The guide preserves the provider’s published tunnel geometry, testing descriptions, contact route and reseller booking wording. Its VCA statement remains provider-published historical wording about an early-2023 WLTP coastdown certification; this guide does not assert a current certificate, complete WLTP scope, acceptance, booking, price, capacity, availability, support or lead time.
