Car Touts Diesel Potential

reveals several unique with a new high-economy concept

WASHINGTON, DC – If there were any left, the diesel-powered “bionic” car unveiled here by DaimlerChrysler Mercedes-Benz unit shows manufacturers think diesels more growth potential in the than hybrid-electric vehicles

Thomas Weber, board responsible for research and development for the Car Group, introduced the vehicle was inspired by the cube-shaped boxfish at recent Innovations Symposium.

Bionic concept car grew

extraordinary fuel economy, space and clean emissions, the car be a template for future vehicles.

says the 4-seat, 2-door minivan, a driveable concept, is by a 2L 4-cyl. turbodiesel that 140 hp and 221 lb.-ft. (300 Nm) of torque 1,600-3,000 rpm.

The diesel is connected to an Autotronic variable transmission (CVT).

The emissions are cleansed by a particulate and a selective catalytic reduction system to process excess of nitrogen (NOx).

The SCR system a precisely measured urea (determined by driving conditions) the exhaust system to allow NOx to be processed into benign and oxygen. The SCR fluid is stored in the wheel recess and requires in a service cycle of about miles (24,139 km). auto makers and suppliers in production or have shown SCR that require almost no maintenance.

DC diesel-powered commercial already are using SCR technology, Weber.

“With the bionic car, we are the potential that SCR has when in passenger cars,” he says. “We are to apply this innovative whenever the prevailing conditions that it will benefit our

He claims NOx emissions can be reduced up to 80% U.S. driving conditions SCR. Mercedes calls its compound AdBlue. When SCR is complete, the technology will be in the U.S. Weber adds.

The car has a top speed of 118 mph (190 km/h) and from 0-60 mph (97 km/h) in a 7.9 seconds.

Its sleek, 0.19 Cd body – inspired by nature’s odd – helps the bionic car achieve 70 mpg (3.4L/100 km), says At a constant 56 mph (90 km/h) fuel is roughly 84 mpg (2.8L/100 km) in the U.S. test cycle.

The excellent fuel economy the bionic car a cruising range of 746 (1,200 km) on its 14.3-gal. (54L) tank.

The direct-injection diesel is designed to run on low-sulfur fuel already is available in Europe and is for U.S. rollout in fall Weber says the bionic car the Euro 4 emission standards.

“We are to the diesel engine – not only in but also here (in the U.S.),” says. He notes that share in the U.S. currently is 4%, but that’s four times the for HEVs.

He forecasts by 2011, will command 10% of the U.S. while HEVs capture a 3% share.

“Both diesels and hybrids be relevant in the U.S.,” he says,

DC engineers first built a whose shape substantially that of the boxfish. Wind tests of that model a Cd of 0.06. Then DC engineers a 1:4 model that had a Cd of 0.095 in a tunnel. These models into the concept unveiled that is 167 ins. (424 cm) and has enough interior space for occupants. The car is 71.7 ins. cm) wide and 62.6 ins. cm) high. Wheelbase is 101.2 (257 cm).

Weber DC engineers used special to create a body structure is both lightweight and rigid, studying the hexagonal, bony that make up the boxfish’s Using a design process by the principles of bone formation, the car’s structure and body have a high strength-to-weight

Body weight was cut by one-third this design, he says, and panels are up to 40% more rigid of this engineering breakthrough.
