DETROIT, Michigan - General Motors wants to have at least eight of its vehicles returning 5.8 litres/100km by 2017 as part of its efforts to decrease fuel consumption and reduce emissions.The Detroit News reports that the automaker, in its 2012 sustainability report, said it wants to double the four vehicles it has with a such a low consumption - Chevrolet Volt, Cruze Eco, Sonic hatchback (turbo) and Sonic sedan.The new Chevrolet Cruze diesel, Spark EV and Cadillac ELR (both electric-assisted cars) will be launched in 2014 to take the total to seven.UNDER PRESSUREChrysler Group's Dodge Dart Aero and parent brand Fiat's 500 EV (electric vehicles) met the 5.8 requirement.Ford has eight models that achieve 5.8 or better - C-Max Hybrid, C-Max Energi plug-in hybrid, Fusion Hybrid, Fusion Energi plug-in hybrid, Lincoln MKZ Hybrid and Focus Electric as well as Focus and Fiesta models equipped with specific packages - most of those cheating on real fuel consumption because they have battery assistance.Ford spokesman Mark Schirmer said: “We’re going to make every effort to increase that number and maintain our lead."Automakers are under pressure to meet US corporate average fuel economy fleet standards of 6.6 litres/100km by 2016 and 4.3/100 by 2025, the DetNews reported.GM spokeswoman Sharon Basel said: “We’re not saying we would lead the industry (on having the most vehicles with figures of 5.8) but rather setting a commitment based on our projections and portfolio plans and willing to be transparent in how we get there and report our progress along the way.” By 2016, GM wants to reduce emissions produced by 2011 model year vehicles by 15%. The automaker also wants to cut Opel emissions by 27% in Europe by 2020.500 000 GREEN VEHICLESIn January 2012 GM rolled out its first sustainability report. It listed nine environmental goals, including reducing waste, energy, carbon and water use at manufacturing sites, and boosting the number of landfill-free facilities by 2020. GM said it has cut the energy required to build a vehicle by 7% since 2010, saving R660-million. (Wonder if that was passed on to customers? - Editor). The company also adds about R9-billion (or that!) in revenue annually as it recycles and re-uses 90% of its manufacturing waste globally. GM said it has been able to cut total waste per vehicle by 24.9kg since 2010.GM’s goal is to have 500 000 “green” vehicles in the US by 2017 through a mix of hybrids, plug-ins and electric vehicles. The company said it had 179 801 EV units (which is 0.07% of the national car park) on the road in 2012, up from 48 108 in 2011.
