Why Audi needs a diesel R8: PH Blog

Go on Audi, have the courage of your Vorsprung Durch whatnot convictions!



I was interested to see a certain TV show's coverage of the second-gen Audi R8 the other night. Especially given I've just spent a few days in the car (not the one Evans puked in thankfully) and am currently sitting on my own review, wondering if a few nights sleeping on it will mellow my opinions. In the meantime I've got an idea I really think Audi should take up, partly inspired by my time in the SQ5 Plus

Namely, make us a diesel R8. Really. 

To think the idea made it this far before!
To think the idea made it this far before!
Just today Audi has issued a press release boasting of 10 years of diesel power helping it dominate a certain French 24-hour race taking place this weekend. The V12 diesel powered R10 TDI took victory at its first attempt in 2006, following that with two further wins to make it three on the trot. And off the back of that we got ... a V12 powered Q7. Cool car. But something of a missed opportunity to cash in on the trailblazing success of the R10. 

They teased us with an R8 V12 TDI concept back in 2008. Our colleagues at Autocar even got to drive it. But still no production car.

The naturally-aspirated 5.2-litre V10 carried over into the new R8 remains a weird choice of powerplant to me. It's a glorious motor that, weirdly, seems a bit anachronistic compared with the rest of the package. It fits a lot better in the closely related Lamborghini Huracan. So why not let it work its magic there, giving Lambo a real USP against the turbocharged McLaren and Ferrari rivals?

And sling that amazing V8 TDI from the new SQ7 in the back of the R8, to give us something properly innovative. At its best Audi is superb at this kind of thing - it was doing downsized twin-turbo V6s with huge power decades before the rest of the industry. And they still feel potent to this day. Looking further back it successfully sold us the dream of four-wheel drive, spectacularly proving the technology in competition before masterfully exploiting its marketing and functional potential in its road cars.

There's a tangible motorsport link too

A TDI R8 would be something properly stand-out as rivals struggle to translate long-held tradition into the downsized turbo age. Audi's strength is in not getting hung up on nostalgia and pressing ahead with a technical agenda others would fear to explore. A 435hp diesel V8 with 664lb ft of torque, electrically assisted turbos and a clear technological link to the cars that have dominated Le Mans for much of the last decade would be super cool. If anyone can do it Audi can. And while it might not be as obviously 'emotive' as a screaming V10 I think the power delivery and performance would more than make up for it. And it would sure as hell make the R8 stand out among the 911s, McLarens and other cars it competes with. It doesn't have to be either/or - keep the V10 Plus in the range too but make the TDI the signature product. And give us something genuinely different. 

It's funny. A lack of self-confidence isn't something we usually associate with Audi. But, faced with a seemingly golden opportunity to 'own the space' and do something truly radical, it seems uncharacteristically hesitant. 

C'mon guys. Give it a go!

Often wondered this. It's the elephant in the room of the entire Audi range.

yeah bring out an R8 oil burner just as the EU / UK / local town planners tax them into oblivion

smart move biggrin

Nope, the Diesel TT is bad enough imho

If you can afford an R8 yet are concerned about mileage/fuel cost, buy yourself a diesel barge for the long runs instead.

You've got a glorious NA V10 and you want to swap it for tractor power, are you mad?

Sticking an elephants head on top of the roof would make it different and stand out from the competition too, doesn't mean it's a good idea or that it's something anyone would want. Though I expect there are many more people in this world who would be interested in an elephants head on top of their Audi super(?)car than a diesel engine powering it.

A depressing opinion, if genuine. There are few things the world needs less than another Diesel powered car. We are only just waking up to the legacy that mass DERV adoption has left us, and now you want one of the few remaining untainted automotive categories (supercars) to buckle and accept the inevitable?

There would nothing innovative about a Diesel R8. Simply politics, fashion and marketing. True innovation would be manufacturers rebutting heavily compromised and dubious Diesel technology in favour of something better suited to the application.

I'm not saying they do it for those reasons, purely the performance ones. Many of the latest crop of petrol turbo performance engines have very diesel-like power delivery anyway - why not celebrate that and explore the performance potential of a properly set-up supercar diesel engine with a direct link to proven Le Mans glory. Zero lag thanks to electrically driven compressors, variable lift to permit a wider rev range and higher redline than diesels traditionally have - it's all there already in the SQ7's V8 TDI and ready to be calibrated in a way that makes it interesting in an R8.

It might not be The Answer. But it would be interesting. And different to what everyone else is doing.

Keep it coming!

No one needs an R8 diesel. In fact no one should have a diesel car in my opinion. Diesel has no place in a passenger car. It only has because of some misguided bks on emissions....and look how that's turning out. In the US petrol is king, in Japan they've never really gone down the diesel passenger car route. They only ended up developing diesels to suit Europe. Honda used to re badge old ISUZU engines!

Audi should really be making the R8 hold the kind of energy recovery system they have on the Le Mans racer. Put the V8 back in (because the V8 sounds way less anodyne than the V10) and get some electric motors on the front wheels or something.

This kind of hybrid tech seems so far limited to the ultra hyper cars (P1, 918)... I am sure there is room for the same kind of stuff on the level of the R8.

You all seem to be missing the point Dan is trying to make.

Audi is WINNING with diesel performance cars.

Audi won with quattro, then that came over into its car range and became its flagship "feature" in all its highest performance cars.

Why not diesel V8/12's too?

In theory it should be possible and the car would probably be epic. However I think the recent issues with the diesel emissions and peoples perception of diesel have killed that idea. No doubt an electric hybrid petrol turbo is in the R&D labs as a priority instead.

So in other words a "petrol" style engine but burns diesel instead???

Yes, it would be interesting, on one level at least. Different, certainly.

The problem is, they're running a business, not a tourist attraction. Who exactly is going to buy a diesel R8?

Audi should be praised for sticking with a screaming NA V10 in what is perhaps the most mainstream of supercars, not criticised and asked to fit a bloody truck engine instead.
