Compare the2025 Aston Martin VanquishVS 2025 Maserati GranCabrio

To maximize occupant safety, the front seat shoulder belts of the Aston Martin Vanquish have pretensioners to eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Maserati GranCabrio doesn’t offer pretensioners.

The Aston Martin Vanquish has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The GranCabrio doesn’t offer knee airbags.

The Vanquish’s standard 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. A lane departure warning system costs extra on the GranCabrio.

The Vanquish has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the GranCabrio’s blind spot costs extra.

To help make backing out of a parking space safer, the Vanquish has standard Rear Cross Traffic Assist, helping the driver avoid collisions. Maserati charges extra for Rear Cross Path on the GranCabrio.

Both the Vanquish and the GranCabrio have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights and rearview cameras.

The Vanquish’s corrosion warranty is 6 years and unlimited miles longer than the GranCabrio’s (10/unlimited vs. 4/50,000).

The GranCabrio’s redline is at 8000 RPM, which causes more engine wear, and a greater chance of a catastrophic engine failure. The Vanquish has a 7000 RPM redline.

The Vanquish’s 5.2 turbo V12 produces 341 more horsepower (824 vs. 483) and 377 lbs.-ft. more torque (738 vs. 361) than the GranCabrio’s standard 3.0 turbo V6. The Vanquish’s 5.2 turbo V12 produces 282 more horsepower (824 vs. 542) and 259 lbs.-ft. more torque (738 vs. 479) than the GranCabrio’s optional 3.0 turbo V6.

The Vanquish has 3.1 gallons more fuel capacity than the GranCabrio (21.6 vs. 18.5 gallons), for longer range between fill-ups.

For better stopping power the Vanquish’s brake rotors are larger than those on the GranCabrio:

The Vanquish has standard heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The GranCabrio doesn’t offer ceramic brake rotors.

The Vanquish stops shorter than the GranCabrio:

For better traction, the Vanquish has larger tires than the GranCabrio (F:275/35R21 & R:325/30R21 vs. F:265/30R20 & R:295/30R21).

For better ride, handling and brake cooling the Vanquish has standard 21-inch wheels. Only 20-inch front wheels are available on the GranCabrio.

For better handling and stability, the track (width between the wheels) on the Vanquish is 1.3 inches wider in the front and .4 inches wider in the rear than on the GranCabrio.

The Vanquish is 3 inches shorter than the GranCabrio, making the Vanquish easier to handle, maneuver and park in tight spaces.

The Vanquish uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The GranCabrio doesn’t offer active noise cancellation.

The Vanquish Volante has a much larger trunk with its top down than the GranCabrio with its top down (6.4 vs. 4.6 cubic feet). The Vanquish Volante has a much larger trunk with its top up than the GranCabrio with its top up (7.7 vs. 6.1 cubic feet).

If the windows are left open on the Vanquish the driver can close them all from a distance using the remote. On a hot day the driver can also lower the windows the same way. The driver of the GranCabrio can only operate the windows from inside the vehicle, with the ignition on.

In case of a sudden change of weather, the Vanquish Convertible has a standard remote convertible top that can be raised from a distance to protect the interior of the vehicle from damage. On a hot day the Vanquish Convertible has a standard remote opening feature, to lower the top from outside. The GranCabrio doesn’t offer a remote top, so the driver will have to run to the car, get in, turn the ignition on and raise the top to prevent the interior from being damaged.
