Quattro's new boss: PH Meets
Heinz-Peter Hollerweger talks diesels, hybrids and the importance of ludicrous power for future fast Audis

Earlier this year Quattro GmbH's then-boss Franciscus van Meelsuddenly left to head up Audi's Chinese operations, after reportedly falling out with the company's overall product supremo Ulrich Hackenberg (we can only presume the head of Audi Siberia was already taken.) Since then, perhaps not altogether surprisingly, van Meel has left Audi and will shortly be taking the reins of BMW's M-Division, following the retirement of the genial Friedrich Nitschke. Meaning that Quattro also has a new boss, veteran Audi engineer Heinz Peter Hollerweger, who we spent an illuminating 30 minutes with at the Paris show.
In corporate terms, Austrian-born Hollerweger is the safest pair of hands, an Audi lifer whose last job before Quattro was as overall head of vehicle development. The good news is he's certainly not a corporate clone, attending the Paris show wearing a jaunty cravat in stark contrast to the grey-over-grey suits of most of his colleagues. And although Hollerweger doesn't quite match the fearless honesty of Hackenberg - a man who has been known to discuss the finer points of his five-year model plan while PRs slit their wrists in the background - he's certainly happy to tell it like it is.
We start with the thorny question of diesel-powered RS models. Audi has been dropping some very broad hints that these are going to happen, none broader than letting hacks have a go in a prototype with "RS5 TDI" written on the side of it, but Hollerweger insists that diesel RSes aren't a done deal yet. "That battle has not been won yet," he says. "It's one of the battles, but I have to say it's mainly a European battle."
When pressed harder, Hollerweger raises the interesting prospect that high-performance diesels might not be full 'RS' models, with Quattro effectively creating an equivalent of BMW's M Performance diffusion line. "I'm not sure if you should weaken the strength of the RS brand with two different engines [in the same model]. But I could really imagine having some design elements and performance elements of the RS with a diesel engine. Whether it's called 'RS' or not I don't know, it's not decided."
There's positive news on the division's existing powerplants, with Hollerweger confirming secure futures for both the warbling 2.5-litre five-cylinder and the almighty twin-turbocharged V8. Audi's announcement earlier this year of a 400hp version of the existing EA888 four-cylinder turbo seemed to make the five-pot redundant, but Hollerweger confirms it will be developed, hinting it will produce substantially more power "I think that 400hp is not the limit of the five-cylinder at all," but also that Quattro still wants its 'own' powerplant for the junior RSes. "I think its value is not only pure power. It's an exciting engine, the sound and the feel is unique - and it will have significantly more torque at low revs."
The twin-turbocharged V8's future also looks rosy, with Hollerweger's refusal to confirm that power levels have peaked effectively confirming a plus version of the RS6 and RS7, likely to have around 600hp - "I think people with money still like to buy horsepower." He also said that Quattro will continue to develop V8 engines for next-generation models, and even hinted that the next RS4 and RS5 will be sticking with eight-cylinder power rather than following BMW down the downsizing route. "Look at Mercedes," he says, "they have introduced the C63 with an eight cylinder." He didn't quite tip a comedy wink at this point, but it wasn't far off.
The really new news is part-electric powertrains, with plans clearly advanced to bring some volt-based assistance to RS models. Separately at the show Hackenberg said there would be a hybrid version of the next R8 in conjunction with the fully-electric E-Tron, and Hollerweger confirmed that work is advanced on producing part-electric powertrains, with Quattro's role as a technology leader meaning its products will be used to showcase new performance technology. "High performance electric driven cars or part electric cars don't need to use a big battery at all. There's no engine that has better torque at zero revs than an electric [motor], and I believe you can adopt it into a high performance car without carrying 250kg or even 150kg of batteries."
He also confirmed that the electric turbochargers that Audi has been talking about for several years will be here very soon, with the move to 48-volt electrical systems making them possible. Active 'performance' aero is also coming, in addition to the sort of efficiency-boosting active systems that Audi AG is working on.
When it comes to growing Quattro, Hollerweger takes a relaxed approach. "It's hard to say if there's a natural size for the number of cars we products - maybe 15,000, maybe 20,000, maybe 25,000," he offers. "But the important thing is to make sure the cars are right, not to aim at growth at any price. If there's a natural growth, that's great - but I want to keep RS models as niche models, not mainstream models."
So does that mean fewer RS versions? Probably not. "I wouldn't say it's necessary to have RS models for all, but I cannot say 'this is too small' or 'this is too big' - an RS1 could be a nice alternative, even if there is a very small market for these cars - as well as an RS Q7. I certainly wouldn't exclude that for the future at all."
A good friend of mine treated himself to a new RS5 last year. I was lucky enough to have a go in it. A heck of an experience in many ways, mostly thanks to the face distorting grip, and the frankly ridiculous acceleration and soundtrack combo that just makes you laugh out loud. That V8 at 8000 RPM on wide open throttle makes a noise to die for. Sadly the rest of it was aloof and uninvolving. I'm not a CH powersliding God, but I do expect to feel connected to a car, and I had no more sense of what the front wheels were doing than I get in my £28k 320d. OK the RS5 could carry ridiculous speeds into corners, slingshot out of them with amazing grip, and reel in straights at a rate like nothing I've ever driven, but I never had that yearn to drive it more, to learn it better. In terms of raw pace, nothing I've ever driven would see which way it went on pretty much any road, but it was a one (or two) trick pony. Grip and pace, both amply demonstrated within a mile of driving it. Fun? Long term interest? Take the soundtrack and pace out of the equation, and no, not for me.
All the tangible technical bits nailed, but just missing that last bit of tweaking by a keen driver. But fast Audis look good, go well and are impeccably finished. A set of qualities that have served them well enough until now.
diesel RS, meh, meh and thrice meh
glad the glorious 5 pot is staying, but hopefully they will take the marketing restrictor of it this time and let it run at 400bhp
hopefully the next RS4 will be a blown v8, its a glorious engine when on full bore but very weak as a daily driver

