Regardless of its engine, the Altima’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) Infiniti only offers an automatic engine start/stop system on the Q50 2.0t.

To lower fuel costs and make buying fuel easier, the Nissan Altima uses regular unleaded gasoline (premium recommended with the 2.0 turbo 4 cyl. engine for maximum performance). The Q50 requires premium, which can cost 20 to 55 cents more per gallon.

The Nissan Altima may be more efficient, handle and accelerate better because it weighs about 450 to 550 pounds less than the Infiniti Q50.

The design of the Nissan Altima amounts to more than styling. The Altima has an aerodynamic coefficient of drag of .26 Cd. That is lower than the Q50 (.26 to .29) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Altima get better fuel mileage.

The front grille of the Altima uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Q50 doesn’t offer active grille shutters.

The Altima SL/Platinum uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Q50 doesn’t offer active noise cancellation.
