The new DTM regulations that were introduced last year apply again in the 2013 season. From a technical perspective most of the parameters have remained unchanged. The innovations though are striking.
That BMW on its return last year won all the DTM titles can be ascribed to the strong performances of the BMW teams and drivers, but the newly introduced Technical Regulations have played a part in this as well. The regulations were drafted on the premises of Safety, Cost Control, Show and Equality of Opportunities. All of these aspects were fully met in the past season.
For the 2013 season the Technical Regulations largely remain the same. The drivers continue to rely on the specification safety structures that protect them in case of an accident. In addition to the six crash elements at the sides, front and rear, the combination of a specification monocoque and cage with an integrated safety thank provides even better protection. The seat – similar to Formula 1 cars – is installed in the carbon fibre monocoque that is connected to a roll-over cage made of high-strength steel. In the DTM other specification components are used in areas that are not relevant to performance. These parts are limited to around 50 items which, in total, account for about five per cent of all assembly components. The room for development in the areas of aerodynamics, the suspension and the engine thus continues to be large enough to allow clearly unique characteristics.
For the 2013 season the fans in particular can look forward to a number of new features. Especially the option tyres from Hankook and the Drag Reduction System (DRS) will add a further thrill, as both innovations offer better overtaking opportunities and allow greater variances in race strategies. Other changes to the regulations are as follows: In the fourth and last qualifying segment new tyres may be used. In addition, the teams – after Saturday’s qualifying – have to determine and announce the tyres they will be using for the race start.

Brakes The carbon fibre brakes, brake pads and brake callipers are supplied by the same manufacturer (AP) to all teams. Per vehicle three sets of brake discs for the front and rear wheels may be used during a season.
DRS The Drag Reduction System (DRS) is a wing flap that allows a higher top speed to be achieved for a short time. As of the 2013 season this system is to make for better overtaking possibilities.
Electronics All DTM vehicles use the same engine control unit from Bosch. Data transmission while the vehicle is running on track is prohibited.

Fuel Only the fuel prescribed for the respective event (ARAL Ultimate 102) may be used.
Gearbox In the DTM only one gearbox-differential unit – made by Hewland – is permitted.
Safety In the cockpit the driver is surrounded by an innovative combination consisting of a standard monocoque and cage. In addition, each vehicle has crash structures on both sides and at the front and rear. The “HANS” (Head and Neck Support) system has been mandatory since 2002.
Tyres The tyres are exclusively supplied by the series’ partner Hankook. At the front, “Ventus” 300/680 – 18 are used, the dimensions for the rear wheels are 320/710 – 18. Strictly for the race a set of softer option tyres is available that has to be used once. After qualifying the teams have to announce which of the two tyre types they will start the race with.
Weight The minimum weight of a DTM car including the driver, suit and helmet is 1,110 kilograms.
