Issue 32 of Science@ifpen - Powertrain and Vehicles

Powertrain and Vehicles: the transportation sector is evolving all the time and profound changes are yet to come. A major challenge for future mobility, vehicle’s electrification will be accompanied by radical technological and software advances, with the increasing development of connected and driverless vehicles, incorporating, in particular, the principles of responsible eco-driving...
