The new M273 engine, featured on the current Mercede-Benz 500/550 range, packs quite a punch. But the Denmark based "tuner" Kleemann wanted more of a Mohammed Ali KO whallop, and developed a compressor system and introduces their own EMS. Boost pressure ranges between 0,3 and 0,7 bar to ensure optimised power throughout the rev range, and together with their low rpm torque (90% 0f 660 Nm is available at 2000rpm) this tune-up will really get your Benz flying.
