"As German automakers such as BMW and Mercedes-Benz update their lineups, the tuning industry quickly follows with even wilder variations of these already impressive performance machines. The BMW 650i Convertible is barely out of the starting blocks, but Lumma Design has already come up with a more powerful version in time for this year&amp;#039;s Geneva Auto Show. Called the CLR 600 GT, this drop-top offers a boost in horsepower and a distinctive new look that (thankfully) doesn&amp;#039;t stray far from the crisp lines of the new 6-Series.        Lumma Design CLR 600 GT    Subtle Upgrades   The CLR&amp;#039;s bright white paint might not be to everyone&amp;#039;s taste, though Lumma has wisely avoided tacking on enormous wings and fender flares. Those design elements are certain to make an appearance in Geneva, just not on this tuned BMW. A new front spoiler has integrated LED daytime driving lights, while revised sills and a rear diffuser add a touch of aggression that isn&amp;#039;t too over the top. A set of GTB-Monoblock 20-in. alloy wheels fills out the wheel wells nicely, and the cabin has been trimmed in white leather to match the paint.        Lumma Design CLR 600 GT    The twin-turbo 4.4-liter V-8 now produces 490 bhp in CLR 600 GT spec. A modified ECU helps give the 6 Series more kick, while a new muffler and quad exhausts should add a nice snarl when you punch the gas pedal.
