The Shell Project M car is the result of a technology partnership between Gordon Murray Design, Shell Lubricants and engine specialists Geo Technology. Over the past few years, the trio has co-engineered the car's body, engine and lubricants to minimise fuel use and CO2 emissions. It is hoped that by achieving a three-digit mpg number will inspire fresh thinking about personal mobility while minimising energy using existing technologies and materials. The space-age car recently showcased is a reengineered version of Gordon Murray's T25 city car, produced in 2010. To learn more about Project M and its potential, just-auto were among the first group to drive it.
