The yellow boxfish, Ostracion cubicus

The Mercedes-Benz Bionic was a concept car created by DaimlerChrysler AG under the Mercedes Group. It was first introduced in 2005 at the DaimlerChrysler Innovation Symposium in Washington, D. C. The Bionic was modeled after a type of fish, the yellow boxfish, Ostracion cubicus,[1] and also has 80% lower nitrogen oxide emissions with its selective catalytic reduction technology.

Engine and performance

The Bionic is powered by a 103 kW direct-injection diesel engine that gives out around 70 MPG (US) (~3.36 L/100 km). This engine also gives out around a total of 140 hp (104 kW) and a little over 221 ft⋅lbf (300 N⋅m) of torque at around 1600 rpm. The Bionic can go from 0–60 mph (97 km/h) in about 8 seconds and has a top speed of a little over 190 km/h (118 mph) .

Design

The exterior design was modeled after the yellow boxfish (Ostracion cubicus), a marine fish that lives in coral reefs. Mercedes-Benz decided to model the Bionic after this fish due to the supposed low coefficient of drag of its body shape and the rigidity of its exoskeleton; this influenced the car's unusual looks. Other parts of the design include the fact that the rear wheels are partially fitted with plastic and that it's considered as a lightweight vehicle. Mercedes-Benz reported a drag coefficient of 0.19;[2] for comparison, the production vehicle with the lowest ever Cd value was the GM EV1, at 0.195. While the Bionic had a much larger internal volume than the EV1, the Bionic's larger frontal area made the EV1 more aerodynamic overall, as drag is a product of the area and the drag coefficient.
