CNG Chevy Impala launch delay grows to a year

The 2015 Chevrolet Impala Bi-Fuel was announced in Washington D.C. in late 2013 by Dan Akerson and was supposed to be on sale by the summer of 2014. Capable of running on gasoline and compressed natural gas, the sedan was said to offer a novel solution at a time when gas prices were high. The vehicles still haven't arrived at dealers, though, and according to Automotive News, a quality issue has set back the launch even a few months more. Using a modified 3.6-liter V6 with hardened valves and valve seats, the Bi-Fuel Impala has separate tanks for gasoline and CNG that it can switch between on the fly. When running on the cheaper natural gas, the sedan was estimated to get 19 miles per gallon in the city and offer 150 miles of range, and the total driving distance was predicted at around 500 miles. The base price was set at $38,210, after the $825 destination charge. The only other major tradeoff was a smaller trunk to accommodate the extra fuel. However, the first shipments of the bi-fuel models now aren't expected until mid-July – about a year later than the scheduled launch. A memo to dealers obtained by Automotive News said the sedan "has been delayed by a second quality hold" to look at the CNG system. The exact details surrounding this problem haven't been released. "We have identified a solution to the delay and are working hard to implement it within the next few months," General Motors spokesperson Chad Lyons said to Automotive News. Around 200 Bi-Fuel Impalas have been made, but none are yet in the hands of customers. Dealers should be able to order 2016 model year examples starting in the third quarter of this year.

More Corvette Stingray Factoids: Vanishing panel gaps and 26-mpg LT1

During January's Detroit Auto Show, we managed a longer than expected wandering tag-team interview with C7 Corvette chief engineering exec Tadge Juechter (pictured above), and LT1 engine boss Jordan Lee (pictured below). They are, quite honestly, two of the very nicest bigshot lads to ever walk the engineering corridors of an American manufacturer. Both are enthralled by what they're doing for a day job. So are we.
We've followed the pre-sale anticipation for the Chevrolet C7 Corvette Stingray like an Oreck vacuum yanking every speck of dirt from a well-trampled carpet. Everything is reportable and contains a grain of further knowledge about this dramatically important and cheered-for car, as it continues to be pressured into representing all that is superior about the American dream. The Corvette wears one heavy cloak.
So, most of what was talked about has been expertly reported already right here on Autoblog. But, looking through our notes again, both Jeuchter and Lee added facts to the buzzing mix.

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.
