On April 1, new federal fuel economy CAFE standards went into effect. By 2016, new cars should get 35 mpg or thereabouts. The true number remains an exercise in abstract algebra. Says Consumer Reports: “The new standards require different fuel economy averages for each manufacturer and for each type of vehicle (such as small, midsized, and large sedans or SUVs).” There are plenty of loopholes and offsets. Extra credit for cars that take E85 Ethanol, for instance. And here is another huge loophole:

It’s been said many a time that the problem with hydrogen as an energy storage system for cars is that it is always the future and never the present of transportation. Indeed, hydrogen has nearly fallen of the alt-fuel radar in recent years, as present-techs like hybrid and even electric drive have matured. But the dream is not dead. The great hydrogen hope now lives with General Motors, in the form of a new, lighter-weight fuel cell which GM says will be production-ready by 2015. The new cell is 225 lbs lighter and uses one-third less platinum than the systems being tested in GM’s 30-month “Project Driveway” Equinox fuel-cell vehicles (FCVs). That leaves more platinum for trimming Escalades, and has GM thinking that real-life series production of FCVs could be possible. GM’s Charles Freese tells Automotive News [sub]:

Our learning from Project Driveway has been tremendous. The 30 months we committed to the demonstration are winding down. But we will keep upgrades of these vehicles running and will continue learning from them while we focus efforts on the production-intent program for 2015. We will continue to use the Project Driveway fleet strategically to advance fuel cell technology, hydrogen infrastructure and GM’s vehicle electrification goals
