Kizashi AWD - Facts, Myths, and Impressions

Anything related to the Kizashi can go here, but please look at the other headings first. Your topic may fit better under something else.

Fair enough, but citing Tony Devers in the article doesn't overturn the fact that the website the article was hosted on (and by association, the article itself) seems a little sketch (at least to me). A significant portion of the articles on the site were provided by one person, the site hasn't had a new postings in over a year, and it's parent site hercar.com.au doesn't seem to exist anymore or is having massive technical difficulties. I understand what murcod meant when he quoted this article in the Fuel economy and iAWD - let the fun begin! thread:

While I was looking for an official Suzuki PR statement on Tony Devers lecture on AWD, I found this article written for Carpoint by Jeremy Bass on the Kizashi AU website. The interesting tidbit from this article is:
Unlike the [Subaru] Liberty’s full-time AWD, [the Kizashi Sport AWD's has] a part-time system, switchable on the hoof between FWD and AWD via a button on the driver’s right. That activates an electromagnetic coupling in the transfer case up front, connected to the rear diff by a three-link prop shaft. On the go in AWD, it defaults to FWD until it detects slip, at which point it starts shifting torque rearward – up to 100 per cent if it feels the need.

For maximum traction on all but the softest take-offs – anywhere over 10km/h or 10 per cent throttle – the AWD system makes the most of the 2.4-litre four’s 131kW and 230Nm by defaulting to a 50:50 split between front and rear axles until it hits its stride.
This is the first time I've seen it mentioned ANYWHERE, that more than 50% of the power will get shifted to the rear axle in the Kizashi AWD system. It's hard for me to tell if Jeremy is implying that the power only gets shifted when slippage is detected at launch, or if he meant when the highly advanced iAWD program that Tony Devers described detects ambient conditions based on telemetry, road conditions, and driver inputs and adjusts power dynamically.

Now I don't know where Jeremy got this info, but it would be in line with my findings that in situations of especially low traction, like trying to drift in 2-3 inches of snow, the AWD will feel the need to push more power to the rear tires, not just equal power. I just wish I had better measurements than observing the amount of snow buildup in my wheel wells after I drift in the snow for a few days. As for the alignment, the issue is probably less with the alignment, and more that I like to drive like a madman on public roads. I guess what I meant by "power oversteer" earlier was drifting a Kizashi without the handbrake. If I time it right, I can get the rear axle to drift a little bit on dry asphalt after stomping on the accelerator. It's hard, but I've done it a few times. I have an SE, which leads me to believe the "Sport AWD" is on all American Kizashi AWD models, even though all the AWD systems on Kizashies I've seen have been called "iAWD".

I'm still hunting around for something that calls the AWD system on an American Kizashi "Sport AWD" or something of the likes, in the mean time, it looks like I have a lot of research to do on the suzuki.com.au website. There are a lot more promo articles for the Kizashi in Australia. I'll probably crack open the Owner's Manual when I get home from stuffing my face for Thanksgiving too. I haven't looked in it for a while, and maybe it'll have something to say about the AWD system that I might have overlooked.

Happy Thanksgiving everybody!

Good find; those are the only torque split numbers I've seen that are specific to the Kizashi's iAWD (which is different from the SX4's as far as I know). I assume they are accurate enough to be posted to Suzuki AU's official site.

So based on what we've found, it seems like that iAWD is 50:50 for spirited starts, is mostly FWD for constant speed driving, and it can shift up to 100% to the rear if needed.

gotten their Kizashi into something that feels like a power oversteer-like situation
Why yes, yes I have.
And quite regularly, I might add :mrgreen:


Gotta have balls, 'cause its grip level is already high (and you gotta be sure no one like yourself is coming the other way.....) :drive:

Looking ahead is definitely a must. I almost got in a head on collision earlier this year because a guy was going the wrong way down a one way road. :shock:

I took Azumi around a few hairpin turns by my house for the first time since putting on the Michelin's, and going around the first turn I felt like I was going to fling out of the seat because of the lateral G-forces I was pulling. :D I never had that problem with the OEM Dunlops. :lol:

So far, I'm very pleased with the Michelin Pilot Sport A/S 3's that I got. Now I just wish it would stay above 60 F (16 C) so that way I could keep enjoying them.

So here's my experience on the awd system on our 2011 sls sport.

In the dry:
Haven't pushed it hard enough to really, really know since the RE760s grip so much to begin with. But when I take a city 90 degree turn hard and get on the gas past or near the apex, I can feel something in the rear keeping the car planted vs understeering.

In the snow (with and without snow tires):
It understeers big time if you're headed towards an object and the front tires don't have grip. Don't expect the rears, even if on solid dry pavement, to come to your aid. An owner found this out the hard way hitting their Kizashi into something twice in the same day last winter.

That being said, if I'm standing still or moving slowly (haven't tried this at speed) and turn while blipping the throttle, I can get the rear to swing out and help me point the front of the car. This is with snow tires though. I don't think the dunlops would have done this at all.

My impressions is that a fwd Kizashi would perform more like any other fwd car, especially in snow. I know for sure the awd system constantly works, even in fwd mode as when I got stuck once last year, I tried it both way and saw the rear tires spinning either way.
