Safety Comparison

For enhanced safety, the front and rear seat shoulder belts of the Maserati Ghibli have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Acura TLX doesn’t offer pretensioners for the rear seat belts.

The Ghibli has standard whiplash protection, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the whiplash protection system moves the headrests forward to prevent neck and spine injuries. The TLX doesn’t offer a whiplash protection system.

Both the Ghibli and the TLX have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height-adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and available all wheel drive.

Reliability Comparison

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

Engine Comparison

The Ghibli’s standard 3.0 turbo V6 produces 139 more horsepower (345 vs. 206) and 187 lbs.-ft. more torque (369 vs. 182) than the TLX’s standard 2.4 DOHC 4 cyl. The Ghibli’s 3.0 turbo V6 produces 55 more horsepower (345 vs. 290) and 102 lbs.-ft. more torque (369 vs. 267) than the TLX’s optional 3.5 SOHC V6. The Ghibli S’ standard 3.0 turbo V6 produces 114 more horsepower (404 vs. 290) and 139 lbs.-ft. more torque (406 vs. 267) than the TLX’s optional 3.5 SOHC V6.

Tires and Wheels Comparison

For better traction, the Ghibli has larger standard tires than the TLX (235/50R18 vs. 225/55R17). The Ghibli’s optional tires are larger than the largest tires available on the TLX (F:245/40R20 & R:285/35R20 vs. 225/55R17).

The Ghibli’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the TLX’s standard 55 series tires. The Ghibli’s optional 245/35R21 front and 285/30R21 rear tires have a lower 35 series front and 30 series rear profile than the TLX V-6’s 50 series tires.

For better ride, handling and brake cooling the Ghibli has standard 18-inch wheels. Smaller 17-inch wheels are standard on the TLX. The Ghibli’s optional 21-inch wheels are larger than the 18-inch wheels on the TLX V-6.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the Ghibli can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The TLX doesn’t offer run-flat tires.

Suspension and Handling Comparison

The Ghibli offers an optional 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 TLX’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the Ghibli’s wheelbase is 8.7 inches longer than on the TLX (118 inches vs. 109.3 inches).

For better handling and stability, the track (width between the wheels) on the Ghibli is 1.6 inches wider in the front and 2 inches wider in the rear than on the TLX.

The Ghibli’s front to rear weight distribution is more even (50% to 50%) than the TLX’s (60% to 40%). This gives the Ghibli more stable handling and braking.

The Ghibli S Q4 handles at .91 G’s, while the TLX V-6 SH-AWD pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

The Ghibli S Q4 executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the TLX (25.5 seconds @ .8 average G’s vs. 27 seconds @ .74 average G’s).

For better maneuverability, the Ghibli’s turning circle is .4 feet tighter than the TLX V-6’s (38.4 feet vs. 38.8 feet). The Ghibli’s turning circle is 1.1 feet tighter than the TLX SH-AWD’s (38.4 feet vs. 39.5 feet).

Passenger Space Comparison

Because it has more passenger and cargo room, the Ghibli is rated a Large car by the EPA, while the TLX is rated a Compact.

The Ghibli has 14.7 cubic feet more passenger volume than the TLX (108 vs. 93.3).

The Ghibli has 1.6 inches more front headroom, .3 inches more front shoulder room, 2.1 inches more rear headroom and 1.1 inches more rear shoulder room than the TLX.

Cargo Capacity Comparison

The Ghibli has a much larger trunk than the TLX (17.6 vs. 13.2 cubic feet).

Ergonomics Comparison

The Ghibli’s instruments include an oil pressure gauge and a temperature gauge – which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The TLX does not have an oil pressure gauge.

The power windows standard on both the Ghibli and the TLX have locks to prevent small children from operating them. When the lock on the Ghibli is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The TLX prevents the driver from operating the other windows just as it does the other passengers.

Heated windshield washer nozzles are standard on the Ghibli to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The TLX doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Ghibli offers available headlight washers to keep headlight output high. The TLX doesn’t offer headlight washers.

While driving with high beams on, sensitive light sensors available for the Ghibli detect other vehicles which could be blinded and automatically switch to low beams. The TLX doesn’t offer automatic dimming high beams.

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

A power rear sunshade is optional in the Ghibli to help block heat and glare for the rear passengers. The TLX doesn’t offer a rear sunshade.

Both the Ghibli and the TLX offer available heated front seats. The Ghibli also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the TLX.

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