General Motors (GM) has outlined its product goals and progress towards its ambitions for 2020 as part of a newly released sustainability report: and has revealed an ambitious target for fuel economy.
It has outlined three commitments for 2017 relating to its sustainability strategy. These are:
- To have at least 500,000 vehicles on US roads with some form of electrification.
- To reduce the CO2 emissions of its US fleet by at least 15 per cent.
- To double the number of US models capable of an estimated 40mpg or better.
While these goals apply to its fleet in the USA, its goals in Europe for the Opel/Vauxhall brand are even more eye-catching: with the brand aiming to reduce average CO2 exhaust emissions by 27 per cent by 2020.
So how close is GM to achieving these targets?
Currently, the carmaker has several electrified cars on the road in the USA. The most notable is of course the headline-stealing Chevrolet Volt; but it is joined by the Chevrolet Spark EV (pictured), the Buick LaCrosse, Regal, Chevrolet Impala and Chevrolet Malibu with eAssist.
As for its goal of 40mpg fuel economy it already has several vehicles meeting this target. They include the Chevrolet Volt and Spark EV as well as the Sonic, Cruze Eco and the Cruze Diesel.
Going forward, its fuel economy is set to focus on reducing vehicle mass and investing heavily in advanced materials: which will include carbon fibre; aluminium; and high strength steel. It will also focus on thermodynamic efficiency in its petrol engines and use a suite of technologies that incorporate direct injection, turbocharging, cylinder deactivation and variable valve timing. It is hoped that these technologies can help reduce fuel consumption by 18 per cent and CO2 emissions by 15 per cent.
