Crossover SUVs, even the largest ones, simply don't have the same measure of appeal as the unibody models. The big truck-platform vehicles generally have better towing ability, more spacious cargo areas, and more off-road capability. Yes, they do suffer a bit when it comes to fuel efficiency, but many buyers will live with that so long as they have a powerful SUV that can haul the entire family around town or around the country with plenty of horsepower to spare. Two top-selling models in this vehicle class are the INFINITI QX80 and the Chevrolet Tahoe.

The 2018 INFINITI QX80 is a luxurious, three-row SUV that boasts a great combination of interior amenities, off-road capability, and excellent use of cargo space. The Chevrolet Tahoe has been a popular model for years, but it's beginning to show its age. Its interior is not as appealing as the QX80 cabin, and it doesn't provide much excitement in terms of driving experience. Below, the comparisons between the two models is further explored.

Driving Experience

Both the Base and Limited trims of the 2918 INFINITI QX80 are equipped with a powerful 5.6L V8 rated at 400 horsepower. The Base trim can be purchased with either rear- or all-wheel drive, and the Limited trim is all-wheel drive only. This is a 6,000-lb truck-based SUV, but the engine is more than capable of getting it up to freeway speed with ease. Acceleration from a full stop to 60 mph takes just 6.3 seconds, remarkable for any large three-row passenger vehicle. The self-leveling hydraulic suspension really helps out when it comes to taking high-speed turns, and the stability control is always activated. The 2018 Chevrolet Tahoe also has plenty of V8 power, but the throttle tuning is somewhat sluggish. The aging rear suspension design means plenty of bumpiness over uneven road surfaces.

Interior Refinements

The first- and second-row seating areas of the 2018 INFINITI QX80 are cavernous, offering more headroom and legroom than any other SUV in this segment. Even though the pillars are thick, there's so much glass that outward visibility isn't compromised in the slightest. Cargo space is more than adequate. Standard features on the Base trim include automatic tri-zone climate control, leather upholstery, an eight-way power-adjustable and heated driver's seat, a six-way power front-passenger seat, and a power-adjustable heated steering wheel. High-tech amenities include a 13-speaker stereo, Bluetooth, an 8-inch screen display, navigation, and satellite radio.

The 2018 Chevrolet Tahoe is large on the inside, but the high level of the floor restricts legroom. The base LS trim comes with tri-zone climate control and a 10-way power-adjustable driver's seat, but the stereo system is rather plain and includes only six speakers. Hard plastics abound inside the cabin, and the base trim doesn't have any leather surfaces.


The big V8 engine on the 2018 INFINITI QX80 can handle a full load of passengers and cargo and still pull a lot of weight. A total of 8,500 pounds can be towed with ease. If second-row bench seating is chosen, the center console is taken away, and this vastly increases cargo capacity. This is also a very good off-road vehicle. The high ground clearance and exceptional suspension ranks this model high above the competition. The 2018 Tahoe can tow almost as much weight as the QX80, but there's a slight loss of driver control. Cargo space is dismal considering the size of this SUV.
