Continental XL3 solenoid injector in production in 1.5L GDI engine; looking ahead to Euro 6c

Green Car Congress

Compliance with future emissions standards such as Euro 6b (from 9/2014) and Euro 6c (from 9/2017) will call for further improvements in engine combustion processes. Precision metering, combined with multiple injection capability, helps to reduce the particulate emissions of GDI engines and can cut the costs of aftertreatment technology.

Industry survey finds aluminum use in autos at all-time high; average per vehicle use expected to more than double from 2012 by 2025

Green Car Congress

Using aluminum will extend the efficiencies of other technologies, while enabling secondary cost-savings from downsized powertrains without sacrificing performance. For example, the trend line for aluminum hood penetration predicts a minimum share for aluminum of 41% by 2017 and 53% by 2025. kg) per year per light vehicle.

Center for Automotive Research calls long-run economic risk to auto industry of mandating permanent fuel economy standards very serious; recommends periodic reviews

Green Car Congress

Each of these nine pathways produced a specific fuel economy standard and cost estimate measured at retail price equivalence. CAR did not assume any downsizing of the vehicle sales fleet or significant reduction in performance by vehicles in any segment as a means for increasing fuel economy standards by 2025. 51 mpg, by the year 2025.
