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

Recharge Wrap-up: Phoenix Cars delivers ZEUS to Navy, Volt saves gas compared to i-MiEV

Phoenix Cars has delivered its first Zero Emissions Utility Shuttle (ZEUS) flatbed truck to the US Navy. The electric flatbed will be used to transport maintenance materials around Naval Base Ventura County Port Hueneme. The Phoenix ZEUS features a 100-mile range, and can charge in just three hours. It also features vehicle-to-grid technology and direct power capability, allowing it to function as a mobile power station. ZEUS customers enjoy an eight-year/300,000-mile battery warranty and round-the-clock technical support from Phoenix. Phoenix launched an electric passenger shuttle last year, and years ago worked on an electric sport utility truck before shifting over to larger vehicles. Read more in the press release from Phoenix Cars. A man found that he used less gas by trading in his Mitsubishi i-MiEV for a Chevrolet Volt. Ben Rich saved fuel in part by using his Volt for road trips rather than needing to rent cars. Rich also found other benefits to driving a Volt, including more comfort, more freedom of movement and less range anxiety. Rich often had to turn off the heat in the winter to eke out precious miles in the Mitsubishi, which he needn't do in the Chevy, though he did have a gripe about the Volt using the gas motor to warm the car.

ChargePoint has tallied over 9 million charging sessions for a total of 65 gigawatt hours of energy. Based on national efficiency averages of three miles per kWh and 23.9 miles per gallon, this has saved 8.2 million gallons of gasoline and 60 million pounds of CO2. This accounts for what ChargePoint calls a "huge environmental impact." Read more in the release from ChargePoint below. The Environmental Impact of ChargePoint Drivers Campbell, Calif.– We all know electric vehicles (EV) have enormous environmental advantages over gas vehicles. Plug-in EVs reduce carbon-based greenhouse gases, improve air quality and reduce our dependence on fossil fuels. EV drivers on the ChargePoint network have had a huge environmental impact. With over 9 million charging sessions delivering 65 gigawatt hours of energy, EV drivers have avoided over 60 million pounds of CO2 and 8.2 million gallons of gasoline, and driven over 196 million gas-free miles. *Based on national averages: EV efficiency of 3 miles per kWh, gas efficiency of 23.9 mpg and a net savings of 0.924 pounds of CO2 per kWh.

GM says hybrid Corvette no laughing matter [w/poll]

When Mark Reuss was in LA recently, he sat down to have a few words with the scribes at the Los Angeles Times. When the issue of a hybrid Corvette came up, Reuss answered with "Don't laugh." The General Motors president is a complete fan of the possibility, calling it "attractive" and "really fun," believing it would improve GM expertise and that "people would love it."
Naturally, the president being supportive of an idea doesn't give indication that a hybrid Corvette is on the way. However, with supercars like the Porsche 918 Spyder and Ferrari LaFerrari giving hybrid tech a solid, if remote, place in the performance car world, the inexorable trickle-down of technology means we shouldn't be surprised if and when it does happen.
And now that we have that non-negative half-answer to a speculative question, it would be irresponsible for us not to commence rumormilling for the C8 Corvette. Taking Reuss at his word, the C8 will obviously be a hybrid with all-wheel-drive - the left side wheels driven with electric motors, the right side with the mid-mounted, four-cylinder diesel engine. With coefficient of drag of just .16, figure on a 0-to-60 mile-per-hour time of under 2 seconds and an all-electric range of something like 30 miles at top speed. Don't forget, folks, you read it here first.
