You'll Like This Car If...
Opt for the big 6.2-liter V8 and the right configuration and you’ll get a class-leading 12,500-pound tow rating. The Toyota Tundra can’t match the Sierra’s horsepower and doesn’t offer upscale features like ventilated front seats or adaptive suspension.
You May Not Like This Car If...
If you’re seeking a diesel or turbocharged engine in your next half-ton pickup, the 2018 GMC Sierra is off the list. You can get a diesel in the smaller GMC Canyon, a less expensive option that nearly matches some of the Sierra’s bed and payload figures.
