Infiniti Q40

Overview: Was the Infiniti Q40 a Good Entry-Level Luxury Sedan?

The short-lived Infiniti Q40 served as an affordable alternative to the Q50 in the brand's entry-level luxury sedan lineup, being produced for the 2015 model year only. Essentially a rebadged version of the previous-generation G37, the 2015 Q40 lacked some newer features and technologies found on the Q50. However, before being discontinued, it still offered strong performance, a comfortable interior, and good overall value. Other past models include the Infiniti G25, G37, Q60, and Q70. The current Infiniti lineup consists of the Q50, QX50, QX55, QX60, and QX80.

Trims

Infiniti streamlined the Q40 lineup to two core models: a well-equipped base sedan and an AWD variant. Both came standard with leather upholstery, heated front seats, push-button ignition, and other amenities. A moonroof and navigation were the only significant options.

Comfort, Technology & Cargo

Inside, the Q40's cabin provided comfortable accommodations and quality materials. A simple layout with traditional buttons and knobs made controls easy to use. The standard 7-inch infotainment screen offers connectivity features like Bluetooth and a USB port. The trunk supplies a decent 13.5 cubic feet of cargo space.

How It Drives

Drawing from the sporty G37, the Q40 delivers engaging performance courtesy of its muscular V6 engine and responsive 7-speed automatic. Balanced handling and communicative steering make driving fun while maintaining a refined ride quality. Opting for all-wheel drive provides extra traction.

Safety

The National Highway Traffic Safety Administration did not evaluate the 2015 Infiniti Q40.

How fast is the Infiniti Q40?

With 328 horsepower from its 3.7-liter V6 engine, the Q40 could accelerate from zero to 60 mph in around 5.5 seconds—quick for this class of sedan. Sporty handling and strong braking performance added to its dynamic abilities.

All Infiniti Q40 models used a 3.7-liter V6 producing 328 horsepower and 269 lb-ft of torque. This smooth, rev-happy powerplant was shared with other Infiniti vehicles like the Q60 coupe and QX50 crossover.

When did Infiniti stop making the Q40?

The Q40 was only offered for the 2015 model year as Infiniti transitioned from the G37 to the new Q50 sedan. By limiting Q40 availability, Infiniti was able to sell the remaining G37 inventory to budget-minded shoppers before fully moving to the Q50 after that.
