Final nail in the coffin of the RS brand?

If it really can return decent mpg figures then I have no problem with it at all.

I would buy one if I could afford one - comfortable good looking car that is good on fuel for 99% of my driving, and goes like hell for the 1% that you want it to.

I suppose it depends what the long term reliability is like too, but I imagine it will be good as the 3.0 TDI is a robust unit.

I expect to be slated for thishehe

Don't you care about how a car sounds?

The B5 RS4 was hardly a great sounding car.

It's also a 15 year old car too.

Exhaust, engine and computer technology has moved on significantly since then.

Er, yes, and it's not a diesel!

i think it's a diesel hybrid
some performance diesels actually sound alright once they get going, the main issue i have with the sound of them is the diesel chug and rattle at idle
but since this looks like it is a hybrid it's probably going to be very rare to hear it idle

Have you ever heard a pleasant-sounding diesel?

Then why do older performance cars tend to sound better? wink

Well it says electric turbo on the side. Without reading the AC article I assume this isnt a hybrid, but some kind of electrically driven compressor or something like the electric machines they have on F1 cars currently (but are also being developed for other uses such as large HD Diesel engines). These are turbos with high speed electric motor-generators inbetween turbine and compressor wheels. Helps with transient running and they are most impressive in drop-load testing, where you whack full load on instantly. Really improves the engines response by eliminating turbo lag.

Indeed, my OH's dad has a new S-Class. You wouldn't know it was a diesel even from the outside stood next to it. Its idle is remarkably quiet, it really is almost petrol like.

If it can do a sub 4 sec 0-60 and lashings of low down torque, I can see this as a viable option. Calling it a RS given it's performance, is a way of not having it trounce a petrol RS whilst on a S badge.

That would be silly marketing - 'here's the new diesel S5 - quicker than the RS4'!

Personally I'll take the crappy sound at idle in exchange for the fuel economy without any real world performance deficit over the equivalent petrol. Which is why I'm on my second diesel SLK.

Without reading the AC article, you've nailed it!

It's not about whether they are quiet or sound unpleasant, but whether they have a sound that excites, like the 4.2L Audi V8. Can anyone name a diesel engine that sounds exciting?

It didn't/doesn't sound like a 850 mini either. It was a bit muted though on the standard exhaust I'll admit. Adding a Miltek changes it somewhat.

Not really and it's not something that Audi could market.

They should pop on ebay, get an electric supercharger for it as well.

Yup, I agree, nail in the coffin for the audi rs range.
And I've NEVER heard a diesel engine that sounds 'good'. Some of you are clutching at straws.
