Stringent emissions standards, such as the US mandate for 54.5 mpg corporate average fuel economy by 2025, is pushing the forecast. Another anticipated market force is sales growth in emerging markets, where smaller vehicles make up most of their volume. Small cars, like the Scion iQ (pictured) and the Ford Fiesta, will drive much of this growth, but B- and C-size crossover utility vehicles (CUVs) will continue to play a large role in smaller engine vehicle sales around the world. WardsAuto predicts that 2.0-2.9-liter engine vehicles in things like CUVs, pickups, SUVs and vans, will also make up a large chunk of the vehicles sold around the world.
Government policies on fuel economy standards and CO2 emissions reductions are built on lighter, highly fuel efficient vehicles growing in sales volume. There's also a lot of hope for electric vehicle sales growing to help meet those targets. WardsAuto/AutomotiveCompass thinks EV sales will go up in volume and will outsell large 4.0-4.9-liter or 5.0-liter-plus light-duty vehicle in sales volume through 2020.
