Although somehow at the end of its life Saab introduced a car with four-wheel drive to the market, by all accounts it could have been much earlier – even before Audi and their XWD drive which they branded as “Quattro“.
Most of us know that it was the top model in the Saab 9-3 program that was branded as “Turbo X“. It had a 280hp Holden-sourced V6 turbo engine, with the then latest advanced four-wheel drive with automatic rear-axle differential lock and plenty of body tweaks to make it look like a ‘street racer’.
In addition to the “Turbo X” model, which was produced in a limited series, the much cheaper 9-3 with four-wheel drive was also available to customers. A typical representative of this version was, say, the model Saab 9-3 2.0T XWD. The Saab 9-3 2.0T XWD can be seen as a lightweight version of the top model. It has a slightly smaller engine, slightly less advanced four-wheel drive and slightly less body tuning, and it is interesting that the result is a more successful car at a price lower by almost one third.

But how did Saab get the XWD model?
If we look a little more into the past, we could see that the XWD drive could have been a symbol of Saab, just like the FWD, even before Audi and their Quattro drive. And the key link between Saab and Audi with four-wheel drive is the Johansson family and their huge contribution to the auto industry in general.
Although there were several from the same family, Sigvard Johansson was perhaps the most significant. Sigvard was a Swedish engineer and inventor of the so-called Haldex coupling, which is now found in many car brands around the world.
The Haldex clutch
The Haldex clutch is a component of the drive system with a second axle (front or rear) that can be connected, which makes the machine four-wheel drive. This component ensures smooth connection of the axle when the main drive wheels slip. The amount of torque directly depends on how tightly the clutch is clamped (discs in the structure of the mechanism).
Sigvard Johansson
Designer, inventor and racing driver Sigvard Johansson was born in Långasjö in Småland and was attracted to Trollhättan and Saab in 1959. Johansson was loyal to the SAAB company until 1984, when he had already started several of his own companies, such as Grunneboföretaget IPU AB, for engineering and prototype development. Among other things, he invented his own compressor and a new method for belt tension.
Peter Johansson
Johansson married Ruth Gun-Britt Johansson on April 21, 1962. and in November of the same year they had a son, Peter. Continuing his father’s mission, it was Peter Johansson who was one of the key people at Saab who integrated Haldex four-wheel drive into Saab’s 9-3, many years later after Peter’s father invented the Haldex coupling.
Haldex XWD – How did it all begin?
Motorsport was Johansson’s great interest and he drove track races in his younger days. He had great success in racing, both in track and ice racing competitions and has won races at the Nürburgring in Germany.
When Johansson was testing his son Peter’s rally car (later Saab 9-3 Turbo X test driver and demonstrator), he got an idea and constructed what would become sensational world news. It was a unique clutch for four-wheel drive, which eventually became known as the Haldex clutch. He received a patent for the invention in 1988, and in 1992 the company Haldex took over the production rights and started serial production of the clutch in Landskrona in 1996.
Johansson could be happy that his invention was thus included in all cars of the Volkswagen Group with a transverse engine, and therefore also in the legendary Audi. Today, the clutch is found in over forty brands of cars, then the latest generation of Haldex (generation 4) is found in the Saab 9-3 XWD (Turbo X).
Haldex Traction
The Haldex Coupling (First generation) made its first appearance 1998 in the Audi TT, Audi S3 8L and VW Golf with an electronically controlled hydraulic-mechanical all-wheel drive concept. Haldex Coupling is a slip clutch that transfers torque from an input shaft to an output shaft to make cars four wheel drive.
When the front and rear axles of the car rotate at different speeds, a hydraulic pressure builds up in the clutch. This pressure is used to press together a number of lamellae so that the torque from the input axle is transferred to the output rear axle. A finesse is that the construction works in both directions, which means four-wheel drive even when reversing. In addition, power can be transmitted either from front to back, which happens for example in cars from Saab, Volvo and Volkswagen/Audi, or from back to front as in the Bugatti Veyron.
Later versions of the clutch have an electric pump, which can fully or partially pressurize the clutch. In this way, you can get four-wheel drive to prevent the car from skidding, not just to dampen a skid that has already occurred.
The Haldex clutch was invented by rally driver Sigvard “Sigge” Johansson, but is named after the Swedish company Haldex that developed it. The part of Haldex that manufactures the Haldex coupling was sold in 2011 to BorgWarner.
How could a Saab be a “Quattro”?
If there was a little more luck and listening on the part of Saab management, and a little later GM management, Saab cars would have integrated and offered four-wheel drive in their cars long before all other manufacturers. Just as was the case with Turbo Chargers.
