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 performanceThe Bionic is powered by a 103 kW direct-injection diesel engine with an average fuel economy of 54.7 MPG (US) (~4.3 L/100 km).[2] This engine also outputs around {{convert|140|hp||0|abbr=on}} and a little over {{convert|221|ft·lbf|N.m|abbr=on}} of torque at around 1,600 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 {{convert|190|km/h|mi/h|0|abbr=on}}. DesignThe 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[3] and the rigidity of its exoskeleton; this influenced the car's unusual looks. It was believed that the shape of the boxfish would improve aerodynamics and stability.[4] 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;[5] 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. The vehicle was capable of seating four people.[2] References1. ^{{cite web|title="Bionic" Car Fueled by Fishy Ideas|url=http://news.nationalgeographic.co.uk/news/2005/06/0615_050615_fishcar.html|work=National Geographic|accessdate=18 October 2013|date=15 June 2005|deadurl=yes|archiveurl=https://web.archive.org/web/20131019205924/http://news.nationalgeographic.co.uk/news/2005/06/0615_050615_fishcar.html|archivedate=19 October 2013|df=}} 2. ^1 {{cite web |url=https://www.motor1.com/news/299424/mercedes-bionic-concept-we-forgot/ |title=2005 Mercedes Bionic: Concept We Forgot |last=Padeanu |first=Adrian |work=Motor1.com |date=2 January 2019 |accessdate=22 January 2019}} 3. ^{{cite journal|last1=Kozlov|first1=Andrei|last2=Chowdhury|first2=Harun|last3=Mustary|first3=Israt|last4=Loganathan|first4=Bavin|last5=Alam|first5=Firoz|title=Bio-Inspired Design: Aerodynamics of Boxfish|journal=Procedia Engineering|volume=105|year=2015|pages=323–328|issn=18777058|doi=10.1016/j.proeng.2015.05.007}} 4. ^{{cite magazine |title=The Energy-Efficient Boxfish |journal=Awake! |publisher=Watchtower Bible and Tract Society of New York|date=July 2009 |volume=90 |issue=7 |page=10 |issn=0005-237X |url=https://wol.jw.org/en/wol/d/r1/lp-e/102009248 |accessdate=22 January 2019 |quote=Engineers believe that the boxfish provides the secret to producing a safer, more fuel-efficient, yet lightweight, vehicle. “Quite frankly,” says research and development chief Dr. Thomas Weber, “we were surprised when this clumsy-looking fish, of all things, became our model for designing an aerodynamic and fuel-efficient car.” }} 5. ^Mercedes' fish-inspired car CNN (retrieved 2008-08-12) External links
