Mercedes E-Class hybrid range, MPG, CO2 & charging

The Mercedes E-Class hybrid has a decent electric range and impressive CO2 and MPG figures, on paper at least

MPG CO2 Electric range Wallbox charge time
135-166mpg 41-46g/km 31-34 miles 2hrs (10-100%)

If your daily round-trip commute is less than 30 miles and you can charge up at home or at work, you'll never need to put fuel in the E-Class hybrid unless you're planning a longer journey. Conveniently, Mercedes offers two cables as standard that allow you to plug into a normal three-pin plug at home, or a Type 2 cable gives access to most dedicated car chargers.

The cables are both eight metres long, which is usefully longer than most standard charging cables and will help those who have awkwardly-placed sockets to reach. 

Mercedes E-Class hybrid range, MPG & CO2 emissions

The maximum claimed electric range for the E-Class hybrid differs slightly depending on which version and bodystyle you go for, with the E 300 e petrol saloon managing 31 miles, the E 300 de diesel estate 32 miles and the E 300 de diesel saloon 34 miles.

In all cases, these should be viewed as a maximum figure, with variables such as your driving style, the type of roads travelled and the outside temperature all affecting exactly how long the electric motor can drive the car for.

We found that the E 300 de would do around 20 miles quite easily in varied driving, while 25 miles should be achievable if you spend most of your time around town.

The claimed economy figures are 'ideal maximums', too, and depend on you using that electric range to its fullest extent. If you tackle long-distance motorway trips on a more regular basis, the E 300 de will probably work out more cost-effective in the long run than the E 300 e petrol, given that it costs much the same on purchase and company car costs, and will return over 50mpg quite easily while the diesel engine is running. Meanwhile, the petrol will manage more like 35mpg. 

Charge time

The E-Class hybrid's 13.5kWh battery can be charged from almost empty to full in a little under two hours from a typical home wallbox charger, with a charging speed of 7kW.

Charging from a standard domestic power socket at 3kW will be slower, but still easily accomplished within five hours or so overnight.
