Watch: The Arteon’s 4Motion System Outperforms Quattro?

Among the many dark arts of automotive engineering, none has more resources being poured into recently than AWD systems. And few automakers have more experience in the field than Audi, but the new Arteon seems to be outperforming an A6 here.

It should be noted that, like any test, this roller test doesn’t necessarily replicate real-world conditions with perfect fidelity, but it is a useful comparison point for how these part-time AWD systems deal with zero grip on or more wheels.

While real-world grip may fade more gradually, the point of these systems is still to deal with varying levels of grip. And the Arteon manages to escape the rollers with up to three gripless wheels, albeit not without trouble.

That’s more than can be said about the Audi, though, which is nearly completely trapped when both rear wheels and one front wheel are put on rollers. The fact that Audi tunes its AWD system to funnel more power to the back wheels than the front ones may go some of the way to explaining that.

That makes it pretty impressive, though, that VW’s front-biased system manages to escape the rollers when only one back wheel has grip.

It should also be noted that this is a brand new Arteon and a 2016 A6, so this might just be the speed of progress. And it’s not like the A6 performs badly. Clearly, if you ever find yourself in a position where only one of your wheels has grip, the situation could fairly be described as bad even the most adventurous of vehicles.

Even though VW uses a system that was developed by Haldex, the GenV traction system was developed especially for VW’s transverse architecture, and it looks like they did a pretty good job.

Audis whose engine is longitudinally mounted (A4 and up) use Audi’s own Quattro system, which combines clutch plates (like the 4Motion system) in combination with a crown gear center differential.

In my own experience, Audi’s system tends to feel a little nicer through corners, but if I ever I have to drive through some rollers, I guess I’ll pick the VW.

Project SportWagen: Going Stage 2 with APR

When we last left you, the humble little SportWagen was fresh from the development process with our friends at AWE Tuning, sporting a new downpipe, exhaust and intake, allowing things to breathe a bit easier. The car sounded great, but there was no getting around the fact that our wagon was still quite, well, slow. While we realize that nothing we do to the Golf SportWagen at this point will make it a race car, we still felt compelled to do something . To put it bluntly, we had a fever, and the only cure was more power. Flash forward a few hours, and we found ourselves at Waterfest, staring down APR’s palatial spread and the numerous tuned vehicles surrounding it. Earlier in the year, APR had hinted to us that their 1.8 TSI files would be quite impressive, and based on what they were able to do with the 2.0 TSI found in the new GTI and our time in their Golf R, we knew it’d be worth the wait. So with this in mind, we lined our G...

Project Golf SportWagen- Intro

I’ve never really been one for SUVs and crossovers. The current offerings aren’t the body-on-frame, go-anywhere specialty tools I remember from my youth, and what they lack in capability, they also lack in on-road performance. The current crop isn’t terribly good at handling or being efficient, which in my opinion are major components of our ideal driving experience. So when it comes to space or utility, I usually look for something of the wagon variety- and it seems that I’m not alone. We hit quite a few shows around the east coast each summer, and we see modified Jetta SportWagens at nearly every event. Even amongst common consumers, these cars are highly sought-after. They don’t depreciate much, making even early Mk 5 2.5 versions expensive in comparison to other Jettas or Golfs of the same vintage. This year, Volkswagen launched their latest SportWagen, which is now billed as a Golf. In many ways, this latest SportWagen is the best yet and it has certai...

Volkswagen Group Records Best Ever First-Half-of-Year Sales

With 5.5 million vehicles in customer hands after the first six months of 2018, the Volkswagen Group is seeing the best performance of its history. Group deliveries increased significantly in all core regions,” said Fred Kappler, head of sales for the Group. “Our core brands recorded strong growth in the first half year.” For the year-to-date, all of Volkswagen’s brands had sales bumps. MAN, SEAT, and Skoda led the sales charge with performances 24%, 17% and 11% better than the previous year. The big sellers, too, had strong sales periods, with Volkswagen Commercial Vehicles, Audi, and Volkswagen sales rising 3.5%, 4.5% and 6.3% respectively. That last figure is particularly good new for the board, since Volkswagen alone sold more than 3 million vehicles in the first half of 2018. As Kappler stated, the numbers are equally good when you break sales down by region. Brazil and Russia were the most improved markets (22% and 20%, respectively), while strong sales in Europe and China (u...
