GM execs fired over fraudulent India emissions testing

General Motors hadn't had a recall in India since 1995. That changed when it was discovered that certain employees were playing tricks with local emissions testing in order to ensure passing grades for engines. More than ten GM Powertrain employees in India and the US have been let go over the ensuing emissions flap, including Sam Winegarden, VP of global engine engineering, a man who has been with the company since 1969, leading development of some marquee powerplants.
According to Automotive News, an internal investigation revealed that employees "violated testing procedures," sometimes swapping specially prepared low-emissions engines during testing regimes for the Chevrolet Tavera SUV equipped with the 2.0-liter and 2.5-liter engines. Employees were also manipulating weights in order to get vehicles placed into different emissions categories. The discovery has led to GM recall the 114,000 Taveras produced over an eight-year period and halting their production and sale.
The Economic Times of India reports that the issue is due to "a faulty component." GM has developed a solution to the issue, and once it is validated in testing and approved by the Indian authorities, the recalled vehicles will be fixed at dealers and production will resume.

GM wants to have 10 plug-in models in China in five years

Last we checked, General Motors was selling all of three plug-in vehicle models in its home country of the US, and is prepared to make the Chevrolet Bolt EV available on these shores later this year. So it's notable that the automaker is hatching plans to have at least 10 plug-in variants for sale in China within the next five years, according to Hybrid Cars. Which plug-ins are coming remains a mystery. GM started selling a hybrid version of the Buick LaCrosse in China this month. The strategy makes sense, as China is now the world's largest car market, and accounts for about a third of GM's annual revenue. The automaker, which operates in China under the SAIC-GM and SAIC-GM-Wuling joint ventures, sells cars there under the Chevrolet, Buick, Cadillac, and Boujun badges, and has been doing so for the better part of two decades. Most recently, GM started selling a hybrid version of the Buick LaCrosse in China this month. What we do know is that GM is building its Cadillac CT6 Plug-in Hybrid in China, with distribution to be split between China and the US. That model, which is scheduled to start sales by the end of the year, is being built overseas because of a combination of Chinese government support for new-energy vehicle technology through incentives and the fact that battery-pack maker LG Chem makes most of its cells in nearby South Korea. The plug-ins are part of a broader plan by General Motors to either introduce or substantially tweak about 60 models by the end of the decade. With such new models, GM looks to boost unit sales by as much as five percent a year for the next few years. As for the other nine plug-in models slated for China by 2021, the company is mum. GM spokesman Dan Flores declined to comment to AutoblogGreen.

2016 Chevy Volt arrives with 50-mile EV range, 41 mpg [w/ video]

Let's start with the numbers. The 2016 Chevy Volt will have an all-electric range of 50 miles from a new, 18.4-kWh lithium battery. It will get 41 miles per gallon (combined) once the battery runs dry and have 102 MPGe. Oh, and it has five seats, sort of. To compare, today's four-seat 2015 Volt has a 38-mile range from a 17.1-kWh battery in a powertrain that offers 37 mpg and 98 MPGe. So, across the board, there are notable improvements. Now that that's out of the way, let's talk story. General Motors will unveil the new Volt at the Detroit Auto Show later today, but it's been talking about how this new version – the first major plug-in hybrid vehicle to get a serious redo in the modern era – was crafted with reams and reams of data from first-gen Volt customers. At a preview event for journalists last week, GM executive chief engineer Pam Fletcher told Autoblog that these owners "gave us the recipe" to make the second-gen model. At the top of the request list was more range (check), more "fun-to-drive" behavior (check?) and a smoother and quieter experience (we'll assume a check here, given that the new 1.5-liter four-cylinder – the first North American application of this new engine family – should offer more power with less noise than the previous 1.4-liter, four-cylinder powerplant). Other customer-driven changes in the new Volt include a different place to store the charging cable (in the side of the trunk instead of under the load floor) and a new brake system with improved blended regenerative braking feel as well as driver-selectable regen levels. The requested 50-mile range comes from a new, lighter battery that has increased capacity from fewer cells (192 vs. 288) and a simplified control architecture. Along with the new battery, the electric drive unit is a two-motor deal that is up to 12 percent more efficient and 100 pounds lighter, while also being "tremendously smaller," notes Fletcher. It offers 294 pound-feet of torque and a maximum 149 horsepower of "motoring power" delivered to the wheels. GM says it has worked hard to reduced the amount of rare earth materials in these motors, and one of them doesn't use any at all. The new powertrain offers improved acceleration times, as well. The 2016 Volt can go from 0 to 60 miles per hour in 8.4 seconds, a seven-percent improvement, while the 0-30 mph time has been improved by 19 percent, down to 2.6 seconds. The new Volt is more conventional looking, but certainly not completely ordinary.
