Fuel-efficient diesel cars

Diesels still appeal when the trip computer spends a lot of time at motorway speeds. Diesel–electric hybrids listed here behave similarly: the combined figure rewards steady cruising. Urban start–stop grinding can narrow—or erase—the advantage versus a modern petrol or hybrid.

Like the other tabs, we surface one row per model using its lowest combined consumption entry. That is a brochure-normalised snapshot, not a forecast of your fuel card totals.

When two SUVs or estates look tied on fuel, layering luggage needs via comparison usually breaks the stalemate faster than chasing another decimal place on paper.
