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

Motor Trend puts Chevy Camaro Z28 and Porsche 911 GT3 Head 2 Head

Motor Trend admits, "This is an unfair comparison." But that doesn't make it any less fun to watch when they pit a Camaro Z/28 against the Porsche 911 GT3. The former has a 7.0-liter V8 with 505 horsepower and 481 pound-feet of torque shifted through a six-speed manual. The latter has a 3.8-liter flat-six with 475 hp and 324 lb-ft shifted through a seven-speed dual-clutch transmission. Yet those are only the little disparities – the big disparities are mass and money: the Camaro weighs 3,882 pounds and costs $76,150 as-tested, the Porsche weighs 3,267 pounds and costs $145,785. But they're both about hardcore performance, so MT takes them out on the street, to the drag strip, to the parking lot for figure eights and a skidpad test, and finally to Big Willow for Randy Pobst to give his professional assessment. Remember when a lotta people spent a lotta time debating Pirates vs. Ninjas? This is like that, only it's the "haul-ass good-time car" vs. the "track surgeon." Enjoy the debate in the video.

See all seven colors available on 2016 Chevy Volt

General Motors has been happy to promote the 2016 Chevy Volt in the shiny blue color. On the company's website for the car, though, we can find all seven exterior colors, thanks to the magic of digital technology. We went through the site and played around with the option picker and put together a gallery of all the colors the new Volt will be available in as well as the five interior options. For the record, the exterior colors are: Kinetic Blue Metallic, Iridescent Pearl Tricoat, Summit White, Silver Ice Metallic, Mosaic Black Metallic, Siren Red Tintcoat, Heather Grey Metallic. You'll be forgiven if you can't quite tell the difference between the Pearl and the White in these images, but both colors have been available on the 2015 model year Volt. GM spokesperson Michelle Malcho told AutoblogGreen that buyers do have a preference, with Pearl accounting for 10 percent of the sales and Summit White accounted for 17 percent. The Pearl color is a tri-coat and thus has a $995 price premium, which was likely a factor as well. The interior of the new Volt will have two cloth options (Dark Ash and Jet Black) and three leather choices (Dark Ash, Jet Black, and Jet Black/Brandy). That last one will only be available in the LTZ trim level. You can play around with the color adjuster yourself here. Kathy Sirvio, the color and design manager of the Volt design team, told AutoblogGreen that, "Kinetic Blue is a marketing name. At Design we call it 'Blew Me Away'. That is it in a nutshell. The blue color is vibrant, rich and eye catching. It may not sell at the highest volume, as we know from history whites, blacks and silvers are the dominant color sales. However, it will tell everyone who sees it on the street that here comes a new vehicle and it is expressive in all the right ways." The next-gen Volt arrives later this year with a starting price of $33,995. The powertrain upgrades will push the all-electric range to 50 miles and the gas-only fuel economy to 41 miles per gallon.
