PAC-Car II
Pac Car II is a motor vehicle with fuel cell drive, which has been optimized for low fuel consumption. It was developed by a group of students at the ETH Zurich (Swiss Federal Institute of Technology). The aim of this project was to develop a vehicle that is in operation consumes as little fuel as possible. In realizing this ambitious goal, the students were supported by experienced team leaders from industry and academia. For the provision of power a fuel cell was used, which was developed specifically for this car at the ETH / PSI Paul Scherrer Institute.
Facts
- Minimum amount of air resistance (cw = 0.075, A = 0.254 m2)
- Extreme lightweight construction of the housing ( total weight of 29 kg, carbon fiber)
- Low rolling resistance by special radial tires ( cR = 0.0008 )
- Highly efficient drive unit (efficiency close to 50 %)
- On the track and the vehicle metrics optimized driving strategy.
- Application of modern simulation and optimization programs (CFD, FEA, Matlab / Simulink, GESOP )
World Record
On June 26, 2005 PAC - Car II drove during the Shell Eco- Marathon in Ladoux (France) set a world record in the area of the lowest fuel consumption ( 5385 km / l petrol equivalents, which corresponds approximately to the distance from Gibraltar to North Cape ). During the third race over 20.6 kilometers distance the vehicle consumed only about one gram of hydrogen at an average speed of 30 km / h One gram of hydrogen corresponds to the energy content of 0.00375 liters of petrol ..
This world record is entered in the Guinness Book of Records.
