BMW and Mini's market positions as the number one premium cars within their segments in London have been strengthened with the Mayor of London's announcement of a new charging structure for entering the capital in a car. New legislation which comes into effect in October means drivers of vehicles emitting less than 120g/km will be Congestion Charge exempt. Drivers of cars emitting between 120g/km and 225g/km will continue to pay the standard £8 a day fee, while those driving vehicles that record more than 225g/km will pay an increased daily charge of £25. The change in charging structure means BMW and Mini owners will be financially better off than owners of other prestige cars. All Minis and most BMWs will remain within the £8 threshold, but there was further good news for many BMW and Mini owners. The BMW 118d, the Mini Cooper D and the Mini Clubman D all fall into the new sub 120g/km Congestion Charge-free bracket. This means that from October 2008 an owner of one of these models will save £2040 a year driving in the capital compared to owners of non-exempt rival products. The 110hp Mini Cooper D is currently BMW Group's most fuel-efficient car recording 72.4mpg on the combined cycle and CO2 emissions of just 104g/km. The Mini Cooper D Clubman nearly matches these statistics recording 68.9mpg and 109g/km. Both cars are Band B in relation to Vehicle Excise Duty tiers and cost just £35 a year to tax.
