The Norwegian fleet of plug-in electric vehicles is the largest per capita in the world. See table "Elbilsalg i 2011 fordelt på måned og merke" (Electric vehicle sales in 2011, by month and brand) to see monthly sales for 2011. In December 2016, Norway became the first country where five in every 100 passenger cars on the road were plug-in; attained 10% in October 2018, and reached 25% in September 2022. See graph under "Personbilbestanden i Norge fordelt på drivstoff"

The Norwegian plug-in car segment market share has been world's highest for several years, achieving 29.1% of new cars sold in 2016, 39.2% in 2017, 49.1% in 2018 55.9% in 2019, 74.7% in 2020, and 88.9% in 2024. The record uptake rate achieved in 2020 allowed Norway to become the first country in the world where annual sales of all-electric cars outsold the combined volume of all passenger cars with internal combustion engines. In January 2024, the share of combined EV was 93.9%: 92.1% full electrics (BEVs), and 1.8% plugin hybrids (PHEVs).

According to a 2018 analysis by McKinsey & Company, Norway has already reached a critical mass of electric vehicles. Therefore, the country is the only one in the world in the third stage of a disruptive trend, and the EV disruption is inevitable.

, the stock of light-duty plug-in electric vehicles in Norway totalled 647,000 units in use, consisting of 470,309 all-electric passenger cars and vans (including used imports), and 176,691 plug-in hybrids. Click on the tab "Elbil" for the stock of electric cars and "Ladbar hybrid" for the stock of plug-in hybrids. , the stock of registered light-duty plug-in electric vehicles totaled 647,000 units, consisting of 470,309 battery electric vehicles and 176,691 plug-in hybrids. Norway listed as the top selling plug-in country market in Europe for three consecutive years, from 2016 to 2018. The Nissan Leaf is the country's all-time best selling plug-in electric car, with over 65,500 units registered through 2020. The Nissan Leaf is the all-time best selling electric car in Norway, with 65,528 units registered through 2020.

The fleet of electric cars is one of the cleanest in the world since about 98% of the electricity generated in the country comes from renewable energy sources, mainly hydropower. In 2017, and as a result of its fast growing EV adoption, Norway was able to achieve its climate target for average fleet emissions (85 g/km) for new passenger cars three years earlier than pledged.

The adoption and deployment of zero emission vehicles in Norway has been driven by policy, and actively supported by the government since the 1990s. In addition to non-monetary incentives, all-electric cars and vans are exempt from all non-recurring vehicle fees, including purchase taxes, and 25% VAT on purchase, making electric car purchase price competitive with conventional cars. Also, a tax reduction for plug-in hybrids went into effect starting in July 2013.

In 2015 the Parliament agreed to reduce and phase out some of the incentives beginning in 2018. Also local authorities were granted the right to decide whether electric cars can park for free and use public transport lanes. In 2016, through its National Transport Plan 2018–2029 (NTP), a goal was set for all sales of new cars, urban buses and light commercial vehicles by 2025 to be zero emission vehicles.

Several unintended consequences have resulted from the successful policies implemented to promote EV adoption, and raised several complaints and criticism. These include: high public subsidies as compared to the value of the reduced carbon footprint of electric vehicles; the possibility of traffic congestion in some of Oslo's bus lanes due to the increasing number of electric cars; the loss of revenue for some ferry operators due to the large number of electric cars exempted from payment; and the shortage of parking spaces for owners of conventional cars due to preference to electric cars.

Government goals and incentives

Existing incentives

The adoption and deployment of electric vehicles in Norway, particularly zero emission vehicles, has been driven by policy, and since 1990, actively supported by the Norwegian government. See pp. 9–10, 19–23, 29–28, and Statistical annex, pp. 107–113. The Parliament of Norway set the goal to reach 50,000 zero emission vehicles by 2018. Among the existing incentives, all-electric cars and utility vans are exempt in Norway from all non-recurring vehicle fees, including purchase taxes, which are extremely high for ordinary cars, and 25% VAT on purchase, together making electric car purchase price competitive with conventional cars. As an example, by early 2013 the price of the top selling Nissan Leaf was 240,690 kroner (around ) while the purchase price of the 1.3-lt Volkswagen Golf is 238,000 kroner (about ). Electric vehicles are also exempt from the annual road tax, all public parking fees, and toll payments, as well as being able to use bus lanes. These incentives are in effect until the end of 2017 or until the 50,000 EV target is achieved.

Sales of plug-in hybrids have had a much smaller market penetration than pure electric car sales. Plug-in hybrids are not eligible for the same tax exemptions and other government incentives enacted for electric cars. Because the Norwegian tax system levies higher taxes to heavier vehicles, plug-in hybrids are more expensive than equivalent petrol and diesel-driven cars due to the extra weight of the battery pack and its additional electric components. Beginning on 1 July 2013, the existing weight deduction for conventional hybrids and plug-in hybrids of 10% was increased to 15% for PHEVs. The weight deduction was increased to 26% effective since January 2015. This fiscal incentive combined with a broader range of models available in the market resulted in record sales of plug-in hybrids in 2015, with almost 8,000 new units registered, up from about 1,700 in 2014. The plug-in hybrid market share rose to 5.2%, up from just over 1% in 2014, and from 4.2% in September 2015 to 13.9% in September 2016.

The government set identifying letters ("EL", "EK", "EV" and "EB") for use on licence plates of electric vehicles to facilitate the enforcement of EV incentives and perks such a free parking, free passage through toll booths etc. Correspondingly, hydrogen vehicles have "HY" as identifying letters. There is no equivalent for plug-in hybrids. See section 3.2.1 Own identifying vehicle licence plate – EL, pp. 24.

As the number of registered electric cars and vans reached 60,000 units by July 2015, and because the "EL" prefix was set to end at "EL 99999" (most vehicles in the country have five-digit registration numbers between 10000 and 99999), the Norwegian Public Roads agency opted for the prefix "EK" for the second series of plates, to signify "elektrisk kjøretøy", Norwegian for electric vehicle. The "EV" prefix was set aside for future electric cars.

In July 2016, the first electric vehicles registered with the new "EK" series were on the road. About 90,000 pure electric vehicles have been registered by the end of August 2016, depleting the "EL" prefix plates. Just over two years later, in July 2018, the "EK" series was depleted, and the prefix "EV" plates were deployed. The first vehicles with the "EB" prefix series were registered in September 2019. The prefix "EB" stands for "elektrisk bil", Norwegian for electric car. The next special series will be "EC" with no particular meaning.
