|The new V70 wagon.|
Volvo will introduce the third generation of its V70 wagon at the upcoming Geneva auto show. The redesigned model will offer a new version of the five-cylinder D5 diesel, a four-cylinder flex-fuel option, and a new top-end six-cylinder twin-scroll turbo engine.
The second-generation D5 five-cylinder diesel option delivers 136 kW (185 hp) of power and 400 Nm of torque across a wide rev range. The new D5 features a new electronically controlled turbocharger, more advanced multi-point injection technology and new engine management system. A diesel particulate filter is standard. Estimated fuel consumption is 6.5 l/100km (36 mpg US), with CO2 emissions of 173 g/km.
The Volvo V70 will be available in an FlexiFuel E85 alternative during its first production year. The FlexiFuel model uses a four-cylinder naturally aspirated engine producing 108 kW (145 hp). Further figures on the E85 model will come closer to release.
The new six-cylinder gasoline engine is based on the compact 3.2-liter in-line aluminum engine introduced in the new S80 in spring 2006. While the naturally-aspirated 3.2-liter version is available in the V70, a new, slightly downsized 3.0-liter turbo version is available as the top performing unit.
The smaller displacement in the 3.0-liter engine—due to the slightly narrower cylinder bore and shorter stroke—is offset by the twin-scroll turbocharger, which divides the inflow into two lots of three cylinder each.
Twin-scroll technology permits use of a more compact and uncomplicated turbocharger and provides response on a par with that of conventional twin turbochargers. The 3.0-liter turbo produces 210 kW (285 hp) of power and 400 Nm (295 lb-ft) of torque. Volvo’s preliminary rating of fuel consumption (combined) is 11.2 l/100km (21 mpg US), with CO2 emissions of 267 g/km.
The 3.2-liter normally aspirated engine produces 175 kW (238 hp) of power and 320 Nm (236 lb-ft) of torque. Preliminary fuel consumption is 10.3 l/100km (22.8 mpg US), with CO2 emissions of 246 g/km.
The engine also has a valve system with dual cam profiles on the inlet side. With CPS (Cam Profile Switching) the inlet valves can be lifted to two different heights in response to variations in engine revs and load. The engine also features a variable intake system (VIS) consisting of two throttle valves that adjust the volume of the inlet manifold to suit the current driving conditions.
