The Q70’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Quattroporte doesn’t offer pre-crash pretensioners.

Over 200 people are killed each year when backed over by motor vehicles. The Q70 offers optional Backup Collision Intervention which use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Quattroporte doesn’t offer backup collision prevention brakes.

The Q70 offers optional INFINITI Connection, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in or send emergency personnel to the scene if any airbags deploy. The Quattroporte 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 Q70 and the Quattroporte have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Q70 the rating of “Top Pick” for 2017, a rating granted to only 149 vehicles tested by the IIHS. The Quattroporte has not been tested, yet.


The Q70 comes with a full 4-year/60,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Quattroporte’s 4-year/50,000-mile basic warranty expires 10,000 miles sooner.

Infiniti’s powertrain warranty covers the Q70 2 years and 20,000 miles longer than Maserati covers the Quattroporte. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Quattroporte ends after only 4 years or 50,000 miles.

The Q70’s corrosion warranty is 3 years and unlimited miles longer than the Quattroporte’s (7/unlimited vs. 4/50,000).

There are almost 2 times as many Infiniti dealers as there are Maserati dealers, which makes it much easier should you ever need service under the Q70’s warranty.

Fuel Economy and Range

On the EPA test cycle the Q70 5.6 LUXE RWD V8 gets better fuel mileage than the Quattroporte S RWD (16 city/24 hwy vs. 16 city/23 hwy).

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Infiniti Q70 higher (3 out of 10) than the Maserati Quattroporte (1). This means the Q70 produces up to 22.5 pounds less smog-producing pollutants than the Quattroporte every 15,000 miles.

Suspension and Handling

For better maneuverability, the Q70’s turning circle is 2 feet tighter than the Quattroporte’s (36.7 feet vs. 38.7 feet). The Q70 AWD’s turning circle is 1.3 feet tighter than the Quattroporte’s (37.4 feet vs. 38.7 feet).


The Infiniti Q70 may be more efficient, handle and accelerate better because it weighs up to about 200 pounds less than the Maserati Quattroporte.

The Q70 is 11.1 inches shorter than the Quattroporte, making the Q70 easier to handle, maneuver and park in tight spaces. The Q70L is 5.2 inches shorter than the Quattroporte.

The design of the Infiniti Q70 amounts to more than styling. The Q70 has an aerodynamic coefficient of drag of .27 Cd. That is significantly lower than the Quattroporte (.31) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Q70 get better fuel mileage.

The Q70 uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Quattroporte doesn’t offer active noise cancellation.

Passenger Space

The Q70 has .5 inches more front headroom and 1.4 inches more rear shoulder room than the Quattroporte.

Cargo Capacity

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the Q70 offers cargo security. The Quattroporte’s non-lockable folding seat and non-lockable remote release defeat cargo security.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Q70. The Quattroporte doesn’t offer locking storage for small valuables.


If the windows are left open on the Q70 the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. The driver of the Quattroporte can only operate the windows from inside the vehicle, with the ignition on.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Q70 has standard extendable sun visors. The Quattroporte doesn’t offer extendable visors.


Consumer Reports® recommends the Infiniti Q70, based on reliability, safety and performance.

J.D. Power and Associates rated the Q70 second among midsize premium cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Quattroporte isn’t in the top three.

The Infiniti Q70 outsold the Maserati Quattroporte by over three to one during 2017.
