Ricardo testing finds DPF regeneration spikes particulate emissions, resulting in exceedance of Euro limits

Green Car Congress

Testing of two popular Euro 6d-temp diesels by Ricardo, commissioned by the environmental NGO Transport & Environment (T&E), has found that the periodic regeneration of diesel particulate filters (DPFs) in the light-duty vehicles can generate spikes of particulate emissions of more than 1,000 times the normal rate.

California ARB approves ACC II rule; 100% of LDVs to be PHEVS, ZEV by 2035; LEV IV emissions requirements

Green Car Congress

The rule establishes a year-by-year roadmap so that by 2035 100% of new cars and light trucks sold in California will be zero-emission vehicles (ZEVs) and plug-in hybrid electric vehicles (PHEVs). It does not impact existing vehicles on the road today, which will still be legal to own and drive.

EPA, NHTSA issue One National Program Rule; EPA withdraws CA waiver for GHG and fuel economy

Green Car Congress

This action is based on the premise that federal law preempts state and local tailpipe greenhouse gas (GHG) emissions standards as well as zero emission vehicle (ZEV) mandates. California’s ability to enforce its Low Emission Vehicle program and other clean air standards to address harmful smog-forming vehicle emissions—i.e.,
