Winter test: From Munich to Berlin in the ADAC test lab

The ADAC has tested the range and long-distance suitability of electric cars in winter. The clear winner is the Mercedes EQS 450+, but models in the mid-price segment are also impressive. A clear demand from the ADAC to manufacturers: to specify the ranges of electric cars not only according to the prescribed WLTP cycle, but also under more demanding conditions, such as in cold weather and in long-distance operation on the motorway.

More models, more range, better charging options – but electromobility still has to contend with prejudices time and again: for example, that an electric car is not suitable for long journeys or winter driving. To get to the bottom of this, the ADAC conducted a comprehensive winter range test to see how electric cars perform in cold temperatures and at motorway speeds.

Twenty-five vehicles were tested in the ADAC electric mobility test laboratory, where a winter journey from Munich to Berlin was simulated (see methodology). The clear winner: the Mercedes-Benz EQS 450+. It even managed the distance of 582 kilometres without a charging break. Particularly impressive: the lowest test consumption of 20.4 kWh/100 km and the rechargeable range of more than 300 km in just 20 minutes. The EQS therefore receives the top rating of ‘very good’. The Porsche Taycan and the Lucid Air also performed strongly, taking second and third place.

Consumers have to pay dearly for the three top positions and thus a long range: All three models are in the luxury segment. However, with the VW ID.7 and the Tesla Model 3 in fourth and fifth place, there are long-distance alternatives starting at entry-level prices of around 59,000 euros and 45,000 euros respectively. Both models prove that electric cars suitable for long journeys are also available in lower price ranges. They offer a good range with low fuel consumption and can also impress on long journeys in cold temperatures.

The MG 4, the Peugeot e-3008 and the Volvo EC40 came in last. The 40 to 50 per cent higher consumption compared to the test winner and longer charging times limit their suitability for long journeys in winter.

The test shows that electric mobility is also suitable for everyday use in winter temperatures and over long distances. Nevertheless, there are major differences that can be decisive for consumers when choosing the right vehicle. As expected, there were differences between the manufacturer’s specifications and the actual range when driving on the motorway at 0 degrees, although some of these differences were significant.

The ADAC is therefore calling on manufacturers to specify the ranges of electric cars not only according to the prescribed WLTP cycle, but also under more demanding conditions, such as in cold weather and in long-distance motorway driving. This is the only way car buyers can realistically assess which vehicle really meets their needs. The development of more affordable vehicles with sufficient range also needs to be driven forward in order to promote electric mobility for cost-sensitive buyers and make e-mobility affordable.
