The Infiniti Q70 arrives in 2015 with redesigned front and rear sections, and there’s a version with an extended wheelbase. These sedans have a naturally-aspirated engine and all-wheel drive. The factory-standard engine is a 3.7L 300-hp V6, but there’s also a more powerful 5.6L 416-hp V8. The Q70 hybrid generates a total horsepower of 360. All engines are associated with a seven-speed automatic transmission.
