Compare the2023 Audi A3VS 2023 Volkswagen Jetta

The A3’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Jetta doesn’t offer pre-crash pretensioners.

Both the A3 and Jetta have child safety locks to prevent children from opening the rear doors. The A3 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Jetta’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Audi A3 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps 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 Jetta doesn’t offer knee airbags.

The A3 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Jetta doesn’t offer all-wheel drive.

The A3’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 Jetta.

Both the A3 and the Jetta have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, rearview cameras, available 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 standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the A3 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 101 vehicles tested by the IIHS. The Jetta is not even a standard “Top Safety Pick.”

The A3’s corrosion warranty is 5 years and unlimited miles longer than the Jetta’s (12/unlimited vs. 7/100,000).

The Audi A3’s engine uses a cast iron block for durability, while the Jetta’s engine uses an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

A hardened steel chain, with no maintenance needs, drives the camshafts in the A3’s engine. A rubber cam drive belt that needs periodic replacement drives the Jetta’s camshafts. If the Jetta’s belt breaks, the engine could be severely damaged when the pistons hit the opened valves.

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that Audi vehicles are more reliable than Volkswagen vehicles. Consumer Reports ranks Audi 10 places higher in reliability than Volkswagen.

The A3’s 2.0 turbo 4-cylinder hybrid produces 43 more horsepower (201 vs. 158) and 37 lbs.-ft. more torque (221 vs. 184) than the Jetta’s 1.5 turbo 4-cylinder.

Regenerative brakes improve the A3’s fuel efficiency by converting inertia back into energy instead of wasting it. The Jetta doesn’t offer a regenerative braking system.

The A3 Quattro’s standard fuel tank has 1.3 gallons more fuel capacity than the Jetta (14.5 vs. 13.2 gallons).

The Audi A3 comes standard with an automatic transmission, for driver comfort, especially in the city. Automatic costs extra on the Jetta.

The A3 offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Jetta doesn’t offer an SMG.

For better stopping power the A3’s brake rotors are larger than those on the Jetta:

The A3 stops much shorter than the Jetta:

For better traction, the A3 has larger tires than the Jetta (225/45R17 vs. 205/60R16).

The A3’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 Jetta S’ standard 60 series tires. The A3’s optional tires have a lower 40 series profile than the Jetta Sport/SE/SEL’s 55 series tires.

For better ride, handling and brake cooling the A3 has standard 17-inch wheels. Smaller 16-inch wheels are standard on the Jetta S. The A3’s optional 18-inch wheels are larger than the 17-inch wheels on the Jetta Sport/SE/SEL.

For superior ride and handling, the Audi A3 has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Volkswagen Jetta has a rear torsion beam axle, with a semi-independent rear suspension.

The A3 has standard front and rear gas-charged shocks for better control over choppy roads. The Jetta’s suspension doesn’t offer gas-charged shocks.

The A3 has standard front and rear stabilizer bars, which help keep the A3 flat and controlled during cornering. The Jetta’s suspension doesn’t offer a rear stabilizer bar.

The A3 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 Jetta’s suspension doesn’t offer adjustable shock absorbers.

The A3 is 9.6 inches shorter than the Jetta, making the A3 easier to handle, maneuver and park in tight spaces.

To allow full utilization of available cargo room, the A3’s trunk lid uses concealed beam hinges that don’t intrude into the trunk. The Jetta’s useful trunk space is reduced by its intrusive beam hinge.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the A3. The Jetta doesn’t offer locking storage for small valuables.

To make loading and unloading groceries and cargo easier, especially for short adults, the A3 has a standard 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 Jetta doesn’t offer a power trunk.

The A3 uses gas struts to support the hood for easier service access. The Jetta uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

J.D. Power and Associates surveys of service recipients show that Audi service is better than Volkswagen. J.D. Power ranks Audi 8th in service department satisfaction (above the industry average). With a 32% lower rating, Volkswagen is ranked 28th.

If the windows are left open on the A3 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Jetta can’t use the remote to operate the windows.

The A3’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Jetta’s standard manually variable intermittent wipers have to be constantly adjusted.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The A3’s headlights were rated “Good” by the IIHS, while the Jetta’s headlights are rated “Marginal” to “Poor.”

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A3 Prestige has standard headlight washers to keep headlight output high. The Jetta doesn’t offer headlight washers.

When the A3 with available tilt-down mirrors 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 Jetta’s mirror doesn’t automatically adjust for backing.

The A3’s optional rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Jetta offers an automatic rear view mirror, but its side mirrors don’t dim.

The A3 has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning is only available on the Jetta SE/SEL.

Both the A3 and the Jetta offer rear vents. For greater rear passenger comfort, the A3 has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Jetta doesn’t offer rear air conditioning vents, only heat vents.

The A3’s optional Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Jetta doesn’t offer an automated parking system.
