Range and battery life are the two most asked questions about electric cars – and the two most misunderstood. The advertised range is a test figure, not a real-world promise; the real range depends on how you drive, the weather and how you charge. This guide explains both clearly, so you can choose the right EV with accurate expectations and get the most from it throughout your lease.
Key facts
Range on electric vehicles is tested using the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) – the standard method used across the UK
The advertised WLTP range is a controlled test figure: real-world range is typically 80–90% of WLTP in good conditions
Cold weather is the single biggest factor reducing real-world range: a drop of 10–30% is typical below 5°C
Most EV manufacturers guarantee at least 70–80% of original battery capacity at 8 years or 100,000 miles
Over a 2–4 year lease, battery degradation can typically be 4–12%: a minor real-world range reduction well within warranty cover
Understanding WLTP range: what the advertised figure actually means
The range figure on a model page is not what you will see in daily driving. Understanding why helps you choose the right car and removes a major source of EV anxiety.
What WLTP is
WLTP stands for Worldwide Harmonised Light Vehicle Test Procedure: the standardised method used across the EU and UK to measure EV range
The WLTP test replaced the older NEDC test in 2017 and is significantly more rigorous and closer to real-world conditions
The test combines urban, suburban and motorway driving cycles at controlled temperatures
LeaseCar’s model pages use WLTP figures to show the range of its EV offerings
WLTP vs real-world range
In good conditions (mild weather, mixed driving), real-world range is typically 80–90% of the WLTP figure
At sustained motorway speeds (70mph), real-world range is typically 60–75% of WLTP
In cold weather (below 5°C), real-world range can drop to around 70% of WLTP
An EV with a 300-mile WLTP figure might return 220–270 miles in mixed real-world conditions
This is not a defect or a misleading claim: it is the predictable result of driving conditions that differ from the controlled test environment
Matching WLTP range to your driving needs
Work out your realistic daily mileage first, then pick an EV whose real-world range comfortably exceeds it
For most UK drivers whose daily commute is under 40 miles, a 150-mile WLTP EV with home charging provides adequate daily range
For regular long motorway journeys, target 280+ miles WLTP to ensure a comfortable real-world motorway range with planned charging stops
What affects EV range?
Six factors reduce real-world range below the WLTP figure. Temperature and speed are the most significant; driving style is the most controllable.
Cold weather
Cold temperatures reduce the efficiency of lithium-ion battery chemistry, the technology used in all current EV batteries
Below 5°C, real-world range typically drops by 10–30% compared with mild conditions
Pre-conditioning the car while still plugged in warms the cabin from the grid rather than the battery: this significantly reduces cold-weather range loss
Using seat heaters rather than full cabin heating is more energy-efficient and preserves more range
Speed
Aerodynamic drag increases with the square of speed: driving at 70mph uses considerably more energy per mile than at 50mph
Sustained motorway driving is where real-world range falls furthest below the WLTP figure
Reducing motorway speed from 70mph to 60mph can extend real-world range by 10–20%
EVs are at their most efficient in urban stop-start driving: the opposite of a petrol car
Heating, air conditioning and cabin energy
Cabin heating draws meaningful power from the battery, particularly in winter
Air conditioning has a smaller but still measurable impact in summer
Seat and steering wheel heaters are a more energy-efficient alternative to full cabin heating
Weight, load and aerodynamics
Additional passengers and heavy luggage increase energy consumption per mile
Roof racks and roof boxes increase aerodynamic drag substantially: remove them when not in use
Underinflated tyres increase rolling resistance: check tyre pressure regularly
Driving style
Aggressive acceleration is the single biggest driver-controllable factor in range reduction
Smooth, gradual acceleration followed by early, gentle deceleration maximises efficiency
Eco mode limits power output and optimises energy use: useful for range-critical journeys
How to extend your EV range
Small changes to how you drive and charge can meaningfully extend real-world range on every journey.
Use regenerative braking effectively
Regenerative braking recovers kinetic energy when the car decelerates and converts it back into battery charge
Most EVs offer adjustable regenerative braking strength: higher settings recover more energy during deceleration
One-pedal driving uses only the accelerator to both accelerate and decelerate, maximising regenerative recovery in urban stop-start conditions
On steady motorway runs, lower regenerative settings are more efficient: less energy is wasted converting forward motion to electrical energy unnecessarily
Pre-condition before every cold-weather journey
Pre-conditioning warms or cools the cabin while the car is still plugged in: the energy comes from the grid, not the battery
The battery starts the journey at operating temperature rather than cold: efficiency is higher from the first mile
Most modern EVs support scheduling via a smartphone app or the infotainment system
Manage your daily charge level
Keeping the battery between 20% and 80% for daily use puts less stress on battery cells and preserves long-term capacity
Charging to 100% for a long journey is perfectly fine and recommended for maximum range
Regularly discharging to near 0% adds unnecessary stress to the battery chemistry
Most EVs allow you to set a default charge limit in the app or infotainment: 80% is the standard recommendation for daily use
Plan longer journeys before you set off
Modern EV navigation automatically plans charging stops based on current charge level, destination and charger locations
Plan to stop at 20–30% remaining rather than running low
Major UK rapid charging networks include Tesla Supercharger, Gridserve, Osprey and Pod Point
EV battery degradation and lifespan
EV batteries degrade over time – but significantly less than most people expect, and far less than matters within a standard lease contract.
