How much CO2 does a Ford C-Max produce?

A quick answer: the CO2 output depends on the model and testing cycle. Plug-in hybrid C-Max Energi variants typically emit about 40–50 g/km under WLTP, while conventional petrol and diesel versions generally produce higher, around 100–150 g/km depending on engine and configuration.


In more detail, CO2 figures are influenced by the powertrain, year of manufacture, weight, and the emissions standard used for testing (NEDC, WLTP, or EPA). The plug-in hybrid can run on electricity to lower tailpipe emissions, whereas gasoline and diesel variants burn fuel that translates to higher CO2 per kilometer on average. Below are the typical ranges you’ll encounter for common C-Max configurations.


CO2 emissions by variant


The following ranges reflect typical values reported in modern testing cycles. Exact numbers for a specific car can vary by trim, gearbox, and market.


Plug-in hybrid: Ford C-Max Energi


These figures show how the plug-in hybrid variant typically compares, noting that counting electricity use affects the overall rating.



  • CO2 (WLTP, plug-in Energi): approximately 40–50 g/km

  • CO2 (NEDC, older testing): around the mid-40s g/km

  • Notes: The Energi can drive on electric power for a portion of trips, which lowers the average CO2 per kilometer on test cycles that credit electric driving.


Concluding for plug-in hybrids: Their CO2 footprint is notably lower than conventional variants, but the exact value depends on how the vehicle is charged and driven during the test cycle.


Gasoline C-Max variants


Gasoline-powered versions vary by engine size and transmission. The CO2 figures tend to be higher than the plug-in hybrid because fuel is burned for propulsion in all cycles.



  • Gasoline C-Max (1.0–1.6L engines): typically around 120–150 g/km (WLTP), depending on the exact engine and gearbox


Concluding for petrol models: Expect higher CO2 numbers than the Energi plug-in, with the range largely governed by engine displacement and efficiency.


Diesel C-Max variants


Diesel-powered versions generally offer lower CO2 emissions than their petrol counterparts due to higher fuel efficiency, though results vary by engine tuning and year.



  • Diesel C-Max (1.6 TDCi and similar): typically around 100–120 g/km (WLTP), depending on the configuration


Concluding for diesel models: Diesel variants often deliver the lowest CO2 among non-plug-in C-Max configurations, but always check the exact certificate for the specific car.


Additional considerations


Testing standards matter. WLTP and NEDC numbers can differ by a notable margin, and real-world emissions depend on your driving style, trip length, charging habits (for plug-in hybrids), and the electricity mix used when charging. For used-car buyers, the vehicle’s CO2 certificate on the V5C/logbook or the manufacturer’s spec sheet will give the precise figure for that exact model and year.


Summary


The Ford C-Max’s CO2 emissions vary widely by powertrain and test cycle. If you’re aiming for the lowest CO2 output, the C-Max Energi plug-in hybrid is the clear leader among C-Max variants, followed by diesel versions. Petrol variants generally emit more CO2. Always check the specific CO2 rating on the vehicle’s official certificate to know the exact figure for a given car.

What does C-Max stand for?


Cmax is the maximum (or peak) serum concentration that a drug achieves in a specified compartment or test area of the body after the drug has been administered and before the administration of a second dose. It is a standard measurement in pharmacokinetics.



Why did Ford discontinue C-Max?


Ford is dropping the Grand C-Max, shown, because of a sharp drop in demand as customers switch to SUVs and crossovers. Ford confirmed it will end production of its C-Max minivan at its factory in Saarlouis, Germany, but said the plant will stay open with further investment in the Focus car that is also built there.



How much CO2 does a 1.0 EcoBoost engine produce?


At the end of 2013, Ford announced Ford has announced an ultra-efficient version of the Focus 1.0-litre EcoBoost that was the first petrol-powered family car in Europe to offer 99 g/km CO2 emissions.



What is the CO2 emissions for the Ford C-MAX?


The average CO₂ emissions for a FORD C-MAX is 137.8 g/km. Explore CO₂ output data for the FORD C-MAX. Below you'll find g/km figures, DVLA CO₂ bands, Euro emission class, fuel type, engine size, and indicative 12-month VED.
