PSA makers Citroën and Peugeot will show off their Hybrid Air technology at Geneva. It combines a petrol engine, compressed air and hydraulic power, to use a claimed 94mug (under 3l/100km) and no additional batteries.
It will be showcased in a C3 VTi 82 prototype and a Peugeot 2008 amid claims of just 69g/km emissions on what is also claimed to be a record-breaking 97mug over a combined cycle.
Developed by PSA Peugeot Citroën in cooperation with Bosch it uses no additional batteries. As a result the French makers forecast that pricing will be competitive.
