What Engine Does My Car Have? Engine Specification Check

Knowing your engine size, type, and power output helps you understand your car's performance, insurance group, tax band, and maintenance costs. Here is how to find and verify engine specifications.

Where to Find Engine Information

  • V5C logbook — shows engine size (in cc) and fuel type clearly in the vehicle details section
  • DVLA Vehicle Enquiry — vehicleenquiry.service.gov.uk shows engine size and fuel type from any registration
  • Engine block — codes are physically stamped on the engine itself, near the top or side
  • Manufacturer handbook — lists full engine specifications for all variants of the model
  • Vehicle history report — VEHIXA displays engine specs as recorded by DVLA

Common Engine Types

Petrol

Most common in smaller and family cars. Responsive, lower purchase price to service. Higher emissions than diesel for long distances.

Diesel

Better fuel economy, especially at motorway speeds. More expensive to service. Particle filter (DPF) issues if used mainly for short trips.

Hybrid

Petrol or diesel combined with an electric motor. Lower emissions and fuel consumption. Battery replacement cost is a long-term consideration.

Electric (EV)

Battery-powered only. Zero tailpipe emissions. Range and charging infrastructure are the key practical considerations.

Engine Size (Displacement)

Engine size is measured in litres (L) or cubic centimetres (cc). A 1.6L engine equals 1,600cc. Larger engines are generally more powerful but consume more fuel and attract higher insurance premiums.

Modern turbocharged engines deliver significant power from small displacements — a 1.0T may produce as much power as an older naturally-aspirated 1.6L. Focus on output figures (BHP/PS/kW) alongside displacement.

Checking for Engine Swaps

If buying a modified or performance car, verify the engine is the one listed on the V5C. Compare the engine code on the block against DVLA records. Unreported engine swaps are not recorded with DVLA and can invalidate insurance.

Check any registration on VEHIXA to see engine size, fuel type, and technical specifications from DVLA records.
