Over 200 people are killed each year when backed over by motor vehicles. The Supra offers optional Emergency Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The 718 Cayman doesn’t offer backup collision prevention brakes.

The Supra’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The 718 Cayman doesn’t offer a lane departure warning system.

To help make backing safer, the Supra’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The 718 Cayman doesn’t offer a cross-path warning system.

The Supra’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The 718 Cayman doesn’t offer a driver alert monitor.

Both the Supra and the 718 Cayman have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available blind spot warning systems and rear parking sensors.

Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the 718 Cayman ends after only 4 years or 50,000 miles.

Toyota pays for scheduled maintenance on the Supra for 1 year and 15000 miles longer than Porsche pays for maintenance for the 718 Cayman (2/25000 vs. 1/10,000).

There are almost 7 times as many Toyota dealers as there are Porsche dealers, which makes it much easier should you ever need service under the Supra’s warranty.

An eight-speed automatic is standard on the Toyota Supra, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the 718 Cayman.

Tires and Wheels

For better traction, the Supra has larger tires than the 718 Cayman (F:255/35R19 & R:275/35R19 vs. F:235/45R18 & R:265/45R18). The Supra’s front tires are larger than the largest tires available on the 718 Cayman (255/35R19 vs. 245/35R20).

The Supra’s tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the 718 Cayman’s standard 45 series tires.

For better ride, handling and brake cooling the Supra has standard 19-inch wheels. Smaller 18-inch wheels are standard on the 718 Cayman.

For better handling and stability, the track (width between the wheels) on the Supra is 3 inches wider in the front and 2.2 inches wider in the rear than the average track on the 718 Cayman.

The Supra’s front to rear weight distribution is more even (50% to 50%) than the 718 Cayman’s (44.7% to 55.3%). This gives the Supra more stable handling and braking.

The Supra offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The 718 Cayman doesn’t offer a remote starting system.

The Supra 3.0 Premium/Launch Edition has a standard heads-up display that projects speed readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The 718 Cayman doesn’t offer a heads-up display.

If the windows are left open on the Supra 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 also lower the windows the same way. The driver of the 718 Cayman can only operate the windows from inside the vehicle, with the ignition on.

The Supra’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The 718 Cayman’s standard manually variable intermittent wipers have to be constantly adjusted.

The Supra has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning costs extra on the 718 Cayman.
