Safety

For enhanced safety, the Cadillac ATS Coupe’s rear seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Infiniti Q60 doesn’t offer height adjustable seat belts.

Compared to metal, the ATS Coupe’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Infiniti Q60 has a metal gas tank.

Both the ATS Coupe and the Q60 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems, rear parking sensors and rear cross-path warning.

Warranty

Cadillac pays for the first scheduled maintenance on the ATS Coupe. Cadillac will pay for an oil change, lubrication and any other required maintenance. Infiniti doesn’t pay scheduled maintenance for the Q60.

There are over 4 times as many Cadillac dealers as there are Infiniti dealers, which makes it much easier should you ever need service under the ATS Coupe’s warranty.

Reliability

The battery on the ATS Coupe is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the ATS Coupe’s battery 20 to 30 degrees cooler, its life is increased by years. The Q60’s battery is in the hot engine compartment.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Cadillac vehicles are better in initial quality than Infiniti vehicles. J.D. Power ranks Cadillac 12th in initial quality, above the industry average. With 2 more problems per 100 vehicles, Infiniti is ranked 14th.

Engine

The ATS Coupe’s optional 3.6 DOHC V6 produces 35 more horsepower (335 vs. 300) than the Q60 3.0t’s standard 3.0 turbo V6.

Fuel Economy and Range

On the EPA test cycle the ATS Coupe RWD V6 gets better fuel mileage than the Q60 3.0t (19 city/29 hwy vs. 19 city/27 hwy).

An engine control system that can shut down half of the engine’s cylinders helps improve the ATS Coupe V6’s fuel efficiency. The Q60 doesn’t offer a system that can shut down part of the engine.

Regardless of its engine, the ATS Coupe’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) Infiniti only offers an automatic engine start/stop system on the Q60 2.0t.

To lower fuel costs and make buying fuel easier, the Cadillac ATS Coupe uses regular unleaded gasoline (premium recommended with the 2.0 turbo 4 cyl. engine for maximum performance). The Q60 requires premium, which can cost 20 to 55 cents more per gallon.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Cadillac ATS Coupe higher (5 out of 10) than the Infiniti Q60 (3). This means the ATS Coupe produces up to 16.5 pounds less smog-producing pollutants than the Q60 every 15,000 miles.

Transmission

An eight-speed automatic is standard on the Cadillac ATS Coupe, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the Q60.

Brakes and Stopping

The ATS Coupe stops shorter than the Q60:

Car and Driver

Tires and Wheels

The ATS Coupe’s 255/35R18 rear tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the Q60’s standard 40 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the ATS Coupe can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. Run-flat tires aren’t available on some tire packages on the Q60.

Suspension and Handling

The ATS Coupe’s front to rear weight distribution is more even (51% to 49%) than the Q60’s (55% to 45%). This gives the ATS Coupe more stable handling and braking.

The ATS Coupe handles at .94 G’s, while the Q60 Red Sport 400 AWD pulls only .88 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the ATS Coupe FE3’s turning circle is .7 feet tighter than the Q60’s (36 feet vs. 36.7 feet).

Chassis

The Cadillac ATS Coupe may be more efficient, handle and accelerate better because it weighs about 350 pounds less than the Infiniti Q60.

Passenger Space

The ATS Coupe has .2 inches more front hip room, .6 inches more rear headroom and 1.1 inches more rear legroom than the Q60.

Cargo Capacity

The ATS Coupe has a much larger trunk than the Q60 (10.4 vs. 8.7 cubic feet).

The ATS 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.

Towing

The ATS Coupe V6 offers up to a 1000 lbs. towing capacity. The Q60 has no towing capacity.

Servicing Ease

The ATS 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

The ATS Coupe’s optional easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Q60 doesn’t offer an easy entry system.

The ATS Coupe V6 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.

Keyless Access standard on the ATS 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.

The ATS Coupe has a standard center folding armrest for the rear passengers. A center armrest helps make rear passengers more comfortable. The Q60 doesn’t offer a rear seat center armrest.

Both the ATS Coupe and the Q60 offer rear vents. For greater rear passenger comfort, the ATS 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.

The ATS Coupe offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Q60 doesn’t offer a house-current electrical outlet.

Economic Advantages

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Cadillac ATS Coupe will be $1415 to $2106 less than for the Infiniti Q60.

Recommendations

A group of representative automotive journalists from North America selected the ATS as the 2013 North American Car of the Year. The Q60 has never been chosen.

The Cadillac ATS outsold the Infiniti Q60 by 20% during 2018.
