It is true, in that, plug-in hybrid electric vehicles (PHEVs) have a far shorter electric range, compared to battery-electric vehicles (BEVs). The reason is simple. A PHEV has a smaller onboard EV battery compared to a BEV. For those new to electric driving, a BEV is more commonly referred to as a pure electric car.

In general, the average EV battery size for a PHEV is 12 kWh, while for pure electric cars, an average battery size is 60 kWh. Moreover, the average emission-free electric range for a plug-in hybrid is between 30 miles to 40 miles, while for BEVs, the average electric range is over 200 miles.

For those keen on leveraging the benefits for electric driving, but not keen to migrate to an all-electric car (BEV), a plug-in hybrid electric car is a sensible step towards lower-emission electric driving. Though much has been discussed and published on electric range, more often in the context of ‘range anxiety‘, it is worth noting, that the majority of car journeys are short. In fact, in the UK, we drive at an average 30 miles a day. An average trip is a mere 12 miles.

Though the average electric range for PHEVs is between 30 miles and 40 miles, a number of leading global automotive manufacturers offer PHEVs that have a quoted WLTP range over 40 miles. Of course, the claimed range and the real-world electric range will differ, with the real-world e-range usually lower than the published WLTP e-range. For those new to electric driving, a number of factors negatively impact the electric range. Some of these include: driving profile, speed, payload, weather conditions, temperature, road surface, tyre size and more!

Even accounting for the above factors impacting the available electric range, plug-in hybrid electric cars offer sufficient range to lower the cost of driving per mile, and reducing local air pollution. Driving on e-mode in a PHEV will be substantially cheaper than using the onboard petrol or diesel engine. Depending on where the plug-in hybrid is charged, and the cost of charging, the average cost per mile will be between 5 pence and 10 pence.

Moreover, tailpipe pollution when driven on the electric mode is zero. Air pollution adversely impacts our health, and road transportation is a significant contributor to the increasing air pollution in the UK. Some of the latest PHEVs have tailpipe emissions below 20g (CO2/km). As an example, the Mercedes-Benz C Class plug-in hybrid has tailpipe emissions as low as 13g (CO2/km).

It is interesting to note, that in our list below of the longest range PHEVs, the average tailpipe emissions is as low as 19.5 (CO2/km). Though significantly lower than a conventional internal combustion engine (ICE) petrol or diesel vehicle, do keep in mind, that a pure electric car has zero-tailpipe emissions! So the sooner we migrate to pure electric cars, the better for us all.

On our list of PHEVs with the longest electric range, we have focussed on plug-in hybrid electric cars that have a manufacturer quoted WLTP range of 50 miles +. Worth highlighting are the Range Rover Sport Plug-In Hybrid and the Range Rover Plug-In Hybrid. Both plug-in hybrid SUVs have a 38.2 kWh onboard EV battery and an electric range of 70-71 miles (WLTP). To put the progress of the development of PHEVs in perspective, the first-generation all-electric Nissan Leaf had a 24 kWh onboard EV battery and a range up to 70 miles!

Land Rover is not the only automotive manufacturer demonstrating progress in the increasing electric range capability of PHEVs. Mercedes-Benz and Volvo also offer a number of plug-in hybrid electric vehicles with an impressive emission-free electric range.

For those keen on buying a plug-in hybrid electric vehicle, we encourage choosing a PHEV with the maximum quoted WLTP range for a given budget. Of course, you will need to assess many other factors too, but in general, the longer the available e-range, the greater the benefits from electric driving. Identifying PHEVs with a range over 40 miles will be a good start!

Driving PHEVs: Top Tips

PHEVs: Top Tips
Charging: We recommend a ‘topping up’ approach to charging a PHEV. Charging an electric car on a regular basis, reduces charging time and also increases the opportunity to leverage the available zero-emission electric range. Moreover, regular charging is better for the health and maintenance of the EV battery. We also encourage the use of a dedicated EV charger for charging a PHEV. We discourage the use of a 3-PIN domestic plug. Using a dedicated EV charger like myenergi zappi, further enhances the benefits of owning a plug-in hybrid!
Electric mode: We strongly encourage using the e-mode as much as possible when driving a plug-in hybrid electric vehicle. The lower the use of the onboard internal combustion engine, the greater is the financial saving and lower the air pollution!
Solar/ Battery Storage:Though, public EV charging infrastructure is debated significantly, most EVs are charged at home. In fact, nearly up to 80% of EV charging is done at home (usually overnight). We encourage the installation of a residential solar and battery storage system. Using clean and renewable energy for charging a PHEV, further reduces the costs of driving an electric car, and the ‘well-to-wheel’ emissions are zero!
Driving profile:The way an EV is driven, will impact the electric range. In general, we recommend adopting a driving profile that incorporates average driving speeds and smooth acceleration. The higher the speed of a PHEV on e-mode, the more is the consumption of electric energy i.e. the lower the available e-range.
