Transparent Regulations

With a thrilling race format, DTM will provide its fans enthralling motor racing, with the well-thought-our regulations making for neutrality and transparency.

DRS

The Drag Reduction System is supposed to increase a vehicle’s top speed for a short time, thus supporting a driver when trying to pass the car driving ahead of him. To do so, the rear wing is tilted down by 18 degrees and consequently, the downforce is reduced. The system may be used three times per lap and wherever the driver feels the need to do so while the gap to the car ahead allowing a driver to activate the DRS mustn’t amount to more than a second. The distance between the cars always will be measured at the start / finish line. To keep the car stable in corners and increase the downforce should it prove to be necessary, the system automatically is deactivated if a driver brakes or if the lateral forces exceed a certain value. Following the start of the race, the field will be enabled at the end of lap two. Should the safety-car have been out, the DRS will be enabled right after the safety-car returned to the pit-lane. Other than last year, the DRS activations are limited with the number of allowed activations changing depending on track length and race length.

Radio

Drivers and teams may communicate with one another throughout the event via radio. DTM’s German TV partner, ARD, offers the TV audience the chance of partially listening to what teams and drivers are talking about. At the official website, DTN.com, selected channels also can be listened to.  Data transfer while the car is driving, however, is prohibited. 

Parc-Fermé

After having completed the first timed qualifying lap, the vehicles are subjected to the Parc-Fermé regulations.  Up to the start of the race, any changes on the cars are prohibited. After the race, all the cars that were scored again are subjected to the Parc-Fermé regulations, with any changes on the car being prohibited. Between race one and race two, the mechanics have to comply with a defined rest period. In this period of time, the cars remain covered. 

Performance weights

Performance weights have been used since the beginning of the 2014 season. The performance-weight regulations were fundamentally changed, for the 2016 season. In the future, the performance weights will be determined in the qualifying session and will conform to the true competitiveness of a car instead of being based on its result in the previous races. At Hockenheim, the Audi and Mercedes-Benz vehicles will start into the first qualifying session with a weight of 1,120kg while the BMWs will contest the first qualifying session because of a rule adaptation with a weight of 1,112.5kg.
At first the driver who set a manufacturer’s fastest theoretical lap will be used for the allocation of the performance weights. This means that three theoretical laps will determine the performance weight allocation. Crucial for the allocation is the percental difference between the three competitors. The maximum a driver must take aboard his car or may get rid off amounts to five kg. Compared to the first qualifying session of the season, the maximum of weight a car may get rid of adds up to 15kg and the maximum weigh adds up to 1140kg.

Obligatory pit stops

The race on Saturday will be contested without an obligatory pit stop. while the drivers have to come in for an obligatory stop in the Sunday round. In this stop, all the four tyres have to be changed. The stop has to be made roughly in the second third of the race. A special chart will provide the time frame for the respective circuit. At Hockenheim, for instance, the obligatory stop must be made not earlier than on lap 12 and not later than on lap 27 while the car may come in for the obligatory stop from lap 27 to lap 51. Obligatory pit stops mustn’t be made during a safety-car period. When the safety-car comes in, the drivers have got five laps to come in for their obligatory pit stops. This also is the case if this means that the stop will be made outside of the prescribed pit-stop time frame, in this case. Since the 2012 season, refuelling during the race has been prohibited for safety reasons.   

Scoring system

The scoring system for both races is identical, with the points being awarded according to the following format: 25-18-15-12-10-8-6-4-2-1. There aren’t any extra points awarded for the fastest race lap or the pole position and there also aren’t any void results.

Qualifying

Prior to each race, the drivers have to contest a 20-minute qualifying session. It’s up to the driver to decide how many laps he is going to complete and how many of the sets of tyres available to him he is going to use. The pole is secured by the driver who set the fastest lap time.

Tyres

Every driver will have available a certain number of Hankook Ventus slicks and wets for a DTM race meeting, comprising practice session, qualifying sessions and races. On the first day of the respective event, the tyres are raffled off to the competitors by the scrutineers. For the two qualifying sessions and the two races, every driver has six fresh sets of tyres at his disposal and it’s up to him when and how he uses these sets.

Races

Two races are contested per weekend, with the scoring system for both races being identical. The race on Saturday lasts 40 minutes and the drivers haven’t to come in for an obligatory pit stop. The duration of the Sunday race adds up to 60 minutes and every driver must come in for an obligatory stop. During this pit stop, all the four tyres have to be changed. 

Safety Car

The safety car is used for avoiding race stoppages. When the safety car is ordered to go out, all the marshals show waved yellow flags and the shield ‘SC until the safety car is back in the pit lane. The safety car goes out onto the track with activated flashing lights and takes the position in front of the race leader. On the lap when the safety car will return to the pit lane, the yellow flashing lights are switched off. After the crossing of the finish line, accompanied by the showing of the green flag, the race is on again. Overtaking and coming in for obligatory pit stops during safety-car periods is prohibited. 

Slow Zones

The track is divided into several sections, each of them starting in or right after slow corners. When a car gets off the track, the other drivers are informed by yellow flags, warning displays, light signals and a countdown on the display in their cars when approaching the relevant section. When they cross the yellow slow zone line, overtaking is forbidden in this section and an 80kph speed limit is in force. To make driving easier, there is a button on the steering wheel working like the cruise control in a production car and making observing speed limit easier. is observed, just like with a regular cruise control. When the recovery of the stranded car has been finished, drivers are informed by green flags and light signals that they can accelerate to race speed again.

Start

The standing-start format is used for both races. The starting grid is formed on staggered rows and according to the result of the respective qualifying session. Prior to the start, the field completes a formation lap that is completed by the drivers in the starting-grid order. During this lap, the drivers work on getting their tyres and brakes to working temperature. Overtaking is prohibited. Cameras survey every single slot on the starting grid to detect any jump start. Jump starts are penalised with drive-thru penalties. 

Numbers

Prior to the 2015 season, every driver was allowed to select his number. The drivers will keep these numbers throughout their DTM careers. In exceptional cases, however, change requests will be allowed for. The #1 remains reserved for the reigning champion.  

Speed

During the entire event, the pit-lane speed limit amounts to 80kph. There are exceptions for particularly narrow pit lanes such as the one of the Norisring where the pit-lane speed is limited to 60kph. 

Crash recorder

All the cars of the latest generation have to be equipped with crash recorder. The competitors are obligated to enable the scrutineers to readout the control crash recorders at any time. 

Rankings

DTM comprises three season rankings: the title DTM Champion is awarded the driver with the biggest number of points on his tally. The title DTM Team Champion is secured by the team whose two drivers jointly scored the biggest number of points. And all drivers of a brand who made it to the top 10, in a race, score points for the title DTM Brand Champion.
