Volvo Looks to Replace 5-Cylinder Lineup with Turbo-4's
It seems like all of the world's automakers these days are beginning to realize the potential of smaller turbocharged engines. Thankfully, this rarely comes at the expense of performance, making them extremely versatile when it comes to sportier models. Volvo has given us yet another example of this with their latest GTDi Engine
GTDi, which stands for Gasoline Turbo Direct Injection, uses the tried and true combination of Direction Injection and Turbocharging to reduce the amount of fuel being consumed without giving up power. The first of this new engine lineup will be a 16 valve 2.0 liter gasoline powerplant. Power ratings come in at 203 horsepower and 221lb/ft at the crank. There is also an overboost function that will offer up an additional 15lb/ft for short bursts. For comparison, the current 2.5 liter engine cranks out 208 horsepower and 235lb/ft.
The GTDi engine will also use a variable timing camshaft, capable of independently adjusting the intake and exhaust valves to offer maximum efficiency. The system will also help to flatten out the torque curve so higher gears can be used for longer periods of time.
The first vehicle in Volvo's lineup to see the new engine will be the S80, followed by the V70 and XC60. Different engines will also be developed on this platform for use in other models.
