Grumpy chats about hybrid cars

22 October, 2012 by Mike Smyth, specialist technical writer

I don’t know about you but I am mightily underwhelmed by hybrid cars. True, they are full of sophisticated electronics and true they do go some way towards satisfying the consciences of greenies. But, on the down side, they are expensive, they are complex, they have limited range in their electrical mode and there are few places to charge the batteries other than in your own garage. To me they are bisexual products of a motor industry that has reluctantly pandered to ill-conceived demands from governments intent on being seen to be saving the planet.
