An engine control system that can shut down half of the engine’s cylinders helps improve the TLX V6’s fuel efficiency. The A6 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 A6 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 A6 doesn’t offer a cap-less fueling system.
