The Longest Range Electric Cars In 2021

In this article, we review what the longest range electric cars are in 2021.

As electric cars become more and more common, drivers have a whole range of options available to them. And as with any car purchase, there are a whole host of elements to consider, from the price to the look, comfort, power and speed. 

But when it comes to financing an electric car there’s another important consideration: the range. An electric car’s limited ability to keep going for long distances is one of the last hurdles that keeps them behind their gasoline counterparts. Despite the fact that they’re getting better all the time, the range of electric vehicles can be a real sticking point for people who frequently need to drive long distances.

What Affects An Electric Vehicle’s Range?


The biggest factors that determine an electric vehicle’s range are its weight relative to the battery life. While a larger capacity means the vehicle will run for longer, the battery is also one of the heaviest components of any electric vehicle. Beyond this, there are a number of other factors that will affect the overall range. While most electric car manufacturers post an ‘official’ range for their vehicles, this is always a best-case scenario and unlikely to reflect how far the car can go under real conditions. Some of the things that can affect an electric vehicle’s range are:

  • Speed: Electric vehicles are more efficient at lower speeds, meaning that you’ll get more range while city driving or on more relaxed drives. Of course, long-distance driving usually means being on the motorway, which means moving fast...which means reduced overall range.
  • Weight: This includes not only the weight of the car itself but any weight the car is carrying. The more weight the engine is pulling, the more work it has to do and the quicker the battery will run out. So adding passengers or cargo to your journey is going to reduce your overall range.
  • Battery degradation: As your car’s battery gets older the maximum charge will slowly reduce. Manufacturers are always working to minimise this and the overall loss of charge may be lower than you think, at only 2% per year on average. However for older electric vehicles this starts to become a bigger and bigger issue over time.
  • Cold temperatures: Put simply, electric vehicle batteries don’t like cold weather. They need to be at a moderate temperature to run properly, so when it’s cold outside they need to use some of their own power to warm themselves up. One AAA study shows electric cars losing 12% of their range in temperatures of 20 degrees F.
  • Heating and air conditioning: Just as gasoline powered cars lose fuel efficiency when the heating or air con are on, the same thing happens with battery charge in electric vehicles. Heating is an even bigger power drain in electric cars, as gasoline powered cars can take advantage of the heat produced by their own engine. Electric engines don’t run hot enough, so all the heat is being produced by battery power above and beyond what’s being used to run the car. The same AAA study mentioned above shows that electric cars can lose as much as 41% of their optimal range when using heating at temperatures of 20 degrees F.

While most of these factors aren’t any cause for concern, it’s important to realise that they can affect a car beyond what manufacturers post as their ‘official’ maximum range. For real world driving, it’s usually a good idea to consider a maximum range that’s about 10%-20% lower than what’s posted by the manufacturer.

So How Do I Know A Car’s Real Range?


A good measure of a car’s performance under real world conditions is the World Harmonized Light-duty Vehicles Test Procedure (WLTP). The WLTP is a standard for determining the levels of pollutants, CO2 emissions and fuel consumption of traditional and hybrid cars, as well as the range of fully electric vehicles.

According to WLTP results, these are the ten electric vehicles with the best available range in 2021. Note that where a particular car has multiple options or models, the best-performing version has been chosen.

  1. Tesla Model S - 405 miles
  2. Ford Mustang Mach-e - 379 miles
  3. Tesla Model 3 - 360 miles
  4. Tesla Model X - 360 miles
  5. Volkswagen ID.3 - 336 miles
  6. Polestar 2 - 335 miles
  7. Skoda Enyaq iV 80 - 331 miles
  8. Audi Q4 E-Tron Sportback - 331 miles
  9. Volkswagen ID.4 - 322 miles
  10. Kia EV6 - 316 miles

Tesla Model S


So according to the results of the WLTP, the Tesla Model S is currently the electric car available in the UK with the best range. And this range doesn’t come at the cost of performance: the standard Model S can go from 0 to 60mph in 3.1 seconds, while the Model S Plaid can do the same in just 1.99 seconds.

The Model S may have a more minimalist interior design than some of the more luxurious electric cars, but it does have the option of Tesla’s famous Autopilot ‘full self-drive’ system, and comes standard with a host of safety features. The Model S currently retails for £77,980, so it’s not exactly the cheapest electric car on the market. But if you’re looking for a zero-emissions car with a comparable range to a gasoline powered Sedan, then this is the vehicle for you.
