What the DF361 Is

The DF361 is a four-cylinder diesel engine developed by Renault in the mid-to-late 20th century for light commercial vehicles and industrial applications. It was designed to prioritize durability and fuel economy over outright power, making it well suited to high-mileage use and heavy-duty daily work.

2. Surprisingly Efficient

Drivers consistently report that the DF361 returns better real-world MPG than the lower-powered 100hp version. Why? Because you don't have to floor the accelerator to keep up with traffic. The engine sits comfortably at 70mph with low revs, saving you diesel money every single mile.
