Warning to London car buyers

Motorists who plan to drive within London's Congestion Charge zone are being urged to consider their new car purchases carefully in light of the forthcoming 25 fee for high-emitting vehicles.

The new charging scheme comes into force on October 27, with cars that emit more than 225g/km of carbon dioxide being hit with a 25 charge. Cars that emit 120-224g/km will pay 8 and those emitting less than 120g/km will have the fee waived.

However, new car buyers are being urged to check emissions figures carefully before buying to avoid being caught out.

For instance, a BMW X5 3.0sd SE 4x4, a BMW 335d SE and Jaguar XF 2.7D V6 Luxury would only attract the 8 fee.

In contrast, a Ford Galaxy 2.3 Ghia Auto MPV, Honda Accord 2.4 i-VTEC ES Tourer, Peugeot 407 SW 2.7 V6 HDi GT Auto or Vauxhall Zafira 2.0i 16v T Design MPV will all pay 25.

Whatcar.com lists all emissions figures in the 'Running Costs' section of each car review.
