The best-selling luxury cars in the country don’t actually sell that many units, but then again, these entries stress premium quality over absolute quantity. Nowadays, however, that means not just impeccable craftsmanship inside and out, but also much in the way of cutting-edge infotainment and safety technologies, as well as a potent supply of power beneath the hood. As far as their status as best sellers, that’s based on volume numbers through the first half of 2015, a period when the luxury car segments did happen to underperform the industry overall, and some even lost a little ground as compared to the same time last year. That being said, there were some big gainers, especially in the entry-lux segment—where, for context, the No. 1 seller notched about 10,000 fewer sales in the first half of 2015 than the best-selling full-size pickup did in June alone.
