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 LaCrosse 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 Arteon offers optional Maneuver Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The LaCrosse doesn’t offer backup collision prevention brakes.
The Arteon offers an optional Overhead View Camera to allow the driver to see objects all around the vehicle on a screen. The LaCrosse 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 LaCrosse have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee 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, daytime running lights, rearview cameras, available all wheel drive and lane departure warning systems.
The Arteon comes with a full 6-year/72000-mile basic warranty, which covers the entire car. The LaCrosse’s 4-year/50,000-mile basic warranty expires 2 years and 22000 miles sooner.
The Arteon’s corrosion warranty is 4 years longer than the LaCrosse’s (10 vs. 6 years).
The Volkswagen Arteon’s engine uses a cast iron block for durability, while the LaCrosse’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.
From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Volkswagen vehicles are more reliable than Buick vehicles. Consumer Reports ranks Volkswagen 3 places higher in reliability than Buick.
The Arteon’s 2.0 turbo 4 cyl. produces 74 more horsepower (268 vs. 194) and 71 lbs.-ft. more torque (258 vs. 187) than the LaCrosse’s standard 2.5 DOHC 4 cyl. hybrid.
On the EPA test cycle the Arteon FWD gets better fuel mileage than the LaCrosse FWD V6 (22 city/31 hwy vs. 20 city/30 hwy).
The Arteon has 1.6 gallons more fuel capacity than the LaCrosse FWD’s standard fuel tank (17.4 vs. 15.8 gallons), for longer range between fill-ups. The Arteon has 1.2 gallons more fuel capacity than the LaCrosse AWD’s standard fuel tank (17.4 vs. 16.2 gallons).
For better stopping power the Arteon’s brake rotors are larger than those on the LaCrosse:
For better traction, the Arteon has larger tires than the LaCrosse (245/45R18 vs. 235/50R18).
The Arteon’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 LaCrosse’s standard 50 series tires.
The Arteon is 6.1 inches shorter than the LaCrosse, making the Arteon easier to handle, maneuver and park in tight spaces.
Because it has more passenger and cargo room, the EPA rates the Arteon a Large car, while the LaCrosse is rated a Mid-size.
The Arteon has a much larger trunk than the LaCrosse (27.2 vs. 15 cubic feet). The Arteon has a much larger trunk than the LaCrosse eAssist (27.2 vs. 14.3 cubic feet).
To allow full utilization of available cargo room, the Arteon’s hatch uses gas strut supported hinges that don’t intrude into the cargo area. Its intrusive beam hinge reduces the LaCrosse’s useful trunk space.
A standard locking glovebox keeps your small valuables safer in the Arteon. The LaCrosse doesn’t offer locking storage for small valuables.
To make loading and unloading groceries and cargo easier when your hands are full, the Arteon SEL Premium’s power liftgate can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The LaCrosse doesn’t offer a power or hands-free opening trunk.
The Arteon’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The LaCrosse’s rear power window switches have to be held the entire time to close them fully.
KESSY Keyless Access standard on the Arteon 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 Buick LaCrosse’s Keyless Access doesn’t unlock the trunk.
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 LaCrosse’s manually variable intermittent wipers have to be constantly adjusted.
While driving with high beams on, sensitive light sensors available for the Arteon detect other vehicles which could be blinded and automatically switch to low beams. The LaCrosse doesn’t offer automatic dimming high beams.
The Arteon has standard heated front seats. Heated front seats are only available on the LaCrosse Sport Touring/Essence/Premium/Avenir. 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 LaCrosse.
