The venerable QX70 soldiers on in its current form, and is still the sportiest SUV in Infiniti's lineup. Its 3.7-litre V6 develops 325 horsepower, sent to the ground by a seven-speed automatic transmission and an all-wheel drivetrain. The Sport version boasts a more aggressive appearance and more features, while the Limited edition puts the emphasis on luxury with open-pore wood and flaked aluminum interior trim as well as quilted leather seat upholstery.
