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

Best car infotainment systems: From UConnect to MBUX, these are our favorites

Declaring one infotainment system the best over any other is an inherently subjective matter. You can look at quantitative testing for things like input response time and various screen load times, but ask a room full of people that have tried all car infotainment systems what their favorite is, and you’re likely to get a lot of different responses. For the most part, the various infotainment systems available all share a similar purpose. They aim to help the driver get where they're going with navigation, play their favorite tunes via all sorts of media playback options and allow folks to stay connected with others via phone connectivity. Of course, most go way beyond the basics these days and offer features like streaming services, in-car performance data and much more. Unique features are aplenty when you start diving through menus, but how they go about their most important tasks vary widely. Some of our editors prefer systems that are exclusively touch-based and chock full of boundary-pushing features. Others may prefer a back-to-basics non-touch system that is navigable via a scroll wheel. You can compare it to the phone operating system wars. Just like some prefer Android phones over iPhones, we all have our own opinions for what makes up the best infotainment interface. All that said, our combined experience tells us that a number of infotainment systems are at least better than the rest. WeÂ’ve narrowed it down to five total systems in their own subcategories that stand out to us. Read on below to see our picks, and feel free to make your own arguments in the comments. Best infotainment overall: UConnect 5, various Stellantis products Ram 1500 Uconnect Infotainment System Review If thereÂ’s one infotainment system that all of us agree is excellent, itÂ’s UConnect. It has numerous qualities that make it great, but above all else, UConnect is simple and straightforward to use. Ease of operation is one of the most (if not the single most) vital parts of any infotainment system interface. If youÂ’re expected to be able to tap away on a touchscreen while driving and still pay attention to the road, a complex infotainment system is going to remove your attention from the number one task at hand: driving. UConnect uses a simple interface that puts all of your key functions in a clearly-represented row on the bottom of the screen. Tap any of them, and it instantly pulls up that menu.

Nissan Leaf sales double Chevy Volt to close out winning 2014

To close out the year, sales of the two most-popular plug-in vehicles in the US kept going in the direction that they had been all year. The Chevy Volt dropped and the Nissan Leaf had another record month. Sound familiar? The Volt sold 1,490 units in December, a year-to-year drop of 37.7 percent. For all of 2014, Volt sales were down 18.6 percent to just 18,805 (from 23,094 in 2013). On the Nissan side of the ledger, the Leaf sold 3,102 units, up 22.7 percent from the 2,529 sold in December 2013. For the year, Nissan sold 30,200 Leafs, up 33.6 percent from the 22,610 sold in 2013. A few other things to note: For every month in 2014, the Leaf sold more than it did for the same month in 2013. For the Volt, this was only true for three months (April, May and July). Funnily enough, the Volt sold exactly 1,478 units in both March 2013 and 2014. The Volt's 2014 total was lower than both 2013 and 2012, while the Leaf had its best year ever. There were three months in 2014 when people bought at least twice as many Leafs than bought a Volt (September, November, December). The Leaf outsold the Volt every month in 2014. The closest gap was 215 units, in February. The biggest was 1,612, in December. As you've most likely seen, GM is still busy teasing the new Volt, which will make its official debut at the Detroit Auto Show next week. We'll have a more in-depth green car sales post up soon. <iframe embedded="true" "="" scrolling="no" src="https://docs.google.com/spreadsheets/d/1oIuH75vaSHaaplD4x6gLsYjSsiN4oGmez1T63eaYdhY/pubhtml?widget=true&headers=false" height="430"> Nissan celebrates 30,000 leaf sales in 2014, best year ever for sales of any plug-in vehicle NASHVILLE, Tenn. (Jan. 5, 2015) – Nissan, the world leader in electric vehicle sales, shattered yet another sales record with 30,200 LEAF vehicles sold in 2014, which is the first time any plug-in has sold more than 30,000 units in a single year. "Now in its fifth model year, Nissan LEAF is more popular than ever and continues to bring new buyers to Nissan," said Brendan Jones, director, Nissan Electric Vehicle Sales and Infrastructure. "From the beginning our vision was to bring electric vehicles to the mass market in a practical and fun-to-drive package, which is what makes Nissan LEAF the best-selling electric car in the world." Last month, Nissan sold 3,102 all-electric LEAFs, up 22.7 percent from the prior year and a December record.
