Safety Comparison

The TT has all wheel drive to maximize traction under poor conditions, especially in ice and snow. The G37 Convertible doesn’t offer all wheel drive.

The Audi TT offers Daytime Running Lights to help keep it more visible under all conditions. Canadian government studies show that driving with lights during the day reduces accidents by 11% by making vehicles more conspicuous. The G37 Convertible doesn’t offer Daytime Running Lights.

Compared to metal, the TT’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Infiniti G37 Convertible has a metal gas tank.

Both the TT and the G37 Convertible have standard driver and passenger frontal airbags, front side-impact airbags, head airbags, front seatbelt pretensioners, four wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

Warranty Comparison

The TT’s corrosion warranty is 5 years longer than the G37 Convertible’s (12 vs. 7 years).

Audi pays for scheduled maintenance on the TT for 1 year and 5000 miles. Audi will pay for oil changes, tire rotation, lubrication and any other scheduled maintenance. Infiniti doesn’t pay scheduled maintenance for the G37 Convertible.

There are over 66 percent more Audi dealers than there are Infiniti dealers, which makes it much easier to get service under the TT’s warranty.

Reliability Comparison

The Audi TT’s engines use a cast iron block for durability, while the G37 Convertible’s engine uses an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

The battery on the TT is in the trunk, which protects it from hot underhood temperatures which can degrade battery life. By keeping the TT’s battery 20 to 30 degrees cooler, its life is increased by years. The G37 Convertible’s battery is in the hot engine compartment.

Tires and Wheels Comparison

For better traction, the TT has larger standard tires than the G37 Convertible (245/40R18 vs. 225/50R18). The TT’s optional tires are larger than the largest tires available on the G37 Convertible (255/35R19 vs. 225/50R18).

The TT’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 G37 Convertible’s standard 50 series front and 45 series rear tires. The TT’s optional tires have a lower 35 series profile than the G37 Convertible’s optional 45 series front and 40 series rear tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires optional on the TT can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The G37 Convertible doesn’t offer run-flat tires.

Suspension and Handling Comparison

The TT has standard front gas-charged shocks for better control over choppy roads. The G37 Convertible’s suspension doesn’t offer gas-charged shocks.

The TT offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The G37 Convertible’s suspension doesn’t offer adjustable shock absorbers.

The TT’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The G37 Convertible doesn’t offer drift compensation steering.

The TTS Roadster handles at .94 G’s, while the G37 Convertible pulls only .87 G’s of cornering force in a Motor Trend skidpad test.

The TTS Roadster executes Motor Trend’s “Figure Eight” maneuver 1.1 seconds quicker than the G37 Convertible (25.2 seconds @ .74 average G’s vs. 26.3 seconds @ .69 average G’s).

Chassis Comparison

The Audi TT may be more efficient, handle and accelerate better because it weighs about 700 to 950 pounds less than the Infiniti G37 Convertible.

The TT is 1 foot, 6.8 inches shorter than the G37 Convertible, making the TT easier to handle, maneuver and park in tight spaces.

Passenger Space Comparison

Because it has more passenger and cargo room, the TT is rated a Subcompact car by the EPA, while the G37 Convertible is rated a Minicompact.

Cargo Capacity Comparison

The TT Roadster has a much larger trunk than the G37 Convertible with its top down (8.8 vs. 2 cubic feet).

A low lift-over trunk design makes loading and unloading the TT easier. The TT’s trunk lift-over height is 31.1 inches, while the G37 Convertible’s liftover is 32.2 inches.

Ergonomics Comparison

The TT has a lever hand brake in the console, easy to use while keeping both feet free and not impeding entry and exit. The G37 Convertible’s foot pedal parking brake is not handy to use as a hill holding device with a manual transmission.

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 G37 Convertible doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The TT offers available headlight washers to keep headlight output high. The G37 Convertible doesn’t offer headlight washers.
