Compare the2025 Mercedes GLC CoupeVS 2025 Alfa Romeo Tonale

For enhanced safety, the front and rear seat shoulder belts of the Mercedes GLC Coupe have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Alfa Romeo Tonale doesn’t offer pretensioners for its rear seat belts.

The GLC Coupe’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Tonale doesn’t offer pre-crash pretensioners.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the GLC Coupe are reminded to check the back seat if they opened the rear door before starting out. The Tonale doesn’t offer a back seat reminder.

The GLC Coupe has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Tonale doesn’t offer front seat center airbags.

The GLC Coupe has standard NECK-PRO front head restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the NECK-PRO front head restraints system moves the headrests forward to prevent neck and spine injuries. The Tonale doesn’t offer a whiplash protection system.

The GLC Coupe has standard Post-Collision Brake, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Tonale doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The GLC Coupe has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Tonale doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.

Both the GLC Coupe and Tonale have rear cross-traffic warning, but the GLC Coupe has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Tonale’s Rear Cross-Path Detection doesn’t automatically brake.

Both the GLC Coupe and the Tonale have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available lane departure warning systems.

The Mercedes GLC Coupe achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year.

The Tonale has not yet been evaluated by the IIHS for 2024.

For better ride, handling and brake cooling the GLC Coupe has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Tonale. The GLC Coupe’s optional 21-inch wheels are larger than the 20-inch wheels optional on the Tonale.

The GLC Coupe 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 Tonale; it requires you to depend on roadside assistance and your vehicle will have to be towed.

The GLC Coupe’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 Tonale doesn’t offer drift compensation steering.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the GLC Coupe. The Tonale doesn’t offer locking storage for small valuables.

The GLC Coupe’s standard towing capacity is much higher than the Tonale’s (3500 vs. 2000 pounds).

Optional Trailer Stability Assist on the GLC Coupe uses the Electronic Stability Program sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The Tonale doesn’t offer electronic trailer sway control.

The engine in the GLC Coupe is mounted longitudinally (North-South), instead of sideways, as in the Tonale. This makes it easier to service and maintain, because the accessory belts are in front.

Unlike the driver-only memory system optional at extra cost in the Tonale, the GLC Coupe has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The GLC Coupe’s standard easy entry and exit feature raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the Tonale.

The GLC Coupe offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Tonale doesn’t offer a heads-up display.

The GLC Coupe’s standard Keyless-Go allow you to unlock the doors from any outside door handle, open the cargo door, and start the engine, all without removing the key from the pocket or purse. Keyless-Enter-n-Go standard on the Tonale doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

Heated windshield washer fluid is standard on the GLC Coupe to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The Tonale doesn’t offer heated windshield washer fluid. Its standard heated washer nozzles will defrost the washer fluid but not the windshield.

When the GLC Coupe is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Tonale’s mirror doesn’t automatically adjust for backing.

Both the GLC Coupe and the Tonale have standard heated front seats. The GLC Coupe also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Tonale.

The GLC Coupe’s Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Tonale’s automatic parking system requires operating the brakes and transmission to safely park.
