Carfax Certified !! Rare M Roadster !! Only 84K Miles !! The rush of 315 horses twisting their way through five short gears (at the beckoning of an exquisite shifter, we add) with only 3141 pounds' worth of momentum resistance makes for quite modern acceleration indeed--the quarter-mile flashes by in just 13.1 seconds at 109 mph. (That qualifies as third best in this test, but only by an eyelash.)This marvelous M engine whips up 1.6 horsepower per cubic inch--an impressive figure for a naturally aspirated engine. The intake system is fully machined for optimal flow, and the pistons compress the combustibles at a lofty 11.5:1 ratio (highest in any BMW street-car engine). Direct-acting finger followers help lighten the valvetrain by 30 percent, permitting a higher (7600 rpm) maximum engine speed, and the VANOS system varies the intake- and exhaust-valve timing by up to 60 and 46 degrees, respectively (well up from 40 and 25 degrees in the Z3 3.0). The combined effect feels just like more cubes or a supercharger, but in our foot-to-floorboard test, flogging four cars of similar weight equally hard, BMW's high-tech approach yielded the best trip fuel economy (20 mpg) Visit Ormond Fine Autos online at www.ormondfineimports.com to see more pictures of this vehicle or call us at 855-209-7753 today to schedule your test drive.Monday through Friday, 9.am to 5.pm.
