Hyundai Bayon CNG Expected Engine and Gearbox

The Bayon CNG is expected to use the existing 1.5-litre, four-cylinder naturally aspirated petrol engine. In the petrol version, it produces 115 PS and 143.8 Nm, but the CNG version is likely to have lower output, along with any claimed mileage figure for it.
