40 years of Audi 4WD: Quattro and RS2 meet R8 and RS6

40 years of Audi AWD: Quattro and RS 2 meet R8 and RS6

It’s now four decades since Audi introduced the world to all-wheel-drive performance cars. We climb down the Quattro family tree.

Almost all cars reckoned to be true pioneers turn out to be nothing of the sort. The Range Rover wasn’t the first luxury off-roader, the Renault Espace wasn’t the first MPV, the Volkswagen GTI wasn’t the first hot hatch and none of the Saab 99, Porsche 911 or BMW 2002 was the first turbocharged road car. And the Audi Quattro wasn’t the first high-performance all-wheel-drive car.

That, of course, was the English Jensen FF produced between 1968 and 1971. But like all of the aforementioned, the Quattro was the one that perfected and popularised its innovation. The problem with all previous all-wheel-drive cars, Jensen included, was that they needed to direct their power forwards through a heavy, clunky and bulky transfer box. This solution was impractical and expensive, which perhaps explains in part why just 320 FFs were built. What Audi did was find another way of doing the same thing.

It was Jörg Bensinger who realised that if you used a hollow output shaft from the gearbox, it could run into a centre differential mounted behind the gearbox, while a second shaft within the output shaft could then take the power forward to the front wheels. The need for a transfer box was bypassed and the first modern all-wheel drive system invented.

Bensinger and his team started work on this in the mid-1970s, but it wouldn’t be until 1980 that the fruits of their labour could be seen in public, in the form of a boxy coupé called the Audi Quattro. Since then, Audi has never stopped using all-wheel drive, and it has now been joined by most of the world’s other major car manufacturers.

But for Audi, all-wheel drive proved far more than just a means of halving the tractive work load of each tyre. Quattro started life as a car, soon became an automotive legend and then turned into a sub-brand, to Audi what M is to BMW and AMG is to Mercedes-Benz.

But which Quattro machine is the greatest? With hundreds to choose from and only five examples allowed, it wasn’t an easy process, especially as two places were already bagged by the original and the most recent.

Many will disagree with the chosen quintet, but I went for the final version of the original Quattro; the RS2 Avant as the first of the truly nuts estates for which Audi became so renowned; the original TT because it was a design revolution that did far more to democratise the sporting all-wheel-drive coupé than the Quattro; the Mk1 R8 because, well, it’s an R8; and the latest RS6 Avant panzerwagen. I know: no V10s, no RS4, no Sport Quattro, no SQ2… Okay, perhaps we won’t be shedding too many tears over that last one.

The benchmark is, of course, the Quattro. I’m old enough to have tested late 20-valve examples like the one we have today when they were new and recall most of all just astonishing point-to-point pace. But even though the Quattro had been on the market fully 10 years by then, I don’t recall it feeling old.

It does now. The strange driving position, even stranger gear ratios, arcade-game electronic dashboard and acres of hard plastic all speak of another era. The gearbox is quite clunky, while the engine is surprisingly lethargic off-boost, even for its age. At low speeds, it feels quite awkward, rattly and cumbersome. A disappointment, you might even say.

But then the revs rise and you hear that noise (how to describe it without saying ‘off-beat thrum’?) and discover that what has not diminished one bit over the decades is the sense of occasion. It’s still fast enough to be engaging, clocking an easy 200km/h before that unforgiving shape finds it increasingly hard to bludgeon the wind asunder.

It’s still fun, too. Grip, the commodity for which it was most famed 30 and 40 years ago, is actually quite modest by modern standards and it still understeers, but the steering is lovely and the chassis is far more adjustable than I recall.

That’s not something I’d say so readily about the RS2 Avant. Like so many of the crazily rapid RS estates that followed it, the RS2 is absolutely at its best in a straight line. But it also feels from a far more recent era, for while they missed each other by just three years, the Quattro and RS2 feel a generation apart. The latter is a modern car, you might say.

It’s incomparably better built, and from far better materials. This may have something to do with the involvement of Porsche, which was in such dire financial straits at the time that it had to earn money on the side by engineering cars like the RS2 and, before it, the Mercedes-Benz 500E. Zuffenhausen’s involvement certainly explains how the output of essentially the same engine rose from 162kW in the Quattro to 232kW for the RS2.

The car remains as funny as ever. It looks brilliant and oozes promise as you settle into the chunky Recaro driving seat and survey those black-on-white dials. Lag is, of course, prodigious from a 26-year-old road car engine providing more than 105kW per litre, but once it’s past about 3500rpm, it will still surprise you by how hard it hauls, and over an unexpectedly wide powerband. It hit 225km/h in the same space the Quattro needed to reach 200km/h.

If only it were as good at changing direction. It clings on, of course, but we must remember this was the first of the doggedly understeering high-speed Audis and old habits die hard.

