The short answer: there is no current diesel Honda Accord available in the major markets. Today’s Accord lineup worldwide relies on petrol and hybrid powertrains, and in the United States a diesel option has never been offered. If you’re looking at older models, diesel versions exist in certain European markets and their mileage varied by generation and testing method.
Current availability
Here is a quick snapshot of current availability by market to set expectations before we look at historical numbers.
- United States and Canada: no diesel option for the Honda Accord.
- Europe: diesel engines were phased out; the current Accord is petrol and hybrid-only.
- Other markets: diesel availability varies, but recent generations primarily use petrol or hybrid powertrains.
In short, if you are shopping for a new Honda Accord today, expect petrol or hybrid powertrains rather than diesel.
Historical diesel variants and their economy
The following outlines diesel engines that have appeared in the Accord over the years and the typical mileage those engines delivered in common European test cycles. Figures vary by year, transmission, and driving conditions.
- 2.2-liter i-CTDi (approximately 2003–2007): typically reported in the mid-40s to mid-50s miles per gallon (UK combined), with better figures on highway driving and with manual transmissions.
- 2.2-liter i-DTEC or related diesel variants (appeared in some markets in the 2010s): commonly offered in the 50–60+ mpg UK range on the combined cycle, depending on the exact model and test standard.
Note: Diesel fuel economy figures for older Accords varied widely by market, test cycle (NEDC vs WLTP), transmission, and wheel options. For precise numbers, consult the brochure for the exact year and market you are considering.
Summary
Key takeaways: The Honda Accord currently does not offer a diesel engine in major markets. If you are researching an older model, diesel Accords historically delivered roughly 45–60 mpg UK combined, depending on generation and test method. Always verify official figures for the specific year, market, and transmission you are interested in.
