I've driven a few hybrids from Lexus (so 'money-no-object' cars).
And in all honesty, if it weren't for the Americans being so anti-diesel, and the DOT test in this country's basis for a CO2-based VED and company car-tax scheme you would scratch your head trying to find ANY real advantage over a highly-engineered turbodiesel.
Its crazy to see diesels delivering 100 BHP/litre (once the measure of a racing engine), whilst giving real-world economy which no hybrid can deliver. Yet, because the hybrid performs better on the government test, it is designed to flatter - it's the hybrid which gets the benefits, despite being heavier, slower, thirstier, having less space and being much more complicated...
Colin Chapman said, 'simplify, then add lightness', but there is little long-term profit in doing that, so manufacturers devise ever-more complicated bolt-on solutions (
's, DPF's, electric power steering, etc), simply to meet targets, which could be achieved through efficiency gains.
'Being Green' is a phrase with more than one meaning.
