DTM reveals tweaks to cut downforce
DTM has revealed its technical changes for this season which include aero tweaks aimed at cutting downforce by a third. The championship regulations have been changed with the goal of improving racing, and are focused on bringing the skills of the drivers to the fore.
The simplification of aero comes in this season, the last season that Mercedes will compete against BMW and Audi for the title. The changes have been brought in following agreement from the three participating manufacturers after talks regarding the abolishment of the series’ performance weights system, which was finally dropped before the last two rounds of last year.
The technical changes themselves were focused on the cars’ aero packages, and demonstrated by graphics from DTM. At the front the cars will still be equipped with an aero flick, albeit a single one that is smaller than last year’s double flick. The front spoiler has also been adjusted. On the sides of the car, the side duct has been simplified, while the end plate in the area below the doors has been removed, elsewhere, other add on parts have also been taken away.
Away from the aero side of things, the series now stipulates a reduction in the minimum total weight to 1115KG, while the number of engines allowed has been increased to eight.
“The engines used in DTM have been designed for maximum mileage and we want to prevent that the engines exceed this run-time. ITR increased the race calendar from nine to ten race meetings for the coming season, with the Brands-Hatch weekend being a two-day event with no Friday practice session. This means that we are talking about 450 to 500 kilometres more than in the past. To respond to this situation we opted for the most favourable solution. Instead of seven the manufacturers now have eight engines for their six cars that may be changed without penalty,” explained Michael Bernard, head of DTM’s Technical Department.
