Safety

For enhanced safety, the front seat shoulder belts of the Volkswagen Jetta GLI 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 Jetta GLI has a standard Automatic Post-Collision Braking System, 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 Jetta GLI has a standard backup collision prevention system 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 Jetta GLI Autobahn has standard Car-Net, 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 Giulia 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 Jetta GLI 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 and rearview cameras.

Warranty

The Jetta GLI comes with a full 6-year/72000-mile basic warranty, which covers the entire car. The Giulia’s 4-year/50,000-mile basic warranty expires 2 years and 22000 miles sooner.

The Jetta GLI’s corrosion warranty is 6 years longer than the Giulia’s (10 vs. 4 years).

There are almost 4 times as many Volkswagen dealers as there are Alfa Romeo dealers, which makes it much easier should you ever need service under the Jetta GLI’s warranty.

Reliability

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

Engine

As tested in Car and Driver the Volkswagen Jetta GLI is faster than the Alfa Romeo Giulia 2.0T (automatics tested):

Environmental Friendliness

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

Transmission

The Jetta GLI offers a manual transmission for better acceleration, control and fuel economy. The Giulia doesn’t offer a manual transmission.

The Jetta GLI offers an optional 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 Giulia doesn’t offer an SMG.

Brakes and Stopping

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

The Jetta GLI’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 Jetta GLI stops much shorter than the Giulia:

Car and Driver

Tires and Wheels

The Jetta GLI’s tires provide better handling because they have a lower 40 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 Jetta GLI has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Giulia.

The Jetta GLI has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Giulia; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

Suspension and Handling

The Jetta GLI 35th Anniversary Edition handles at .95 G’s, while the Giulia Ti Q4 pulls only .79 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the Jetta GLI’s turning circle is 1.1 feet tighter than the Giulia’s (36.4 feet vs. 37.5 feet).

Chassis

The Volkswagen Jetta GLI may be more efficient, handle and accelerate better because it weighs about 300 to 350 pounds less than the Alfa Romeo Giulia.

Passenger Space

The Jetta GLI has 2.3 inches more rear legroom and .4 inches more rear shoulder room than the Giulia.

Cargo Capacity

The Jetta GLI has a much larger trunk than the Giulia (14.1 vs. 12 cubic feet).

Ergonomics

If the windows are left open on the Jetta GLI the driver can close them all at the outside door handle. On a hot day the driver can lower the windows with the driver’s door power window switch. The driver of the Giulia can only operate the windows from inside the vehicle, with the ignition on.

Keyless Access standard on the Jetta GLI allows you to unlock the driver’s door, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Alfa Romeo Giulia’s Keyless-Go doesn’t unlock the trunk.

Standard air-conditioned seats in the Jetta GLI Autobahn 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.
