An engine control system that can shut down half of the engine’s cylinders helps improve the TLX V6’s fuel efficiency. The Q50 doesn’t offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the Acura TLX uses regular unleaded gasoline (premium recommended for maximum performance). The Q50 requires premium, which can cost 20 to 55 cents more per gallon.

The TLX has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The Q50 doesn’t offer a cap-less fueling system.

A nine-speed automatic is standard on the Acura TLX, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the Q50.

The TLX offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Q50 doesn’t offer an SMG or a conventional manual transmission.

The TLX has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Q50 doesn’t offer vehicle monitored tire inflation.

The TLX offers an available space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Q50; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

Standard air-conditioned seats in the TLX Advance/V6 A-Spec keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The Q50 doesn’t offer air-conditioned seats.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Acura TLX offers an optional wireless phone charging system (Qi) for the front seat. The Q50 doesn’t offer wireless personal charging.
