In Week One, I did most of our driving at 55 mph, so for Week Two, I slowed down to 50 mph and then in Week Three, I kicked it up to a cruising speed of 60 mph. My driving percentages for the first two weeks were nearly identical, but dropped noticeably (-15%) in the third week—so the bump up to 60 mph is significant in terms of efficiency.

GM spokesperson Rob Peterson confirmed to Automotive News that Volt "ordering is down," which he says is due to a "lot of misinformation that has swirled over the past month." Select Chevrolet dealers from New York to California are reportedly turning down Chevy Volts until the negative media buzz dies down.

Beginning on February 6, General Motors will manufacture Chevy Volts that meet California's e-AT-PZEV status, thus enabling the Volt to qualify for the state's highly coveted green High Occupancy Vehicle (HOV) stickers.

It has been an interesting and exciting first week for our High School Environmental Science - Chevy Volt Project. We drove several extra short test trips, as quite a few people were anxious to get behind the wheel to see what it’s all about. "I had heard about the Chevy Volt for a while. I had envisioned that it must be like driving a really nice electric golf cart," said Brennan Riffle, our driving instructor at Sterling High. "After having a chance to drive the Volt, these preconceived notions were shattered."

US safety regulators, including representatives from the National Highway Traffic Safety Administration (NHTSA), are apparently satisfied with the set of Chevrolet Volt modifications detailed last week by General Motors. The NHTSA will "conclude its investigation soon," according to Agency administrator David Strickland.
