The third-generation Buick LaCrosse was introduced nearly three years ago at the 2015 Los Angeles Auto Show and it appears the company is already working on a minor facelift.

Spotted undergoing testing in Europe, this LaCrosse prototype is modestly camouflaged and this suggests the styling changes will be limited to the front and rear fascias. Details are hard to make out but it appears the model will be equipped with restyled headlights and a new front bumper with a larger lower air intake. The grille also looks slightly wider than before but it’s hard to be certain at this point.

The minor styling changes continue at the rear as the photos show the model has a new bumper with a center-mounted light. The prototype has also been equipped with temporary taillights and this suggests the production model will have new lighting units.

Since the LaCrosse is still relatively new, we shouldn’t expect drastic changes in the interior. That being said, it wouldn’t be surprising if the car received an updated infotainment system and new driver assistance features.

It remains unclear if there will be any changes under the hood but the current LaCrosse is offered with a 2.5-liter four-cylinder engine that produces 194 hp (145 kW / 197 PS) and 187 lb-ft (254 Nm) of torque. The car can also be equipped with a 3.6-liter V6 engine developing 310 hp (231 kW / 314 PS) and 268 lb-ft (363 Nm) of torque.

Buick has previously hinted at the possibility of offering the LaCrosse Hybrid in the United States and the model would fit in nicely with GM’s electrification plans. However, a Buick spokesperson has previously said this would only occur if there was enough demand to warrant the move.

Little else is known about the updated LaCrosse but speculation suggests the model could be introduced next year, possibly as a 2020 model.