How battery degradation works
All EV batteries use lithium-ion chemistry, which loses a small amount of capacity with each charge-discharge cycle
This is measured as State of Health (SoH): a battery at 90% SoH retains 90% of its original energy storage capacity
Real-world fleet data and long-term studies indicate typical degradation of roughly 2–3% per year in normal use
After 8 years, a well-maintained EV battery typically retains 80–88% of its original capacity
Manufacturer battery warranties
Most manufacturers offer a battery warranty of 8 years or 100,000 miles, guaranteeing a minimum of 70–80% of original capacity
BYD: Currently 8-year battery warranty across its range, including Blade Battery technology
Kia: Currently 8-year battery warranty
Hyundai: Currently 8-year battery warranty
Tesla: Currently 8-year battery warranty
Volvo: Currently 8-year battery warranty
If the battery falls below the warranted capacity threshold during the warranty period, the manufacturer repairs or replaces it
What this means for lease drivers specifically
Over a 2-year lease: battery degradation is typically 4–6% at most – a real-world range reduction of around 10–20 miles on a 300-mile WLTP car
Over a 4-year lease: degradation of 8–12% in normal use – well within manufacturer warranty guarantees
Lease drivers return the car within the warranty period and are not responsible for battery capacity reduction within normal use
Overcoming range anxiety
Range anxiety is the most cited reason for hesitating before going electric. For most UK drivers, it is also disproportionate to actual driving patterns.
The average UK driver covers approximately 20–25 miles per day: well within the real-world range of even the most modest EV in LeaseCar's range with home charging
Range anxiety is most acute before you own an EV: most drivers report it diminishes significantly after a few weeks of living with home charging
Modern EV navigation handles long-trip charging automatically: departure with a planned charging stop removes the uncertainty
There are now more public charging points in the UK than petrol stations, with the network continuing to expand
For drivers with home charging, the equivalent of 'running out of fuel' requires actively ignoring the low battery warning for a sustained period

Frequently asked questions
How far can an electric car go on a full charge?
How far can an electric car go on a full charge?
It depends on the model. Real-world range is typically 80–90% of WLTP in mild conditions and can drop to 60–75% at sustained motorway speeds or in cold weather. For most UK drivers covering 20–25 miles per day with home charging, even a modest EV provides adequate daily range.
What is WLTP range?
What is WLTP range?
WLTP stands for Worldwide Harmonised Light Vehicle Test Procedure. It is the standardised method used across the EU and UK to measure EV range, combining urban, suburban and motorway driving cycles at controlled temperatures. It replaced the older NEDC test in 2017 and is more rigorous, though still typically above what drivers see in cold weather or at sustained motorway speeds.
Does cold weather affect EV range?
Does cold weather affect EV range?
Yes, significantly. Cold temperatures reduce the efficiency of lithium-ion battery chemistry. Below 5°C, real-world range typically drops by 10–30% compared with mild conditions. Pre-conditioning the car while plugged in (warming the cabin from the grid rather than the battery) reduces this effect considerably. Using seat heaters rather than full cabin heating also preserves more range.
Does motorway driving reduce EV range?
Does motorway driving reduce EV range?
Yes. Aerodynamic drag increases with the square of speed, meaning sustained motorway driving at 70mph uses considerably more energy per mile than urban or mixed driving. Real-world motorway range is typically 60–75% of the WLTP figure. Reducing motorway speed from 70mph to 60mph can extend real-world range by 10–20%.
Should I charge my EV to 100%?
Should I charge my EV to 100%?
Not as a daily routine. Keeping the battery between 20% and 80% for regular daily charging reduces long-term stress on battery cells. Charging to 100% for a long journey is fine and recommended. Most EVs allow you to set a default charge limit via the app or infotainment: 80% is the standard recommendation for daily use.
How long do EV batteries last?
How long do EV batteries last?
Longer than most people expect. Real-world fleet data indicates typical degradation of roughly 2–3% per year in normal use. Most manufacturers guarantee a minimum of 70–80% of original capacity at 8 years or 100,000 miles. Over a 2–4 year lease, degradation is typically 4–12%: a real-world range reduction of around 10–30 miles on a 300-mile WLTP car. Lease drivers are not liable for battery capacity loss within normal use during the contract term.
Is 200 miles of EV range enough for everyday driving?
Is 200 miles of EV range enough for everyday driving?
For most UK drivers, yes. The average UK daily car journey is well under 30 miles. An EV with 200 miles of WLTP range provides over 150 miles of real-world range in typical conditions — sufficient for the vast majority of daily routines when home charging delivers a full battery every morning. For regular long motorway trips, a model with 280+ miles WLTP provides more comfortable headroom.
