At this moment, the 2007 GMC Sierra Denali is the most powerful pickup in regular production that money can buy.


Dodge let the insane Ram SRT-10 fade away last year, Ford hasn't built the beloved F-150 Lightning since 2003 and the newly muscular Toyota Tundra is more than 20 horsepower behind. In fact the only open-bed contraption that matches the Sierra Denali pony-for-pony is the Cadillac Escalade EXT, which shares GM's 403-horsepower, 6.2-liter OHV V8 and six-speed automatic transmission.

But the short-bed Escalade EXT with its coil-spring live axle might as well be a wimpy sport-utility, while the GMC Sierra Denali has a separate 5-foot-9-inch cargo bed behind its four-door crew cab, plus a pair of beefy leaf springs supporting its rear axle. And while the Cadillac is rated for just a 1,362-pound payload and can tow only 7,600 pounds, the Sierra Denali can handle up to 1,719 pounds and tow 8,500 pounds.

The 2007 GMC Sierra Denali is GM's top-of-the-line luxury pickup, but it emphasizes the truck part of the equation as much as the luxury part. It's for well-heeled buyers with an indulgent sense of comfort and convenience who nevertheless insist that a truck retain its ability to do hard physical labor.

Think of it as the perfect truck for the contractor who actually loves his job and happens to have hit the Lotto. And just bought a boat.

More power(premium gas), but slower than the heavier Tundra that uses regular gas.

"But the GMC Sierra Denali is not the quickest truck on the market. That title is held by the new Toyota Tundra with its 381-hp, 5.7-liter V8. In our testing, the four-wheel-drive Tundra Double Cab pounds to 60 mph in just 6.3 seconds and runs the quarter-mile in 14.8 seconds at 93.7 mph, even though it weighs 328 pounds more than the Sierra Denali.

Sometimes power isn't enough to guarantee dominance. Or maybe either GMC or Toyota or both are wrong about the power numbers they're publishing."

More or less the same. I remember Car & Driver got 6.2 seconds for the Yukon Denali, and I think 6.3 for the Escalade. Isn't the Sierra Denali lighter than the Yukon Denali?

That actually looks very... good. Elegant, not overdone. Good job, GM.
