Every car, whether it has a big V8 engine or an electric motor powering the wheels, is being equipped with fuel saving technologies.

Recall variable-valve timing. Introduced on the Acura NSX, and at one time a revolutionary technology, now practically all cars have some form of VVT. Now more technologies are being introduced as innovations for saving fuel.

In a bid to improve fuel economy without sacrificing performance Volvo will bdegin fitting two new gasoline turbocharged direct-injection (GTDi) engines in two of its cars later this year. Both a turbocharged 3-cylinder and 4-cylinder will be offered for the new S60 and V60 wagon.

The 1.6-liter GTDi T3 makes 148-hp with as much as 177 ft-lbs of torque. As for the T4 powerplant, it will produce 177-hp and 177 ft-lbs, with an overboost function that delivers up to 199 ft-lbs of torque. Both engines will be made entirely from aluminum to minimize weight.

Volvo expects the new engines to cut fuel consumption and emissions by as much as 20 percent.

The new engines will be fitted exclusively to the S60 and V60 models at first and there’s no word on if Volvo plans to offer either in North America. And as unlikely as it is, the T4 engine could see use in the S60 here, or perhaps in the next generation S40.

We expect Volvo to make an announcement of the new powerplants when it officially unveils the new V60 at the Paris Auto Show.
