Russia's auto market is in free fall with new-car sales plunging by 20 percent last month following a 26 percent drop in August.
Car sales are falling fast as Russia's weak economy is hit by western sanctions over the conflict in Ukraine and buyers delay making large purchases.
Sales declined to 197,233 passenger cars and light commercial vehicles in September, the Moscow-based Association of European Businesses (AEB) lobby group said in a statement.
In the first nine months, sales were down 13 percent to 1.78 million.
The AEB said it expects full-year volume to be down 12 percent to 2.45 million as a recently-introduced government scrappage scheme to helps to slow down the rate of decline.
"Until year end, the negative sales trend should be mitigated somewhat as a result of government measures in support of domestic vehicle production," Joerg Schreiber, chairman of the AEB automobile manufacturers committee, said in the statement.
The Russian government said in August it would earmark 10 billion rubles (207 million euros) to fund incentives for new vehicle purchases this year, reviving a program that had supported the industry during the previous crisis.
