The Stinger 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 CT4; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some tire options on the CT4 don’t have a run-flat feature, either.

The Stinger offers an available 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 CT4’s suspension doesn’t offer adjustable shock absorbers.

The Stinger uses gas struts to support the hood for easier service access. The CT4 uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

The Stinger has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank. The CT4 doesn’t offer a locking fuel door.

This allows the driver to concentrate on driving without constantly adjusting the wipers. The CT4’s standard manually variable intermittent wipers have to be constantly adjusted.

The CT4 Premium Luxury/Sport’s optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The Stinger GT2’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

The Stinger has standard heated front seats. Heated front seats cost extra on the CT4. The Stinger GT2 also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the CT4.
