Where the Lexus figures come from

Rebuilt from the archived Honest John Real MPG dataset after the site closed in 2026, with the official NEDC and WLTP figures kept alongside the owner-reported averages, plus new submissions from CarAdCheck readers. Each model page links to the archived page it was built from.

CarAdCheck is not affiliated with Honest John or Volkswagen Financial Services. How we rebuilt Real MPG.
