2011 Citroen C4 e-Hdi

2011 Citroen C4 will be available Citroen's new micro-hybrid powertrains e-Hdi. The C4 is powered by a 110bhp 1.6-litre turbodiesel engine mated to what Citroen (and many rivals) call a micro-hybrid system. That's slightly misleading as it's not a hybrid in a conventional sense; instead it's a generator-starter motor. That gives the e-HDi micro-hybrid stop-start capability, helping reduce its emissions and improve fuel economy.

Citroen is making a big deal of the C4 e-HDi's 109g/km CO2 emissions and 64.2mpg economy, but among its green rivals that's only average performance. Citroen has a 99g/km C4 in the pipeline, but the e-HDi is already playing catch up with established rivals, despite being an all-new proposition.

Citroen C4 e-Hdi exhibits a new level of interior quality from the French firm. There are lots of buttons around the cabin, but the overall look is one of decent quality. The EGS clutch-less transmission is standard in this e-HDi model, meaning a raised centre console with a cool looking lever for gear selection - incorporated neatly. Space is good too, with leg- and headroom generous for four adults, while a large boot means there's plenty of luggage space, too.
