The 2013 Toyota Sequoia weighs nearly 6,000 and is powered by a huge V-8 engine. So it's not all that much of a surprise that this big rig is a guzzler.
But it's worth considering that the Sequoia can carry up to eight and tow up to 7,400 pounds. If you're using the Sequoia's full capabilities, then its official EPA rating of 13 mpg in the city and either 17 or 18 mpg on the highway might not be so horrible. Drive the Sequoia empty to work every day, though, and you might be the target of environmentalist scorn.
If you're having issues over the Sequoia's gas mileage, GM's full-size SUVs, the Chevrolet Tahoe and GMC Sierra, do offer a hybrid option, and Mercedes-Benz’s GL Class can be ordered with a clean diesel.
