Ken Livingstone has confirmed that the London Congestion Charge will in future exempt cars emitting less than 120g/km of C02. Although this is in line with the original thinking for revising the scheme, most recent reports had suggested that the proposed exemption would be dropped because of the large numbers of cars that were expected to sneak in under the limit.
Lots of the car-makers have put out press releases trumpeting which models in their ranges will be exempt. Renault claims that 31 models in its range will be CC free. Apart from Lexus' hybrids, which continue to enjoy the exemption as well, I think the classiest car to slip through is BMW's 118d - not the last word in prestige and luxury, but hardly the sort of hair-shirted economy motor Ken probably had in mind when he first thought of the exemption either.
