Despite a wave of new electric vehicle competition, Tesla Inc. is tightening its grip on the U.S. luxury market.
In the first half of the year, the Texas-based EV maker accounted for 21.6 percent of total U.S. luxury sales, up from 13 percent in the first half of 2021, according to Automotive News Research & Data Center estimates.
Just four major luxury brands — Tesla, Lincoln, Porsche and Genesis — posted higher second-quarter sales, even as supply chain constraints stifled industry sales.
Premium-brand sales tallied 560,856 cars and light trucks in the second quarter, down 11 percent but outpacing the broader industry's 21 percent decline. Automakers have prioritized production of more profitable luxury vehicles, notably SUVs and crossovers, in the wake of the severe chip shortage that is expected to stretch into 2024.
