order to provide a resemblance to the road cars. Also, in order to save money and provide close racing, many common parts from third party specialists are used, like transmission (from Hewland), brakes (from AP Racing), wheels (from ATS) and Hankook tyres (see below). The all-important aerodynamic configurations are tested in wind tunnels before the season, brought to an equal level, and kept that way throughout the season. DTM cars adhere to a front engine rear-wheel-drive design (similar to public legal road car). A roll cage serves as a space frame chassis, covered by CFRP crash elements on the side, front and rear and covered by metallic bodywork. They have a closed cockpit, a bi-plane rear wing, and other aerodynamic parts such as front splitter, side winglets and hood holes (see also on Aerodynamics section for more details). The price of one current DTM car is normally €600,000-€5,000,000. Aerodynamics All Deutsche Tourenwagen Masters cars aero packages are completely assembled. The car floor underbody is flat. Serratured side front fenders are included along with triple-decker front side winglet flicks, multiple side winglet flicks and multiple rear winglet flicks. The 2017–2018 generation of rear wing for all Deutsche Tourenwagen Masters cars are slightly wider, bi-plane wing and also parallelogram rear wing end plate. Since 2019 season onwards, the new generation of rear wings are wider than 2012–2018 generation of rear wing, single-plane wing and uniquely shaped rear wing plate. DTM cars have included a Drag Reduction System since the 2013 season (similar to Formula One) for helping the driver to overtake. The HYLO (High Yaw Lift-Off) aerodynamic safety is integrated on the rear wing for all Deutsche Tourenwagen Masters cars started form 2020 season onwards. Tyres Previously Hankook and Dunlop Tyres were the tyre partner and supplier of DTM from 2000 to 2010 seasons (Dunlop) and 2011 to 2020 seasons (Hankook), carrying the SP Sport Maxx (Dunlop 2000–2010) and Ventus (Hankook 2011–2020) brands respectively. The DTM runs the bespoke compounds and same size as LMP and GT cars since 2000 and re-profiled in 2012. The current front tyre sizes are 300/680-R18 (11.8/26.8-R18) and the rear tyre sizes are 320/700-R18 (12.6/27.9-R18) (previously front tyre sizes were 240/650-R18 (9.45/25.6-R18) and the rear tyre sizes were 280/660-R18 (11.0/25.6-R18) in 2000–2003 later front tyre sizes were 265/660-R18 (10.4/25.9-R18) and the rear tyre sizes were 280/660-R18 (11.0/25.9-R18) in 2004–2010 and later front tyre sizes were 260/660-R18 (10.2/25.9-R18)
