BMW bowled a bouncer in the Frankfurt motor show's war of green words at the first unveiling of the day.
Chairman Dr Norbert Reithofer claimed that the BMW Group, which also includes Mini and Rolls-Royce, is 'the most sustainable car manufacturer in the world' and says that opinion is supported by the latest Dow Jones sustainability index.
'No other manufacturer in our industry uses resources as economically as we do. This inspires us to go even further. We have accomplished a lot but we will do even more,' he added.
Dr Reithofer said there are now 1.4 million BMW Efficient Dynamics cars on the road, and that the group's average fuel economy figure in Germany is now more than 50mpg, even though the range includes big V8 and V12 models.
'Our fleet average fuel consumption is down by more than any other manufacturer,' Dr Reithofer said.
Hybrids close to production
BMW is exhibiting two hybrids at Frankfurt, based on the 7 Series limo and the X6 SUV. Both are scheduled for production 'in the near future' and are said to deliver better performance than corresponding V8-engined models, with 15-20% lower fuel consumption.
The company is also showing a futuristic concept coupe, called Vision Efficient Dynamics, which has a three-cylinder turbodiesel engine and two electric motors that can be used in any combination. It also employs anticipatory energy management to trim fuel consumption.
BMW claims supercar levels of acceleration, but with similar fuel economy and emissions figures to a diesel supermini.
Although the car is unlikely to see the light of day in its entirety, elements of its drive system could do. It also gives pointers to future BMW styling.
