context_page_description: The Mercedes-Benz SLR McLaren is a grand tourer jointly developed by German automotive manufacturer Mercedes-Benz and British automobile manufacturer McLaren Automotive and sold from 2003 to 2010. When the car was developed, Mercedes-Benz owned 40 percent of the McLaren Group and the car was produced in conjunction between the two companies.
  SLR is an abbreviation for "Sport Leicht Rennsport", a homage to the Mercedes-Benz 300 SLR which served as the car's inspiration. The car was offered in coupé, roadster and speedster bodystyles with the latter being a limited edition model.
context_section_description: The SLR features active aerodynamics; there is a spoiler mounted on the rear integral air brake flap. The spoiler increases downforce depending on its angle of elevation (angle of attack). At a set speed, the spoiler/brake automatically raises to 10 degrees (15 degrees in the 722 edition), when demanded via the driver's switch, the elevation can be increased to 30 degrees (35 degrees in the 722 edition) for increased rear downforce, at the cost of increased steady state drag. The car has a flat underbody and a rear diffuser for improved downforce. Due to this, there was no other place for the exhaust pipes to exit, other than the sides of the car, making it another unique feature of the SLR.