The TT you enjoy for other reasons. I will take engineering over design every day, but you can’t just climb into the TT and set off. First you have to sit and survey the interior, with all of its unique and lovely touches. I understand absolutely why it was such an enormous hit: it looked and felt not like a platform spin-off sharing as much componentry with its brethren as possible but a genuinely bespoke product.

It was built properly, too. This one has done 216,000km and still feels taut. Perhaps the TT deserves reappraisal from those of us who were slightly sniffy about it when it was new. It’s no Porsche Cayman for sure, but its 165kW 20-valve engine is eager, its six-speed gearbox a genuine delight and its handling more poised and less nose-heavy than I recall.

The R8 is, of course, the anomaly here: it’s the only genuine supercar Audi has made, the only mid-engined car and the only closed two-seater. And although its appearance, interior and quality are all very traditionally Audi, the way it drives is not. Indeed, for the sweetness of is engine, the precision of its manual gearbox and the deftness of its chassis, this early manual V8 car is every bit as credible a high-performance driving machine as any standard Porsche 911 or Aston Martin Vantage from the same era.

It may be rather lacking in horsepower compared with a modern R8, but it’s still plenty fast enough to register over 240km/h in short order and more than sufficiently rapid to feel restricted by the confines of the public road. What’s more, unlike so many quick Audis, it’s a car of the most exquisite balance, and I mean that both literally and figuratively.

First, it’s refreshingly resistant to understeer and, despite almost unlimited traction, very happy to tuck its nose into an apex and let its rear run wide. But second, it doesn’t feel overpowered: the relationship between power and grip is spot on, allowing you to slip easily into a delicious rhythm, which is a defining characteristic of a great driver’s car.

That brings us to the new RS6 Avant (grey car below), which is interesting – and not just because it has 441kW and will do 0-100km/h in 3.6sec. What holds my attention more firmly is a distinct sense that, at last, Audi is trying to do this kind of car slightly differently.

Yes, it ticks all the boxes from outlandish power to outrageous appearance, but such strengths in the past have flattered mainly to deceive. However, with a more neutral set-up and a far greater feeling of agility (thanks no doubt to four-wheel steering), it’s not just comical in a straight line (it indicated 290km/h with ease) but also has something to offer on the perimeter road. It’s still not the best-handling fast wagon out there, but it has better steering, sharper turn-in and more front-end grip than any big Audi estate of my acquaintance.

So, it would be hard to overestimate the benefit to Audi of that little word ‘quattro’. It started life as a niche product with very modest ambitions and became, as Quattro GmbH, the halo brand for the entire brand. Yes, it was renamed Audi Sport back in 2016 (which I always thought a shame), but the idea of using Quattro not just as a technology for making its cars easier to drive but as standard-bearer for the marque, emblematic of its entire philosophy, has played a pivotal role in the transformation of Audi from the bit player also-ran it was in the 1970s to the enormous organisation it is today. It may not have saved the company, but it is no exaggeration to say it helped make it.

As for our famous five, it seems iniquitous to order cars so separated in time, space, performance and concept. But I’ll share with you now that there are some really good cars here and one absolute titan.

The Quattro has significance and charm, but it feels pretty limited these days. The RS2 isn’t as rounded in its abilities as you might hope, but it’s hilarious, it looks great and it’s by far the rarest. And for completely different reasons, both the TT and RS6 are far better than I expected. But that early manual R8? Wow. It’s not just a great Audi, it’s one of the finest examples of that kind of car from its or indeed any other era.

Five more significant Quattro cars

1984 Sport Quattro: The Sport is the 1984 Group B rally homologation special Quattro with mad looks and a comically abbreviated wheelbase. With 228kW, it was the fastest Audi road car ever produced. And with just over 200 examples made, it remains the rarest to this day.

2008 RS6, RS6 Avant: Yes, this is an Audi A6 with a twin-turbocharged 5.0-litre V10 derived from the normally aspirated version fitted to the Lamborghini Gallardo. And with 426kW, very little less 12 years ago than the new RS6 Avant has today, it was absolutely as nuts as it sounds.

2008 Q7 V12 TDI: In many ways, this is the craziest Quattro car yet, here not because it was great per se but because it remains the world’s only diesel-powered V12 production car and had 1000Nm. Which meant it could tow Blenheim Palace without really noticing.

2012 RS4 Avant: For those looking for the best Quattro all-rounder made to date, look no further. It wasn’t the first to use the 4.2-litre V8 from the R8, but it was one so much sharper and more fun to drive than its predecessor. Superb looks and outstanding quality complete the picture.

2020 E-Tron S: Quattro enters the EV era. Electric torque delivery means there’s a greater need for four-wheel drive, while the flexibility of layout makes it far easier to provide than before. Audi’s 40-year love affair with all-wheel drive is about to find itself a new relevance all over again.
