"  How good is the new ? Is it the beater they claim? Can the 556-horsepower supercharged small-block V-8 of this second generation really match the stunning power and precision of a fourth generation M5 with its magnificent 500-horsepower V-10?   It&amp;#039;s going to take more than blustery speech and a N\u00FCrburgring&amp;#039;s lap time to prove its performance. Instead of waiting a year to do a comparison test, we egged and into an early time-attack duel.   Cadillac is the hungry challenger, making no secret that it has benchmarked the M5 in producing its new 556-bhp , right down to specifying the same Michelin PS2   To keep things fair we arranged the use of a track that wasn&amp;#039;t even finished being built yet and thus one that wouldn&amp;#039;t give \u2014 driver or car \u2014 an advantage. The Monticello Motor Club in New York was still laying sod and installing the front gate when we showed up. This glorious track is long and fast\u2014a perfect venue for testing these ultra sedans.   Cadillac brought hot-shoe John Heinricy while BMW tapped Bill Auberlen. To see what&amp;#039;s-what, each car was outfitted with a full barrage of test gear and then the drivers were let loose. Is there a winner, YEP, but you&amp;#039;ll have to check back on August 25th to find out if the BMW M5 has retained its crown, or not! "^^<http://www.w3.org/2001/XMLSchema#string>
