The DTM faces in 2017, a remarkable change in its rules
technical
. The new cars of the category are now more powerful, less aerodynamic
and come with tires with a higher wear and tear. A summary quite simple and
that however serves to get an idea of the great goal of the developer of the
contest, to give more prominence to the pilots with the design of more cars
reactive, sensitive and difficult to conduct
. For this reason, the DTM has
published a series of keys to understanding the path followed at the technical level
by Audi, BMW and Mercedes
at the time of creating your new DTM.

Motor

Audi Sport, BMW Motorsport, and Mercedes-AMG are keeping their
blocks V8 4.0-liter
, but for the first time, these engines will pay for
on top of the 500 horsepower of power. To get this performance boost has gone on to use a flange 29 mm in place of the flange
admission of 28 mm that was used until now. Have also been allowed to
some substantial improvements in specific areas of the intake system with the
order gaining power without losing reliability, every time that the engines must survive
the full season without major modifications that do not address their own
maintenance.

Aerodynamics

The new regulation has reduced the aerodynamic drag, or better said, has reduced the downforce of the cars of the DTM. In this aspect have modified the geometries of the front splitter, flat bottom and diffuser, as well as the height of the body. All in all, the main visible change is the arrival of a new rear spoiler and a new DRS system of two planes, which allows for differences most noticeable between the aerodynamic load on the curve and the tip speed in a straight line. The new DRS, more cash, promises greater possibilities of adelantamiento.

Neumáticos

despite the greater demands that will face the tire with more powerful cars with less downforce, Hankook has designed some new compounds more soft, and therefore offer more grip in the first instance, something to take into account in the classification or in the first few laps of the race. All in all, the key of the new tires Hankook are its greatest degradation, which will force a better management of the gums on the part of the pilots. These tires Hankook are inexorably associated with the new rims ATS Wheels, common to the three manufacturers.

common Components

One of the technical aspects that has marked the evolution of the DTM in recent years is the use of elements and components common. In this aspect, more and more parts and components that are designed and developed jointly by Audi Sport, BMW Motorsport, and Mercedes-AMG, always in collaboration with the technicians of ITR. Ahead of the season 2017, the number of common elements is higher still, and have been extended to the area of suspensions. These elements have also been added to the wheels ATS Wheels, as we have referred to above.

the value of The pilot

All these measures are aimed at to give greater importance to the talent of the pilots. The cars will be more critical and will require a greater degree of adaptation to the drivers. After the first test in Portimao and Vallelunga, the riders are in agreement that it is the way and the correct direction for increase the fun inside the car and also the spectacle for the fans. In this aspect, it is also expected that the ITR to make some changes to the sporting regulations to improve the dynamics of the competition and the structure of the weekend. These changes will be announced during the final pre-season test at Hockenheim.
