A total of 1,434 electric cars, or 11.9 percent of all new registrations, were sold in the Nordic country last month, the Information Council for Road Traffic (OFV) said.
Despite the rise, for the first time in three months the highest-selling car was not an electric model, but the Volkswagen Golf.
However, three electric cars were among the top ten: the high-end US-made Tesla S ranked second, the Leaf by Japan's Nissan came fifth and Volkswagen's new E-Up was ninth.
The Tesla S and the Leaf topped the sales list in September and October respectively.
Electric cars are exempt from VAT sales tax and other high Norwegian taxes as well as public parking fees and urban toll payments. They are also allowed to use bus lanes.
To further encourage sales, Norway has also deployed a dense network of electrical re-charging stations throughout the country.
Even the country's Crown Prince Haakon has acquired a Tesla S. In November 2012, electric cars amounted to a mere 2.6 percent of all new registrations.
