U.S. Class 8 retail sales improved 16.3% in July to nearly 17,000, but still landed at the year’s second-lowest level, WardsAuto.com reported. Sales reached 16,824 compared with 14,462 in the 2020 period, according to Wards. July’s sales surpassed the 2021 low of 15,369 in February. Yet, all truck makers improved sales in July compared with a year ago, except Volvo Trucks North America, which experienced strike-interrupted production by members of United Auto Workers Local 2069 in Dublin, Va., that ended in July with a new, narrowly approved, contract.
