 The engine for the CLR was also a variant of the design used on the CLK LM . The GT108C 32 valve V8 was loosely based on the M119 engine used in Mercedes @-@ Benz road cars at that time . A previous variant of the M119 had won Le Mans for Mercedes in 1989 . Displacement was increased from 5 @.@ 0 L ( 310 cu in ) to 5 @.@ 7 L ( 350 cu in ) to compensate for the new air restrictor limitations in the LMGTP category , which allowed the motor to produce approximately 600 bhp ( 450 kW ; 610 PS ) . The first engine was completed and began testing in December 1998 . The Xtrac 6 @-@ speed sequential gearbox came directly from the CLK LM , while Bridgestone continued as the team 's tyre supplier . The suspension setup from the CLK LM was largely carried over to the CLR , although a central spring was added to the rear suspension .
