Volvo has finally released images of the Volvo S60 Concept car which will be unveiled at the Detroit Motor Show in January. The Concept, which we originally previewed here, gives an indication of what the all-new Volvo S60 will look like when launched in 2010. Apart from the previously mentioned floating centre stack made out of handmade, solid Orrefors crystal, the car features a four-cylinder 1.6-litre petrol engine using high-efficiency GTDi (Gasoline Turbocharged Direct Injection) technology and producing 180 horsepower. In a conventional petrol engine, fuel is injected into the inlet manifold ahead of the inlet valves. With direct injection, however, the fuel is injected directly into the combustion chamber under high pressure. The vehicle also has an upgraded version of Volvo's Adaptive Cruise Control (ACC) with a queue assist function. The radar-based Adaptive Cruise Control maintains the set time gap to the vehicle in front all the way down to standstill, meaning the car can drive itself in slow-moving queues with repeated starting and stopping.
