Fuel Economy and Range

On the EPA test cycle the Camaro Auto turbo 4-cylinder gets better fuel mileage than the ATS Coupe RWD turbo 4-cylinder (22 city/31 hwy vs. 22 city/30 hwy).

The Camaro has 3 gallons more fuel capacity than the ATS Coupe (19 vs. 16 gallons), for longer range between fill-ups.

The Camaro 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. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The ATS Coupe doesn’t offer a cap-less fueling system.


The Camaro offers a manual transmission for better acceleration, control and fuel economy. The ATS Coupe doesn’t offer a manual transmission.

A 10-speed automatic is available on the Chevrolet Camaro, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the ATS Coupe.

The Camaro (except 4-cylinder/V6)’s optional launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The ATS Coupe doesn’t offer launch control.

Brakes and Stopping

For better stopping power the Camaro ZL1’s brake rotors are larger than those on the ATS Coupe:

Tires and Wheels

For better traction, the Camaro has larger standard tires than the ATS Coupe (245/50R18 vs. 225/40R18). The Camaro ZL1 1LE Coupe’s tires are larger than the largest tires available on the ATS Coupe (F:305/30R19 & R:325/30R19 vs. F:225/40R18 & R:255/35R18).

The Camaro SS 1LE/ZL1’s tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the ATS Coupe’s 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the Camaro offers optional 20-inch wheels. The ATS Coupe’s largest wheels are only 18-inches.

The Camaro has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The ATS Coupe doesn’t offer vehicle monitored tire inflation.

Suspension and Handling

For a smoother ride and more stable handling, the Camaro’s wheelbase is 1.4 inches longer than on the ATS Coupe (110.7 inches vs. 109.3 inches).

For better handling and stability, the average track (width between the wheels) on the Camaro is 3 inches wider in the front and 1.1 inches wider in the rear than the track on the ATS Coupe.

The Camaro ZL1 1LE Coupe handles at 1.18 G’s, while the ATS Coupe pulls only .94 G’s of cornering force in a Car and Driver skidpad test.

The Camaro SS Coupe executes Motor Trend’s “Figure Eight” maneuver 2.7 seconds quicker than the ATS Coupe (22.9 seconds @ .91 average G’s vs. 25.6 seconds @ .71 average G’s).

Passenger Space

Because it has more passenger and cargo room, the EPA rates the Camaro Coupe a Compact car, while the ATS Coupe is rated a Subcompact.

The Camaro Coupe has 9.1 cubic feet more passenger volume than the ATS Coupe (93 vs. 83.9).

The Camaro Coupe has .9 inches more front headroom, 1.6 inches more front legroom, .4 inches more front hip room and .9 inches more front shoulder room than the ATS Coupe.


The Camaro’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The ATS Coupe does not have an oil pressure gauge.

The Camaro’s power parking brake sets with one touch and releases with one touch or automatically. The ATS Coupe has a lever-type parking brake that has to be strenuously raised to engage properly. It has to be lifted up more and a button depressed to release it.

Optional air-conditioned seats in the Camaro (except LS/LT1) keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The ATS Coupe doesn’t offer air-conditioned seats.

Model Availability

The Chevrolet Camaro comes in coupe and convertible bodystyles; the Cadillac ATS isn’t available as a convertible.

Economic Advantages

Insurance will cost less for the Camaro owner. The Car Book by Jack Gillis rates the Camaro with a number “1” insurance rate while the ATS Coupe is rated higher at a number “8” rate.

The Camaro will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Camaro will retain 45.92% to 53.69% of its original price after five years, while the ATS Coupe only retains 38.92% to 41.91%.

According to The Car Book by Jack Gillis, the Camaro is less expensive to operate than the ATS Coupe because typical repairs cost much less on the Camaro than the ATS Coupe, including $300 less for a water pump, $331 less for a muffler, $374 less for a starter, $274 less for fuel injection, $59 less for front struts and $370 less for a power steering pump.


J.D. Power and Associates rated the Camaro second among midsize sporty cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The ATS Coupe isn’t in the top three.

The Camaro was chosen as one of Car and Driver’s “Top Ten” for 3 of the last 4 years. The ATS Coupe has never been a Car and Driver “Top Ten” pick.

Motor Trend selected the Camaro as their 2016 Car of the Year. The ATS Coupe has never been chosen.

The Camaro was chosen as one of Automobile Magazine’s “All Stars” in 2013. The ATS Coupe has never been an “All Star.”

The Chevrolet Camaro outsold the Cadillac ATS by almost five to one during 2018.
