On the way back from lunch today I saw a truck I've never seen before. It was a new GMC truck. The badge on the tailgate said "Sierra" and the badge on the door said "Denali". Now, I've heard of both Sierra and Denali so that was nothing new to me. What was interesting was the body style of the truck. This one looked like a half ton 4x4...although there was no badging to indicate such. However, it had rear fenders much like a dually....only they probably only stuck out about 1/3 as much....and it was SRW. It wasn't a step side pickup either....it was a regular fleetside bed with the little fender flares like I said above. Driving behind it I'd swear that the rear wheel base was wider than the front wheel base. Also....it had clearance lights on the fenders, the roof and the tailgate just like a dually would have.

Anyone seen these before and know anything about them? It was kind of cool.....I mean, for a GM product and all.

Nope....that's not it. This wasn't actually a dually....and it looked like it had just come off the lot (still had paper tags).

 

That would be the quadrasteer.

The rear axle turns, to help with manuevering. Interesting concept.

The rear axle is powered by elctric/hydraulic rams and the they are controlled by the computer, sensing road speed and how much the front wheels are turned.

At highway speeds, the rear wheels turn WITH the front wheels making for a straight lane change. At slow speeds, the rear wheels turn opposite, making for tighter turns.
Supposedly, this makines backing and manuevering a trailer much easier.

They do carry a heavy price tag,,, in the ball park of $40K+

The all new GMC Sierra Denali. Don't think I've ever seen a truck with as many standard features as this one.



The one I saw actually looked pretty sharp.

 

Have a red s-10 4 door dually running around here. Dual hood scoop as well. Clean truck, but hillarious.

 

 

Honda did that same thing (rear wheel steer) on some of the Preludes in the early 90's.
Theys stopped that idea after several Preludes lost control on the freeway due to mechanical issues.
My boss (at that time) had one. It was a nice gold/metalic color with all the bells and whistles.
That was, until the rear steer went bad at 70mph and put that Prelude into a viscious spin.
She (my boss) was very luck that the Prelude did not contact anything in the spin out.
She got rid of that car soon after. :

I hope GM learns from history and they do not repeat the same mistakes.

On a side note,
I would think having a steering rear axle would reduce the trucks payload capicity due to the steering knuckles?
What about the dually's? How would they get around the rear steer with those?

Just wondering out loud.

I'm not sure if they offer the rear steering on the duallies....but I wouldn't want rear steering anyway. To each their own though...

 

It's another one 'o them Yuppie plastic cars...

Look it's an SUV - No it's a truck - NO it's a jeep! And all with just the flip of a plastic handle!

Yeah, I dont think they do offer it with duallies.
Ironic, its the duallies that do most of the towing and thats what the rear wheel steer is suppose to help.
Yes, to each their own.

Rich.

 

They don't offer it on the duallies and they only offer it on some of the 2500's. It's mainly on the fully decked out (read denali) packaged 1500's. You can turn the rear steer on and off as well. It's been out for a while now. Haven't heard anything bad about them. The trucks that it comes on are so expensive, I wouldn't want to use them to haul anything.

 

Its also available on Yukon/Suburbans. I believe it is about a $4000 option.

 

And a pain in the butt to put on and off a trailer :P

 

1500HD, and 2500LD only.

These trucks feature 4 doors, short bed, 8-lug axles, but only slightly better hauling capability than a true half ton.

Ryan is right about the Suburban, and Yukon XL's. The 2500 versions only.
