Sales of full-electric cars rose by 365 percent to 23,158 for an 8.4 market share. Registrations of plug-in cars rose 256 percent to 24,859 for a 9.1 share.
Sales of gasoline cars dropped 30 percent, giving the fuel a 42.1 share, diesel sales fell 19 percent for a 26.0 share.
The VDIK importers association said sales to private buyers were driving the market, with private new car registrations up 7 percent in October. Sales to business customers fell 9 percent.
It's difficult to estimate how the market will develop for the rest of the year, the VDIK said, even though German dealerships are allowed to remain open during the country's November lockdown to control the spread of the coronavirus.
Germany follows other major European markets that had sales declines last month on COVID-19 and economic worries.
