Watch this time-lapse build of the Chevy SS for NASCAR

There's only about a week left until we get our first look at the production version of the 2014 Chevrolet SS sedan, but Chevrolet NASCAR teams have been looking at the race version of the car all winter. Autoweek has posted a really neat time-lapse video showing just a portion of what it takes to build one of NASCAR's new Gen6 stock cars.
Though the video is quite brief, it does show almost the entire build process starting with just the car's nose, and it gives us a good look at how integral the template is to the final product. As a bonus, Hendrick Motorsports also provided some videos showing two of its teams performing pit stop tests over the winter. The second video shows some of the more detailed aspects of the racecar's rear end, including the stock-looking trunk cutout and a newly mandated rear bumper extension that will be used on super speedways like Daytona and Talladega.
To see what Team Chevy has been up to all off-season, check out all three videos posted after the jump.

Why the Corvette's Performance Data Recorder can be illegal in some states

The Performance Data Recorder with Valet Mode available on the 2015 Chevrolet Corvette Stingray seems like a fantastic tool for many owners. Whether they are taking 720p video while lapping the track in their new 'Vette, or just want to protect their purchase from inconsiderate joyriders, the system offers a lot of functionality in one package. However, one of the PDR's features might get buyers in trouble with the law, and it has nothing to do with recording some illicit high-speed driving on a favorite back road. The problem hinges on the various state laws concerning a person's right to privacy.
According to a letter posted by Jalopnik, Chevy dealers are asking 2015 Corvette owners not to use the Valet Mode portion of the PDR because it records audio in the cabin, in addition to performance specs. That's a problem because privacy laws vary from state to state with some requiring just one side's consent to tape sound and others requiring all parties to agree. According Jalopnik, 15 states mandate everyone's permission beforehand, but it's not clear whether these numbers are up to date. (Actually, the report varies, saying 13 states in some places and 15 in a list.)
According to the letter, Chevy is already working on a software update for the near future to rectify the issue. It's possible that simply adding a warning to drivers and the ability to turn off the audio recording function in Valet Mode might solve the problem. Obviously, this doesn't preclude Corvette drivers from using the performance aspect of the PDR, and owners are free tape lap after lap at the track.

Recharge Wrap-up: Range-extended EV taxis in London, 2016 Chevy Volt interior two years old

The first Metrocab range-extended EV taxis are operating on the streets of London. The cabs use a 12.2-kWh battery and two 50-kW motors, as well as a 1.0-liter gasoline range extender. Fuel economy is 98 MPGe on the ECE101 cycle, and total driving range is over 348 miles before needing to charge or refuel. Cabbies can expect to save GBP20 to GBP40 (about $30 to $60) per day on average. "The cash savings on fuel are significant, the ride and comfort outstanding, and my first customers are thrilled with the new cab," says the first operator of the new EV taxi, Preston Morris. "With its air suspension providing unrivaled comfort, panoramic glass roof for views of the city and silent powertrain, what's not to like?" Read more in the press release below. Chevrolet has had the interior design of the 2016 Volt finished for two years already, according to GM interior designer John McDougall. Beginning around 2010, GM received sketches from designers worldwide before narrowing it down to a handful of designs. Then the top three choices were molded from clay. The chosen theme was then refined for up to 18 months. "Every little thing you can imagine goes into that," says McDougall. "The glare angle from the windows, the placement of the controls, the placement of the seat. You have to create something that's beautiful and functional."

Vattenfall has announced a research project in partnership with BMW and Bosch to use retired EV batteries for stationary, grid-connected energy storage in Hamburg, Germany. Over 100 lithium-ion batteries from BMW i3 and ActiveE vehicles will make up a two-mWh storage unit for grid balancing, enough to power 30 four-person households for a week. The system is "compact enough to fit in a small building," says Bosch. Such storage systems are especially fit for storing and moving alternative forms of energy, which often fluctuate in supply more than electricity from a traditional power plant. Vattenhall will operate the storage unit for 10 years, with Bosch managing the batteries, during which time the three partners hope to learn more about battery applications and their performance over time.
