Edit: BMW E92 M3 GT4
On 10 April 2009, the week after the debut of the GT4, BMW's Customer Racing program announced it had partnered with Schubert Motorsport (sponsored by Motorsport Arena Oschersleben) to run the BMW M3 GT4 in the 2009 24 Hours Nürburgring race, in the new class for GT4 cars, listed as SP10 there.
The BMW M3 GT4 also raced in the Nürburgring VLN ADAC Westfalenfahrt in April 2009, taking the win in the SP10 class and finishing 30th overall. The 2009 24h race took place on the weekend of 23 and 24 May, with Jörg Müller, Andy Priaulx and sport auto journalist Jochen Übler at the wheel. Despite qualifying as best SP10/GT4 car at 57th overall and being at least 10 seconds per lap faster, the team finished third in the class, behind two Aston Martin V8 Vantage N24. The overall rank was 47th.
BMW Motorsport announced on 7 July 2009 the launch of a line of BMW M3 race cars which meet the SRO/FIA's GT4 spec and are oriented for sale to private teams and drivers. The BMW M3 GT4 price is 121,500 EUR without VAT.
While BMW states that 'the BMW M3 GT4 weighs just 1,430 kilograms' and the '420 bhp engine remained largely untouched', the 2010 24 Hours Nürburgring "Balance of Performance" requires that the power must not exceed 390 PS, while the minimum weight is set to 1400 kg.
The M3 GT4 is offered in Europe as a homologated production race car for sale to the general public. According to Larry Koch, then BMW NA M-brand manager, a feasibility study is currently being conducted to evaluate the possible sale of the M3 GT4 in North America. However, without a sanctioned GT4-class racing series in the USA, the sale of the M3 GT4 in the States is not likely.
