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.

2016 Chevy Volt powertrain technical details

The last time General Motors launched a Chevy Volt, it was operating without really knowing how people would use the plug-in hybrid. Sure, it had experience with the EV1, but the Volt was a new kind of car, and you can see in the archives just how much time GM spent explaining this fresh, new powertrain to potential customers. Then, once the vehicle was released, the company collected voluntary data from a large number of owners to learn about their driving and charging habits. The company also asked them what they wanted most in the new version. There's got to be an algorithm buried somewhere in GM headquarters that was used to take all of the numbers GM collected and spat out the headline figures for the 2016 Volt: 50 miles of EV range and 41 miles per gallon. Another important number – price – is something GM isn't talking about yet (expect it in April or May), but the company is sharing some powertrain details about the upcoming car. At a preview lunch in Detroit last week for the SAE 2015 Hybrid & Electric Vehicles Technologies Symposium that's happening now in California, GM engineers Peter Savagian (who is presenting a paper on the new inverter used in the updated Volt) and Tim Grewe (talking about the entire second-generation powertrain) sat down with AutoblogGreen to tell us about the Volt's all-new propulsion system: The overall gist is that the new Voltec 5ET50 drive unit is lighter, smaller and more powerful thanks to a redesigned two-motor traction drive. As previously reported, the new engine is a 1.5-liter DOHC four-cylinder that offers 101-horsepower (at 5,600 RPM). Grewe said it's "great for range extension." The electric motor side of the powertrain offers 149 motoring horsepower from a two-motor, continuously variable transaxle. Initially, the new engine will be made in Mexico. GM will move production to Flint, MI during the first year it makes the 2016 Volt. The battery is slightly bigger in the new Volt – 18.4 kWh compared to 16.5 in the current-gen – and will have less range variation in the cold. GM is also using more of the overall capacity in the pack in the 2016 Volt than in previous versions, but is not saying how much more. GM is not ready to publish acceleration times just yet, but the 2016 Volt has improved numbers, especially when going from 30-60 miles per hour. Most everything on the new powertrain has become more efficient compared to the first-gen Volt.

Michael Jordan's cars showcased in 'The Last Dance' documentary

After the masses begged and pleaded for an early release, ESPN finally unlocked the doors to the biggest production in company history last month. Episodes 1 and 2 of The Last Dance, a 10-part documentary special about Michael Jordan, the Chicago Bulls, and the 1997-1998 season, was released at last on April 19, 2020. Each week since, two new episodes have aired on Sunday nights, and the next two, episodes 7 and 8 are scheduled to drop this weekend on May 10. With unprecedented video access to MJ, who became averse to the media during his playing days, a byproduct from The Last Dance is a look at some of Jordan's cars. The Goat's taste ranges across a number of brands, but they all had one thing in common: performance as a top priority. Below, we have listed the rides that have already appeared in the series, and each week, we will update with new car cameos. Chevrolet Corvette C4 The photo above somewhat epitomizes one of the themes of The Last Dance. Everybody, whether that was men, women, children, franchise owners, reporters, coaches, teammates, or opponents, wanted a piece of Jordan. If that meant stopping in the middle of the road to get an autograph, then so be it. Around town, MJ was fairly easy to spot due to his flashy cars that occasionally wore Bulls red. Jordan has driven numerous Corvettes throughout the years, but the C4 is unique in that it was Chevy's top ride when Jordan signed an endorsement deal with the American company during his rookie year in 1984. Two famous photos, one in front of the Chicago skyline, show him standing next to a C4 with the license plate "Jump 23." This exact car, however, came later, as indicated by the squared-off taillights. He went on to star in a number of Chevrolet commercials with vehicles such as the Blazer and S-10 pickup truck. Chevrolet Corvette C5 The most notable Corvette His Airness ever owned was likely the C4 40th Anniversary ZR-1, but he also drove a C5 coupe at one point. Roughly nine minutes into the first episode, Jordan is seen driving the chrome-wheeled targa top into the parking lot at the Berto Center, the Bulls old practice facility.   Ferrari 550 Maranello Roughly three minutes into episode four, viewers get a glimpse of Jordan's exotic taste in the form of a red Ferrari 550 Maranello.
