Stage 1 remapping in Winchester
Fewer than a third of working residents in the Winchester built-up area drove to work in the 2021 Census: 30.9%, against 45.1% across England and Wales and 40% in the Winchester council area. Long journeys still feature, though, with 6.7% travelling 30 km or more, above the England and Wales figure of 4.4%. Census day fell in a lockdown, so neither number describes commuting today. Where a car does make longer runs, that is where Stage 1 remapping is felt most. Fuel, boost and timing are adjusted in software within the engine's limits, and a diesel gains torque in the mid-range, where overtaking happens.

Across the Winchester council area there were 85 privately kept vans per 1,000 privately kept cars at the end of June 2026, above England's 81. In 2025 MOT tests across SO postcodes, the Ford Transit and Volkswagen Transporter were the most tested diesel vans. Joining the M3 or the A34 with a loaded van is where extra low-rev torque helps, within the limits of the gearbox and clutch.
