While the electric car revolution is still in its infancy in South Africa, the growing move to battery electric vehicles (BEV) elsewhere in the world is showing there are still many obstacles to overcome – the latest highlighted in the recent WhatCar ‘Tow Car Awards’ where electric vehicles fell short.
With more than 98 000 registered caravans in South Africa, this form of holidaying is still extremely popular and needs to be taken into consideration in every decision relating to the move to BEV.
As part of the judging process for the awards, eight of the latest electric cars were range tested with and without a caravan.
The best performer managed 180 km while towing a caravan weighted to 85% of the car’s kerb weight (the maximum recommended), and the worst just 125 km. Meanwhile, the average drop compared with the range without a caravan on the same test route and in the same weather conditions was 54,6%.
By comparison, the fuel economy in a petrol or diesel car typically drops by around a third when towing, so it will be necessary to stop more often with an electric car. Plus, topping up is likely to be much more complicated.
None of the motorway services run by the three main operators in the UK currently allow caravanners to charge without first unhitching. And due to one-way systems, some make it impossible to get back from the chargers to the towing parking area.
What Car? editor Steve Huntingford says: “Electric car ranges have improved massively over the last decade, but towing is always going to reduce how far you can go on a charge, so it’s crucial the infrastructure is in place to support those who use their cars to pull a caravan or trailer. At the moment their needs feel like an afterthought, even though the ban on the sale of new petrol and diesel cars in the UK is just eight years away.”
For now, a model with a combustion engine remains the only suitable option for many caravanners, with the Audi Q5 40 TDI quattro diesel named the best car for towing in 2022.
Huntingford explained: “Stability has to be the number one priority when towing, and the Q5 is as solid and secure as they come. However, it also offers a fantastic blend of performance and practicality, and is cleaner and more efficient than traditional diesel models, thanks to mild-hybrid electric assistance.”
Before deciding on the overall winner in 2022, the judges handed out awards to cars in five different towing weight classes, ranging from up to 1 400 kg to more than 1 900 kg. They also named the best tow car for practicality and the best electric, plug-in hybrid and estate cars for towing.
In addition to taking the top prize, Audi won the 1 700-1 899 kg weight category with the Q5.
Two other manufacturers also took home a brace of awards: Kia won the 1 900kg+ category with the Sorento 2.2 CRDi and best electric tow car with the EV6 77,4 kWh AWD, while Skoda won the up to 1 400 kg and 1 550-1 699 kg weight categories with the Scala 1.0 TSI and Karoq 2.0 TDI Evo 150 4×4 DSG respectively.
Testing was undertaken by matching eligible cars to caravans weighted to 85% of the car’s kerb weight or its legal towing limit, depending on which was lower. They were then ballasted to simulate driving with passengers and luggage.
