BMW M3 GTR Strassenversion with a P60 V8

In 2001 BMW Motorsport developed the V8-powered BMW E46 M3 GTR race car to compete in the American Le Mans Series (ALMS). The ALMS homologation rules required BMW to produce at least 10 street-legal cars. There is disagreement about how many BMW E46 M3 GTR Strassenversion (Street Version) were produced. BMW M states 10 were produced. However BMW press states only six were produced; three being engineering-development models eventually recycled and three production-level models surviving in the BMW Group Classic collection. BMW created the E46 M3 GTR Strassenversion with a naturally aspirated 4.0 L P60B40 V8 featuring a 90-degree block, flat-plane crankshaft, forged internals, and dry sump. The P60 V8 in the GTR Strassenversion was similar to the race motor however it was detuned. There is no consensus on output numbers but different BMW sites state between 350-380 hp (257-279 kW) and 365 Nm (269 lb-ft) of torque. They paired the V8 to a six-speed manual transmission with a twin-plate clutch and limited-slip differential. The GTR Strassenversion also features a straightened chassis with a sport suspension based on the race car’s suspension. The body used carbon fiber on the roof, front and rear bumpers, and rear wing. It rode on 19×8-inch wheels with 225/40 tires in front and 19×9.5-inch wheels with 255/35 tires in back. The GTR Strassenversion did not have air conditioning, radio, or rear seats.
