<P> On 31 March 1998 Andy Wallace drove the five - year - old XP5 prototype at Volkswagen's test track in Ehra - Lessien, setting a new production car world record of independently measured 240.1 mph (386.4 km / h) two - way average (peak speed 243 mph (391 km / h) measured by McLaren) with the rev - limiter raised to 8300 rpm . </P> <P> It's said that the certified 240.1 mph were converted from 386.7 km / h which is almost 240.3 mph if converted more precisely, so top speeds in the 240.1--240.3 mph (386.4--386.7 km / h) range can be read from various sources . </P> <P> Depending on the definition of "production car" it was dethroned in November 1998 by the Dauer 962 Le Mans (404.6 km / h (251.4 mph) in Ehra - Lessien) or in April 2007 by the Bugatti Veyron 16.4 (408.47 km / h (253.81 mph) in Ehra - Lessien). </P> <P> Following its initial launch as a road car, motorsports teams convinced McLaren to build racing versions of the F1 to compete in international series . Three different versions of the race car were developed from 1995 to 1997 . </P>
