Safety Comparison

The ATS Coupe V6’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Accord Coupe doesn’t offer pre-crash pretensioners.

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 Honda Accord Coupe doesn’t offer height adjustable seat belts.

Over 200 people are killed each year when backed over by motor vehicles. The ATS Coupe V6 offers optional Rear Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Accord Coupe doesn’t offer backup collision prevention brakes.

The ATS Coupe offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Accord Coupe doesn’t offer all-wheel drive.

To help make backing safer, the ATS Coupe’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Accord Coupe doesn’t offer a cross-path warning system.

The ATS Coupe has standard OnStar®, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Accord Coupe doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

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

Warranty Comparison

The ATS Coupe comes with a full 4 year/50,000 mile basic warranty, which covers the entire car and includes 24 hour roadside assistance. The Accord Coupe’s 3 year/36,000 mile basic warranty expires 1 year and 14,000 miles sooner.

Cadillac’s powertrain warranty covers the ATS Coupe 1 year and 10,000 miles longer than Honda covers the Accord Coupe. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Accord Coupe ends after only 5 years or 60,000 miles.

The ATS Coupe’s corrosion warranty is 1 year longer than the Accord Coupe’s (6 vs. 5 years).

Cadillac pays for scheduled maintenance on the ATS Coupe for 3 years and 36,000 miles. Cadillac will pay for oil changes, lubrication and any other required maintenance. Honda doesn’t pay scheduled maintenance for the Accord Coupe.

Reliability Comparison

The camshafts in the ATS Coupe’s engine are driven by a hardened steel chain, with no maintenance needs. The Accord Coupe EX-L V6/Touring 3.5 SOHC V6’s camshafts are driven by a rubber belt that needs periodic replacement. If the Accord Coupe’s cam drive belt breaks the engine could be severely damaged when the pistons hit the opened valves.

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 Accord Coupe’s battery is in the hot engine compartment.

J.D. Power and Associates’ 2016 Initial Quality Study of new car owners surveyed provide the statistics that show that Cadillac vehicles are better in initial quality than Honda vehicles. J.D. Power ranks Cadillac 16th in initial quality. With 7 more problems per 100 vehicles, Honda is ranked 23rd.

Engine Comparison

The ATS Coupe’s standard 2.0 turbo 4 cyl. produces 87 more horsepower (272 vs. 185) and 114 lbs.-ft. more torque (295 vs. 181) than the Accord Coupe’s standard 2.4 DOHC 4 cyl. The ATS Coupe’s 2.0 turbo 4 cyl. produces 43 lbs.-ft. more torque (295 vs. 252) than the Accord Coupe EX-L V6/Touring’s standard 3.5 SOHC V6. The ATS Coupe’s optional 3.6 DOHC V6 produces 57 more horsepower (335 vs. 278) and 33 lbs.-ft. more torque (285 vs. 252) than the Accord Coupe EX-L V6/Touring’s standard 3.5 SOHC V6.

Fuel Economy and Range Comparison

Car and Driver

Tires and Wheels Comparison

For better traction, the ATS Coupe has larger tires than the Accord Coupe (F:225/40R18 & R:255/35R18 vs. 215/55R17).

The ATS Coupe’s 225/40R18 front and 255/35R18 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the Accord Coupe LX-S’ standard 55 series tires. The ATS Coupe’s tires are lower profile than the Accord Coupe Touring’s 40 series tires.

For better ride, handling and brake cooling the ATS Coupe has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Accord Coupe LX-S.

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. The Accord Coupe doesn’t offer run-flat tires.

Suspension and Handling Comparison

The ATS Coupe offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The Accord Coupe’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the ATS Coupe’s wheelbase is 2 inches longer than on the Accord Coupe (109.3 inches vs. 107.3 inches).

The ATS Coupe’s front to rear weight distribution is more even (51% to 49%) than the Accord Coupe’s (60.3% to 39.7%). This gives the ATS Coupe more stable handling and braking.

The ATS Coupe handles at .94 G’s, while the Accord Coupe EX-L V6 pulls only .86 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the ATS Coupe FE3’s turning circle is 1.6 feet tighter than the Accord Coupe LX-S’ (36 feet vs. 37.6 feet). The ATS Coupe AWD’s turning circle is .9 feet tighter than the Accord Coupe EX/EX-L/Touring’s (38.1 feet vs. 39 feet).

Chassis Comparison

The ATS Coupe is 5.9 inches shorter than the Accord Coupe, making the ATS Coupe easier to handle, maneuver and park in tight spaces.

Cargo Capacity Comparison

To allow full utilization of available cargo room, the ATS Coupe’s trunk lid uses concealed beam hinges that don’t intrude into the trunk. The Accord Coupe’s useful trunk space is reduced by its intrusive beam hinge.

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

Ergonomics Comparison

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 Accord Coupe 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 Accord Coupe doesn’t offer a heads-up display.

The ATS Coupe’s front power windows open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Accord Coupe’s standard passenger windows don’t open or close automatically. The Accord Coupe EX/EX-L/Touring’s rear windows don’t close automatically.

To help drivers see further while navigating curves, the ATS Coupe offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Accord Coupe doesn’t offer cornering lights.

The ATS Coupe’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Honda only offers heated mirrors on the Accord Coupe EX/EX-L/Touring.

When the ATS Coupe with available tilt-down mirrors is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Accord Coupe’s mirrors don’t automatically adjust for backing.

The ATS Coupe offers optional automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Accord Coupe offers an automatic rear view mirror, but its side mirrors don’t dim.

On extremely cold Winter days, the ATS Coupe’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Accord Coupe doesn’t offer a heated steering wheel.

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

For greater rear passenger comfort, the ATS Coupe has standard rear a/c vents to keep rear occupants more comfortable. The Accord Coupe doesn’t offer rear 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 Accord Coupe doesn’t offer a house-current electrical outlet.

Economic Advantages Comparison

According to The Car Book by Jack Gillis, the ATS Coupe is less expensive to operate than the Accord Coupe because typical repairs cost less on the ATS Coupe than the Accord Coupe, including $54 less for fuel injection, $70 less for a fuel pump, $1 less for a timing belt/chain and $8 less for a power steering pump.

Recommendations Comparison

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