Compare the2022 BMW 3 Series SedanVS 2021 Alfa Romeo Giulia

The 3 Series Sedan’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Giulia doesn’t offer pre-crash pretensioners.

The 3 Series Sedan 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 3 Series Sedan has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Giulia doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The 3 Series Sedan offers optional Active Park Distance Control that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Giulia doesn’t offer backup collision prevention brakes.

The 3 Series Sedan’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 Giulia.

Both the 3 Series Sedan and the Giulia have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available all wheel drive, blind spot warning systems, rear parking sensors and rear cross-path warning.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the 3 Series Sedan the rating of “Top Pick” for 2021, a rating granted to only 121 vehicles tested by the IIHS. The Giulia has not been fully tested, yet.

The 3 Series Sedan’s corrosion warranty is 7 years longer than the Giulia’s (12 vs. 5 years).

BMW pays for scheduled maintenance on the 3 Series Sedan for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Alfa Romeo only pays for the first scheduled maintenance visit on the Giulia.

There are over 2 times as many BMW dealers as there are Alfa Romeo dealers, which makes it much easier should you ever need service under the 3 Series Sedan’s warranty.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the 3 Series Sedan’s reliability 59 points higher than the Giulia.

J.D. Power and Associates’ 2021 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than Alfa Romeo vehicles. J.D. Power ranks BMW 10th in reliability, above the industry average. With 88 more problems per 100 vehicles, Alfa Romeo is ranked 32nd.

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that BMW vehicles are more reliable than Alfa Romeo vehicles. Consumer Reports ranks BMW 17 places higher in reliability than Alfa Romeo.

The M340i’s standard 3.0 turbo 6-cylinder hybrid produces 102 more horsepower (382 vs. 280) and 62 lbs.-ft. more torque (368 vs. 306) than the Giulia’s 2.0 turbo 4-cylinder.

As tested in Car and Driver the BMW 3 Series Sedan is faster than the Alfa Romeo Giulia:

On the EPA test cycle the 3 Series Sedan gets better mileage than the Giulia:

Regenerative brakes improve the 3 Series Sedan’s fuel efficiency by converting inertia back into energy instead of wasting it. The Giulia doesn’t offer a regenerative braking system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the BMW 3 Series Sedan higher (5 to 7 out of 10) than the Alfa Romeo Giulia (3). This means the 3 Series Sedan produces up to 24.5 pounds less smog-producing pollutants than the Giulia every 15,000 miles.

The 3 Series Sedan’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Giulia doesn’t offer launch control.

For better stopping power the M340i’s brake rotors are larger than those on the Giulia:

The 3 Series Sedan’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.

The 3 Series Sedan stops much shorter than the Giulia:

The 330i’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. The 3 Series Sedan’s optional 225/35R20 front and 255/30R20 rear tires have a lower 35 series front and 30 series rear profile than the Giulia Sport/Ti’s optional 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the 330i has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Giulia. The 3 Series Sedan’s optional 20-inch wheels are larger than the 19-inch wheels optional on the Giulia Ti.

For a smoother ride and more stable handling, the 3 Series Sedan’s wheelbase is 1.2 inches longer than on the Giulia (112.2 inches vs. 111 inches).

The 330i handles at .99 G’s, while the Giulia Ti Q4 pulls only .79 G’s of cornering force in a Car and Driver skidpad test.

The M340i executes Motor Trend’s “Figure Eight” maneuver 2.1 seconds quicker than the Giulia Ti (25 seconds @ .77 average G’s vs. 27.1 seconds @ .66 average G’s).

The design of the BMW 3 Series Sedan amounts to more than styling. The 3 Series Sedan has an aerodynamic coefficient of drag of .26 Cd. That is lower than the Giulia (.28) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the 3 Series Sedan get better fuel mileage.

The front grille of the 3 Series Sedan uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Giulia doesn’t offer active grille shutters.

As tested by Car and Driver, the interior of the 330i is quieter than the Giulia Ti:

The 3 Series Sedan has .1 inches more front headroom, .1 inches more rear legroom and 1 inch more rear shoulder room than the Giulia.

The 3 Series Sedan has a larger trunk than the Giulia (13 vs. 12 cubic feet).

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the 3 Series offers cargo security. The Giulia’s non-lockable remote release defeats cargo security.

To make loading and unloading groceries and cargo easier, especially for short adults, the 3 Series Sedan offers an optional power trunk, which opens and closes automatically by pressing a button, or optionally by just kicking your foot under the back bumper, completely leaving your hands free. The Giulia doesn’t offer a power trunk.

J.D. Power and Associates surveys of service recipients show that BMW service is better than Alfa Romeo. J.D. Power ranks BMW 8th in service department satisfaction (above the industry average). With a 69% lower rating, Alfa Romeo is ranked 32nd.

The 3 Series Sedan offers an optional heads-up display that projects speed, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Giulia doesn’t offer a heads-up display.

If the windows are left open on the 3 Series Sedan the driver can close them all at the outside door handle. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Giulia can only operate the windows from inside the vehicle, with the ignition on.

When the 3 Series Sedan is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Giulia’s mirror doesn’t automatically adjust for backing.
