Flex-fuel engines in all Bentley models by 2012
4 March 2008

Bentley will reduce emissions across its entire range to just 120g/km of C02 by 2012, it announced today. The company will achieve this target by creating lighter cars and introducing improved transmissions and enhanced engine management and on both the V8 and V12 units. Bentley CEO Franz-Josef Paefgen said: "We will set a benchmark in our segment by making every engine capable of running on renewable fuels."The new flex-fuel powertrain is already under development and is planned for introduction in 2012. It should deliver a 40 per cent reduction in fuel use without compromising performance and refinement. Paefgen finished on an optimistic forecast for the company's new eco-plan: "It is our conviction that renewable fuels have strong potential. Taken together, the measures we are announcing will make the entire Bentley fleet capable of delivering less than 120g/km by 2012."

Surely it's the start of March, not April? 120g/km in a Bentley; I can't even begin imagine the work this will take but fair play if it is achievable.

Oh dear, Bentleys ruined, they'll never get there!

If they can do it, doesn't it sort of indicate that those manufacturers hitting the better CO2 figures now - around 100-140g/km - could cut them by two thirds as well? Or is my lack of engineering knowledge tripping me up?

By which time Livingston will have probably lowered the C02 threshold incurring the £25 charge (except that it have risen to £100 by then) down to 100g/km.

Boy oh boy! Talk about lost in translation! What you have said is not correct. I've just read a German web site's report of Paefgen's Geneva announcement for clarification. As follows:

The 120g CO2/km figure is for "well-to-wheel", not consumption. Hence the incomprehension of the commentors so far.

Further, what Paefgen actually announced was:

intention to reduce average consumption by 15% by 2012;

all engines to be 'Flexi-Fuel' by 2012;

introduction of a new powertrain, which will permit reduction in consumption of 40% by 2012 - not stated but expected to be a hybrid powerplant;

by use of E85 biofuel will the emission level be reduced to under 120g CO2/km as measured by the so-called "well-to-wheel" method. This measure-cycle considers all steps in the production of the fuelstuff through to consumption.

For a full report, in German, of the above see the link below:

I have to add that the journalist's post here was not researched through.

Is the V12 a new engine!?
