German carmaker DaimlerChrysler will today officially unveil a prototype of a new diesel vehicle that it says will meet more stringent pollution-control requirements and get higher mileage. The concept car uses lighter materials and an aerodynamic design that allows it to get about 70 miles to the gallon. Although the company has not yet decided whether it will mass-produce this prototype, the diesel technology will be incorporated into future models to help meet federal emissions standards that will come into force in 2007.

Interestingly, the inspiration for the design came from the boxfish, a variety of tropical fish, and the result (with its sleek lines and boxy rear) is strikingly similar. Maybe it’s just me, but the boxfish doesn’t look like it’d be particularly speedy. It does, however, make for a very cute car.
