For the near future, GM will have the monopoly on Quadrasteer, but Delphi insiders say that it will be turning up on two other pickup models in due course. Since Ford has essentially taken a pass on the technology for the new F-Series (they saw how slowly it was selling for GM and decided it wasn't worth the effort), that only leaves the Nissan Titan and the next version of the Toyota Tundra. No one at either company will comment, of course, but what other large pickups are there?
Not always. The Suburban with QuadraSteer does not have larger fenders, or intrusive wheel wells, according to what I have read from owner's comments.Albert1234 said:But the downside is larger rear fenders and wheelwells that intrude into the bed. And, the system is expensive.
Are you sure you don't own stock in a tire manufacturer?! This sounds like a formula for excessive wear on expensive tires.Albert1234 said:4 wheel steering using 4 wheels that tilt is a good idea but I wonder if it is the only way to accomplish the task.
GM promotes their Quadrasteer by saying it allows easier parking at low speeds, and easier towing at high speeds. But the downside is larger rear fenders and wheelwells that intrude into the bed. And, the system is expensive.
I'm mainly after easier parking. I don't really care about easier towing. Couldn't Nissan reprogram their active brake limited slip and vehicle dynamic control system to completely lock one rear wheel while allowing the other to spin (at low speeds only, and when the driver activates a control). Then the rear of the vehicle would slide sideways (like a skid steer bobcat). The front of the vehicle would turn the normal way (with tilting wheels).
You might not be able to turn both ends of the vehicle at the same time (as you can do with Quadrasteer), but you could selectively turn either the front or the rear.
Sounds like a good way to flat spot the tires.Albert1234 said:I'm mainly after easier parking. I don't really care about easier towing.

No it doesn't Nissan has A nice link showing a Chevy with Quad steering pulling 8900 lbs..of course the Titan wins, it the Quad steering didn't hurt the towing ability.SarkaZm said:Doesn't this mean a decrease in towing capacity? I don't think I would give up capacity for manuverabilty. MHO.
Have you ever taken a RIDE in a Quadrasteer Chevy? Bumpity-Bumpity-Bumpity...rougher than the 2-wheel steer setup.Foo said:No it doesn't Nissan has A nice link showing a Chevy with Quad steering pulling 8900 lbs..of course the Titan wins, it the Quad steering didn't hurt the towing ability.

I totally agree! Quadrasteer addresses 1 of the 2 main shortcomings of "full size" pickups, poor maneuverability in tight situations. I also hope it is priced more reasonably, like under $1000. The other shortcoming of "full size" pickups is poor mileage, but that should be solved in the near future by diesel engines and hybrid drivetrains. Nissan is way behind Toyota and Honda on hybrid technology, so I expect to see a diesel in a Titan rather than a gas-electric hybrid powertrain.Derodeo said:This is exciting news because Quadrasteer is the one GM truck feature which is truly useful and that no one else has. If it wasn't so expensive and marketed so poorly by GM, I think it would be far more popular today. If Nissan would have Quadrasteer as an option for the 2005 model year, I'd buy it for sure. If you ever driven a vehicle with it, I think you'd be sold.
That is because of the springs and shocks, and not because of the steerable rear axle.Half Shovel said:Have you ever taken a RIDE in a Quadrasteer Chevy? Bumpity-Bumpity-Bumpity...rougher than the 2-wheel steer setup.
Ah but additional weight may be a factor as well. With more weight Chevy may have deemed it necessary to install stiffer springs...creating a rougher riding truck.outahere said:That is because of the springs and shocks, and not because of the steerable rear axle.
The springs are stiffer because Quadrasteer is only offered on the 3/4 ton Chevy pickup, and not on the half ton truck. If QS were available on the 1/2 ton Chevy, I see no reason why it should adversely affect the ride.dman said:Ah but additional weight may be a factor as well.

Do you buy your vehicles without A/C, power steering, automatic transmission, limited slip differential, alarm system, audio system, power windows, or air bags? After all, these things make a vehicle more complicated and are susceptible to future problems. :thedevil:dman said:............ but I always feel that less complicated and few parts mean less can go wrong with your vehicle and cheaper long term ownership.
