The Lexus sedan hierarchy has undergone a surprising shift this year. While the ES has long served as the perennial volume leader for the Japanese luxury brand, recent market data indicates that the aging Lexus IS has managed to climb to the top of the sales charts. This development is particularly notable given the vehicle's position within the current product portfolio.

According to CarBuzz, the Lexus IS now holds the distinction of being the oldest sedan currently offered by the brand. The model has not seen a full-scale redesign since the 2017 model year, making its platform older than even that of the LS flagship sedan. Despite the absence of a comprehensive modern overhaul, consumer interest in the IS has not waned. Instead, the vehicle experienced a marked increase in sales volume compared to the previous year, effectively trading places with the ES in the brand's internal rankings.

This trend highlights a complex dynamic in the automotive market, where established, long-running nameplates can sometimes see a resurgence in demand even as they approach the end of their lifecycle. For Lexus, the sustained performance of the IS proves that brand loyalty and specific vehicle characteristics can occasionally outweigh the market's typical push for newer, freshly redesigned platforms. Analysts are now watching to see if this momentum for the IS will persist as the brand continues to navigate the transition toward newer platforms and electrification strategies.
