EPA report: EVs are beginning to have a “measurable and meaningful impact”
The most recent edition of the EPA’s annual report Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends notes that alternative fuel vehicles (including EVs, PHEVs and CNG vehicles) are beginning to have a “measurable and meaningful impact” on the fuel economy and CO2 emissions of the country’s passenger car fleet. The EPA report,… Read more »
Will European drivers warm to hybrids?
Hybrids, with or without plugs, are comparatively rare on European roads, but Automotive News believes that’s about to change, as EU limits on CO2 emissions become stricter, forcing Continental automakers to electrify. German and French automakers dominate the market in Europe, and diesels have long been their chosen solution, accounting for half of new-car sales… Read more »

Ultracapacitors supercharge stop/start systems
Electrification is quietly sneaking into “conventional” vehicles, as more models incorporate stop/start technology. Navigant Research predicts that 54% of new vehicles worldwide will have stop/start capability by 2022. Different automakers are applying stop/start in very different ways. For energy storage, a stop/start system may use Li-ion batteries, advanced-glass-mat (AGM) lead-acid batteries, ultracapacitors (UCs), or some… Read more »
