Fuel duels - Hybrid

As used in: Honda Civic Hybrid, Toyota Prius, Lexus RX400h.

What is it? A car with two power sources, usually a petrol engine and an electric motor.

Cost: 87.1p per litre (unleaded).

Where can I buy it? Hybrids use unleaded, so any petrol station.

Pros: Hybrids have better fuel economy and lower emissions than petrol-powered models. There are tax advantages; and they are easy to refuel.

Cons: There are only a limited choice of models – and these are generally pricey. The major fuel economy savings are achieved in town only and hybrids have limited range when only powered by an electric motor.

Expert view: Hybrid cars will be an increasingly attractive alternative to conventional vehicles.

Outlook: They will almost certainly bridge the gap between the current generation of cars and zero-emission vehicles in 10 or so years. Forthcoming diesel hybrids can only enhance their appeal.
