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 370Z doesn’t offer pre-crash pretensioners.
The ATS Coupe V6 offers optional Front Automatic Braking, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The 370Z doesn't offer collision warning or crash mitigation brakes.
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 370Z 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 370Z doesn’t offer all-wheel drive.
The ATS Coupe’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The 370Z doesn’t offer a lane departure warning system.
The ATS Coupe’s optional blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The 370Z doesn’t offer a system to reveal objects in the driver’s blind spots.
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 370Z doesn’t offer a cross-path warning system.
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 Nissan 370Z has a metal gas tank.
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 370Z 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 370Z 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 and available rear parking sensors.
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 370Z’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 Nissan covers the 370Z. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the 370Z ends after only 5 years or 60,000 miles.
The ATS Coupe’s corrosion warranty is 1 year longer than the 370Z’s (6 vs. 5 years).

The ATS Coupe’s standard 2.0 turbo 4 cyl. produces 25 lbs.-ft. more torque (295 vs. 270) than the 370Z’s standard 3.7 DOHC V6. The ATS Coupe’s 2.0 turbo 4 cyl. produces 19 lbs.-ft. more torque (295 vs. 276) than the 370Z NISMO Coupe’s standard 3.7 DOHC V6. The ATS Coupe’s optional 3.6 DOHC V6 produces 9 lbs.-ft. more torque (285 vs. 276) than the 370Z NISMO Coupe’s standard 3.7 DOHC V6.
On the EPA test cycle the ATS Coupe RWD V6 gets better fuel mileage than the 370Z Coupe Auto with its standard V6 (20 city/30 hwy vs. 19 city/26 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 370Z doesn’t offer a system that can shut down part of the engine.
In heavy traffic or at stoplights the ATS Coupe Auto’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. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The 370Z doesn’t offer an automatic engine start/stop system.
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 370Z requires premium, which can cost 20 to 55 cents more per gallon.
The ATS Coupe stops shorter than the 370Z:
70 to 0 MPH
Car and Driver
For better traction and acceleration, the ATS Coupe has larger rear tires than the 370Z (255/35R18 vs. 245/45R18).
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 370Z’s standard 50 series front and 45 series rear 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. The 370Z doesn’t offer run-flat tires.
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 370Z’s suspension doesn’t offer adjustable shock absorbers.
For a smoother ride and more stable handling, the ATS Coupe’s wheelbase is 8.9 inches longer than on the 370Z (109.3 inches vs. 100.4 inches).
The ATS Coupe’s front to rear weight distribution is more even (51% to 49%) than the 370Z’s (54.2% to 45.8%). This gives the ATS Coupe more stable handling and braking.
The ATS Coupe handles at .94 G’s, while the 370Z Coupe pulls only .91 G’s of cornering force in a Car and Driver skidpad test.
The ATS Coupe has standard seating for 4 passengers; the 370Z can only carry 2.
The ATS Coupe has 32.3 cubic feet more passenger volume than the 370Z (83.9 vs. 51.6).
The ATS Coupe has a much larger trunk than the 370Z Coupe (10.4 vs. 6.9 cubic feet).
The ATS Coupe (except Manual) has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The 370Z doesn’t offer a remote starting system.
To help each driver find a more comfortable driving position, the ATS Coupe V6 offers a telescoping steering wheel. Much better than just a tilt steering wheel or adjustable seat, this allows a short driver to sit further from the steering wheel while maintaining contact with the pedals. The 370Z doesn’t offer a telescoping steering wheel.
When two different drivers share the ATS Coupe, the optional memory system makes it convenient for both. Each keyless remote activates different, customized memories for the driver’s seat position, steering wheel position and outside mirror angle. The 370Z doesn’t offer a memory system.
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 370Z 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 370Z doesn’t offer a heads-up display.
The ATS Coupe’s optional wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The 370Z’s manually variable intermittent wipers have to be constantly adjusted.
While driving with high beams on, sensitive light sensors available for the ATS Coupe detect other vehicles which could be blinded and automatically switch to low beams. The 370Z doesn’t offer automatic dimming high beams.
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 370Z doesn’t offer cornering lights.
The ATS Coupe’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Nissan only offers heated mirrors on the 370Z Touring/Sport/NISMO.
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 370Z’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 370Z 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 370Z doesn’t offer a heated steering wheel.
The ATS Coupe’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The 370Z doesn’t offer dual zone air conditioning.
To keep a safe, consistent following distance, the ATS Coupe V6 offers an optional Adaptive Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The 370Z doesn’t offer an adaptive cruise control.
Standard CUE for the ATS Coupe allows the driver and passengers access to select programs on their smartphones, including reading text messages aloud, playing internet radio stations and other connected activities without taking their eyes off the road or their hands from the wheel. The 370Z doesn’t offer factory integrated smartphone program access.
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 370Z doesn’t offer a house-current electrical outlet.
According to The Car Book by Jack Gillis, the ATS Coupe is less expensive to operate than the 370Z because typical repairs cost much less on the ATS Coupe than the 370Z, including $257 less for a water pump, $119 less for a fuel pump, $116 less for front struts, $270 less for a timing belt/chain and $900 less for a power steering pump.
A group of representative automotive journalists from North America selected the ATS as the 2013 North American Car of the Year. The 370Z has never been chosen.
The Cadillac ATS outsold the Nissan 370Z by almost four to one during the 2016 model year.
