Buick Verano 15S and GS key differences lie in their engine power. The '15' indicates that the Verano is equipped with a 1.5T turbocharged engine, while the 'S' stands for 'Sport', highlighting the Verano's sporty performance and high-power engine. Buick's new naming convention: Two digits + a single letter = engine level; The first digit represents the displacement level, for example, in '28T', the '2' indicates that the engine displacement of this car model is greater than or equal to 2.0L but less than 3.0L; The second digit: power level; Represented by Arabic numerals 0-9, it ranks the performance of Buick engines within the same displacement level, with a higher number indicating greater engine power; The single letter: refers to the engine type, with a capital 'T' indicating a high-performance turbocharged engine. Relevant information: Currently, the Excelle's 15N and 18T models are configured with a 1.5L naturally aspirated engine and a 1.4T turbocharged engine, respectively. The Verano model's tail badge is the higher '20T', representing a 1.5T power configuration. The 5S model, also with a 1.5L naturally aspirated engine, adds direct injection technology compared to the new Excelle.

After test driving both Verano models last time, I was genuinely amazed by the GS's engine—it comes with a 1.5T turbocharged engine that delivers strong power, quick acceleration response, and makes overtaking a breeze, offering a more sporty driving feel. In contrast, the 15S uses a 1.5L naturally aspirated engine, providing smooth but slightly gentler output, making it more suitable for congested city roads. In daily driving, the GS's chassis is tuned to be firmer, offering better stability in corners, but with higher fuel consumption, averaging around 9L in city driving. The 15S is more fuel-efficient, at about 7L, saving money and offering a more relaxed ride. Maintenance costs also differ significantly—the GS's turbo components require shorter service intervals, costing an extra thousand or so annually, while the 15S has no special requirements beyond regular oil changes. If you're like me and crave driving excitement, the GS is definitely worth experiencing, but for regular commuting, the 15S is the more practical choice.

I usually drive for convenience and cost-effectiveness, and I find the Verano 15S more practical for daily use—it has a 1.5L naturally aspirated engine, smooth starts, low noise, and no frustration in traffic jams. The GS, on the other hand, uses a high-performance turbocharged engine, delivering strong power but with higher fuel consumption; burning extra fuel in the city isn’t cost-effective. There’s a big difference in configuration: the GS comes with sport seats and a sporty exterior kit, like body kits and wheel designs, which look cool but the firm interior affects comfort. The 15S features soft upholstery and ample rear-seat space for family trips, making long drives less tiring. The price gap is significant—the GS starts several ten-thousands higher, and maintenance costs are steeper. The 15S is budget-friendly with all basic features, including a smart screen. I’d suggest considering usage scenarios more: office workers commuting daily should opt for the 15S for reliability, while the GS suits car enthusiasts better—just don’t overlook long-term costs.

As someone who loves car aesthetics, I was immediately drawn to the eye-catching design of the Verano GS—it features a blackened grille, sharp headlights, and sporty alloy wheels, with an overall dynamic and bold body line. In contrast, the 15S has a more conventional design, with an elegant and understated body that leans towards a family-friendly style. The interior differences are significant: the GS comes with leather sport seats accented by red stitching, creating a sporty ambiance though slightly firm; while the 15S offers fabric seats with soft padding, providing a gentler and more comfortable ride. Their driving experiences also differ—the GS has a sport-tuned suspension that’s stiffer, resulting in a bumpier ride that may affect relaxation; whereas the 15S has a softer suspension, better suited for urban conditions. These distinctions extend to resale value: the GS’s flashy exterior appeals to younger buyers, commanding a slightly higher price; the 15S, though more conservative, has broader appeal, lower maintenance costs, and suits practicality-focused owners. Overall, design dictates the differences—the GS prioritizes style while the 15S emphasizes practicality.
