Hamann has developed a new DTM-style wide-body kit to enhance the sports sedan’s aerodynamics — and, some might argue, its curb appeal. Widened fenders make room for the massive 21×9.5-inch front and 21×12-inch rear wheels. A new front apron (with integrated LED running lights), side skirts, and rear apron redirect airflow around the car. The roof- and truck-mounted spoilers combine for increased down force, Hamann claims. Carbon-fiber exterior trim is also available.
Inside, Hamann replaces the stock leather with higher-quality hides. Aluminum pedals are part of the Hamann M5 package, while buyers can specify piano black, leather, or Alcantara trim.
Hamann is developing exhaust and engine management upgrades for the BMW M5’s twin-turbo 4.4-liter V-8 that’s already good for 560 hp and 500 lb-ft of torque. The tuner expects power increases of 158 hp and 162 lb-ft torque for a total of 718 hp and 662 lb-ft of torque to abuse the wider tires.
