But that probably has more to do with alternators replacing dynamos than the batteries themselves.

Fiat 500 Coupe Zagato gets green light

Fiat 500 Coupe Zagato to go in to production When we counted up the number of cars that appeared at the Geneva Motor Show this year it came to over 200. Not all the cars were new arrivals and many were a bit dull.

VW Golf GTI Edition 35 hits showrooms

VW Golf GTI Edition 35 We’ve had lots of motoring anniversaries this year, from the 50th of the iconic E-Type to the centenary of the Indianapolis 500.

The original Golf GTI was a revelation; light, nimble, fun and fast it was an instant hit – the first of the proper hot-hatches.
