Pac-Car II

Pac-Car II was developed as a student project at ETH Zürich (Swiss Federal Institute of Technology). Based on a group of students and an experienced team leader, 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.

Features[edit]

  • Excellent aerodynamics (drag coefficient of Cd=0.075, Af=0.254 m²)
  • an extremely lightweight construction of the body (total mass of 29 kg, carbon fibre materials)
  • low rolling resistance of Michelin's Radial Tyres (Cr=0.0008)
  • highly efficient powertrain (almost 50%)
  • use of simulation and optimization tools (CFD, FEM, MATLAB and Simulink, GESOP)

World Record[edit]

In 2005 on June 26, PAC-Car II set a new world record[1] in fuel-economy of 5385 km/l gasoline equivalence during the Shell Eco-Marathon in Ladoux, France. During its third race over 20.6 km the car consumed approximately 1 g of Hydrogen driving at an average speed of 30 km/h (roughly 18.6 mph). This corresponds to 0.0186 L/100 km (15,200 mpg-imp; 12,600 mpg-US) gasoline equivalence. This world record is certified by the Guinness Book of World Records.[2]
