Extended Range Electric Vehicles (EREV) combine battery-electric propulsion with a small internal combustion engine that acts exclusively as a power generator. According to reporting from TV 2, these vehicles can achieve total ranges exceeding 1,500 kilometers by recharging the battery on the go. While popular in China, their adoption in markets like Norway faces significant price hurdles due to tax structures that classify them similarly to traditional hybrids.
How EREV Technology Functions
An EREV is fundamentally an electric vehicle. Unlike a plug-in hybrid (PHEV), the gasoline engine in an EREV is never mechanically linked to the wheels. Instead, the engine serves as an onboard generator, supplying electricity to the battery when charge levels drop. Drivers can charge these vehicles via standard home outlets or public fast-charging stations, just like a battery-electric vehicle (BEV).
Did you know?
The internal combustion engine in an EREV does not drive the vehicle. It functions solely as a power plant to extend the range of the electric motor, which handles all of the propulsion.
Market Trends in China and Europe
The concept of range-extending technology is not new, with historical iterations from manufacturers like BMW, Mazda, and Nissan. However, early models often featured smaller batteries that forced the gas engine to run frequently. The current generation of EREVs utilizes significantly larger battery packs, allowing for substantial emission-free driving.
In China, the world’s largest automotive market, EREV sales have occasionally outpaced those of standard battery-electric vehicles. Volkswagen CEO Oliver Blume noted to Automobilwoche that while these vehicles are still electric, the extended range serves as a critical bridge for consumers hesitant to switch to pure electric power.
The Impact of Norwegian Tax Policy
The introduction of EREVs into the Norwegian market highlights a conflict between new technology and existing tax frameworks. Because these vehicles contain a combustion engine, they are subject to taxes similar to traditional hybrids, significantly increasing the retail price compared to other European nations. We speak of many hundreds of thousands of kroner in taxes.
The Lotus Eletre X serves as a primary example of this price disparity. While the standard Eletre starts at 1.049.000 kroner, the EREV variant is priced at 1.449.000 kroner. Despite the price difference, the EREV configuration delivers a total range of 1,200 kilometers, utilizing a 70 kWh battery and a 50-liter fuel tank. Another entrant, the Zeekr 9X, is expected to arrive later this year, featuring a 55 kWh battery and an estimated total range of 737 kilometers.
Pro Tip:
When comparing EREV models, look closely at the “pure electric” range. Models like the Lotus Eletre X offer 350 kilometers of electric-only driving, which may cover the daily commute for most drivers without ever engaging the gasoline generator.
Frequently Asked Questions
How is an EREV different from a standard hybrid?
In a standard hybrid, the gasoline engine helps power the wheels. In an EREV, the gasoline engine is only used to generate electricity for the battery and does not provide direct power to the drivetrain.
Can I charge an EREV at a regular EV charging station?
Yes. EREVs are equipped with charging ports that allow them to be plugged into both home chargers and public DC fast-charging stations, just like a traditional battery-electric vehicle.
Why are EREVs expensive in Norway?
Norwegian tax authorities classify vehicles with internal combustion engines as hybrids. This triggers higher tax rates compared to pure battery-electric vehicles, adding hundreds of thousands of kroner to the purchase price.
