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.

2016 Chevrolet Camaro design teased

Chevrolet just can't seem to help itself from continuing to tease the next-gen Camaro. The pony car gets its official debut at a big event on Detroit's Belle Isle on May 16, but the upcoming model's new exhaust, suspension components, and wheels are already well known. With this latest taste, we're finally getting an official glimpse at what the coupe actually looks like. The 2016 Camaro's shape hasn't completely been a secret, and even Chevy showed it testing while covered in camouflage in March. Still, these shots are a great opportunity to check out some undisguised details for the new model. The styling is supposed to be "more athletic," according to Chevy, and the aluminum hood looks especially good with crisp, straight lines forming the design. "It's a more expressive evolution of the Camaro's iconic character – and one that complements its leaner size and sharper reflexes," GM global design boss Ed Welburn said in a statement. These two photos suggest a more angular, futuristic shape for the upcoming pony car. We're looking forward to seeing it all in a couple weeks. Sculpted Exterior Reflects 2016 Camaro's New Athleticism 2015-04-30 DETROIT – For the all-new 2016 Chevrolet Camaro, the design team set out to create a leaner, more athletic design that complemented the new driving experience. "The Camaro went to the gym and came out with a lithe, more athletic physique for the sixth generation," said Ed Welburn, vice president, GM Global Design. "It's a more expressive evolution of the Camaro's iconic character – and one that complements its leaner size and sharper reflexes." The exterior design vocabulary is defined by complex shapes, which appear to be form-fitted around the mechanical components. Every shape and surface detail is a skilled, artistic collaboration of hand and digital sculpting. Camaro's new design details draw the eye into the design. For example, the new aluminum hood features powerful, smoothly curved sculpted forms accented with sharp creases. As a result, the hood appears to be shrink-wrapped around the engine. Similarly, the new Camaro retains the broad, dramatic rear fenders that became a defining feature of the award-winning Gen 5 Camaro. The design is updated with greater detailing, including a subtle crease running parallel to the fender edge. The effect makes the new Camaro look even lower and wider despite having a slightly smaller footprint than its predecessor.

GM will recall 3.5 million pickups and SUVs to fix brake issue

WASHINGTON — General Motors Co is recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and increase the risk of a crash. The recall, which covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles, was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted Wednesday. NHTSA opened a preliminary investigation into the issue in November 2018, and said it had reports of 9 crashes and two injuries related to the issue. It provided GM in July with additional field reports that prompted the automaker to open an investigation. The company did not immediately say on Wednesday how many injuries or crashes are linked to the issue but said it could impact braking in "rare circumstances." GM said dealers will reprogram the Electronic Brake Control Module with a new calibration that will improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Recalls Chevrolet GM GMC
