So far so good, except with the car and trailer separated, two things came to mind. First, without a hitch lock securing it, the trailer was at risk of being stolen; and second, I had arrived on a one-way road used by HGVs and there was no road back to the parking lot.
I asked the cashier at the truck service station what to do. “Go back the way you came,” he said. “If you’re careful, you’ll avoid a truck.”
I took his advice and, carefully negotiating a blind turn out of the truck zone, drove into the parking lot. The Enyaq has a CCS charging port, so I was able to connect to a 120kW Gridserve charger. At this point the battery was showing 19 per cent, but after 30 minutes and a 22.40kWh infusion costing £13.36 it was down to 50 per cent. This restored the car’s range to 129 miles. That was enough, I decided, especially with the Discovery out of sight and unsecured.
I returned to the trailer, hitched up and headed to the campsite, just four miles away, to relax in the well-appointed interior of the trailer.
Later, back at Bailey, I did the math. During the 60 miles of towing the trailer, the Enyaq had returned 2.0 mpkWh. Multiplying that by the usable battery capacity yielded a range of 154 miles when towing, or about 55% of the 277-mile range I could expect to achieve while driving the Enyaq without the trailer.
