All the "Volvo" 4 cylinder diesels are Renault based starting from the D16 in the 300 series to the latest D4194T4 in the last S/V40 , they are evolved from the D16 unit ... which in itself was a conversion of the B172K Renault based petrol engine which started life in the 300 in 1986 .
The Renault based Engines have always performed well in a volvo and are fairly trouble-free and long-lasting ..
The Renault connection began when Volvo bought DAF in the 1970's , the first car volvo brought out was a modified DAF 66 which used Renault engines( Volvo 66 ) they continued that relationship all the way through until 2004 . The first B14 in the 300 was modified by volvo , it had better quality pistons , crankshaft and valves than Renault used . Later these mods found themselves in Renaults .
Renaults in turn use the Volvo B5254 in the Safran model and the B4204 from the V40 in the megane or Laguna .
