The Arteon 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 CT4 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.
The Arteon offers an optional Overhead View Camera to allow the driver to see objects all around the vehicle on a screen. The CT4 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.
Both the Arteon and the CT4 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, daytime running lights, rearview cameras, available all wheel drive and lane departure warning systems.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the Arteon the rating of “Top Pick” for 2017, a rating granted to only 185 vehicles tested by the IIHS. The CT4 has not been tested, yet.
The Arteon’s corrosion warranty is 1 year longer than the CT4’s (7 vs. 6 years).
Volkswagen pays for scheduled maintenance on the Arteon for 2 years and 20,000 miles. Volkswagen will pay for oil changes, lubrication and any other required maintenance. Cadillac only pays for the first scheduled maintenance visit on the CT4.
The Volkswagen Arteon’s engine uses a cast iron block for durability, while the CT4’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.
J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Volkswagen vehicles are more reliable than Cadillac vehicles. J.D. Power ranks Volkswagen 12th in reliability, above the industry average. With 35 more problems per 100 vehicles, Cadillac is ranked 23rd.
From surveys of all its subscribers, Consumer Reports’ December 2019 Auto Issue reports that Volkswagen vehicles are more reliable than Cadillac vehicles. Consumer Reports ranks Volkswagen 3 places higher in reliability than Cadillac.
The Arteon’s 2.0 turbo 4-cylinder produces 31 more horsepower (268 vs. 237) than the CT4’s standard 2.0 turbo 4-cylinder.
For better stopping power the Arteon’s front brake rotors are larger than those on the CT4:
For better traction, the Arteon has larger tires than the CT4 (245/45R18 vs. 225/45R17). The Arteon’s tires are larger than the largest tires available on the CT4 (245/45R18 vs. 235/40R18).
The Arteon’s optional tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the CT4 Premium Luxury’s 40 series tires.
For better ride, handling and brake cooling the Arteon has standard 18-inch wheels. Smaller 17-inch wheels are standard on the CT4. The Arteon’s optional 20-inch wheels are larger than the 18-inch wheels on the CT4 Premium Luxury.
The Arteon 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 CT4; 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. Some tire options on the CT4 don’t have a run-flat feature, either.
The Arteon has a standard 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 CT4’s suspension doesn’t offer adjustable shock absorbers.
For a smoother ride and more stable handling, the Arteon’s wheelbase is 2.6 inches longer than on the CT4 (111.9 inches vs. 109.3 inches).
For better handling and stability, the track (width between the wheels) on the Arteon is 2.2 inches wider in the front and .4 inches wider in the rear than on the CT4.
The Arteon has 1.3 inches more front shoulder room, .5 inches more rear headroom, 6.8 inches more rear legroom and .8 inches more rear shoulder room than the CT4.
To make loading groceries and cargo easier when your hands are full, the Arteon’s liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The CT4 doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.
The Arteon’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 CT4’s standard manually variable intermittent wipers have to be constantly adjusted.
The CT4 Premium Luxury/Sport’s optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The Arteon R-Line/SEL/SEL Premium’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.
The Arteon has standard heated front seats. Heated front seats cost extra on the CT4. The Arteon SEL Premium also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the CT4.
The Arteon’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 CT4 doesn’t offer an automated parking system.
Consumer Reports® recommends the Volkswagen Arteon, based on reliability, safety and performance.
