Compare the2023 Audi TTVS 2023 Porsche 718 Boxster

The TT has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The 718 Boxster doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

The TT has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The 718 Boxster doesn’t offer all-wheel drive.

The TT has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the 718 Boxster’s blind spot costs extra.

Both the TT and the 718 Boxster have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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.

The Audi TT’s engines use a cast iron block for durability, while the 718 Boxster’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

The 718 Boxster’s redline is at 7500 to 8000 RPM, which causes more engine wear, and a greater chance of a catastrophic engine failure. The TT has a 6300 to 6500 RPM redline.

On the EPA test cycle the TT gets better mileage than the 718 Boxster:

To lower fuel costs and make buying fuel easier, the Audi TT uses regular unleaded gasoline (premium recommended for maximum performance). The 718 Boxster requires premium, which can cost on average about 82.8 cents more per gallon.

The TT 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 718 Boxster doesn’t offer a cap-less fueling system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi TT higher (3 to 7 out of 10) than the Porsche 718 Boxster (1 to 5). This means the TT produces up to 47 pounds less smog-producing pollutants than the 718 Boxster every 15,000 miles.

The Audi TT comes standard with an automatic transmission, for driver comfort, especially in the city. Automatic costs extra on the 718 Boxster.

All wheel drive, available in the TT, provides the best traction for acceleration in wet, dry, and icy conditions. In corners, all wheel drive allows both outside wheels to provide power, balancing the car. This allows for better handling. The Porsche 718 Boxster is not available with all wheel drive.

For better traction, the TT has larger standard tires than the 718 Boxster (245/40R18 vs. 235/45R18). The TT’s optional tires are larger than the largest tires available on the 718 Boxster (255/30R20 vs. 245/35R20).

The TT 45 TSFI’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the 718 Boxster’s standard 45 series tires. The TT’s optional tires have a lower 30 series profile than the 718 Spyder’s 35 series front tires.

The TT has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the 718 Boxster; it requires you to depend on roadside assistance and your vehicle will have to be towed.

For a smoother ride and more stable handling, the TT’s wheelbase is 1.2 inches longer than on the 718 Boxster (98.6 inches vs. 97.4 inches).

For better handling and stability, the track (width between the wheels) on the TT is 1.9 inches wider in the front and .7 inches wider in the rear than the average track on the 718 Boxster.

The TT is 7.4 inches shorter than the 718 Boxster, making the TT easier to handle, maneuver and park in tight spaces.

If the windows are left open on the TT the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the 718 Boxster can only operate the windows from inside the vehicle, with the ignition on.

The TT’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 718 Boxster’s cruise control switches are unlit, making them difficult to find at night and operate safely.

Heated windshield washer nozzles are standard on the TT to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The 718 Boxster doesn’t offer heated windshield washer nozzles.

The TT’s LED headlights produce a white, bright light using less electricity than the 718 Boxster’s standard xenon high intensity discharge (HID) headlights. HID headlights can be slow to reach full brightness or power cycle, causing issues when flashing them to signal other vehicles; LED headlights light instantly. LED lights also last about three to four times as long.

The TT’s sun-visors swivel front-to-side to block glare from the side windows. The 718 Boxster’s visors are fixed into the windshield header.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Audi TT has a standard wireless phone charging system (Qi) in the center console. The 718 Boxster doesn’t offer wireless personal charging.
