Smart EQ forfour vs Smart Forfour 0.9 Turbo: which costs less to run?

How much cheaper is the Smart EQ forfour to run? In United States, its estimated energy cost is about $5.79 per 100 mi, while the Smart Forfour 0.9 Turbo costs around $8.3. The difference is roughly $343 per year, or $1,716 over five years at the selected mileage.

These are model-based estimates rather than measurements from one identical test: the EV uses the selected road and climate profile, and the Smart Forfour 0.9 Turbo uses an official-cycle fuel figure with a correction factor. Average local prices are $0.17/kWh for home electricity and $3.26/gal for fuel. For a 186 mi trip, the estimates are $24.7 in the EV and $15.48 in the Smart Forfour 0.9 Turbo.

Compare charging and fuel costs for this model

We have created dedicated comparison pages for this EV and selected petrol, diesel and hybrid rivals. The calculations use the EV's selected road-and-climate consumption estimate, an adjusted fuel-consumption estimate for the rival, and electricity and fuel prices for the selected market. Each page opens the calculator with that model pair preselected:

How this calculator works

EV consumption and range are calculated using model-specific estimates for different driving and climate conditions. The official WLTP range is shown for reference where available, but the calculations are based on the selected scenario rather than directly on the WLTP value.

The home-charging calculation includes an estimated 10% charging loss. No additional loss factor is currently applied to public DC charging. Electricity and fuel prices are market averages with a visible update date, and all prices, charging shares and mileage values can be adjusted with the sliders.

Fuel consumption for petrol, diesel and hybrid rivals is calculated from their official WLTP, EPA, NEDC or manufacturer figures using correction factors for the relevant test cycle. You can also replace the estimated consumption and fuel price with your own values.

All results are estimates. Weather, driving style, load, charging losses and local tariffs can change the actual result. The data behind this calculator is maintained and reviewed by the Elbil RADAR editorial team. If you spot an error, use the contact page and we will review it.
