This is how economical the new Mercedes E-class PHEV is with an empty battery -

Does fuel consumption increase as soon as the battery of the Mercedes E-class 300e runs out? That's not so bad. We test the consumption at 100 km/h with an empty battery pack.

It sounds great: the Mercedes E 300e officially consumes 0.6 l/100 km. That's 1 in 166! Now you may think that those numbers make no sense, but the plug-in hybrid E-class can actually drive 100 kilometers on 0.6 liters of petrol. In fact, if the large 25.4 kWh battery is completely full and you drive economically, you can travel 100 kilometers completely emission-free.


Not yet ready for the switch to electric driving?

With Private Lease you can get into the iconic Fiat 500 Hybrid from just €279 per month.

This is how we test fuel consumption

We are curious about the second hundred kilometers of your ride, when the battery is empty and the two-liter petrol engine has to do all the work. Because let's be honest: the comfort of the new E-class is designed to drive hundreds of kilometers in a row.

To test consumption, we subject the Mercedes E 300e to our test range test for electric cars. A highway ride of 100 kilometers that takes into account height differences and tail and tail winds. The weather is autumnal: drizzle and 11.5 degrees. Naturally, we start the test drive with an empty battery. We are driving at a speed of 100 km/h.

Left: 94 km on a single battery charge (drive at a high speed of 100 km/h). Right: petrol consumption with empty battery (entire trip 100 km/h).

Mercedes E-class E 300e: consumption at 100 km/h

With an empty battery pack, we measure an average fuel consumption of 5.8 l/100 km or 1 in 17.2 for the Mercedes E 300e. That's how little gasoline it costs to drive relaxed on the highway during the day with the rest of the traffic. The capacity of the fuel tank is 50 liters, so after driving the battery empty (94 km, see photo above) you can still cover more than 850 kilometers on petrol.

Special mention for the hybrid system: the battery may be 'empty', but the E-class continues to function as a normal hybrid car. Which means that it recovers power when coasting and covering short electrical distances. In this way he smuggles in 11 free kilometers. Free because the required power does not come from a charging station, but is collected along the way.


The Mercedes E 300e Limousine weighs 2210 kilos. With a full battery, the 129 hp and 440 Nm strong electric motor takes it about 90 kilometers. Then the 204 hp and 320 Nm strong four-cylinder petrol engine takes over the drive and shows a practical consumption of 5.8 l/100 km (1 in 17.2) at 100 km/h. Considering the size and weight of the car, we think that is a decent score.
