The data indicates that nearly all vehicles in this model are equipped with a 1.8-liter petrol engine, with a 100% prevalence of the 1796cc engine capacity. Additionally, the majority (99.5%) of these vehicles use petrol as their primary fuel, with only a small fraction (0.5%) operating on gas bi-fuel systems. This suggests a very uniform specification profile for the Mercedes-Benz CLC (2008-12) 180K 3DR Coupe 1.8, predominantly featuring petrol engines of 1.8 liters.
