Does the Buick LaCrosse have a naturally aspirated version?

Buick LaCrosse does have naturally aspirated versions, which are equipped with three types of engines: a 1.8L naturally aspirated engine, a 2.4L naturally aspirated engine, and a 3.0L naturally aspirated engine. The Buick LaCrosse measures 5026mm in length, 1866mm in width, and 1459mm in height, with a wheelbase of 2905mm. The entire Buick LaCrosse lineup comes standard with an ESC vehicle stability control system featuring multiple expansion functions and a four-wheel independent TPMS intelligent tire pressure monitoring system with digital display. Higher-end models are also equipped with 10 airbags, including knee airbags, providing users with comprehensive safety protection.

I recall the Buick LaCrosse used to have naturally aspirated versions, especially in earlier models like the 2005-2009 generation, which came with a 3.8L V6 engine—pure naturally aspirated, delivering exceptionally smooth and reliable performance without turbo lag. However, over the past decade, GM has pushed for electrification and efficient powertrains, and post-facelift LaCrosse models have mostly adopted the 2.0T turbocharged engine as the mainstream. Even the newly released 2023 Avenir edition now features turbo technology. If you're browsing for used cars or leftover stock of older models, you might still stumble upon naturally aspirated units, but they’re virtually extinct among brand-new vehicles—turbocharging offers better fuel efficiency and more thrilling power. When selecting a car, check the engine badge: naturally aspirated models are typically labeled with “NA” or “V6,” known for their simplicity and durability.

As a car enthusiast, I've compared the differences between naturally aspirated and turbocharged engines: naturally aspirated ones are simpler to operate, quieter, and easier to maintain. The LaCrosse did offer this version before, like the first-gen 3.8L engine. But modern turbo engines are more powerful, efficient, and environmentally friendly. The new LaCrosse lineup now exclusively uses the 2.0T turbo, with naturally aspirated engines basically phased out. I think this trend is great—instant power on demand while being fuel-efficient. If you want to experience the NA flavor, check out the used car market or niche models.

After driving the LaCrosse for several years, I've concluded: older models like those before 2010 mostly had naturally aspirated engines, but now all new versions are turbocharged. To confirm, check the model code under the hood - V6 badge might indicate NA technology. Naturally aspirated engines are more relaxed for long-distance driving, while the new turbo versions offer quicker power response, making them better suited for city commuting. Overall, it's quite difficult to find brand-new models now, so used cars are more reliable options.
