Peugeot has a serious commitment to reducing its carbon footprint and at the end of May 2013 its average emissions across its range were 116.3g/km – down from 121.5g/km in 2012.According to the automaker it has achieved this through its on-going optimisation of internal combustion engines, improved efficiency, downsising and adding technologies like Stop/ Start and diesel-electric hybrids.The automaker said: “New generation engines like the 'family of one' and 1.2-litre three-cylinder petrol engines has also played a key role.”At the 2013 Frankfurt International Motor Show, the automaker will showcase its new BlueHDi diesel emissions control technology on its new 308 and 508 SW. The automaker said: “The technology combines ‘selective catalytic reduction’ (SCR) and diesel particulate filtration with additive (FAP) which reduces NOx emissions by up to 90% to optimise CO2 emissions and fuel economy while eliminating 99.9% of particulates.“Peugeot’s BlueHDi technology already complies with the Euro 6 diesel standards and will be extended from the end of 2013 to all of the marque’s diesel models.”NEXT-GENERATION HYBRIDSAlso on display in Frankfurt will be the automaker’s HYbrid4 diesel-electric hybrid technology, introduced in its 3008 HYbrid4, then extended to the 508 RXH and 508 Saloon HYbrid4. These three HYbrid4 models have already found more than 28 000 homes worldwide.HYBRID AIRThe 2008 HYbrid Air is a vehicle which combines a petrol engine and a compressed air powertrain. The powertain recovers energy lost in braking and deceleration and the technology will be applied to B and C segment cars from 2016.Advanced technologies are also explored in the 208 HYbrid FE “demonstrator”, developed in partnership with Total. The car emits 49g/km yet can accelerate from 0-100km/h in eight seconds.Back to the main story. Stay with Wheels24 for the 2013 Frankfurt Motor Show.
