Team Rühle Racing built this custom Audi RS6 called “ProRS6” to achieve high-6’s in the quarter-mile. The project starts with a custom tubular chassis with a 4-link rear suspension. Under the carbon fiber shell front is a turbocharged 3.2 L 2JZ inline-six producing 1999 hp (1470 kW) and 1635 Nm (1205 lb-ft). The motor features a Bullet billet block, forged pistons and rods, HeadGames Motorworks head, and dry sump system. A Precision XPR 98/103 ProMod turbocharger provides 65 psi (4.4 bar) of boost. The motor runs on methanol and features three ID2600 injectors per cylinder (18 total). Behind the motor is a M&M Transmission TH400 three-speed automatic transmission and R35 GTR billet transfer case. Power is split between an R35 GTR billet front differential and Strange rear end.
