Hot New Volvo S60 Concept Car to be Shown at Detroit 2009
December 19, 2008 by admin
Volvo will show the new S60 Concept car at the Detroit Auto Show this January. The car will be featuring a new 180 hp (134 kW) four-cylinder 1.6-liter gasoline engine using high-efficiency GTDi (Gasoline Turbocharged Direct Injection) technology.
In combination with a range of other measures such as stratified combustion and stop/start, this engine makes it possible to cut carbon dioxide emissions to 119 g/km (5.0 L/100 km, or 47 mpg US). Volvo Cars’ first production car with the GTDi technology will be introduced during the second half of 2009.
The technology promotes better gas flow with optimized air/fuel mixture and greater resistance to uncontrolled combustion. The result is higher power and lower fuel consumption. GTDi technology combined with turbocharging makes it possible to reduce engine displacement with maintained performance, but with about 20% lower fuel consumption and CO2 emissions.
In addition to GTDi technology, the Volvo S60 Concept integrates the following technical features to bring CO2 emissions down to 119 g/km:
Stratified combustion. The combustion chamber is designed such that a mist consisting of the optimal blend of air and fuel is formed around the spark plug, surrounded in turn by pure air. This allows the engine to operate with a surplus of air, thus cutting fuel consumption.
A stop/start function.
Dual clutch transmission.
EPAS (Electric Power Assisted Steering). In principle an “electric servo” where the conventional hydraulic pump has been replaced by an electric motor linked directly to the steering system’s gear rack.
DRIVe-Mode. Gives the driver the possibility of reducing fuel consumption via an economy mode that limits the function of a number of selected electrical or mechanical systems. This may for instance include the air conditioning, cruise control or automatic transmission gearchanging settings.
Grille shutter. A wind-deflecting panel that can be closed to reduce air drag when there is less need for cooling air.
Flat underbody panels.
The use of lightweight materials in the car body.
