Efficient Diesels

What are they? Diesel cars that have been tweaked for fuel efficiency through aerodynamic changes and more frugal engines.

What do they mean to me? Fewer visits to the petrol station and a cut in your fuel bill.

Good if you: Live in the countryside, don't want any compromises

Bad if you: Drive into the Congestion Charging zone, care strongly about local air quality

Models to check out: SEAT's Ibiza Ecomotive are also excellent choices.
