Audi RS5 DTM
Audi RS5 was winning car of the DTM 2014 season. It was developed in 2011 and, with few modifications, has been raced in DTM seasons from 2012 as a respond to the new Techincal Regulations of the competition. Audi RS5 was designed by former Audi Head of Research and Development Wolfgang Durheimer and was revealed at Frankfurt moto show in 2011. Designer had to meet three prerequisities to meet: best possible safety, cost reduction by up to 40 per cent and a spectacular look.
After the 2012 season, the vehicle was renamed RS5 DTM, correspond with the Audi RS5 production model and made his DTM debut next year. In March 2014 the RS5 DTM was redesigned and launched during Geneva Motor Show.
Audi RS5 DTM model is flatter and wider than previous A4 model which won five titles from 2004 to 2011. The chassis underneath the full-carbon body is of a hybrid design. The combination of the carbon fibre monocoque and steel cage with front, rear and side crash elements sets standards for a race touring car in terms of safety.
RS5 DTM is powered by an Audi V8 engine delivering around 340 kW (460 hp). Unlike most racing cars competing in the DTM, the RS5 is powered by a naturally-aspirated engine and 2xDOHC camshafts and maybe that was the main reason for the triumph in 2014.
The six speed gearbox is pneumatically operated by paddle shifters on the steering wheel. Integrated into the safety cell of the Audi RS5 DTM is a 118-litre safety tank that allows the distance of a DTM race to be completed without a refuelling stop.
Audi RS5 DTM has independent front and rear suspension, double wishbone suspension, pushrod system with spring-damper unit and adjustable gas pressure dampers.
The possibilities in the aerodynamics area of Audi RS5 are limited. Air flow through the body and complex additional rear wings are not longer allowed. That’s why vehicle reacts less sensitively to body contact and deliver better slipstream.
As further development was possible only to a very limited extent the focus was placed on detailed fine-tuning. Therefore, the fit of the Audi RS5 body parts was optimised in order to avoid gaps and transition areas that would impair the drag coefficient.
