In order to make the most of the BMW 330e’s plug-in hybrid (PHEV) powertrain, you should make sure that it’s always fully charged up before you set off. Like all PHEVs, the 330e works best if you tend to do short and medium-length trips where you can rely on the electric motor to do most of the work, as for longer trips a diesel is more efficient.

BMW 330e range, MPG & CO2 emissions

According to BMW’s official figures, the 330e emits between 31 and 36g/km of CO2 and its electric range is up to 37 miles, depending on the exact specification you choose. That’s an improvement over the pre-2018 version of the car, which could do 25 miles, but we still wouldn’t expect to see 37 miles in the real world without concerted effort – about 30 miles would be safe to bet on from a full charge.

Motorway miles and cold weather, as with all electric models, will reduce your range the most, so if you stick to local roads with low speed limits, you could probably get 35 miles out of the battery on a good day. That should be plenty for most people’s commutes.

In our experience, the 330e returns around 40-45mpg fuel economy in varied use (including some motorway mileage) when the petrol engine is running. That’s better than a Volvo S60 Recharge can manage on the same sort of trips, and considering it’s a petrol-powered saloon, over 40mpg is pretty good in our book. 

However, the equivalent BMW 320d diesel will manage over 50mpg on the same trips, so if you regularly cover big motorway miles, do bear in mind that a diesel will be more economical. It's worth noting that the plug-in hybrid Mercedes C-Class is available with either a petrol or diesel engine, with the latter potentially being more economical, more of the time, than the petrol-electric 3 Series.

Charge time

The BMW 330e's battery takes around five-and-a-half hours to charge fully from a normal three-pin household electricity socket. It’s better to use a home wallbox charger, which will top up the battery in about three and a half hours. Using public charging stations to top up while out and about isn't really worth it, as the BMW's on-board hardware can't take advantage of their higher charging speeds.
