This Mercedes 190E sedan was built to drift by Dyno Channel in Sweden uing an assortment of BMW and Mercedes parts. The team started by reinforcing the chassis, installed a turbocharged 2.8 L BMW M52TUB28 inline-six, and E46 front subframe and suspension. Last year they replaced the BMW inline-six with a turbocharged 5.0 L Mercedes M119 V8 that makes made 601 horsepower and 809 Nm (596 lb-ft) of torque to the wheels on 0.7 bar (10.1 psi) of boost from a BorgWarner S369SX-E 9180 turbocharger and E85 fuel. The engine features stock internals, stock 11:1 compression, and slightly altered timing. The team is on their third engine. They attribute the first failure to oiling issues and the second to poor engine condition. Behind the engine sits a GS6-53DZ six-speed manual transmission with a Mercedes bellhousing welded on the front and the stock Mercedes differential.
