The now classic Mercedes-Benz CLK GTR was introduced into the world of racing back in 1997, but two decades later it’s still one of the most gorgeous cars the German automaker has ever created. This stretched out CLK houses a massive 6.0-liter V12 engine that produces an ear-shattering exhaust note.
While the CLK GTR and CLK LM raced in the FIA GT series and 24 Hours of Le Mans, Mercedes produced 25 road cars from 1998-1999 after the GIA GT1 class was canceled in 1999. This road-going version brought a lot of components over from the racing version, including that massive V12 engine. However, the displacement of the engine was increased to 6.9-liters and the racing air restrictor was removed. This results in 604 hp and 572 lb-ft of torque. At the time, the Guinness Book of World Records regarded it as the most expensive production car ever built, at a price of $1,547,620, which would equate to around $2.3 million in today’s money with inflation taken into account.
Speedracer38 recently filmed a CLK GTR SS’s exhaust as it made its way back to the RENNtech headquarters after a day at the track. This car has a bored-out 7.3-liter V12 that has 720 hp on tap.
