The M4 has standard City Collision Mitigation, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Corvette doesn't offer collision warning or crash mitigation brakes.

The M4’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The Corvette doesn’t offer a lane departure warning system.

The M4 offers an optional Side and Top View Cameras to allow the driver to see objects all around the vehicle on a screen. The Corvette only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

Both the M4 and the Corvette have standard driver and passenger frontal airbags, front side-impact airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available blind spot warning systems.

For smoother operation, better efficiency and fewer moving parts, the engines in the M4 have an overhead cam design, rather than the old pushrod design of the engines in the Corvette.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that BMW vehicles are more reliable than Chevrolet vehicles. Consumer Reports ranks BMW 15 places higher in reliability than Chevrolet.

The M4 offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The Corvette doesn’t offer ceramic brake rotors.

Tires and Wheels

For better traction, the M4 has larger front standard tires than the Corvette (255/40R18 vs. 245/35R19). The M4’s optional front tires are larger than the largest tires available on the Corvette (265/30R20 vs. 245/35R19).

The M4’s optional tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the Corvette’s 35 series front tires.

For better ride, handling and brake cooling the M4 offers optional 20-inch wheels. The Corvette’s largest wheels are only 19-inches in the front and 20-inches in the rear.

For a smoother ride and more stable handling, the M4’s wheelbase is 3.5 inches longer than on the Corvette (110.7 inches vs. 107.2 inches).

The M4’s front to rear weight distribution is more even (48.1% to 51.9%) than the Corvette’s (40% to 60%). This gives the M4 more stable handling and braking.

To make loading groceries and cargo easier when your hands are full, the M4’s trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The Corvette doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

The M4’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 Corvette’s manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the M4 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Corvette doesn’t offer heated windshield washer nozzles.

While driving with high beams on, sensitive light sensors available for the M4 detect other vehicles which could be blinded and automatically switch to low beams. The Corvette doesn’t offer automatic dimming high beams.

The M4’s optional Parking Assistant can parallel park by itself, with the driver only controlling speed with the brake pedal. The Corvette doesn’t offer an automated parking system.
