CREWE'S Bentley Motors has unveiled a far-reaching environmental strategy to reduce CO2 emissions and improve fuel economy.

The Pym's Lane firm will become the first manufacturer in its segment and one of the first in the world to deliver renewable-fuel vehicles throughout its range.

The strategy follows years of engineering studies and intensive product development, exploring alternative environmental technologies.

Company chief executive Franz-Josef Paefgen said: "This is a major step in the history of Bentley, reflecting the increasing expectation from our customers around the world for performance motoring with fuel efficient engines.

"We will set a benchmark in our segment of the industry by making every engine capable of running on renewable fuels, reducing emissions and improving fuel efficiency throughout our fleet."

Dr Paefgen said the initiative will help Bentley address the two-fold global issue of CO2 emissions and longer-term fuel availability.

He added: "Bentley does not believe that short-term measures are an appropriate answer to these global issues, and is basing its strategy on a long-term vision."

Efficiency improvements will be achieved first through the application of innovative technology to its 8 and 12 cylinder engines, including enhanced engine management, and new, improved transmissions and drivelines.

As part of its commitment to reduce CO2 output on every new model, these efforts will lead to at least a 15% reduction by 2012.

A new powertrain will be introduced by 2012, delivering a 40% reduction in fuel consumption, while maintaining current levels of performance.

And all engines across the range will become compatible with the use of renewable fuels by 2012, with the initial rollout beginning by next year.

Dr Paefgen said: "It is our conviction that renewable fuels, in particular second-generation biofuels, have strong potential.

"On a well-to-wheel basis, such fuels can deliver a consistently high net CO2 reduction of up to 90%.

"By preparing our engines at an early stage for these fuels, we believe we will help accelerate their adoption, as the supply and market for them develop."
