The new engine gave the M3 GTR GT a competitive edge over the Porsche 911 GT3-R and allowed it to win seven out of the ten events in the GT category for the 2001 season. The old engine was ditched as BMW's engineers couldn't squeeze any more horsepower out of it. It was developed alongside the BMW V10 engine that was used to power Williams Formula 1 cars during the 2001 F1 season. The car first entered the GT class of the American Le Mans Series in 2000, in which it only took a single victory and was beaten on several occasions by the Porsche 911 GT3-R.Ī newly developed P60B40 V8 engine was quickly placed into the race car before the beginning of the racing 2001 season. It was originally fitted with a 3.2L inline-six engine based on the engine of the standard E46 M3. It competed during the 2001 racing season under both the BMW Motorsport and Team Schnitzer teams, with the car being entered in the GT class of The American Le Mans Championship and the European Le Mans Series. The 2001 BMW M3 GTR GT (E46) is a race car developed by BMW based on their M3 E46. Front-Engine, Rear-wheel drive For the homologation road car, see BMW M3 GTR (E46) For the road car, see BMW M3 (E46)
