Nissan Leaf keeps plug-in vehicle sales crown for 6th straight month

And Nissan makes it 14 in a row. For the 14th straight month, the all-electric Leaf has had "record sales," according to Nissan's marketing team. What that means is that for that particular month (in this case, April) no matter what year you look at, the car sold more than it ever did before. For April 2014, the 2,088 Leafs sold represents a 7.8-percent increase from 2013. Nissan's director of EV sales and marketing, Toby Perry, said in a statement that the "new market" of Cincinnati made the top 25 list for Leaf sales areas in April, so the car's popularity continues to ebb and flow across the US. Over at Chevy, the Volt sold 1,548 units in April, reaching a year-to-date total of 5,154. The Leaf is outpacing that with 7,272 YTD sales. In 2013, the Volt outsold the Leaf by about 500 vehicles, but Leaf sales are up 33 percent year-over-year while Volt is down 7.1 percent. The Leaf has also outsold the Volt for six straight months. But we're excited for every eco-car sale, and that's why we'll have our monthly detailed write-up of the rest of the plug-ins, hybrids and diesel vehicles available soon. Until then, discuss.

Chevrolet Silverado, GMC Sierra could get independent rear suspension

The Chevrolet Silverado and the GMC Sierra could reportedly receive a variant of the four-link independent rear suspension found under the new Tahoe and Suburban. While that's not a surprise, a recent report suggests electrification, not comfort, convinced General Motors to make the change. Replacing the time-tested solid rear axle with an independent suspension will improve comfort, handling and off-road prowess, while adding weight, and likely making the trucks a little bit more expensive. It's a fair trade-off, but GM Authority learned the real reason for the swap is that at least one of the pickups will spawn an electric model, and it's more difficult to package a bulky battery pack around a solid rear axle. The independent rear suspension takes up far less space, even if it has more moving parts. General Motors will build its first regular-production electric pickup on an evolution of the Silverado's T1 platform named BT1, according to the same source. The b stands for -- you guessed it -- batteries. The firm reportedly doesn't want to make two suspensions for cost reasons, so the independent setup will come standard regardless of whether the truck runs on gasoline, diesel, or electricity. As a bonus, Chevrolet and GMC could choose to offer their T1-based trucks with Magnetic Ride Control or an air suspension, options available on the 2021 Suburban and Tahoe. The independent rear suspension will also find its way to the next-generation GMC Yukon due to be revealed January 14, and to the 2021 Cadillac Escalade scheduled to make its debut February 4. The long-rumored, born-again Hummer will get it, too, because it will arrive as an electric model built on the BT1 platform. It's worth noting none of this is official, and General Motors has remained quiet about what's next for its new suspension design, and what will be under its electric truck's sheet metal. If the GM Authority report is accurate, the Silverado (pictured) and the Sierra could ditch their solid rear axle for the 2021 model year. The change will likely be accompanied by other tweaks inside and out. Featured Gallery 2019 Chevrolet Silverado 1500 View 16 Photos Chevrolet GMC Truck

Chevy Corvette is latest car breached by hackers

UPDATE: This story has been updated with comment from General Motors. In the latest car-hacking exploit in a summer full of them, researchers from the University of California-San Diego say they've found a way to manipulate braking in a 2013 Chevrolet Corvette. The vulnerabilities may not be limited to that model. Cyber-security researchers breached the car's security systems via a device they had plugged into the Corvette's OBD-II port, and through that connection, they sent messages that could turn windshield wipers on and off and tamper with the brakes as the car drove at low speeds. It's the latest in a series of car hacks that involve access to critical systems obtained via the OBD-II port, where drivers can plug in devices that provide anything from diagnostic information for mechanics to driving information for insurance companies. Last November, cyber-security engineers from Argus Cyber Security remotely controlled vehicle functions in a car that had a OBD-II dongle called a Zubie installed. In January, researchers from Digital Bond Labs found security holes in an information-tracking dongle popular with more than 2 million Progressive Insurance customers. Those came before prominent hacks unveiled in recent weeks, in which researchers remotely commandeered control of a Jeep Cherokee and, separately, showcased problems with GM's OnStar infotainment system. Regarding the dongles that plug into the OBD-II ports, Stefan Savage, a Cal-San Diego professor involved in the research, tells WIRED that, "we acquired some of these things, reverse-engineered them, and along the way, found that they had a whole bunch of security deficiencies." Savage and others unveiled the latest study at the Usenix security conference Tuesday. In a video of their exploit entitled "Fast and Vulnerable," they show how they sent SMS messages from a smartphone to the dongle plugged into the car's OBD-II port. From there, their messages accessed the CAN bus, a network on the car that connects individual electronic control units, which control dozens of vehicle functions. As they send the commands to brake the car, the driver of the Corvette notes "the pedal doesn't react to any pressure." General Motors issued a written response Wednesday, warning drivers to be careful with third-party devices they plug into their OBD-II ports.
