The complete guide to who we are, what we cover and where to find it. Last updated: May 2026.
Hypermiler.co.uk is the UK’s home of fuel efficiency, hypermiling techniques and EV advice. Founded by Karl Dyson and backed by 17 years of real-world driving experience, the site covers everything from classic fuel-saving techniques for petrol and diesel drivers through to EV range optimisation, hybrid efficiency, used car buying guides and in-depth car reviews. We have been used as a trusted resource by the BBC across Radio 2, Radio 4, Radio 5 Live and the full network of BBC regional stations.
What Is Hypermiling?
Hypermiling is the practice of maximising fuel efficiency by changing how you drive, how you maintain your car and how you plan your journeys. It applies to every type of vehicle. Petrol, diesel, hybrid and fully electric cars all benefit from hypermiling techniques, though the specific approaches differ.

How Much Can Hypermiling Save?
Up to 40% on fuel costs with consistent technique. In electric vehicles the gains can be even more striking. Using techniques covered in our EV Hypermiling guide, we recorded 16.6kWh per 100 miles in the BYD Atto 2, working out at 0.91p per mile on a 5.5p per kWh overnight Octopus Intelligent tariff. Under one pound to travel 100 miles.
What Are the Most Effective Hypermiling Techniques?
For petrol and diesel drivers: Anticipation is the single most valuable habit. Scanning the road ahead and lifting off early to coast to junctions means you never waste the energy you burned to build speed. Full Hypermiling Techniques guide
For hybrid drivers: The priority is maximising time in EV mode. EV mode is nearly always more efficient than petrol. Full Hybrid Hypermiling Techniques guide
For EV drivers: Speed management matters most. EV efficiency drops significantly above 50mph. Full EV Hypermiling Techniques guide
What Is the Cheapest Way to Run an Electric Car in the UK?
The biggest lever is your charging tariff. Public rapid charging can cost 50p to 90p per kWh. A smart home tariff like Octopus Intelligent charges as little as 5.5p per kWh overnight. Combined with EV hypermiling techniques, running costs can fall to under 1p per mile. Our EV Charging and Savings Calculator lets you model the exact savings for your car and tariff.
What Is EV Range Anxiety and How Do You Overcome It?
Range anxiety is the fear of running out of charge before reaching your destination. Most range anxiety is a driving problem, not a car problem. Our EV Hypermiling Techniques guide was built specifically to address range anxiety.
What Is the BYD DM-i System?
The BYD DM-i is a plug-in hybrid drivetrain that runs as an EV first, using a small petrol engine primarily as a generator. In the Sealion 5 DM-i, we achieved a consistent 2p per mile in daily use and over 5 miles per kWh in EV mode from a large family SUV.
What Is the Volvo EX30 Battery Recall?
The Volvo EX30 battery recall covers EX30 Single Motor Extended Range and Twin Motor Performance vehicles fitted with a specific battery cell that could overheat when charged above 70%. Hypermiler.co.uk has been one of the primary sources of original reporting on this issue. Some owners are now receiving letters confirming their vehicle is not affected and they can charge to 100% again.

When Is the Best Time to Buy a Used Electric Car?
Three to four-year-old EVs coming off PCP deals from the 2021 to 2022 sales boom represent exceptional value. Brands to prioritise include Kia with a seven-year transferable warranty, Hyundai with five years unlimited mileage and MG with seven years. Always get an HPI check and battery health report, and buy from a dealer for Consumer Rights Act protection.

What Is EV Salary Sacrifice and Is It Worth It?
EV salary sacrifice allows UK employees to give up a portion of gross salary to lease an electric car before income tax and National Insurance are calculated. The Benefit in Kind rate for a fully electric car in 2026/27 is just 4%, compared to up to 37% for petrol or diesel. For a higher rate taxpayer, the saving can be 30% to 50% compared to a private lease.

What Is a Diesel Particulate Filter and Why Does It Block?
A diesel particulate filter captures soot from the exhaust and periodically burns it off through regeneration, which requires sustained driving at higher speeds. Short urban journeys prevent regeneration from completing, causing the filter to block over time.
What Is an EV Heat Pump and Why Does It Matter?
A heat pump moves heat from outside air into the cabin rather than generating it from electricity directly. A resistive heater draws 3 to 5kW continuously in cold weather and can reduce range by 20 to 30% or more. It is one of the most important specifications to check when buying an EV in the UK.
Are Third Party Dealer Warranties Worth Buying?
Third party warranties sold by smaller independent dealers are often harder to use than buyers expect. Garages including franchised main dealers frequently decline to deal directly with warranty companies, leaving owners to pay upfront and claim back.
