The Roma has 4.5 gallons more fuel capacity than the 911’s standard fuel tank (21.1 vs. 16.6 gallons), for longer range between fill-ups.
The Roma 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 911 doesn’t offer a cap-less fueling system.

Tires and Wheels
For better traction, the Roma has larger front tires than the 911 (245/35R20 vs. 235/40R19).
The Roma’s tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the 911 Dakar’s standard 45 series front and 40 series rear tires.
For better ride, handling and brake cooling the Roma has standard 20-inch wheels. Smaller 19-inch front wheels are standard on the 911.
Suspension and Handling
For a smoother ride and more stable handling, the Roma’s wheelbase is 8.6 inches longer than on the 911 (105.1 inches vs. 96.5 inches). The Roma’s wheelbase is 8.4 inches longer than on the 911 GT3 (105.1 inches vs. 96.7 inches).
For better handling and stability, the track (width between the wheels) on the Roma is 2.2 inches wider in the front and 4.5 inches wider in the rear than the average track on the 911.
Passenger Space
Because it has more passenger and cargo room, the EPA rates the Roma Coupe a Subcompact car, while the 911 Coupe is rated a Minicompact.
The Roma Coupe has 7 cubic feet more passenger volume than the 911 (80 vs. 73).
Cargo Capacity
The Roma Coupe has a much larger trunk than the 911 Coupe with its rear seat up (10.3 vs. 4.8 cubic feet).
The Roma has a much larger trunk with its top down than the 911 Cabriolet with its top down (6 vs. 4.8 cubic feet).
Ergonomics
The Roma’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. An easy entry system costs extra on the 911.
If the windows are left open on the Roma the driver can close them all from a distance using the remote. On a hot day the driver can also lower the windows the same way. The driver of the 911 can only operate the windows from inside the vehicle, with the ignition on.
The Roma has standard Keyless Entry and Ignition that allows you to unlock the doors from either outside door handle, open the trunk, and start the engine, all without removing the key from the pocket or purse. The 911 GT3 doesn’t offer Comfort Access.
The Roma’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The 911’s cruise control switches are unlit, making them difficult to find at night and operate safely.
