BMW champion team PTG closes

The Prototype Technology Group team that masterminded BMW's sportscar successes with the M3 in North America in the 1990s and 2000s is closing its doors. Tom Milner's Virginia-based PTG squad was appointed by BMW North America to mastermind its entry into the IMSA series with the E36-shape M3 in 1995. The partnership yielded titles in IMSA, the United States Road Racing Club championship, the American Le Mans Series and Grand-Am across 11 seasons and two generations of M3
