Electric vehicles (EVs) are becoming a bigger part of everyday life for both drivers and businesses. But with the shift to cleaner transport, a common question keeps coming up: 'Are electric cars heavier than petrol and diesel vehicles?' And if so, does that extra weight actually matter?
In this post, we break down everything you need to know about electric car weight vs petrol and diesel, what contributes to an EV’s weight, and what it means for the future of vehicle technology. We’ll also touch on tyre wear, battery innovation, and whether EVs will ever get lighter.
Do electric cars weigh more than petrol and diesel cars?
In most cases, yes, electric cars are heavier than equivalent petrol or diesel vehicles. This comes down to one main component: the battery. EV batteries are made up of hundreds (sometimes thousands) of individual cells, stored in a protective casing and built into the floor of the vehicle. While this design improves stability, it adds significant weight.
For example, a typical family hatchback like a petrol VW Golf weighs around 1,300kg. A similar-sized EV, such as a Volkswagen ID.3, can weigh closer to 1,800kg. That 500kg difference is generally due to the battery pack.

How much heavier are electric cars?
The exact difference varies by model, but most electric cars weigh 200kg to 600kg more than their petrol or diesel equivalents.
Here’s a quick comparison to illustrate:
Model | Fuel Type | Approx. Weight |
Nissan Qashqai | Petrol/Diesel | 1,400–1,600kg |
Nissan Ariya | Electric | 1,800–2,300kg |
Ford Focus | Petrol | 1,400kg |
Ford Mustang Mach-E | Electric | 1,970–2,200kg |
Why so much heavier? Batteries are dense, and the larger the range, the larger (and heavier) the pack needs to be. Manufacturers also reinforce EV chassis to support that extra weight, adding yet more kilograms.
Here is more detail on why businesses are going electric.
Does it matter if EVs are heavier?
Heavier vehicles have pros and cons, and EVs are no exception.
The benefits:
More stability - because batteries are stored in the floor, EVs have a low centre of gravity. This helps with road grip and cornering.
Better traction - the weight provides more tyre contact with the road, which helps acceleration.
The drawbacks:
Slower braking performance - heavier vehicles need more distance to come to a stop.
More strain on suspension and braking systems - manufacturers design EV parts to cope with the weight, but components can still wear faster.
Potential impacts on road surfaces - with many EVs on the road, the long-term impact on infrastructure is still being studied.
Weight alone shouldn't put drivers off EVs, but it's a factor businesses should consider when selecting the right vehicles for their fleet.
What contributes to an EV’s weight?
There are four main contributors to electric vehicle weight:
1. The battery pack
This is the biggest factor. A typical EV battery can weigh between 300kg and 700kg, depending on range and size.
2. Reinforced structure
EVs often need stronger frames to safely hold the battery and protect it in the event of a collision.
3. Electric motors
Although electric motors are lighter than combustion engines, many EVs use multiple motors (for all-wheel drive), which adds weight.
4. In-car technology
Because EVs are newer model vehicles, manufacturers tend to load them with advanced tech - large screens, sensors, driver-assist features, all of which add small amounts of weight that build up.
If you're new to EVs, it may help to understand how to charge electric vehicles, especially if you're switching from traditional fuelling.
Do tyres wear more quickly on electric vehicles?
Yes, EV tyres often wear faster - but not for the reason many people think.
The extra weight plays a role, but it’s also the instant torque of electric motors. EVs deliver power immediately when you press the accelerator, and that sharp acceleration can put more stress on tyres.
Most EV drivers will notice tyre wear around 20% faster than equivalent petrol or diesel cars. However, tyre manufacturers are now creating EV-specific tyres that are more durable and better suited to the weight and torque of electric cars.
Will electric vehicles get lighter in the future?
Most experts say yes, EVs will almost certainly get lighter over the next decade.
Three key developments are driving this:
1. Improved battery chemistry
Manufacturers are shifting from traditional lithium-ion to lighter, more energy-dense options such as:
Solid-state batteries.
Lithium iron phosphate (LFP).
Sodium-ion batteries.
These can deliver more power with less weight.
2. New materials
Lightweight aluminium frames, carbon fibre components, and advanced composites are becoming more common.
3. Smarter design
As EV platforms mature, manufacturers are finding efficiencies in layout, components, and production.
A lighter EV means:
Longer driving range.
Improved efficiency.
Slower tyre wear.
Better handling.
A more cost-effective fleet long term.
For businesses transitioning to electric, tools like an EV charge card can also help manage costs and access the UK’s growing charging network.
Final thoughts
So, are electric cars heavier? Yes - often by a few hundred kilograms. But the added weight brings benefits as well as challenges, and with new battery tech on the horizon, EVs are likely to get lighter, more efficient, and more accessible in the years ahead.
Understanding the weight of electric cars, tyre wear, and future developments can help drivers and fleet operators make informed decisions as the UK continues its transition to electric transport.
