Diesel supercars

[Dieselman]

o- 60 for the petrol is 4.0s .Still faster than the diesel.

As you well know 0-60 is more about traction and weight than outright grunt, try any in gear accelelration and the diesel wins by a country mile.

And your forgetting something, the petrol only wins 0-60 due to revving higher so can run shorter gear ratios...but has criminal fuel economy and emissions as a result.

And 25mpg is pretty darned good for a supercar, what does your C180 achieve?

I know it isn't a Mercedes, but what do folk think?

I rather like it...

I saw the Audi Diesel Le Mans thingy a couple of years back at the Goodwood Festival of speed.

The techs fired it up in the paddock beyond our line of site and my mate and I were looking at each other going "what the f**k is THAT??" (the noise was awful). We wandered over to it and immediately regretted it - it was putting out billowing clouds of acrid black smoke. When it eventually went up the hill the nosie and smell had died down - it didn't stink anymore and sounded like, well....dull.

It just seemed wrong. From a spectator's perspective diesel is not the way to go for motorsport. Well, except I guess the odd light rain on a diesel spill might make for some spectacular cornering incidents. Although I wouldn't want to be racing bikes round the track once the Audi had been round......

Fuel economy is not on the mind of people who buy cars like that and my C180 does a lot better than the diesel R8 in the real world economy stakes.
I doubt if it would even achieve 20mpg on the road.
If the diesel starts struggling to breathe after 4k revs well that is not the petrols business.

No, your right! Its just a very quick digger!

and your fast digger in the 21st century is still slower than a railton and a golden rod chrysler petrol from the sixties.

talk about advancement in diesels

I find that the powerband in a modern Diesel is wider than a Petrol. Where I have to work a petrol engine hard the Diesel produces more user friendly power low down.

Not sure about in a supercar though!

Diesels do produce more torque lower down but they dont produce the hp so run out of puff and the power drops off steeply

Most are done and dusted by less than 4000rpm , most decent petrol engines rev to 6000rpm+

I think the diesel R8 is a good idea, though whether it will ever make it into production and/or sell well is another matter. Diesels are getting more and more popular on the road, due to a variety of reasons. it used to be that diesels were only for the farmers or skinflints amongst us, but that's no-longer the case and some pretty fast diesels have been appearing.

The diesel R8 is, to me, more a showcase of what diesel is capable of. and that there are other ways to look at things, and other driving styles that might be catered for. as already stated, diesels have a narrower power-band, but there tends be a lot of power there, and you often don't have to run up and down the gears so much as there is loads of torque allowing you to take those corners in a higher gear than you might think.

And as I recall, the reason Audi chose to put a diesel in their lemans car was not fuel efficiency or emissions, but they wanted that wall of torque. the car won and some more diesels are entered into next year, so it has some racing credentials at least.

25mpg for a supercar is pretty decent, and your high earning celebs can tout some sense of environmentalism with the lower emissions (not that I can find it stated what they are, just that they are low and comply with eu6).

If they can adapt their DSG gearbox to suit it too then that would make for a very interesting car as it can zip up and down the gears in tune with it's narrow powerband. (ps chaps, have a word with those bugatti chaps, they got it working). and don't forget that it might well be a very interesting second hand buy. a supercar that might not be in all the top bands for fuel economy and emissions, and might be allowed into london

if they release it, then the market will determine how well is sells and I'll be interested to see how it works out, and if it spurs on a spree of similar type cars.

and if it spurs on a spree of similar type cars.

Oh my, an AMG TDI?

I have just been wondering about a diesel convertable, on the basis that using less fuel, and having cheaper road tax, means Darling and his condescending voice and bushy eyebrows will get less out of me over the year, but one can driver thru the country, open topped, in the knowldge that the next generation won't have 8 arms and blue skin due to my emmisions. And while driving in the country I am not sure it will make any difference if I sound like a tractor.

I may report back, if I find out if the desired car has a quite engine, enough room, and has a nice ride, rather than sporty.

I may not bother to make the move as well. what with it being a "other" German car. The shame of even thinking such things.

I think when the economics come to it. Mr darling will significantly put up the diesel prices to counteract the loss made from people switching. when diesel becomes twice the price the price of perol, the MPg figuew will not look that good,

 

[scumbag]

He would have his work cut out if everyone changed to low polluting cars this year and nobody got the high road tax cars. His economy would have a bit of an issue.

Not like Ken when he saw how effective his congestion charge was. He didn't put up the bus prices, nor increase the area to make up the deficeit.

Still, if they can get rid of the vibrations in deisels, and remove the noise, I don't really see the problem with a supercar idea.

JCB might start making cars then?

don't they make a CLK320 CDi droptop? would that not do you?

I personally might be more tempted by a BMW 330d convertible (afaik, they don't do the 335d in convertible form sadly) but either way, it should be good open top motoring...

 

[BTB 500]

don't they make a CLK320 CDi droptop?

No ... M-B don't do any diesel convertibles (edit: in the UK). Unlike BMW, Audi, SAAB, etc.

 

[scumbag]

don't they make a CLK320 CDi droptop? ..

they do , but its a left hooker, and it mite do but it would be better with the next generation deisel I think if they made it right hand.

Audi/VW and BMW all do one. As do Volvo and SAAB. The volvo appeals due to its hard top, I have not taken to the Audi interiors, and I just can't get along with the 3 series. The 1 however looks the part to me.

And as far as Saab is concerned, I think I would rather have the Astra thanks.

oh, that's a shame. I suppose I assumed the existence of the diesel from the coupe.

I quite like the new 3 series droptop. it's a hell of an improvement on the saloon certainly.

or, for the more well heeled in the audience, how about a new BMW 635d convertible? quick too.
