Quote »Raw numbers at the test track confirmed our gut feelings; the 0-to-60 sprint took just 7.3 seconds and the quarter-mile was unreeled in only 15.7 seconds. Although there's plenty of power on tap right off idle, our test driver noted that there was a subtle increase in thrust once the tach's needle eclipsed 4,000 rpm. If you want to have the quickest big luxury 'ute in town, you've found your ride. And if you want one of the hardest-working 'utes in town then, yep, this is still the one to pick. With a towing capacity of nearly 9,000 pounds (8,900 to be exact), the QX56 probably has more capacity than 90 percent of its owners will ever need. At least that would be the case here in L.A., where the typical payload consists of a cell phone and a Starbuck's grande latte. For those who care, we averaged 13.6 miles per gallon in mixed driving, against EPA estimates of 13 city and 18 highway.
When it came to hauling this big boy down from speed, we found the brakes were up to the task. At the track, our first attempt was the best, with an impressive 132-foot stopping distance from 60 mph. The second and third stops were both 140 feet, indicating that some fade took place after the initial test but got no worse on the third instance. Although our test pilot felt the pedal get a bit mushy under maximum effort braking (enough to call the antilock system into play), on the street the binders inspired confidence with a firm pedal feel and lack of excess body movement.[/quote]^Pretty damn impressive. The 1990 Q45 needs 147ft to come to a stop from 60, the mammoth QX beats it by 7 feet. Anyone have performance numbers for the Escalade and Navigator?
