Since we saw the Chevrolet Volt at last year's Detroit show, GM chiefs have been umming and ahhing over when the electric-petrol hybrid will actually make it to production. But that hasn't stopped them pushing ahead with more hybrid concepts in various shades of green. At Detroit next week we'll see Cadillac's take on GM's E-Flex green propulsion system: the Provoq, a hydrogen fuel-cell crossover concept. The Provoq uses a drivetrain similar to that in the Honda FCX Clarity - a hydrogen fuel cell and lithium-ion battery combining to produce an electrically charged vehicle that emits only water. The fuel cell develops 118bhp of power, boosted by an extra 80bhp of electrical energy from the battery. |