If there was enough understanding on the part of Saab management at the beginning of the 80s of the last century, already then, buyers of Saab cars around the world could drive safer (compared to the prevailing FWD) XWD machines.
If that were the case, Sigvard Johansson would have developed his invention within the Saab company and it would have been integrated into the Saab cars of that time. It would be similar a little later, when Sigvard’s son Peter was in the Saab company working on the same development tasks.
At the Saab company, a lot of work was done on the integration of the drive on all four wheels (AWD)
It was Peter, with his considerable driving skills and deep involvement in the development of four-wheel drives, who expressed regret during a promotional drive in Australia in 2008. In 2008, Peter Johansson stated that he had spent more than twenty years at Saab working on the development of an additional three advanced four-wheel drive systems(!), none of which General Motors deemed fit to bring to market?!
Peter was particularly saddened by this fact of denial by GM, because in addition to him, two more generations from his family worked in the development of the Saab company, right from the very beginning after the Second World War.
Why does Audi have to reap all the laurels?
During those test drives by Australian journalists at GM’s test track, Johansson complained from the passenger seat about SAAB’s position at the time – describing how unfair it was for companies like Audi to get all the credit for AWD. And all because of GM’s refusal to implement AWD for the Saab brand until that moment.
A very interesting read, what could have been another Saab first!
That’s a great article.
And why…… Should just have made good quality cars, money wasted on things when a decent quality car would have kept them going
Look at how many cars in SAABs class now have AWD. They needed it to remain competitive. As for making good cars, GM insisted on using the Opel Vectra platform to save costs, but it also meant the Saab engineers had to work within the constraints of that older generation chassis.
Great article! Thank you for sharing! And yet another sad example of how corporate business models sometimes kill brilliant idea’s from passionate professionals. The brilliant idea lives on and find’s it’s way but a valuable opportunity that could have served the bigger picture, for Saab in this case, was sadly lost.
I love Saab, but no. This article is very frustrating to read. For one, four wheel drive, as they keep referring to it as…is not the same as AWD. The Haldex clutch used in these vehicles, or at least with the VAG cars, are on AWD, not four wheel drive. And for Audi and Quattro, there is more to it than using the Haldex clutch system primarily found in the smaller vehicles. Most Quattro uses the Torsen differential. The Torsen differential is very different from the Haldex used on Saab XWD. The Audi Quattro Torsen system was introduced in 1980 on the Quattro model. In the end…two very different AWD systems. Stop calling it four wheel drive when it isn’t. This article needs a re-write.
The essence of the article is not which system is better, Audi used both external sources – the essence is how much expert knowledge Saab’s internal engineers had and additionally, what would have happened if the management of Saab and later GM had recognized the values (40 years ago ) – the question is how this technology would be developed further in Saab itself.
A possible guess would be that maybe Saab would develop in-house a much better AWD-XWD-4WD (whatever) than these available
Still think it is a great looking car
I have both manual and auto Turbo X
Great in all weather conditions.
I loved my 9-3 Aero 2.0 6-spd. XWD. I’d still be driving it if parts were available.
Well original Torsen quattro (not the Haldex stuff) was in series production 86 so before Haldex got the patent, so in short, no. And Haldex is not a superior layout anyways, with its use in front transverse cars as a hang on coupling to the rear..
I had 2 beautiful Saab convertible’s. And I’d still have one instead of my new S5 convertible, if only they did the vert’s in XWD. 🤷🏻♂️
I was in the SAAB factory back in 2004 and they unveiled what would be the new SUV. It never came to light. Well it kind of came delight is what the Cadillacs look like now.
Es que un audi lo puede tener cualquiera, un saab no.
Un saab no es para todo el mundo.
Nadie cambiaría un Porsche por un Audi, pero muchos si que cambiarían un Porsche por un Saab.. por difícil que parezca creerlo.
Por cosas así Saab jamás necesitará que uno de sus coches tenga la insignia de xwd, Quattro, Gti, Rs……
No.
Para que quieras un Saab solo necesitas una palabra en la parte de atrás:
SAAB.
Aquí estoy sentada en mi 9.3X gasolina con XWD, disfrutando de su autenticidad
The Saab management story really should be taught in business colleges. It’s classic and still a timeless case of failures.
I got the slow XWD and in the snow and ice on all season tires. You could feel power being sent to all the wheels and in a sticky area you can feel the car sending power to different wheels trying to find grip and it wouldn’t cut power it just kept trying to
It always comes back to crap decisions by GM
But the man working for Saab quit.
