If you demand total steering compliance from a tow vehicle, along with stability and maneuverability from what's being towed, the GMC Sierra Denali with Quadrasteer is just the ticket. Developed jointly by GM and Delphi Automotive Systems, Quadrasteer (a rear-wheel-steering system for trucks) is a standard feature on the '02 Sierra Denali pickup and soon to be on other full-size GM products. By using various sensors around the vehicle, a microprocessor computes the correct rear-wheel position and actuates an electric motor to turn it accordingly.  Below 45 mph, the rear wheels can steer up to 12 (left or right). At these speeds, the rear wheels turn in the direction opposite the fronts. Above 40 mph, the rear wheels turn in the same direction as the fronts to significantly limit the pivoting a trailer feels at the hitch. Forty-five mph is a neutral zone, where the rear wheels maintain a fairly straight-ahead position even when the front wheels are turned. When in the 4WS Tow Mode (recommended for towing), the speed of the neutral zone is reduced by the microprocessor to 25 mph. Visually, rear-wheel turn appears modest, but the amount they do turn yields dramatic performance dividends. The Sierra Denali, with its Vortec 6000 V-8 and strong all-wheel-drive system, is capable of towing up to 10,000 lb. Hitching the Sierra Denali to a Holiday Rambler Alumascape travel trailer, we set out to test the setup. With the Alumascape having a dry weight of just under 5000 lb and a hitch weight of about 500 lb, we augmented our tow setup with a load distribution hitch and a sway-control device. We also added an electronic brake controller that actuates the trailer's electric brakes when the brake pedal is applied. Fully prepared, we headed up California Highway 74, which begins at sea level and climbs and winds a few thousand feet up before plunging down the backside of some rough desert mountains to Lake Elsinore below. 
The trailer tracked well, exhibiting minimum trailer sway, and, with the exception of being visible in the side mirrors, for all intents and purposes its presence was transparent to us. Powering through mountain esses and tight hairpin turns, this twosome exhibited good synergy. Returning via the Interstate, we found that transitioning from one lane to another at freeway speeds was noticeably quicker and smoother, yielding less trailer sway than when we duplicated these same maneuvers using the 2WS Mode. Standard features of the Sierra Denali include a Vortec 6000 that develops 325 hp and 370 lb-ft of torque. Standard is a full-time all-wheel-drive system that employs a viscous coupling center differential in the transfer case that senses slippage front and rear and provides torque as needed, where it's needed. All by itself, this improves towing performance, especially under slick-surface conditions. The heavy-duty Dana 60 rear axle features a 4.10:1 ratio and a 9.8-in. ring gear (standard for the 1/2-ton Sierra is an 8.6-in. gear). The transmission is GM's newly revised and strengthened four-speed automatic

REWIND: Watch the GMC Hummer EV live reveal right here

Tue, Oct 20 2020

It has been a long wait to see the GMC Hummer electric pickup truck, which was teased way back at the Super Bowl in February of this year. And that wait ends tonight at 8 p.m. eastern time when GM pulls the covers off the truck. You can see the whole reveal right here, or during the World Series on Fox or "The Voice" on NBC. For everything we know about the truck, go to our reveal post here. The truck should be impressive. GMC has previously announced it will have up to 1,000 horsepower, and it will have a variety of fun features such as removable roof panels and four-wheel steering that can move the truck sort of sideways with "Crab Mode." The GMC Hummer will also be available in pickup and SUV forms. So be sure to tune in tonight for one of the biggest (figuratively and literally) vehicle reveals of the year. And keep an eye on Autoblog for all the latest on the Hummer and other vehicles.

2015 GMC Yukon erupts into flames during Anaheim test drive [w/video]

Mon, 24 Mar 2014

A 2015 GMC Yukon burst into flames while on a test drive in Anaheim, CA on Sunday after smoke filled the cabin. Residents of the neighborhood where the driver abandoned the redesigned Yukon reported hearing a series of small explosions (likely the tires, based on the video), according to a report from KTLA and The Los Angeles Times.
No one was injured in the incident, which The Times reports occurred after a possible oil or fluid leak. As you can see in the image above, the Yukon was engulfed in flames, although the Anaheim Fire Department was able to put out the blaze in about 15 minutes.
"We're very lucky that no one got hurt, and it was in an area that... was safe," Lt. Tim Schmidt of the Anaheim Police Department told KTLA reporters. "If there was any place that was going to be safe, it would be this area. It's very open. It worked out for us."

Despite strong profits, GM still fighting flat market share

Fri, Jan 17 2014

Looking at the progress General Motors has made since it entered bankruptcy, it's easy to forget that the company still has a long way to go before it's the juggernaut it once was. A recent report from Reuters points out that, while GM is making money, it isn't making any gains in terms of US market share. Quite the opposite, really. Consider this factoid: In 1963, nearly half of the cars sold in the United States were from Chevrolet, Cadillac, Buick, GMC or Pontiac. Now, the company's US market share is stagnant at 17.9 percent. That same number is half of just Chevy's 1963 market share. This is all despite GM going on a binge replacing or updating its models. "Market share increases are not instantaneous," Mark Reuss told Reuters at the 2014 Detroit Auto Show. "We've got a lot of baggage. Don't underestimate what people though of us, or these brands, through these hardships and 30 years." The reasons for the stagnant market share are numerous. Reuters points out that retooling of factories and a focus on limiting incentives are both good things for profit, but not necessarily for market share. There's also the troubling turnover of the brand's marketing department. These issues don't change the fact that Chevrolet has lost 1.4 percent of its market share in two years, and that Cadillac - arguably GM's most improved brand overall - has lost 1.2 percent in the same period. Part of that can be blamed on GM's avoidance of fleet sales in favor of more profitable customer sales. "Our focus has really been on retail and that's where we've got the growth," said Alan Batey, GM's interim global marketing boss. "We want to grow GM and that means growing market share and profits, but it's not at all costs," Reuss said.
