BOTTROP, Germany — German tuner Brabus may be known for maximizing horsepower on traditional gas- and diesel-powered cars, but notice the lightning-bolt-festooned logo of its new Zero Emission division. The first project out of the division is a customization project off the electric Tesla Roadster that will be on display at the 2008 Essen Tuner Show in Germany.Brabus says the first priority was 'a more exciting sound' for the currently quiet electric sports car. Several simulated engine sounds can be selected by the driver using Brabus' 'space sound generator,' which rises and falls in volume depending on how much power the electric motor is putting out at a given time. Choices: racing engine, 'typical' V8 internal-combustion engine, or Beam or Warp sounds, which Brabus calls 'futuristic soundscapes' but doesn't describe further. Chances are, the average video game user will find those two soundtracks familiar.Naturally, the Tesla Roadster also gets cosmetic modifications. In front, the tuner has added a carbon-fiber lip and daytime running lamps in the grille. These and the rear lamps have matte white surrounds. On the side, 'futuristic space lights' are turned on by pulling the door handle or using the keyless fob; there are also carbon fiber air inlets. In back, there's more carbon fiber in the form of a rear wing and rear diffuser.Inside, the Brabus logo is found on scuff plates and upholstery, and the floor is upholstered with leather.Brabus Monoblock S light alloy wheels, 18 inches in front and 19 inches in back, paired with Pirelli P Zero Nero high-performance tires, and a matte white paint color complete the conversion. Inside Line says: For the electric-car driver absolutely determined to prove that he is not a tree-hugging wimp. — Laura Sky Brown, Correspondent
