Electric vs Hybrid: what fits your commute?

By Julian Thorne, Fleet Manager·January 14, 2025·9 min read

Choosing between a battery electric vehicle (BEV) and a plug-in hybrid (PHEV) isn't just about being green. For most of our members working at Thames Valley Park or Green Park, it comes down to how often they can actually plug the car in. We looked at 8 months of data from 19 drivers to see what works in the real world around Reading.

The charging map for RG1 and RG2

If you live in a flat near Station Road or over in the Oracle area, you probably don't have a driveway. This is the biggest hurdle for going full electric. We found that 11 of our members rely entirely on public chargers. There are currently 47 reliable fast-charging points within a 3-mile radius of the Reading town centre, but they are often busy between 17:30 and 19:00. If you can't charge at home, you might spend 3.5 hours a week sitting in a car park waiting for a top-up.

Hybrid drivers in our group tend to use the petrol engine for 64% of their total mileage. This happens because they forget to charge or find the public stations occupied. However, those who work at offices with dedicated charging bays, like those in Winnersh Triangle, manage to do their entire 12-mile commute on battery power alone. It saves them about £38 per week compared to a standard petrol car, but only if they remain disciplined about plugging in every single morning.

If you don't have a driveway in Reading, a hybrid usually prevents the 19:00 charging scramble at the local supermarket.

Cold weather and the M4 corridor

Last February, we recorded a 23% drop in range for our fully electric SUVs. When the temperature hits 2 degrees Celsius, the heaters and battery management systems work much harder. One driver commuting from Reading to Slough saw his range drop from 240 miles to roughly 184 miles on a single charge. This is a common occurrence that brochures often gloss over. It doesn't mean the car is broken, but it does mean you have to plan your Friday trips more carefully.

Hybrids handle the cold better because the petrol engine generates its own heat. For a developer working late hours who just wants to get home without checking an app, the hybrid offers a safety net. During our tests on the M4, the BMW 330e maintained its efficiency much better than the pure electric alternatives when the frost hit. You still get the quiet drive in town, but the petrol engine takes the load once you hit 70mph on the motorway.

Maintenance and the monthly bill

At Off Hours Coding, one monthly bill covers your insurance, tax, and servicing. With an electric car, there are fewer moving parts, so we see 31% fewer service visits compared to petrol models. However, tyres on EVs wear out about 14% faster because the cars are heavier due to the battery packs. We replace tyres on our Tesla models every 17,000 miles, whereas our hybrid Volvo V60s usually make it to 22,000 miles before the tread gets too low.

Hybrids are more complex because they have two systems. This means they spend slightly more time in our workshop for routine checks. We noticed that our 7 active hybrid vehicles required 2 extra sensor calibrations over the last 11 months compared to the pure electric fleet. For the driver, this doesn't change the cost since it is all included in the subscription, but it might mean a car swap is needed more often to keep the fleet in top shape.

Which one should you pick?

The data suggests that if you drive more than 40 miles a day and cannot charge at your house, a hybrid is the logical choice for now. It stops the 'range anxiety' that 5 of our newer members reported during their first month. If you have a dedicated charger at your home in Caversham or Tilehurst, go fully electric. The torque is better for short bursts in traffic, and you will never have to visit a petrol station again.

Honestly, we don't mind which one you choose because you can swap the car anyway. One of our members, a senior dev named Mark, spent 3 months in a Tesla before deciding he hated searching for chargers. He swapped to a hybrid for the winter and will likely go back to electric in the summer. Drive what fits your calendar and your current living situation. That is why we keep the fleet flexible.

We noticed that 23% of our members swap from electric to hybrid after their first cold winter month.
