The rear seatbelts optional on the Fusion inflate when a collision is detected, helping to spread crash forces over a much larger area of the body and limiting head and neck movement. This can help prevent spinal and internal injuries. The LaCrosse doesn’t offer inflatable seatbelts.
The Fusion (except S)’s optional driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The LaCrosse doesn’t offer a driver alert monitor.
Both the Fusion 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 crash mitigating brakes, lane departure warning systems, blind spot warning systems, front and rear parking sensors and rear cross-path warning.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Fusion its highest rating: “Top Pick Plus” for 2016, a rating granted to only 90 vehicles tested by the IIHS. The LaCrosse has not been tested, yet.
There are over 40 percent more Ford dealers than there are Buick dealers, which makes it easier should you ever need service under the Fusion’s warranty.
The Fusion’s optional 2.0 turbo 4 cyl. produces 7 lbs.-ft. more torque (275 vs. 268) than the LaCrosse’s 3.6 DOHC V6. The Fusion Sport’s standard 2.7 turbo V6 produces 20 more horsepower (325 vs. 305) and 82 lbs.-ft. more torque (350 vs. 268) than the LaCrosse’s 3.6 DOHC V6.
On the EPA test cycle the Fusion FWD 1.5 turbo 4 cyl. gets better fuel mileage than the LaCrosse FWD (23 city/34 hwy vs. 21 city/31 hwy).
The Fusion AWD’s standard fuel tank has 1.8 gallons more fuel capacity than the LaCrosse AWD’s standard fuel tank (18 vs. 16.2 gallons).
The Fusion’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The LaCrosse doesn’t offer drift compensation steering.
The Fusion SE handles at .87 G’s, while the LaCrosse Essence pulls only .83 G’s of cornering force in a Car and Driver skidpad test.
The Fusion is 5.7 inches shorter than the LaCrosse, making the Fusion easier to handle, maneuver and park in tight spaces.
The Fusion has .8 inches more front headroom, 2.3 inches more front legroom, .2 inches more front hip room, .1 inches more front shoulder room, .6 inches more rear headroom and .3 inches more rear shoulder room than the LaCrosse.
The Fusion has a larger trunk than the LaCrosse (16 vs. 15 cubic feet).
To allow full utilization of available cargo room, the Fusion’s trunk lid uses concealed beam hinges that don’t intrude into the trunk. The LaCrosse’s useful trunk space is reduced by its intrusive beam hinge.
A standard locking glovebox keeps your small valuables safer in the Fusion. The LaCrosse doesn’t offer locking storage for small valuables.
The Fusion’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.
If the windows are left down on the Fusion the driver can raise them all using the keyless remote; on a hot day the driver can lower the windows. The driver of the LaCrosse can only operate the windows from inside the vehicle, with the ignition on.
In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Fusion SE/Titanium/Sport/Platinum’s exterior keypad. The LaCrosse doesn’t offer an exterior keypad entry system, and its OnStar® can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.
The Fusion has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The LaCrosse doesn’t offer a locking fuel door.
The Fusion’s standard speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The LaCrosse’s manually variable intermittent wipers have to be constantly adjusted. The Fusion’s optional wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield.
While driving with high beams on, sensitive light sensors available for the Fusion (except S) detect other vehicles which could be blinded and automatically switch to low beams. The LaCrosse doesn’t offer automatic dimming high beams.
On extremely cold winter days, the Fusion’s optional (except S) heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The LaCrosse doesn’t offer a heated steering wheel.
