Honeywell Transportation Systems Forecast: turbocharged vehicles to account for 48% of annual global sales by 2021; electric boosting emerges

Green Car Congress

This annual sales estimate, combining both passenger and commercial vehicles, would add more than 232 million turbocharged vehicles globally between 2017 and 2021—an increase of 35% from today. Regional highlights include: In North America, more engine downsizing is expected. The current average engine size is a 3.0-liter

The EU has already set a standard for 6 × 10 12 number/km limits between 2014 and 2017, tightening to 6 × 10 11 number/km.). Homogeneous GDI provides fuel efficiency benefits from charge air cooling, more facile turbocharging, and the downsizing that these permit. —Maricq et al. Credit: ACS, Maricq et al.

Calls for an international 48V electrical standard for vehicles; looming WLTP implementation

Green Car Congress

the Worldwide harmonized Light vehicles Test Procedures (WLTP). The EU goal is to introduce the WLTP by 2017 if possible and no later than 2020 to coincide with the 95 g/km requirement. This means that in addition the power demand is more difficult to achieve with engine downsizing and transmission down-speeding alone.
