How much does a Smart #1 cost to run per mile in the UK?
At a standard UK home electricity rate of 28p/kWh and a real-world efficiency of 3.5 miles/kWh, the Smart #1 costs approximately 8.0p per mile when charging at home. On a dedicated overnight EV tariff (around 7p/kWh) this falls to just 2.0p per mile. Relying entirely on public rapid charging at 60p/kWh raises the cost to 17.1p per mile.
Is the Smart #1 cheaper to run than the Mini Hatch?
Yes, for most UK drivers who can charge at home. The Mini Hatch costs approximately 16.4p per mile in petrol at current UK prices. At home on a standard tariff, the Smart #1 costs 8.0p per mile — a saving of 8.4p per mile. At 10,000 miles per year with 80% home charging, the Smart #1 saves around £653 per year in fuel costs.
How long to break even switching from a Mini Hatch to a Smart #1?
Based on an estimated price premium of £12,000 for the Smart #1 over the Mini Hatch, and annual fuel savings of approximately £653 at 10,000 miles per year (80% home charging), the break-even point is around 18.4 years. Drivers covering more miles will reach break-even sooner — at 15,000 miles per year the saving is proportionally larger.
What if I can't charge the Smart #1 at home?
Without home charging, the economics change significantly. Relying on public rapid charging at 60p/kWh puts the Smart #1 at 17.1p per mile — higher than the Mini Hatch at 16.4p per mile. EV running cost savings are almost entirely dependent on home charging access. Drivers without off-street parking should factor this in carefully.
