Engine H4B-CNG – Be Careful 2,950–7,150 $

Renault's 0.9-litre three-cylinder turbo engine running on factory-fitted CNG. Turbocharger and ignition coils are known wear items, as with the petrol version. CNG cylinder inspection required every 4 years; ensure adequate valve lubrication when running on gas.

Fun Factor? Not Really

CNG holds the little one back

The 0.9 TCe with CNG loses noticeably in performance. Add in the limited CNG station network — this one's only for committed gas drivers.
