Historically, many records are set in the high-speed circuit. Each year in southern Italy, in collaboration with the AUTO BILD sportscars’ editors and under the aegis of Continental AG, the top vehicle tuners compete. This year, it was on Oct. 18-19, 2009. The record for the fastest road-legal diesel car was broken by the AC Schnitzer ACS3 3.5d Coupe with a speed of more than 8.7 km/h.288.7 km/h.
This was the figure on the display of the GPS speedometer system on the 13 km long high-speed circuit after the lap of the AC Schnitzer ACS3 3.5d Coupé. The record that was broken had been that of 2006 with the TENSION as the fastest road-legal BMW. The record had held in 2007 when the GP3.10 GAS POWERED entered to represent gas-powered vehicles. AC Schnitzer cited its power upgrade as the reason for its success.
Naturally the power upgrade which took the latest world record holder to success is part of the extensive AC Schnitzer special accessory range and available for all vehicles based on the 3.5d engine. It is TÜV-approved and available from BMW dealers.
Another impressive performance in Nardò came from the AC Schnitzer ACS4 3.5 turbo (based on the BMW Z4 sdrive 35i). At 303.1 km/h, this was not a new world, but such a high speed is almost unheard of for a Roadster. The Z4 was also running with the commercial version of the AC Schnitzer performance upgrade for 3.5i engines.
