car should only need one engine change per DTM season. The first model made its first appearance in the wind tunnel at the BMW Group's Aero Lab on 22 April – 13 days before the opening race of the 2013 season in Hockenheim. The new engine has throttle-by-wire, a dry-sump, intercooler and direct injection using a mechanical pump to create fuel-rail pressures of something like 350 bar which, surprisingly, is no higher than a contemporary BMW road car, yet is still about on par with the pressure created by the best industrial pressure-cleaners.Lightness is another key point and at 85kg, the new engine is super-light.
One of these is the carbon fibre monocoque, which sets the benchmark in terms of safety in motorsport. The lightweight model boasts impressive figures compared to the DTM engines used up to this point: half the displacement, more power, less consumption. And every fraction of a second counts on the racetrack.
