Generally a positive review, but it seems the What Car reviewer has misunderstood the engineering by referring to a gearbox. As I understand it engine revs may vary when the engine is acting as a generator, as the power required varies, but at high speeds with direct engine drive to the wheels, the revs will be directly proportional to the speed. The rough fuel consumption estimate of over 60 mpg is encouraging - reviewers are usually rather heavy-footed! And where do they find a starting price of £14800?
