The Berlingo Efficient-C's 92 bhp 1.6-liter turbodiesel and electric motor achieve a combined 75 mpg as well as a 30 percent improvement in CO2 emissions over a comparable diesel-only drive train as it emits just 99 g/km. In comparison, Toyota's Prius spews 104 g/km of CO2.
Auto Express predicts that Europeans should see the drive train hit the market in the next-generation C4 in 2010. As for the infamous dual-impact premium that has driven other automakers away from developing the concept, Citroen estimates that the Efficient-C adds £3,000 to the price of a standard Berlingo, but hopes that by the time it's ready for release the cost of the technology will wither to about 50 percent of that.
