Audi SQ5 vs Toyota Sequoia: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Toyota Sequoia burns about $2,800 of fuel annually against $3,300 for the Audi SQ5. That $500 yearly gap compounds to roughly $2,500 over five years and $4,000 over eight — often more than the price difference between two trims of the same vehicle, and the single largest running-cost line item separating these two.

City versus highway split: the Toyota Sequoia is the stronger commuter at 21 mpg city, while the Audi SQ5 pulls ahead on the interstate at 28 mpg highway. If most of your driving is stop-and-go traffic the city figure is the one to weigh; for long-distance highway mileage the reverse is true, and the two vehicles effectively swap places depending on how you drive.

Powertrain choice: the Audi SQ5 is recorded with 1 distinct engine configuration (SIDI), the Toyota Sequoia with 3 (SIDI & PFI; Hybrid, 5.7, FFV). Across 20 recorded Audi SQ5 configurations and 30 for the Toyota Sequoia, the wider the engine spread the more the real-world fuel efficiency depends on which version you actually buy, so check the specific model year and drivetrain rather than the headline number.

Drivetrain and class: the Audi SQ5 is offered with All-Wheel Drive, 4-Wheel Drive, the Toyota Sequoia with Rear-Wheel Drive, Part-time 4-Wheel Drive. All-wheel drive typically costs one to two mpg combined against the same vehicle in front- or rear-wheel drive, which is worth remembering when the gap between these two is small. The EPA classes them as Small Sport Utility Vehicle 4WD and Standard Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.

Tailpipe emissions: at their cleanest configurations the Audi SQ5 emits 382 g/mile of CO2 versus 395 g/mile for the Toyota Sequoia. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
