Pac-car

From Wikipedia, the free encyclopedia

Pac-Car II is the world's most fuel-economic vehicle. It was developed as a student project at ETH Zürich (Swiss Federal Institute of Technology). Based on a group of students and an experienced teamleader, the goal was to build a vehicle, that uses as little fuel as possible. By using hydrogen fuel-cell, developed at ETH/PSI (Paul Scherrer Institute), as power source, pure water is the car's only emission. Clean mobility completed therefore the educational and energy saving aspects of the project.

[edit] Facts

Excellent aerodynamics (Cw=0.075, Af=0.254m^2)^{[citation needed]}
an extremely lightweight construction of the body (total mass of 29 kg, carbon fibre materials)
low rolling resistance of Michelin's Radial Tyres^{[citation needed]} (Cr=0.0008)
highly efficient^{[citation needed]} powertrain (almost 50%)
use of latest simulation and optimization tools (CFD, FEM, MATLAB and Simulink,GESOP)

[edit] World Record

In 2005 on June 26, PAC-Car II set a new world record in fuel-economy (5385 km/l gasoline equivalence) during the Shell Eco-Marathon in Ladoux (France). During its third race over 20.6 km the car consumed approx. 1 g of Hydrogen driving at an average speed of 30km/h. This corresponds to 0.0186 l of gasoline equivalence/100km, or 12,645.9454MPG [1]. This world record is certified by the Guinness Book of World Records.
