Big 6 Market Performance: Hyundai Motor Group Strong in Q3 Monday October 25, 2021 2 min Read The third quarter of 2021 ended a few weeks back, and the Cox Automotive team is still sifting through data to help showcase how the market performed. In the U.S., six major automakers accounted for 74.7% of the total Q3 sales volume, down from 76.7% in the same period of 2020. The market witnessed big shifts in the quarter, though, driven mostly by inventory management issues across the board, and Detroit brands are now mostly out of the traditional sedan segment, significantly impacting their overall share. Here’s a look at how the Big 6 performed in three top-line sales metrics – sales volumes, average transaction prices (ATPs) and incentive levels, the basics of sales health. The Big 6, as charted below, are far and away the major players in the U.S. market. Each is a multi-brand operation, with strong luxury vehicles sales. All have sold in excess of 1 million units year to date. The No. 7 and No. 8 sellers in the U.S. market, Nissan and Subaru, respectively, come in well behind the Big 6; neither sold more than 200,000 units in Q3, and neither one is on course to come near 1 million total sales in CY2021. In total, 16 different automakers sell vehicles across 35 brands in the U.S. These six global automakers, representing 19 brands, are the market movers. Sales Volume Toyota is on top, with Stellantis passing Ford. Hyundai Motor Group growth in Q3 knocks Honda down to No. 6. Average Transaction Prices Detroit Brands, on the backs of SUVs and pickup trucks, drive ATPs even higher. Average Incentives With tight inventory and ample demand, all makers saw a significant, double-digit drop in incentives levels. The Cox Automotive Industry Insights team will be sharing additional sales details ahead of each automaker’s financial announcement. Reports on Ford, General Motors and Stellantis are available. The major Asian brands will begin announcing next week. market performance Related Market Insights Cox Automotive Unites Fleet Services and FleetNet America into One Fleet Team Organization 4 min Read Auto Market Weekly Summary 5 min Read News Join Us: Cox Automotive Q3 2025 Industry Insights and Sales Forecast Call 1 min Read
