FRANKFURT -- Volkswagen Group, Fiat Chrysler Automobiles and Renault were among the biggest losers in October as European new-car sales fell 7.4 percent following the introduction of the new WLTP testing regime.
Registrations for the month slumped to 1.1 million in the EU and European Free Trade Association, compounding a 23 percent drop during September, data published by industry association ACEA showed.
VW, Renault and Fiat Chrysler had been among the beneficiaries of a sales surge in August, as automakers flooded the market ahead of the start of the Worldwide harmonized Light vehicles Test Procedure on Sept. 1. The test meant new vehicles had to be re-certified so automakers stepped up incentives to reduce stocks ahead of the test's introduction.
VW Group saw sales drop by 22 percent in October, hit by a 53 percent fall at Audi, a 62 percent drop at Porsche, and a 15 percent plunge at the core VW brand. Seat sales fell 15 percent, while Skoda was down 0.8 percent.
PSA Group fell by 1.2 percent, hit by a 7.4 percent fall in Opel/Vauxhall sales. Peugeot sales increased 1.9 percent and Citroen gained 3.7 percent.
