Both the 4C and the TT have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.


To reliably power the ignition and other systems and to recharge the battery, the 4C has a standard 160-amp alternator. The TT’s 140-amp alternator isn’t as powerful.


The 4C’s 1.8 turbo 4 cyl. produces 9 more horsepower (237 vs. 228) than the TT 45 TFSI’s standard 2.0 turbo 4 cyl.

As tested in Car and Driver the Alfa Romeo 4C is faster than the Audi TT:

Fuel Economy and Range

On the EPA test cycle the 4C gets better fuel mileage than the TT 45 TFSI (24 city/34 hwy vs. 23 city/31 hwy).

The 4C 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 TT doesn’t offer a cap-less fueling system.

Brakes and Stopping

The 4C’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the TT 45 TSFI are solid, not vented.

The 4C stops much shorter than the TT:

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the 4C is 2.8 inches wider in the front and 2.1 inches wider in the rear than the average track on the TT.

The 4C’s front to rear weight distribution is more even (41% to 59%) than the TT’s (60.7% to 39.3%). This gives the 4C more stable handling and braking.


The Alfa Romeo 4C may be more efficient, handle and accelerate better because it weighs about 700 to 900 pounds less than the Audi TT.

The 4C is 8 inches shorter than the TT, making the 4C easier to handle, maneuver and park in tight spaces.


The 4C was chosen as one of Automobile Magazine’s “All Stars” in 2015. The TT has never been an “All Star.”
