Changes for the 2014 season

Option tyres
The use of the option tyres provided by DTM’s exclusive tyre partner Hankook – that again may solely be used in the races and for a minimum of one stint – has been limited to 50 percent of the race distance. Following a safety-car period, the drivers who were racing on these tyres when the safety-car was sent out have got six laps time to pit for fresh tyres, even if they would cover more than 50 percent of the race distance, in this case.

Obligatory pit stop
With immediate effect, the number of obligatory pit stops is reduced to one (previously two) that has to be executed in the second third of the race. Making the obligatory pit stop during a safety-car period is prohibited. Following the safety-car period, the drivers have got six laps time for coming in for their obligatory pit stop, even if this should mean that the stop is made after the time window for the obligatory pit stop has closed.

The qualifying session comprises only three phases, this year. The individual time trial that had to be contested by the fastest four drivers (Q4) in the previous years has been nixed. The new schedule:

  • Q1, 13 minutes, contested by 23 drivers, with the five slowest being eliminated; seven-minute break
  • Q2, 11 minutes, contested by 18 drivers, with the 10 slowest being eliminated; eight-minute break
  • Q3, 11 minutes, the eight fastest drivers battle it out for the pole

The roll-out is held on Friday in two 15-minute sessions. The cars are divided up into those with even and those with uneven numbers. This means that only one car per team is in action, allowing the teams to focus on one car when it comes to the pit-stop practice.

With immediate effect, the Drag Reduction System (DRS) may be used up to the end of the race.

Performance weights
In the 2014 season, so-called performance weights will be used. Therefore, the minimum weight will be increased from 1,110 kilos by 10 to 1,120 kilos, for the season opener at the Hockenheimring Baden-Württemberg. Depending on the results achieved, a brand has to add up to 10 kilos (a maximum of 5 kilos per race) or may get rid of up to 10 kilos (a maximum of 5 kilos per race). The weights are divided up into 2.5-kilo control ballast blocks made of wolframite that will be mounted on a step in the underfloor located approximately in the area of the drivers’ feet. The use of the control ballast blocks per car is limited to the number stipulated by the regulations for the respective race. The performance-weight distribution is executed as follows:

  • The winner of a race and all the drivers of the same manufacturers’ camp who secured a top-10 result have to contest the next race with an additional performance weight of five kilos and two ballast blocks respectively mounted on their cars. The drivers racing for the same brand as the winner who haven’t made it to the top 10 will have to mount 2.5 kilos and one ballast block respectively, for the following race.
  • For the cars of the second-best brand in a race, the weights remain unchanged.
  • The cars of the third-best brand in a race that made it to the top 10 may get rid of 2.5 kilos and one ballast block respectively, for the next race. While those drivers of the brand that didn’t make it to the top 10 may get rid of five kilos and two ballast blocks respectively, for the following race.

Replacement engines
In 2014, just two replacement engines per manufacturer are allowed instead of one replacement engine per team. Each of the ten engines – and nine engines respectively in the case of Mercedes-Benz – must be used in a minimum of four events. The maximum of engines a driver may use over the course of the season is limited to three.

Vehicle homologation
Following the third race, the vehicles will be homologated an additional time and at this point in time, more components will be defined than in the general homologation on 01st April, 2014.
