Cadillac ELR

Back in 2009 Cadillac (GM) exhibited their Converj electric-hybrid concept car, a couple of years later they revealed the updated and renamed ELR electric-hybrid.  At the North American International Auto Show earlier this month GM unveiled the production ELR which will use the drivetrain from the Volt - a 120 kW electric motor coupled to a four-cylinder engine-generator.  According to GM the 16.5 kWh battery should provide around 35 miles electric-only range with a total range of 300 miles including the petrol engine.  Charge time at 240V will be 4.5 hours (charging station) and at 120V a surprisingly long (considering the tiny battery) 12 hours.  Is it just a Volt with make-up?  Seems so, pity.

GM China Advanced Technical Center

SAIC (Shanghai Automotive Industry Corporation) and General Motors today signed an agreement to co-develop 'a new electric vehicle architecture in China' as well as opening the first phase of their joint Advanced Technical Center (PATAC) which will provide R&D on technologies such as batteries and electric drivetrains.  As well as being a major development center for GM the agreement and center provide them with a 'foot in the door' to the lucrative Chinese electric vehicle market and will no doubt make the newly developed vehicles eligible for inconsiderate Chinese government electric car grants.

GM battery engineering team

General Motors has announced that it has awarded A123 Systems a production contract for their advanced Nanophosphate lithium-ion batteries (and related systems).  Obviously at this stage General Motors aren't saying what project these batteries will be used for but it's safe to assume it'll be for an upcoming GM plugin-electric vehicle. “GM is committed to offering a full line of electrified vehicles - each of which calls for different battery specifications,” said Micky Bly, GM’s executive director - Global Electrical Systems, Infotainment and Electrification. “We work with a variety of battery developers and A123’s advanced Nanophosphate lithium ion technology offers ideal performance capabilities for a future electrified vehicle application.” More »

In a joint venture with DTE Energy General Motors will soon have a 264,000 square foot solar array field which should generate 516 kW, enough to charge over 50,000 Volts (150 per day).  DTE's investment in the project runs to no less than $3 million which will take around 200 years to recoup at the "$15,000 a year" GM estimates it will save them.  Still, it's a baby step away from reliance on fossil fuels. “This array will significantly decrease energy consumption by combining solar power with ongoing efficiency tactics such as lighting and equipment upgrades and automating equipment shut-down,” said Bob Ferguson, vice president of GM Public Policy. “Making sustainable choices is good for both the environment and our bottom line. Obviously cost savings is critical for GM, and the ability to save $15,000 per year while being environmental serves us well.”More »

Some hopeful and interesting news out of General Motors today, they're waving the PR flag over their HR department which is kind of unusual, but for good reason.  As of today they wish to add 1,000 engineers and researchers dedicated to electrical vehicle development.  This covers the range of EV related work including batteries, motors and power control units.  We hope there's real conviction behind the PR spin and that GM are serious about developing a real plug-in battery-only electric vehicle (not a hybrid) in the futre. GM CEO Dan Akerson said, “GM is going to lead the industry in the adoption of various vehicle electrification technologies, whether its electric vehicles with extended-range capability, like the Chevrolet Volt, or the recently introduced eAssist technology that will debut on the 2012 Buick LaCrosse,” Akerson said. “We want to give our customers energy choices other than petroleum and to make the automobile part of the solution when it comes to the environment."More »

Timelapse video of the construction of the Chevrolet Volt

General Motors has posted a timelapse video of the construction of the 2011 Chevrolet Volt at the Detroit-Hamtramck plant, in it you can see the large 'T-shaped' battery being inserted into the space which would be the transmission tunnel and then the entire drivetrain being connected up afterwards.  We will continue to cover the Volt here on zemotoring despite the revelation that it is really a range-extended hybrid - the Volt's petrol engine is mechanically connected to the drive under heavy acceleration.  The entire auto industry and consumers who placed pre-orders were under the impression that the car was only driven by its electric motor and that the petrol engine was used to recharge the batteries.More »

GM continues to be bullish about the Volt, today announcing that they will provide an eight year or 100,000 mile warranty on its battery packs.  According to their press release "GM engineers have completed more than 1 million miles and 4 million hours of validation testing of Volt battery packs since 2007, as well as each pack’s nine modules and 288 cells. The development, validation and test teams have met thousands of specifications and validated each of the Volt battery’s components.

Tests include short circuit, corrosion, dust, impact, water submersion, crush and penetration, and extreme temperature swings combined with aggressive drive cycles, also known as  “Shake, Bake and Roll.”More »

General Motors, who will obviously be hoping everyone has forgotten the EV1 debacle (where they were effectively complicit, along with many other interested parties in the delaying of development of electric vehicles), are now happy to put plenty of spin on their upcoming Chevrolet Volt plug-in hybrid.  On the official Chevrolet YouTube channel they've posted a series of videos on the development of the Volt, including a speech by GM CEO Ed Whitacre and a Volt ad which carries the tagline "That's the sound of the status quo crumbling" (oh, the irony).  Click through to watch.More »
