An engine control system that can shut down some of the engine’s cylinders helps improve the XT5’s fuel efficiency. The RX doesn’t offer a system that can shut down part of the engine.

Both the XT5 and the RX have a standard automatic start/stop engine feature to stop unnecessary fuel waste and pollution at stoplights and heavy traffic. All XT5s have a standard disable switch for the system, so a driver can keep the engine from shutting off when the vehicle stops temporarily. The RX 350h/500h doesn’t offer a way to disable start/stop.

To lower fuel costs and make buying fuel easier, the Cadillac XT5 uses regular unleaded gasoline (premium recommended with the 2.0 turbo 4-cylinder engine for maximum performance). The RX 350 requires premium, which can cost on average about 84.9 cents more per gallon.

The XT5 AWD’s standard fuel tank has 3.9 gallons more fuel capacity than the RX 350’s standard fuel tank (21.7 vs. 17.8 gallons).

The XT5 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.
