For enhanced safety, the Cadillac ATS-V’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 Maserati GranTurismo doesn’t offer comfort guides on its rear seat belts.
The ATS-V offers an optional collision warning system, which detects an impending crash through forward mounted sensors and flashes a bright light and sounds a loud, distinctive tone to warn the driver to brake or maneuver immediately to avoid a collision. The system also pre-charges the brakes to begin deceleration more quickly. The GranTurismo doesn't offer a collision warning system.
The ATS-V’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 GranTurismo doesn’t offer a lane departure warning system.
The ATS-V’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 GranTurismo doesn’t offer a system to reveal objects in the driver’s blind spots.
To help make backing safer, the ATS-V’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 GranTurismo doesn’t offer a cross-path warning system.
The ATS-V 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 GranTurismo 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-V and the GranTurismo 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 front and rear parking sensors.
Cadillac’s powertrain warranty covers the ATS-V 2 years and 20,000 miles longer than Maserati covers the GranTurismo.

The ATS-V’s corrosion warranty is 2 years and unlimited miles longer than the GranTurismo’s (6/unlimited vs. 4/50,000).
Cadillac pays for scheduled maintenance on the ATS-V for 3 years and 36,000 miles. Cadillac will pay for oil changes, lubrication and any other required maintenance. Maserati doesn’t pay scheduled maintenance for the GranTurismo.

For better traction, the ATS-V has larger front tires than the GranTurismo (255/35R18 vs. 245/35R20).
The Cadillac ATS-V may be more efficient, handle and accelerate better because it weighs about 350 pounds less than the Maserati GranTurismo.
The ATS-V Coupe is 8.6 inches shorter than the GranTurismo, making the ATS-V easier to handle, maneuver and park in tight spaces.

The ATS-V’s optional rear seats fold to accommodate long and bulky cargo. The GranTurismo doesn’t offer folding rear seats.
The ATS-V Automatic 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 GranTurismo doesn’t offer a remote starting system.
The ATS-V offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The GranTurismo doesn’t offer a heads-up display.
The ATS-V’s standard front power windows open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The GranTurismo’s front passenger window doesn’t close automatically.
Keyless Access standard on the ATS-V allows you to unlock the doors, 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 Maserati GranTurismo doesn’t offer an advanced key system.
While driving with high beams on, sensitive light sensors available for the ATS-V detect other vehicles which could be blinded and automatically switch to low beams. The GranTurismo doesn’t offer automatic dimming high beams.
