We already mentioned PSA's plans to downsize engines
in an effort to improve fuel efficiency
. The French company will showcase the progress its making during PREDIT (National Program for Terrestrial Transport Innovation), which is taking place this week in Paris. PSA will show a prototype co-developed with Valeo and IFP (the teams behind the low-carbon Smart
). The prototype is a Citroën C2 with a two-cylinder engine, 8 valves and a mild-hybrid system with Stop&Start and regenerative braking. This allows the sub-subcompact to use 3.8 l/100 km (62 mpg U. S.) and emit just 90 g/km of CO2
. The "regular" C2 featuring a 1.1 liter I4 engine uses 5.8 l/100 km (40.5 mpg U.S.) and produces 138 g/km of CO2
. The C2 in the gallery below is the sporty version.
