Stage 1 remapping in Swansea
Vans matter more in Swansea than anywhere else in our list of 104 largest towns. At the end of June 2026 the Swansea council area had 12,814 privately kept vans, 105 for every 1,000 private cars, the highest ratio of the 104, and 96.6% of them were diesel. So any honest look at Stage 1 remapping here starts with vans. With weight on board, a diesel van gains most in the mid-range: it pulls away more easily, holds speed on a gradient and needs fewer gear changes when towing. Clutch and gearbox limits still apply, and a sensible remap respects them.

In 2025 MOT tests across SA postcodes, 48% of cars and small vans tested were diesel; the Ford Transit and Volkswagen Transporter led the vans and the Volkswagen Golf the cars. From the roads of the Gower to the M4, a diesel with good mid-range pull is easier work.
