2011 Infiniti M56x - Short Take Road Test - Car and Driver
Stop us if youve heard this one before: Theres a rear-wheel-drive luxury sedan thats also available with all-wheel drive. Its sticker price and curb weight are slightly higher, and its performance and fuel economy are lower. The subject here is the Infiniti M56x , and true to the formula, its a lot like the rear-wheel-drive M56. Consider that a good thing. Opt to add a lower-case x to the badge of your M56, and youll leave the dealership $2500 poorer, as the base price is $60,915. Fuel economy drops from 25 mpg highway to 23, and the 16-mpg city figure is unchanged. (The difference in observed fuel economy was more pronounced, however, as we averaged 18 mpg with this M56x versus the 23 with a rear-drive M56S. ) Curb weight is up about 180 pounds, and the monster 420-hp, 5. 6-liter V-8 under the hood pushes... The M56xs braking performance, 166 feet from 70 to 0 mph, and skidpad grip, 0. 83g, are close to those of the M56S. But the M56x shows better than its rear-wheel-drive counterpart in some crucial nontest situations. We have yet to drive an M56 without the Sport package, which comes with high-performance summer tires on 20-inch rims and a rear-wheel steering system. Source: www.caranddriver.com
