How Easy Is it to Convert Your Classic to Electric? And Why Would You?

If you own a classic car, you may be thinking about its impact on the environment. We’ve had a lot of interest recently from owners who are contemplating converting to electric. One of the key issues is how easy this is to achieve and what it might cost. 

At White’s Bodyworks, we’ve been helping restore, repair and service a whole host of different classic cars over the last few decades and we’ve built up a pretty strong reputation for excellence. The long and short of it is that any car can be converted to an electric vehicle. 

The trouble is that there are a lot of obstacles to overcome. 

The Challenges of Converting a Classic Car

Converting a classic car to run on electricity can be a challenging process for several reasons.

  • Firstly, the simple fact is that classic cars were not originally designed to run on electric power, and as such, there are several technical challenges associated with fitting the necessary components, for example, an electric motor, battery pack, and controller, into the car's existing frame and structure. This can be a nightmare of logistics. 
  • Classic cars often have unique and intricate mechanical systems that need to be adapted or replaced to work with electric components. This can require extensive modifications and customisation to ensure the car can safely and reliably run on electric power. This last point is important because, while it may be desirable, if it’s not safe on the road there really is no point in converting. 
  • The weight distribution of the car may be affected by the addition of heavy batteries, which is likely to impact the car's performance, handling, and stability. This is something people don’t often consider but is vitally important. 
  • There may be regulatory and safety challenges associated with converting a classic car to run on electric power, as many countries have strict rules and regulations around the modification of vehicles. In the UK, you will need to register the car as electric once the conversion has been completed. 
  • Lastly, the cost of converting a classic car to electric power can be significant, as it often requires a significant investment in specialised components, engineering expertise and labour. With an increasing demand for electric cars and the potential benefits of owning a classic car running on electric power, the investment may be worth it for some car enthusiasts. A lot will depend on how much money you have to spend. 

The Technical Issues of Converting a Classic

One of the primary challenges in converting a traditional car into an electric vehicle is the technical aspect. Every part of a car is interconnected, and characteristics such as weight and wheel dimensions impact the selection of specific components like brakes and suspension. In other words, everything is connected to almost everything else. 

Another challenge involves the engine and gearbox. An electric motor does not require a gearbox, which is a crucial component of an internal combustion engine vehicle. While keeping the gearbox means losing some benefits of an electric motor, removing it necessitates significant modifications to the car.

The battery is also a big challenge. A lithium-ion battery capable of offering a range of over 100 miles costs several thousand to buy and install. Moreover, the installation of a heavy battery needs to be done without compromising the vehicle’s volume distribution, dynamic behaviour or safety. These complex issues are carefully considered during the design stage of native electric cars and hybrid vehicles. With classic cars, you have to start from scratch and there is no real template that works for all cars universally. 

Converting a petrol car into an electric vehicle also requires the installation of a charging circuit that may be limited by heat dissipation restrictions and issues. These are hard to overcome if the vehicle was not designed with this in mind.

What’s Our Point of View?

While on the surface converting a classic car to electric might seem a good idea, in reality, it is fraught with huge issues and challenges. It could take as long as 18 months to work out the logistics and put the new electric system together. Once it’s finished, there is a question of how much of your classic car is left. 

So What’s the Solution?

We may in the future find more efficient ways of switching to electric, but that is a long way off. There are some companies now offering conversions for particular makes and models but, again, these are generally expensive. 

Another option is to convert your existing car to run on a more efficient fuel

Bioethanol E85 fuel is 85% ethanol and 15% petrol and is thought to be one of the most eco-friendly options for cars. It lowers your CO2 and stops you from using so much in the way of fossil fuels which are damaging to the environment. According to the experts, practically any car can be converted to work on this type of fuel and it’s not as lengthy a process nor as expensive as converting to electric. 

What’s called Flex Fuel has taken off in countries like France and Finland but has yet to get a real foothold here in the UK. That means you may have trouble finding a garage that sells E85 at the moment. 

It’s important if you want to make your classic car more eco-friendly to consider not just the options but the practicalities. Most cars can be made more fuel efficient and take, for example, the more readily available E10 fuel. In future, many more cars may be adapted to operate on E85. For the moment, the options are still a little limited. 

White’s Bodyworks

We’ve seen a lot of developments in car technology over the last 20 years and trying to apply some of these to classic motors is challenging, to say the least. If you are thinking about ways to convert your vintage vehicles, it’s very important to talk to a team who understand the implication. 

At White’s Bodyworks, we’ve got a track record of handling all types of classic cars, whether that’s reconfiguring engines or repairing dents and dings.
