The data indicates that the Peugeot 407 3-door Coupe 2.2 SE primarily features a 2.230cc petrol engine, accounting for 100% of the sample. Additionally, almost all vehicles (98.9%) use petrol as their primary fuel, with a small fraction (1.1%) being bi-fuel gas vehicles. This suggests that petrol engines were overwhelmingly prevalent for this model during its production period.
