Bentley bosses have dashed hopes of using diesels in future models

Hopes that a big diesel will appear under the bonnet of a production Bentley are likely to be dashed, according to company bosses.

Chairman and CEO Franz-Josef Paefgen admitted some time ago that Bentley had experimented with diesels and found them impressive, but adverse market conditions make the move unlikely, the company now says.

“The forthcoming Euro 6 clean-air regs are likely to pile some big costs on to diesels,” says Bentley powertrain boss Brian Gush.

“And there’s a strong prejudice against them in the US and Japan, which are key markets for us. The attitude of Chinese buyers is going to have a big effect on cars like ours in future, too, and they are none too keen.

“Those of us who know diesels can see the benefits, but in large parts of the world the cars just wouldn’t sell."

The new for 2011 Bentley Continental GT will have a choice of either Bentley’s familiar twin-turbo 6.0-litre W12 with a few minor tweaks or an all-new V8.

The 6.0-litre W12 will have changes made to its engine management electronics and some new low-friction measures that together boost both power and torque, from 552bhp to 567bhp and from 479lb ft to 516lb ft.Bentley isn’t saying much about its all-new V8 except that the capacity is 4.0 litres.

It is highly likely to be turbocharged and it’ll come a year after the new Conti’s launch next March. The V8 version will still have four-wheel drive, engineers say.

In Other Breaking news... The sun will rise tomorrow and other reports suggest that the sea is blue.

Even I wouldn't want a diesel Bentley, and I'm not Chinese or American etc. Diesel in a Bentley would be just wrong.

[quote Dan McNeil v2]Isn't that what people said about Porsche?[/quote] If Bentley made a 4x4 then they should stick a diesel lump in it, however I think a 911 2.0 tdi would be a real shame, though it would sell if they priced it cheaply enough.

Bentley makes lots of 4x4s, many thousands of them every year....

I expect that if Bentley put their owners 4.2 V8 diesel, with its 590 ft/lbs of torque greater than the W12 petrol, in the Continental it would give them new customers in Europe who presently would not consider a Bentley due to running costs of the petrol. As to those who squeal that they would never buy a diesel luxury car just look at the sales figures of Jaguars, Mercedes and BMW diesel range compared to the petrol versions. Just because someone has the desire to spend over £100k on a new car it does not mean that they are willing to give a fortune in fuel tax to the governments of Europe.

It's interesting what Bentley have said about the cost of Euro 6 for diesels. I wonder exactly how much Euro 6 compliance will cost. Is it a case of being uneconomical due to low sales volumes and uneconomical due to difficultly of diesels meeting these standards?

How might this affect the ubiquitous 2.0 diesel engines that sell by the bucket load in your average family car?

I don't think it's a snobbery thing, just a practical one. They can't use the 4.2tdi because it would be slower in the Bentley than in the A8, which would be embarrassing. 0-60 would be about 6 seconds. They'd have to use the 6 litre V12 tdi, and the production numbers just don't justify it.

[/quote] From what I read on the internet the Euro 5 emissions regs allow petrol cars to produce twice the limit allowed for diesels of CO (carbon monoxide). For direct injection lean burn petrol cars the limit on particulates is the same as diesels. Diesels are allowed to produce more NOx under Euro 5 than petrol but for Euro 6 NOx has to be cut sharply. I believe that it is about four years before Euro 6 comes into force and although there are several ways of reducing NOx from diesel cars I have yet to see any manufacturer publish details or the added cost. I did see in an article in Autocar on the Mazda 2.2 diesel that it would have a 14 to 1 compression ratio ( almost petrol levels ) and would probably meet Euro 6. It is interesting that petrol and diesel engines are seemingly merging: compression ratios, lean burn direct injection, turbo charged, with similar particulate limits. Will we end up with a duel fuel engined cars, diesel or petrol by choice?

No blue sky thinking with some of you?,oh, of course, diesel, black smoke, right?, well most of a car's pollution starts at the power stations,so that arguement doesn't stand up,also, why not a diesel?,if BMW can make a performance diesel road car, surely it's not beyond the Bentley boy's too come up with an engine, a V8 diesel for instance?,or would this tramp on the toe's of their money makers?.If Porsche can make a sportscar with supercar performance and hybrid tech, whats stopping them?, too many toffee nosed well off's?.
