Following extensive research-otherwise known as "Google"-we've determined that the world's largest tree, according to the U.S. National Park Service, is the General Sherman, a sequoia in California's Sequoia National Park.
This is a bit unfortunate, as we were hoping to help Toyota find a new name for its largest SUV, the all-new 2008 Sequoia, which is so big that keeping the Sequoia name seems slightly modest. But if the Sequoia is already the largest tree, then it looks like we, and Toyota, are stuck with it.
You already know why the second-generation Sequoia (a mild freshening in 2005 doesn't qualify as a "generation") is so big: The vehicle platform it's based on, the Tundra pickup, is huge, so it stands to reason the new Sequoia would be, too. The wheelbase, at 122.0 inches, is up 3.9 inches; length, at 205.1 inches, is up 1.2 inches. It's also an inch wider and half an inch taller. Unlike the Tundra, the Sequoia has a fully boxed frame.
The biggest news is under the hood, though. Previously, the best we could do in the Sequoia was the standard 273-hp, 4.7-liter V-8 and five-speed automatic transmission. That powertrain remains, but it's supplemented by the Tundra's beefy 381-hp, 5.7-liter V-8 with a six-speed automatic. The Sequoia can now tow a maximum of 10,000 pounds, up from 6500.
Why Two Big SUVs?
The 2008 Sequoia is offered in three basic flavors: the base SR5, the Limited-previously the premium model, now midlevel-and the absolutely loaded Platinum. The presence of the Platinum made us wonder why Toyota needed that model as well as the newly refreshed, Japanese-built Land Cruiser, and the answer is that they seem to appeal to two separate markets: Land Cruiser buyers have an average household income of $237,000; Sequoia buyers average "only" $106,000.
Toyota figures that 55 percent of 2008 Sequoia sales will be the SR5, 35 percent the Limited, and just 10 percent the Platinum. Rear- and four-wheel-drive sales should be split evenly. And Toyota has high expectations for the 5.7-liter V-8, figuring it will account for 90 percent of the product mix. One reason: It actually gets better fuel mileage than the 4.7. Neither will get kudos from the Sierra Club, though: EPA estimates for the four-wheel-drive models are 13 mpg city and 16 highway for the 4.7, and 13 and 18 for the 5.7. We averaged 12 mpg, which included some light towing.
The engines do, after all, have their work cut out for them. The four-wheel-drive Platinum we tested weighed in at a substantial 6100 pounds, about 300 pounds heavier than the rear-wheel-drive SR5. But the Platinum is no slouch: We logged a 0-to-60-mph time of 6.6 seconds and a quarter-mile time of 15.2 seconds at 92 mph. The Sequoia stops, too, thanks largely to huge 13.9-inch vented rotors up front and 13.6-inchers in the back: 70 mph to 0 took 184 feet. Not much that technology or the front-and-rear unequal-length control-arm suspension can do to help all that mass on the skidpad, as the Platinum registered a 20-inch-tire-moaning 0.73 g, inhibited by its undefeatable stability control.
