An engine control system that can shut down some of the engine’s cylinders helps improve the CT5-V’s fuel efficiency. The M8 doesn’t offer a system that can shut down part of the engine.

The CT5-V 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.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the CT5-V can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The M8 doesn’t offer run-flat tires.
