Gov. Granholm gets into a Chevy Volt – Click above for high-res image gallery

The way General Motors will deal with the separate emissions regulations for California and the rest of the U.S. is by offering the Chevrolet Volt in at different powertrain flavors by 2012. Tony Posawatz, the vehicle line director for the Volt, explained these three slightly different powertrains to AutoblogGreen:
  • First, we'll have the standard, 50-state Volt that is coming out later this year.
  • We'll also get a version that meets California's Enhanced Advanced Technology Partial Zero Emissions Vehicles (enh-ATPZEV) standard
  • Finally, there will be an E85-capable Volt
We've heard about all of these models before, but Posawatz said GM will introduce the enhAT-PZEV Volt in early 2012 – or "around that time frame" – and that the vehicle will qualify for HOV lane access in California. Another tweak is that the enhAT-PZEV rules require any car with that designation to have a battery with a 10-year, 150,000-mile warranty, "and we have no problem with that," Posawatz said. The standard Volt battery will have an 8-year, 100,000-mile warranty. Anyone in the U.S. will be able to check a box on the Volt order form and order the enhAT-PZEV package, but pricing for this version and other details have not been decided.

Posawatz also talked about how the Volt will attempt to prevent overloading the local grid. The Volt's software charging options allow drivers to set up a "charge by departure time." This option will then pick a random time between the present and your departure time to start charging the battery. By choosing a random time, instead of kicking in as soon as nighttime rates begin, the system will stagger the times when all the plugged-in cars on the block draw down a lot of juice. In effect, Posawatz said, this will prevent a new evening spike while still making sure your car has a full battery when you need it for work in the morning. This is not a new idea (see an in-depth paper on the idea here), but it is a good one.
