Cadillac XTS – First GM Car with Capless Fueling

2013 Cadillac XTS 00878 1 300x187 Cadillac XTS – First GM Car with Capless FuelingFour years ago, Ford Motor Company was the first to introduce a new system to add gasoline to a vehicle without removing a cap, and now that system has spread to most of the Ford lineup.

Now General Motors is announcing the introduction of a better capless fueling system on the new Cadillac XTS luxury sedan. 

“This new system has advantages for both the car and the driver,” said John Hamilton, Cadillac fuel fill systems design engineer. “It helps keep hands free of dirt and fuel, paint free of scratches caused by a swinging cap, and the engine running smoothly.”

Because fuel systems must be fully sealed, a loose cap can trigger a “check engine” light and lead to service visit.

The 2013 XTS doesn’t have a traditional twist-off cap hidden behind its fuel door. Because of this, the door itself doesn’t need to accommodate a hand and was designed to be smaller and less noticeable on the XTS’ sheet metal.

Despite having no cap, the system meets all fuel system sealing regulations. When a fuel nozzle is inserted, it pushes aside a set of two doors, each locking fuel in with a rubber seal around its edge. The two doors are designed to assure the system will remain air-tight through years of ownership.

Moving beyond capped systems has further advantages for car owners. It eliminates the risk of leaving a gas station with a dangling cap, which can lead to paint damage and messy fuel dripping.

Because the XTS uses an advanced V-6 engine with direct-injection and lightweight innovations like exhaust manifolds integrated into the cylinder heads and a next-generation six-speed transmission, fuel stops will be less frequent.

We expect the capless fueling system will be a fixture on most GM vehicles in a few years.
