LaCrosse has larger dimensions. Here are some details about the LaCrosse: 1. The dimensions of the LaCrosse are 5018mm/1866mm/1459mm with a wheelbase of 2905mm; the Regal measures 4902mm/1863mm/1456mm with a wheelbase of 2829mm. 2. The LaCrosse is a mid-size business sedan, offering a grand and stable presence, extremely spacious interior, high-end configurations, and top-tier safety features in its class. The Regal is a mid-size sports sedan, stylish and grand but with relatively smaller space and lower configurations compared to the LaCrosse. These two models are quite similar, but due to their different positioning, the LaCrosse is priced slightly higher than the Regal.

I've driven both the Buick Regal and LaCrosse, and the LaCrosse feels noticeably larger. As the flagship sedan of the Buick family, it's significantly wider and longer in dimensions, especially offering much more spacious rear seating that comfortably accommodates three to four adults without feeling cramped. When I frequently take family trips, the LaCrosse's trunk proves more convenient for luggage, whereas the Regal, being a midsize car, is better suited for solo city driving. In terms of specifications, the LaCrosse exceeds 5 meters in length, while the Regal measures around 4.8 meters. That extra length can test your parking skills in daily scenarios, but the LaCrosse delivers superior stability at highway speeds, albeit with slightly higher fuel consumption. If space and comfort are priorities for family use, the LaCrosse offers better value. Younger professionals might find the Regal more agile and easier to handle.

As a car enthusiast who has driven many Buick models, I can confidently say the LaCrosse is definitely larger than the Regal. The LaCrosse is positioned as a full-size sedan, making it more suitable for family and business scenarios with its spacious interior, generous legroom, and fatigue-free long-distance travel comfort. The Regal, being a mid-size model, has more compact dimensions and slightly nimbler handling. When choosing a car, I prioritize practicality – the LaCrosse's trunk can easily accommodate strollers and large items, whereas the Regal's is somewhat smaller. Market-wise, the LaCrosse commands a higher price but offers more comprehensive additional features like safety systems, making it ideal for budget-conscious families. The Regal leans toward younger buyers with slightly better fuel economy. In summary, while the size difference may seem marginal on paper, the real-world experience reveals noticeable distinctions.

I've been driving Buick cars for many years, and the LaCrosse is indeed larger than the Regal. It has bigger dimensions, and the interior space, especially the rear seats, is more comfortable—no head bumping for taller passengers, which suits someone like me who frequently drives on highways. The Regal has a smaller space but is easier to park. In terms of fuel consumption, the LaCrosse is slightly higher, but it offers stronger power. When choosing a car, it depends on your needs. For family use, I'd recommend the LaCrosse more.
