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 £2,040 a year driving in the capital compared to owners of non-exempt rival products.

Four of BMW Group’s most fuel efficient production cars of modern times have set a new benchmark courtesy of advanced engineering. The three- and five-door BMW 118d now record an impressive 62.8mpg on the combined cycle with CO₂ emissions of 119g/km – putting it into the Band B category for Vehicle Excise Duty. The BMW 118d now costs just £35 a year to tax.

The 110hp MINI Cooper D and MINI Cooper D Clubman both better these impressive figures. The 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.

All four vehicles employ technologies such as Brake Energy Regeneration, Auto Start-Stop and Electric Power Steering under the EfficientDynamics banner to help cut fuel bills and emissions. An optimum gearshift change indicator is included to encourage economical motoring. These innovations are in addition to high-precision direct injection engines on some models that further aid engine performance.

Diesel-powered BMW X5 and X6 owners celebrate and save £4,335 a year
The BMW X5 3.0d and 3.0sd are now the only conventionally-powered vehicles in the segment with automatic transmissions as standard with CO₂ emission figures that fall below the 225g/km band for Congestion Charging.  The X5 3.0d has a CO₂ emission figure of 214g/km, while the sportier twin-turbo X5 3.0sd posts a 216g/km figure.

The introduction of new legislation means the owner of a new diesel-powered X5 will save £4,335 a year in Congestion Charge fees compared with rival, non-hybrid Sports Activity and Sports Utility Vehicles. The low emissions rating for the X5 3.0d and 3.0sd also qualify it for Band F instead of Band G Vehicle Excise Duty, saving owners a further £95 a year. This benefit is set to increase to £190 a year from 1 April 2008 when the VED charge for Band G cars increases. The cost savings for X5 owners are considerable as diesel-powered models account for 95 per cent of annual UK sales.

The BMW X6, the world’s first Sports Activity Coupé, is another model from the BMW line-up to slip under the 225g/km threshold for Emissions Related Congestion Charging in London. The BMW X6 xDrive30d and the X6 XDrive35d have CO₂ emissions figures of 217g/km and 220g/km respectively. Despite boasting rakish looks and on-paper specification and handling akin to a sports car, BMW’s EfficientDynamics technology ensures that these exciting high-performance diesels remain in the £8-a-day charging tier.

Cleaner than a London black cab
By comparison the latest diesel-powered BMW X5s emit less CO₂ than the Mayor of London’s preferred means of transport, the black cab. While the X5 3.0d and X5 3.0sd emit 214g/km and 216g/km respectively, the very latest LTI Vehicles TX4 2.5 produces 233g/km. By contrast the biggest selling BMW X3, the 2.0d automatic, produces just 178g/km.

It’s a similar story with regard to fuel consumption. On the combined cycle the X5 3.0d achieves 34.9mpg compared to a black cab’s 32mpg. The X3 2.0d trumps this by recording 42.2mpg. The X5 covers 9% more miles per gallon and emits 8.2% less CO₂ than the black cab while the X3 covers 32% more miles per gallon and emits 23.6% less CO₂. The average owner of a BMW X5 will do less than 10,000 miles a year, while the average London black cab will cover considerably more.
