The Brabus rocketeers say they've broken the speed record for street-legal sedans, having been certified by Germany's technical standards agency, T V, for hitting over 227 mph on the Nardo test track in southern Italy. The ber tuner's ber sedan, the Rocket — based on a Mercedes-Benz CLS — is powered by a bored-out and twin turbo'd V12 displacing 6.3 liters and producing 730 hp and an electronically limited 811 lb-ft of torque (it also meets EURO IV emissions). We'd imagine the record will spark an arms race among German tuning shops who'd rather not let the maniacal laughter from the Bottrop boys go unchallenged.
