The Q50 Sport/Red Sport 400’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The LaCrosse doesn’t offer pre-crash pretensioners.

Over 200 people are killed each year when backed over by motor vehicles. The Q50 (except Pure) offers optional Back-up Collision Intervention 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 Q50 (except Pure) offers an optional Around View® Monitor 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 Q50 and the LaCrosse have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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, lane departure warning systems, blind spot warning systems and rear cross-path warning.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Infiniti Q50 is safer than the Buick LaCrosse:

The Q50 3.0t’s standard 3.0 turbo V6 produces 106 more horsepower (300 vs. 194) and 108 lbs.-ft. more torque (295 vs. 187) than the LaCrosse’s standard 2.5 DOHC 4 cyl. hybrid.

The Q50 Red Sport 400’s 265/35R19 rear tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the LaCrosse Essence/Premium/Avenir’s optional 40 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the Q50 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The LaCrosse doesn’t offer run-flat tires.

The Q50 Sport’s optional 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 Q50’s front to rear weight distribution is more even (55.8% to 44.2%) than the LaCrosse’s (58.6% to 41.4%). This gives the Q50 more stable handling and braking.

The Q50 Red Sport 400 handles at .88 G’s, while the LaCrosse Essence pulls only .83 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the Q50’s turning circle is 1.3 feet tighter than the LaCrosse’s (36.7 feet vs. 38 feet). The Q50 AWD’s turning circle is .6 feet tighter than the LaCrosse’s (37.4 feet vs. 38 feet).

The Q50 is 7.9 inches shorter than the LaCrosse, making the Q50 easier to handle, maneuver and park in tight spaces.

To allow full utilization of available cargo room, the Q50’s trunk lid uses gas strut supported 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 (which can’t be accessed with the valet key) keeps your small valuables safer in the Q50. The LaCrosse doesn’t offer locking storage for small valuables.

The engine in the Q50 is mounted longitudinally (North-South), instead of sideways, as in the LaCrosse. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

J.D. Power and Associates surveys of service recipients show that Infiniti service is better than Buick. J.D. Power ranks Infiniti fourth in service department satisfaction. With a 21% lower rating, Buick is ranked 8th.

The Q50’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 open on the Q50 the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. The driver of the LaCrosse can only operate the windows from inside the vehicle, with the ignition on.

The Infiniti Intelligent Key standard on the Q50 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 Q50 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 Q50’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.

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 Q50’s available headlights were rated “Acceptable” by the IIHS, while the LaCrosse’s headlights are rated “Poor.”

While driving with high beams on, sensitive light sensors available for the Q50 Sport/Red Sport 400 detect other vehicles which could be blinded and automatically switch to low beams. The LaCrosse doesn’t offer automatic dimming high beams.

Insurance will cost less for the Q50 owner. The Car Book by Jack Gillis rates the Q50 with a number “1” insurance rate while the LaCrosse is rated higher at a number “5” rate.

The Q50 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Q50 will retain 36.99% to 46.1% of its original price after five years, while the LaCrosse only retains 30.31% to 36.47%.

According to The Car Book by Jack Gillis, the Q50 is less expensive to operate than the LaCrosse because it costs $373 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the Q50 than the LaCrosse, including $178 less for a water pump, $111 less for front brake pads, $227 less for front struts and $424 less for a timing belt/chain.
