The Roma comes with a full 3-year/unlimited-mile basic warranty, which covers the entire car and includes free 24-hour roadside assistance. The 911’s 50,000-mile basic warranty expires sooner.

Ferrari pays for scheduled maintenance on the Roma for 6 years and -10,000 miles longer than Porsche pays for maintenance for the 911 (7/unlimited vs. 1/10,000).

The Roma’s 3.9 turbo V8 produces 233 more horsepower (612 vs. 379) and 230 lbs.-ft. more torque (561 vs. 331) than the 911’s standard 3.0 turbo 6-cylinder. The Roma’s 3.9 turbo V8 produces 169 more horsepower (612 vs. 443) and 171 lbs.-ft. more torque (561 vs. 390) than the 911 S’ standard 3.0 turbo 6-cylinder.

On the EPA test cycle the Roma gets better mileage than the 911 Coupe:

The Roma has 4.2 gallons more fuel capacity than the 911’s standard fuel tank (21.1 vs. 16.9 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.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Ferrari Roma higher (6 out of 10) than the Porsche 911 (3 to 5). This means the Roma produces up to 23.4 pounds less smog-producing pollutants than the 911 every 15,000 miles.

For better stopping power the Roma’s standard brake rotors are larger than those on the 911:

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.

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).

For better handling and stability, the track (width between the wheels) on the Roma is 2.4 inches wider in the front and 4.5 inches wider in the rear than the average track on the 911.

Because it has more passenger and cargo room, the EPA rates the Roma a Subcompact car, while the 911 Coupe is rated a Minicompact.

The Roma has 7 cubic feet more passenger volume than the 911 (80 vs. 73).

The Roma has a much larger trunk than the 911 Coupe with its rear seat up (10.3 vs. 4.6 cubic feet).

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.
