Choosing a family car involves balancing practicality, safety and running costs — and road tax is an often-overlooked element of the total cost of ownership. Here is how to pick a family car with low VED costs in mind.

CO2 and Family Car Size

Family cars tend to be larger — SUVs, MPVs and estate cars — which typically produce higher CO2 emissions than small hatchbacks. A large SUV with a 2.0-litre turbo petrol engine may emit 180g/km or more, placing it in the £540 to £580 first-year VED band. A comparable petrol MPV may be similar. Choosing a model with a lower CO2 figure — even within the same body style — can save hundreds in first-year VED.

Zero-Emission Family EVs

Electric family cars such as the Tesla Model Y, Kia EV9 and Volvo EX90 offer the lowest possible VED: £0 first year and £10 per year from year two. While the upfront purchase price is higher, road tax savings accumulate significantly over ownership. For families keeping a car for five years, the £900+ saving in road tax versus a petrol equivalent (£190 x 5) is meaningful. Use the car tax calculator at Cartax.online to compare VED across specific family car models.

Taxis and Private Hire Vehicle Considerations

If you use your family car for private hire or taxi work, different rules apply. Private hire vehicles are classified separately for VED purposes and may qualify for reduced rates depending on their use. If a vehicle is used primarily as a licensed taxi, it may be exempt from standard car VED. Check with DVLA and your local licensing authority for specific rules. Incorrect classification can result in overpayment.

Premium Rate Warning for Large Family Cars

Many popular large family SUVs and premium MPVs have list prices above £40,000 — including the BMW X5, Audi Q7, Mercedes GLE and Volvo XC90 in higher specifications. These attract the £410 annual premium supplement on top of the standard £190 rate: £600 per year from year two. This adds £2,050 over five years. Factor the premium rate into the total cost when comparing higher-specification variants of otherwise sensible family cars.

MPV vs SUV: Which Has Lower VED?

Both MPVs and SUVs span a wide range of CO2 emissions depending on engine and size. In general, purpose-built MPV platforms tend to have slightly lower CO2 than large SUV platforms because they prioritise interior space over styling and off-road capability. However, the difference is marginal — always check the specific model's WLTP CO2 figure rather than generalising by body type. A low-CO2 7-seat PHEV like the Volvo XC90 Recharge may have similar or lower VED than a higher-CO2 petrol MPV.
