The R8 V10 Performance’s standard fuel tank has 2.4 gallons more fuel capacity than the 911 RWD’s standard fuel tank (19.3 vs. 16.9 gallons), for longer range between fill-ups.

The R8 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.

The R8’s standard tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the 911’s standard 40 series front tires. The R8’s optional tires have a lower 30 series profile than the 911’s optional 35 series front tires.

If the windows are left open on the R8 the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. The driver of the 911 can only operate the windows from inside the vehicle, with the ignition on.

Audi Advanced Key standard on the R8 allows you to unlock the driver’s door, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Porsche 911’s available Porsche Entry and Drive doesn’t unlock the trunk.
