Volvo’s V70 and S80 models will be available with two new flex-fuel engines from the end of the year, making its entire lineup now flex-fuel ready. The V70 and S80 get either a new 2.0L four cylinder or a turbocharged 2.5L five cylinder.

The existing petrol engines have been modified for E85, with the 2.0L unit producing 145hp (107kW) and 185Nm of torque, and the 2.5L unit developing 200hp (147kW). The flex-fuel variants of the Volvo S40, V50 and C30 will continue with the four-cylinder 1.8L naturally aspirated engine, which produces 125hp (92 kW) and 165Nm of torque.

To make the conventional engines flex-fuel ready, engineers needed to adapt the fuel hoses, valves and gaskets to handle ethanol's more corrosive properties, add reinforced injection valves and mod the engine’s electronic management system.
