Where the Infiniti 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.
