For enhanced safety, the front and rear seat shoulder belts of the Mercedes E-Class 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 Infiniti Q60 doesn’t offer pretensioners for its rear seat belts.

For enhanced safety, the front seat shoulder belts of the Mercedes E-Class Coupe are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Infiniti Q60 doesn’t offer height-adjustable seat belts.

The Mercedes E-Class Coupe has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Q60 doesn’t offer knee airbags.

The E-Class Coupe offers an optional Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Q60 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.

The E-Class Coupe has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. Only the Q60 Luxe/Red Sport 400 offers a blind spot warning system.

To help make backing out of a parking space safer, the E-Class Coupe has standard Rear Cross-Traffic Alert and Active Brake Assist automatically engages the brakes to help avoid a collision. Only the Q60 Luxe/Red Sport 400 offers rear cross-path warning.

The E-Class Coupe’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 Q60 doesn’t offer a driver alert monitor.

Both the E-Class Coupe and the Q60 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, collision warning systems, daytime running lights, rearview cameras, available all wheel drive and lane departure warning systems.

Warranty

There are over 89 percent more Mercedes dealers than there are Infiniti dealers, which makes it much easier should you ever need service under the E-Class Coupe’s warranty.

Reliability

To reliably power the ignition and other systems and to recharge the battery, the E-Class Coupe has a standard 180-amp alternator. The Q60’s standard 150-amp alternator and largest (Red Sport 400) 170-amp alternator aren’t as powerful.

To reliably start during all conditions and help handle large electrical loads, the E-Class Coupe has a standard 850-amp battery. The Q60’s 600-amp battery isn’t as powerful.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Mercedes vehicles are better in initial quality than Infiniti vehicles. With 15 fewer problems per 100 vehicles, JD Power ranks Mercedes higher than Infiniti.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Mercedes vehicles are more reliable than Infiniti With 33 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Mercedes higher than Infiniti.

Engine

The E-Class Coupe’s 3.0 turbo 6-cylinder hybrid produces 62 more horsepower (362 vs. 300) and 74 lbs.-ft. more torque (369 vs. 295) than the Q60’s standard 3.0 turbo V6. The E-Class Coupe’s 3.0 turbo 6-cylinder hybrid produces 19 lbs.-ft. more torque (369 vs. 350) than the Q60 Red Sport 400’s standard 3.0 turbo V6.

Fuel Economy and Range

On the EPA test cycle the E-Class Coupe gets better mileage than the Q60:

			MPG
E-Class Coupe
	RWD	3.0 turbo 6-cyl. Hybrid	23 city/30 hwy
	AWD	3.0 turbo 6-cyl. Hybrid	21 city/30 hwy
Q60
	RWD	3.0 turbo V6	19 city/28 hwy
		Red Sport 400 3.0 turbo V6	20 city/27 hwy
	AWD	3.0 turbo V6	19 city/27 hwy
		Red Sport 400 3.0 turbo V6	19 city/26 hwy

Regenerative brakes improve the E-Class Coupe’s fuel efficiency by converting inertia back into energy instead of wasting it. The Q60 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the E-Class Coupe’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The Q60 doesn’t offer an automatic engine start/stop system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes E-Class Coupe higher (6 out of 10) than the Infiniti Q60 (3). This means the E-Class Coupe produces up to 23.4 pounds less smog-producing pollutants than the Q60 every 15,000 miles.

Transmission

A nine-speed automatic is standard on the Mercedes E-Class Coupe, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the Q60.

Brakes and Stopping

For better stopping power the E-Class Coupe’s brake rotors are larger than those on the Q60:

	E-Class Coupe	Q60	Q60 Red Sport 400
Front Rotors	14.2 inches	12.6 inches	14 inches
Rear Rotors	14.2 inches	12.1 inches	13.8 inches

The E-Class Coupe stops shorter than the Q60:

	E-Class Coupe	Q60
70 to 0 MPH	156 feet	164 feet	Car and Driver
60 to 0 MPH	109 feet	110 feet	Motor Trend

Suspension and Handling

The E-Class Coupe has standard front and rear gas-charged shocks for better control over choppy roads. The Q60’s suspension doesn’t offer gas-charged shocks.

The E-Class Coupe has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The E-Class Coupe’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The Q60 doesn’t offer a load leveling suspension.

The E-Class 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 Q60 doesn’t offer drift compensation steering.

For better handling and stability, the track (width between the wheels) on the E-Class Coupe is 1.7 inches wider in the front and 1 inch wider in the rear than the average track on the Q60.

The E 450 Coupe 4MATIC handles at .90 G’s, while the Q60 Red Sport 400 AWD pulls only .88 G’s of cornering force in a Car and Driver skidpad test.

Passenger Space

The E-Class Coupe has 3.6 cubic feet more passenger volume than the Q60 (89 vs. 85.4).

The E-Class Coupe has 1.5 inches more front shoulder room, 1.9 inches more rear headroom, 3.5 inches more rear legroom and 4.9 inches more rear hip room than the Q60.

Cargo Capacity

The E-Class Coupe has a much larger trunk than the Q60 (10 vs. 8.7 cubic feet).

The E-Class Coupe’s standard folding rear seats are split to accommodate bulky cargo. The Q60’s standard single piece folding rear seat is not as flexible; long cargo and a passenger can’t share the rear seat.

To make loading and unloading groceries and cargo easier when your hands are full, the E-Class Coupe’s power trunk can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The Q60 doesn’t offer a power or hands-free opening trunk.

Servicing Ease

The E-Class Coupe has a maintenance free battery for long life without checking the battery’s water level. The Q60 doesn’t have a maintenance free battery, so the water level in the battery’s cells must be checked often to prevent damage.

Ergonomics

Unlike the driver-only memory system optional at extra cost in the Q60, the E-Class 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 E-Class Coupe’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. The Q60 doesn’t offer an easy entry system.

The E-Class 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 Q60 doesn’t offer a heads-up display.

The E-Class Coupe’s power parking brake sets with one touch and releases with one touch or automatically. The Q60’s parking brake has to be released manually.

The power windows standard on both the E-Class Coupe and the Q60 have locks to prevent small children from operating them. When the lock on the E-Class Coupe is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Q60 prevents the driver from operating the other windows just as it does the other passengers.

Keyless-Go standard on the E-Class Coupe allows you to unlock the driver’s door, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Infiniti Q60’s Infiniti Intelligent Key doesn’t unlock the trunk.

Heated windshield washer fluid is standard on the E-Class Coupe to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The Q60 doesn’t offer heated windshield washer fluid.

A power rear sunshade is optional in the E-Class Coupe to help block heat and glare for the rear passengers. The Q60 doesn’t offer a rear sunshade.

Optional air-conditioned seats in the E-Class Coupe keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Q60 doesn’t offer air-conditioned seats.

The E-Class Coupe has a standard center folding armrest for the rear passengers. A center armrest helps make rear passengers more comfortable and it can provide a boundary between children. The Q60 doesn’t offer a rear seat center armrest.

The E-Class Coupe offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Q60.

Both the E-Class Coupe and the Q60 offer rear vents. For greater rear passenger comfort, the E-Class Coupe has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Q60 doesn’t offer rear air conditioning vents, only heat vents.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes E-Class has a standard wireless phone charging system (Qi) in the center console. The Q60 doesn’t offer wireless personal charging.

The E-Class Coupe’s Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Q60 doesn’t offer an automated parking system.

Model Availability

The Mercedes E-Class comes in coupe, convertible, sedan and station wagon bodystyles; the Infiniti Q60 isn’t available as a convertible, sedan or station wagon.
