INFINITI Q40 Models/Series Timeline, Specifications & Photos

The Q40 was designed to replace the old G37 that was already dated for the time.

The Q40 was a four-door midsize luxury sedan that offered seating for five. It was only available with a single trim level that included 17-inch alloys, heated mirrors, keyless ignition and entry, dual-zone automatic climate control, automatic xenon headlights, cruise control, heated 8-way power front seats, Bluetooth connectivity, a rearview camera, leather upholstery and a 6-speaker audio system.

To enhance the experience, Infiniti offered the Navigation Plus package that added, of course, a navigation system, voice control, an upgraded 10-speaker premium audio system, traffic reporting and Bluetooth streaming audio. As a stand alone option, a sunroof was also available.

Compared to the rivals on the market, the Q40 was not available with much technology and features, keeping it pretty simple.

The Q40 was driven by a 3.7-liter V6 engine with 328 hp and 269 pound-feet of torque. The engine was mated with a 7-speed automatic transmission and a rear-wheel-drive system was standard. An all-wheel-drive system was also available.

Safety wise, the Q40 featured antilock brakes, stability and traction control, front side airbags and side curtain airbags. A “Snow Mode” was available for the all-wheel-drive system and was designed to control the throttle response on slippery surfaces.
