Overview

The 2018 Infiniti Q70 Sedan is a midsize sedan offered in 2 trims with a base MSRP of $50,300. For that price, it mainly competes with the Mercedes-Benz E-Class, the BMW 5 Series, and the Audi A6. That said, the 2018 Infiniti Q70 Sedan offers 2 engine options. The base engine is a 3.7L V6 engine capable of making 330 horsepower and 270 lb-ft of torque. If more power is required, there is also a 420 horsepower-making 5.6L V6 engine. Both engines are mated to a 7-speed automatic transmission. The Q70 sedan reaches 60 mph from zero in 7.4 seconds on its base engine, which gets pumped up to 5.2 seconds with the 5.6L V8. Depending on the powertrain, the Q70 Sedan can manage a combined fuel economy between 18 and 20 mpg. While we're on the topic of choices, the 7 striking colors the Q70 comes in really pull you towards itself.

Buying Advice

Our recommendation is the 5.6 Luxe trim, which comes with a V8 engine. Furthermore, it offers a heated steering wheel, parking sensors, a heated steering wheel, a top-down parking camera system, leather upholstery, an 8-inch touchscreen, and more. Infiniti also offers 6 inches of extended wheelbase version with both powertrain options.
