Dubbed 2.5FT, the boosted engine now develops 231 horsepower and 340 Nm of torque. It will become available in the Volvo S80 and Volvo V70 starting June, and will come with a choice of either a manual or an automatic transmission.
The engine has a combined cycle while running-on-petrol fuel consumption rate of 8.8l/100 km for the V70 and 8.6l/100 km for the S80, both fitted with the manual transmission. For the automatic versions, fuel consumption stands at 9.7 l/100 km for the V70 and 9.6 l/100 km for the S80. While running on E85, fuel consumption increases by about 30 percent depending on driving style, ambient temperature and variations in fuel specification.
The work put behind this enhancements is not as difficult as you might expect. The only thing Volvo did to get the extra power was to adopt new software which raises the turbocharger's boost pressure.
As for the fuel consumption gains, tampering with engine revs was all it took to get the 5-6 percent drop. The new revs were obtained by making the fifth gear in the manual transmission have the same ratio as the previous sixth gear, while sixth is now a pure overdrive ratio.
"This technical advance shows that we can give buyers of our larger cars an attractive combination of enhanced driving pleasure and better environmental properties. Few, if any, of our competitors can match our ever-wider and more efficient green-car model range," Magnus Jonsson, Volvo product development vice president said.
