Small car road tax UK — small vehicles with low CO2 emissions offer the best tax efficiency for non-EV buyers. Here are the most road tax-efficient small cars available in 2026.
Why Small Cars Have Lower Road Tax
Road tax is calculated by CO2 emissions, not vehicle size. However, smaller cars tend to have smaller, more efficient engines that produce lower CO2 figures. A city car with a 1.0-litre petrol engine may emit 110-120g/km, placing it in a lower VED band than a large SUV with a 2.0-litre diesel engine emitting 180g/km.

- Ford Fiesta 1.0 EcoBoost (92g/km): £130 first year, £190/year standard — excellent low-emission small car
- Volkswagen Polo 1.0 TSI (106g/km): £130 first year, £190/year standard
- Renault Clio E-Tech Hybrid (104g/km): £130 first year, £50/year standard (hybrid)
- Toyota Yaris Hybrid (92g/km): £130 first year, £50/year standard (full hybrid)
- Peugeot e-208 Electric (0g/km): £0 first year, £10/year standard

The electric Peugeot e-208 costs £0 first-year road tax versus £130 for the petrol Fiesta. Over 5 years (years 2-6), the e-208 costs £10/year versus £190/year for the Fiesta. Total 5-year road tax: e-208 = £50, Fiesta = £1,080. The EV saves £1,030 over 5 years in road tax alone.
