English: Volvo 340 1.7 engine. An engine from a Volvo 340. It's a Renault engine, and the most rare of the Volvo 300-series. It's a very smooth and powerful (80hp, 115Nm) engine with also a nice fuel-economy. This was the F2N when installed by Renault, but in Volvos it was called B172 instead. Unfortunately, it didn't succeed because of some some reliability problems with it's carburetor.
