All wrong, has to be the JCB 444 diesel engine, which powered the dieselmax to 350.092mph. Jag and BMW can't make even half of this and how about the Audi R10 Diesel which won Le Mans or the HDi V12 700bhp 885lb-ft diesel from Peugeot which beat Audi and won Le Mans this year
The true crown has to go to the Wartsila-Sulzer RTA96-C turbocharged two-stroke diesel engine, The most powerfull diesel engine in the world with 108,920 hp at 102 rpm and a mind blowing 5,608,312 lb/ft at 102rpm... Check this baby out here;
