The TLX V6’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.

The TLX V6 offers an optional Surround View Camera System 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 TLX and the LaCrosse have standard driver and passenger frontal airbags, front side-impact airbags, driver 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 blind spot warning systems and rear cross-path warning.


The TLX’s standard 2.4 DOHC 4 cyl. produces 12 more horsepower (206 vs. 194) than the LaCrosse’s standard 2.5 DOHC 4 cyl. hybrid.

Fuel Economy and Range

The TLX has 1.4 gallons more fuel capacity than the LaCrosse FWD’s standard fuel tank (17.2 vs. 15.8 gallons), for longer range between fill-ups. The TLX has a gallon more fuel capacity than the LaCrosse AWD’s standard fuel tank (17.2 vs. 16.2 gallons).


The TLX offers a standard 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 LaCrosse doesn’t offer an SMG or a conventional manual transmission.

Tires and Wheels

The TLX has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The LaCrosse doesn’t offer vehicle monitored tire inflation.


The TLX is 6.8 inches shorter than the LaCrosse, making the TLX easier to handle, maneuver and park in tight spaces.

Passenger Space

The TLX has .6 inches more front legroom and .5 inches more front hip room than the LaCrosse.

Cargo Capacity

To allow full utilization of available cargo room, the TLX’s trunk lid uses concealed beam hinges that don’t intrude into the trunk. Its intrusive beam hinge reduces the LaCrosse’s useful trunk space.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the TLX. The LaCrosse doesn’t offer locking storage for small valuables.


The TLX’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 TLX 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.

Keyless Access System standard on the TLX 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 (optional Keyless Access System will also allow unlocking the passenger doors without taking your keys out). The Buick LaCrosse’s Keyless Access doesn’t unlock the trunk.

The TLX 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 TLX’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 TLX’s optional wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield.

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

While driving with high beams on, sensitive light sensors standard on the TLX detect other vehicles which could be blinded and automatically switch to low beams. The LaCrosse doesn’t offer automatic dimming high beams.

The TLX has standard heated front seats. Heated front seats are only available on the LaCrosse Essence/Premium. The TLX Advance also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the LaCrosse.

Economic Advantages

Insurance will cost less for the TLX owner. The Complete Car Cost Guide estimates that insurance for the TLX will cost $640 less than the LaCrosse over a five-year period.

The TLX will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the TLX will retain 43.93% to 47.86% of its original price after five years, while the LaCrosse only retains 42.39% to 43.68%.

According to The Car Book by Jack Gillis, the TLX is less expensive to operate than the LaCrosse because it costs $315 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the TLX than the LaCrosse, including $201 less for a water pump, $130 less for front brake pads, $256 less for fuel injection, $49 less for a fuel pump, $473 less for front struts and $848 less for a timing belt/chain.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Acura TLX will be $1110 to $4291 less than for the Buick LaCrosse.


The Acura TLX outsold the Buick LaCrosse by 73% during 2017.
