Q40 Features

The INFINITI Q40 was previously called the G37, and it remains one of INFINITI’s best-selling sedans. The Q40 is a classic sports sedan, meaning it has the spaciousness and style of a four-door but its equipped with an engine that packs a pop. The Q40 is powered by a 3.7-liter V6 engine that delivers 328-horsepower. The Q50 was the replacement for the Q40, and they share several design similarities. Yet, the Q40’s roofline rises higher, before sloping to the tail-end.

Q50 Features

The INFINITI Q50 underwent a major overhaul in 2014, and this year, the 2015 features slight modifications. As it was inspired originally by the G37, the Q50 features similar styling and both the Q40 and Q50 share the same 3.7-liter V6 engine. The rear-wheel-drive Q50 accelerates 0-60 MPH in 5.3 seconds and it has received a few upgrades in terms of handling and maneuverability. One of the biggest differences between Q40 and Q50 is the interior. Both sedans are equipped with color LCD displays, but the Q50 two instead of one.

Q70 Features

The Q70 is INFINITI’s fully loaded sports sedan. Whereas the Q40 and Q50 share many similarities, the Q70 shares none. Inside, the Q70 is equipped with a dual-stack LCD screen display. Up top, there’s an 8-inch vehicle information screen with navigation and real-time weather reporting, and below is a 7-inch touchscreen for audio controls and connected apps. Features include Japanese Ash accents, leather, heated front seats, an available BOSE stereo system, and INFINITI Voice Recognition for navigation, audio and apps. The Q70’s exterior stylings share similarities with the Q40 and Q50, but the Q70 is more agile with more sculpted lines.

One of the biggest differences is the under the hood. Base RWD and AWD models are equipped with a 3.7-liter engine that receives 330 horsepower, which is very close to the engine used in the Q40 and Q50. But the Q70 is available with a supped 5.6-liter V8 that pumps the horsepower up to 420. It’s the only INFINITI sedan that’s available with the V8 configuration. Plus, the Q70 is also available as a hybrid.
