As before, the new 119-gram versions of the Volvo V70 and S80 are equipped with a 1.6-litre diesel engine and manual gearbox. They have a power output of 109 hp and maximum torque is 240 Nm.
Volvo's driveline experts have employed two techniques to reduce CO2 emissions from the previous 129 g/km (4.9 l/100 km) to 119 g/km (4.5 l/100 km):
* Intelligent battery recharging, whereby the control system only allows the alternator to charge the battery when the engine is operating at low load, for instance when driving downhill.
* Reduced friction for the belt that drives the alternator and air conditioning compressor. The redesign of the tensioner pulley and alternator pulley results in lower fuel consumption and lower emissions.
The reduction in fuel consumption from 4.9 l/100 km (mixed driving cycle) to 4.5 l/100 km means that someone driving 15,000 km a year will save 60 litres of diesel. Translated into carbon dioxide emissions, the saving is 150 kg over a year.