Back to topic:
I guess Audi are using the same technology Volvo showed in that recent video.
I agree that the RS4/RS5 seems a bit thirsty compared to an S4/S5, and Audi appeared to restrict the 3.0 TFSI by bleeding off the supercharger boost way before the power peak (unless that's sometimes standard practice to control heat?). That makes me think the supercharged 3.0 TFSI may be used in the next S4/S5 in a 'de-restricted' version with 414hp/420ps.
A 2.0 TFSI with a biturbo and electric turbo will be in the next S3/TTS with 355hp/360ps.
Same tech in the 2.5 TFSI will be in the next RS3/TTRS/R8 'V8' with 444hp/450ps.
Same tech in the 3.0 TFSI will be in the next RS4/RS5/S6/S7/R8 'V10' with 532hp/540ps.
Same tech in the 4.0 TFSI will be in the next RS6/RS7 but will be launched in the Lamborghini Estoque with 690hp/700ps.
All speculation but from what he said I'd also put money on Audi will put a 414hp/420ps 3.0 TDI biturbo+electric turbo engine in an S6/S7, to rival the M550d, and will also put it in an S4/S5 chassis to create a TDI version of that car.
They already have an RS sub brand called "S" and already produce the SQ5 which is a high performance diesel with S branding.
So the sub brand is there, the diesel precedent is there, so they should just get on and do it.

But from my experience of those who own them, they make sense:
A) like the grip and power, the fact it's an Audi, good interiors, not interested in driving dynamics beyond go, stop, grip.
B) like driving, have more focused cars in the garage for pleasure, like the Audi for everyday grunt and AWD security, accept it's not a car they grab the keys for when seeking thrills.

The RS6 really shows up how weak the engine is in daily duties
Now if you could match the RS6 engine with the superb RS4 gearbox (the 6s box is an old school dim witted affair, so it's best just left in sport) in the B8 that i would buy
The new M3/M4 engine is far better suited to a daily driver as well

not sure what gearbox you have beef with though, the 8 speed ZF is awesome.

But if I could I would have the blown v8 with the 4s duel clutch
