For enhanced safety, the front seat shoulder belts of the Nissan Maxima are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Alfa Romeo Giulia doesn’t offer height-adjustable seat belts.
The Maxima has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Giulia doesn’t offer a whiplash protection system.
The Maxima Platinum has a standard Around View® Monitor to allow the driver to see objects all around the vehicle on a screen. The Giulia only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
The Maxima Platinum’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Giulia doesn’t offer a driver alert monitor.
Both the Maxima and the Giulia 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, rearview cameras, available crash mitigating brakes, 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, with its optional front crash prevention system, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the Maxima its highest rating: “Top Pick Plus” for 2017, a rating granted to only 54 vehicles tested by the IIHS. The Giulia has not been tested, yet.
Nissan’s powertrain warranty covers the Maxima 1 year and 10,000 miles longer than Alfa Romeo covers the Giulia. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the Giulia ends after only 4 years or 50,000 miles.
The Maxima’s corrosion warranty is 1 year longer than the Giulia’s (5 vs. 4 years).
There are almost 7 times as many Nissan dealers as there are Alfa Romeo dealers, which makes it much easier should you ever need service under the Maxima’s warranty.
The Maxima’s 3.5 DOHC V6 produces 20 more horsepower (300 vs. 280) than the Giulia’s 2.0 turbo 4 cyl.
The Maxima has 2.7 gallons more fuel capacity than the Giulia (18 vs. 15.3 gallons), for longer range between fill-ups.
The Maxima’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Giulia are solid, not vented.
For better traction, the Maxima has larger tires than the Giulia (245/45R18 vs. 225/50R17).
The Maxima’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Giulia’s standard 50 series tires.
For better ride, handling and brake cooling the Maxima has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Giulia.
The Maxima has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Giulia doesn’t offer vehicle monitored tire inflation.
For better handling and stability, the track (width between the wheels) on the Maxima is 1.1 inches wider in the front than on the Giulia.
The Maxima 3.5 SR handles at .86 G’s, while the Giulia pulls only .84 G’s of cornering force in a Motor Trend skidpad test.
The Maxima SL/SR/Platinum uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Giulia doesn’t offer active noise cancellation.
The Maxima has 3.2 cubic feet more passenger volume than the Giulia (98.6 vs. 95.4).
The Maxima has .8 inches more front headroom, 2.6 inches more front legroom, .6 inches more front shoulder room and 2.1 inches more rear shoulder room than the Giulia.
The Maxima has a much larger trunk than the Giulia (14.3 vs. 12 cubic feet).
The Maxima’s standard rear seats fold to accommodate long and bulky cargo. The Giulia doesn’t offer folding rear seats.
A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Maxima. The Giulia doesn’t offer locking storage for small valuables.
The Maxima’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 Giulia has neither an oil pressure gauge nor a temperature gauge.
Standard air-conditioned seats in the Maxima SR/Platinum keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The Giulia doesn’t offer air-conditioned seats.
The Maxima has a standard center folding armrest for the rear passengers. A center armrest helps make rear passengers more comfortable. The Giulia doesn’t offer a rear seat center armrest.
