Hyundai Kona Blue Drive.
What to Check Before Buying.

The Hyundai Kona Blue Drive suits eco-conscious buyers seeking lower running costs without switching to electric or hybrid power. This diesel variant combines the 1.6 CRDi engine with aerodynamic enhancements and low rolling resistance tyres to achieve impressive fuel economy, often exceeding 60mpg in real-world driving. The Blue Drive benefits from reduced road tax thanks to lower CO2 emissions, making it an economical choice for high-mileage drivers and commuters. However, the diesel particulate filter can be problematic if the car has been used primarily for short urban journeys, so check the service history for DPF regeneration issues or warning lights. When inspecting a used Kona Blue Drive, verify that the stop-start system functions correctly and examine the tyres to ensure they are the correct eco-spec fitment, as standard replacements will increase fuel consumption. Request evidence of regular oil changes using the correct low-SAPS specification oil, which is essential for protecting the diesel emissions system. The Blue Drive represents excellent value if it has been maintained properly and driven appropriately for a diesel engine.
