Honda Accord 2.2 diesel: what mpg you can expect

The Honda Accord 2.2‑litre diesel typically returns about 50–53 mpg (UK) on official combined tests for manual models, equivalent to roughly 41–44 mpg (US) or 5.3–5.7 L/100 km; real-world averages tend to be a bit lower, around 43–48 mpg (UK), depending on generation, body style, and driving mix. Below is a breakdown by model era and factors that influence the result.

What “2.2 diesel” means on the Accord

Honda sold two main 2.2‑litre turbo-diesels in the European/UK Accord: the earlier 2.2 i‑CTDi (around 2003–2008) and the later 2.2 i‑DTEC (around 2008–2015). Official consumption figures were certified under NEDC tests for most of this period, which are typically more optimistic than real‑world results. Body style (saloon/sedan vs tourer/estate) and transmission (mostly 6‑speed manual, some later automatics) also affect mpg.

Official combined fuel economy by generation

The following list summarises commonly quoted official combined-cycle figures (manufacturer and period road-test data) for the Accord 2.2 diesel, shown as ranges to cover trims, wheels, and body styles. Conversions are provided to US mpg and L/100 km for clarity.

• 2003–2008 Accord 2.2 i‑CTDi (manual):
  49–52 mpg (UK) ≈ 41–43 mpg (US) ≈ 5.4–5.8 L/100 km; tourer/estate typically 1–3 mpg (UK) lower than saloon.
• 2008–2015 Accord 2.2 i‑DTEC (manual):
  50–53 mpg (UK) ≈ 41–44 mpg (US) ≈ 5.3–5.6 L/100 km; incremental improvements after the 2011 refresh.
• 2009–2015 Accord 2.2 i‑DTEC (automatic, selected markets):
  about 45–50 mpg (UK) ≈ 37–42 mpg (US) ≈ 5.6–6.3 L/100 km; autos trend lower than manuals.

These figures reflect official combined-cycle testing for the period. Individual trims, wheel sizes, and options can nudge results up or down by a couple of mpg.

Real-world economy: what owners typically see

In everyday driving, most owners report slightly lower consumption than official lab tests. Mixed-use driving, short trips, and urban congestion can reduce mpg; steady motorway cruising can improve it. The bullet points below reflect typical owner-reported ranges.

• Everyday mixed driving: roughly 43–48 mpg (UK) ≈ 36–40 mpg (US) ≈ 5.9–6.6 L/100 km.
• Motorway/dual carriageway cruising at moderate speeds: low‑50s mpg (UK) are common; some see mid‑50s on long, gentle runs.
• Urban/short-trip use, cold weather, or DPF regens: mid‑30s to low‑40s mpg (UK) ≈ high‑20s to mid‑30s mpg (US).

Driving style, trip length, tyre choice/pressures, servicing, and ambient temperature are the biggest variables. A healthy diesel reaching full operating temperature on longer journeys will do markedly better than one used mainly for short urban hops.

Context on test cycles

Most Honda Accord 2.2 diesels were certified under the older NEDC test, which tends to overstate mpg versus modern WLTP methods. If you’re comparing to newer cars rated under WLTP, expect the older Accord’s official NEDC numbers to sit a few mpg higher than you’d likely achieve day to day.

Bottom line

Expect around 50–53 mpg (UK) officially for a manual Honda Accord 2.2 diesel (about 41–44 mpg US), with real-world averages more often in the 43–48 mpg (UK) band depending on conditions. Automatics and tourers generally run a little thirstier than manual saloons.

Summary

The Honda Accord 2.2 diesel is a frugal motorway cruiser by legacy standards: officially about 50–53 mpg (UK) for manuals, 45–50 mpg (UK) for automatics; real-world use typically yields 43–48 mpg (UK). Precise results vary with model year (i‑CTDi vs i‑DTEC), body style, transmission, and driving pattern.

How many miles per gallon does a Honda Accord diesel get?

Fuel consumption levels have also been improved by reducing internal frictional losses, with the diesel now recording 53.3mpg (saloon), making it well suited to the mile-munching regime of many corporate cars.

What is the life expectancy of a Honda CRV 2.2 diesel?

Thanks to Honda’s commitment to quality engineering and performance, a well-maintained CR-V can last between 250,000 and 300,000 miles.
