the car that did the record was not a Longtail ... it was the final McLaren F1 prototype called XP5 ... the green one … the removed the rev limiter which was 7500rpm ... it achieved the 240mph at 7800 rpm ... and the tiers were Michelin not Goodyear
Andy Wallace (racer) piloted it down the 9 km straight at Volkswagen’s Ehra test track in Wolfsburg, Germany
here are the pix of the car




I know that, you might have meant confused--i meant thast the book goes from start to finish, finish being the 240.1 mph that XP5 did that I mentioned.
hey guys, great thread
I am going to take the conversion to the poor man's level 
1. Why did Toyota stop producing the Supra? growing up I loved seeing that car on the streets.2. What ever happened to the Acura NSX? too pricey and too under powered?
3. In NY the BMW M5 are becoming a dime a dozen, I still want one 
It got too big, too heavy, and and too expensive...with only 320 HP. Plus the Inline 6 wasn't going, nor did it meet the strigent emissions tests that Japan had. They had to recert the engine to put in my IS300 (2JZ-GE). That's why Toyota (lexus) went with a V6 with the next gen Lexus IS.
As far as the Next M5, chances are it will have the Twin Turbo V8 that's found in the new X6 M and X5 M--producing 555 HP in those, it maybe 575 in the M5.
