V8-powered PTG BMW M3 E46 GT Grand-Am racing at Mugello + OnBoard & HQ Audio!

This E46 was the car that nearly gave me a heart attack when I saw it during the Mugello Classic racing weekend by ‪@peterautoracing‬ last year. I was really shocked by the thought of finally finding myself in front a genuine E46 GTR with the 4.0L V8 but within seconds I realized I may never get any closer to record the actual unicorn in my life (yes, you are right.. never say never in life!). However the history of this M3 is linked to the 2001 ALMS Porsche-killer. In 2000 BMW North America turned to Tom Milner's Prototype Technology Group (PTG) to transform the new M3 E46 into a Grand-Am Series weapon. This championship was a North American-based sports car series founded in 2000 under the name Grand American Road Racing Championship, which replaced the failed United States Road Racing Championship. The new series would run two classes of Sports Racing Prototypes identical to the rules used by the FIA in Europe, while Grand Touring-style cars would consist of three classes: GTO for larger production-based race cars, GTU for smaller production-based race cars, and AGT for American tube frame cars. GTO and GTU would be renamed GTS and GT for 2001 to better match the classes used by the similar American Le Mans Series. Five years prior, PTG already worked on a BMW car, the E36, from which a pole sitter for its GTS-2 debut was born. With that experience, PTG was granted to work on the new E46. At first only three chassis were built and fielded in the 2000 season. These cars had their chassis reinforced and dressed by a bespoke carbon-fibre composite bodywork, plus a dry-sump version of the S54B32 straight-6 engine was fitted. These cars were both entered in the Grand-Am and the American Le Mans Series, in which it scored a class win during the Laguna Seca round. It was a rare highlight in a season dominated by the Porsche 911 GT3. In the meantime PTG was already thinking on how to improve its creature as the straight-6 used in the M3 road car wouldn't provide a suitable basis for a competitive racing engine. The same thought afflicted the German brand that wanted to aim big in the GT-class of the ALMS and cease Porsche's dominance. But this is another story (Yes, that story...). So PTG studied the Grand-Am rulebook carefully and found that GT-class race cars could use any engine from an automaker's portfolio. For 2001 two new E46s chassis were fitted with the S62 engine, a 4.9-liter V8 taken from the M5 E39 which was still on the market at the time. This V8 was a gem of an engine, with more power than the six, a lower center of gravity, and essentially the same weight. PTG did most of the competition modifications to the S62 in house, although BMW Motorsport supplied racing camshafts and a VANOS variable valve timing system delete. It was linked to a Hewland six-speed manual transmission. The PTG M3 V8 (chassis 004, the one you see in this video) debuted in early February 2001 at the 24 Hours of Daytona, a month ahead of the 4.0-liter M3 GTR in the ALMS, making it the first V8-powered M3 to race in North America. Chassis 004 was fielded under the Bell Motorsports banner and driven by Terry Borcheller, Toney Jennings, Boris Said and Hans Stuck. Even though mechanical troubles sidelined the M3 with six hours to go, PTG’s car dominant pace in both qualifying and the race had the governing body worried, leading to the decision of add a 45kg (100-lb) weight penalty to the car and air restrictors that sapped about 90 hp. Those penalties hardly slowed Borcheller and Jennings down as they racked up GT-class wins at Homestead, Lime Rock, and Mid-Ohio. The car continued to be fielded in various races in both 2002 and 2003. By 2012 this M3 GT found itself back at PTG, where it was the last car Milner’s racing team refreshed before closing their doors in 2013. It was restored to its 24 Hours of Daytona debut in 2001. Watch and hear it in action on the Italian track, being raced in the Endurance Racing Legends series! #BMWM3E46 #M3E46V8 #BMWS62 -------------------------------------------------------------- I have to thank my friends and youtubers ‪@Italiansupercarvideo‬ and ‪@NM2255‬ for the great collaboration done.
