Product Information RD Sport Motor Tunning R54 Step 1A BMW 645Ci 03+ True to its tradition, once again Racing Dynamics discounts the easier forced-induction route and pushes the envelope of its normally aspirated V8 motors to a new level. The R54 uses much of the same technology found in the latest F1 motors; billet crankshaft, billet rods, and a set of forget pistons that are amongst the lightest to ever find their way into a production-based motor. The ported cylinder heads boast 22% more efficiency than the stock ones, and this is mainly obtained through the use of larger valves and modified cam profiles. The motor internals are complemented by a full race-bred exhaust, entirely hand-made out of 304 stainless steel, that features equal lenght primaries, metal matrix catalytic converters, an X-Flow downpipe, and 2 hyper-efficient rear silencers with quad pipes. The result are impressive; 496HP @ 7300 rpm, but more important, an astounding 554 Nm (409 lb/ft) of torque at only 3800 rpm. The performance of the R54 Sport Coupe is exhilarating; 0-100 Km/h (0-60 mph) in a mere 4.5 seconds, and a top speed of 322 Km/h (200 mph). Racing Dynamics is the trademark of Racing Dynamics S.p.A., an Italian tuning company specializing in BMW Group motorcars.

Starting in 2003, following a trademark issue with the former U.S. importer, Racing Dynamics S.p.A. began selling its products in the U.S. and Canada (only) under the RDSport brand name.
