The Infiniti Q40 was a single-model-year vehicle in 2015, a continuation of the previous G Sedan. The Infiniti Q40 came in a single level of specification that included standard leather upholstery. In addition, a power sunroof, navigation system, and premium sound system were options. Performance-wise, the sports sedan featured a 328-hp 3.7-liter V6 engine. However, the Q40 had no stick-shift option, just a seven-speed automatic. But you could swap the standard rear-wheel drive for an all-wheel-drive system.
