General Motors and EVs: No stranger to firsts, but where's the leadership?

2015 is already shaping up to be the year of "affordable, 200-mile EV" concepts. Nissan and Tesla have each been talking about them for some time, the latter promising to unveil its Model 3 at the North American International Auto Show in January before balking when the time came. Instead, Chevrolet beat them all by unveiling the Bolt concept at the same event, followed shortly thereafter with suggestions of a 2016 launch – potentially offering the first nationwide EV with anything close to that range. It was the ballsiest EV-related move General Motors has made in a quarter century. But will it remain so? Exactly 25 years before the Bolt rolled up onto the turntable, then-Chairman Roger Smith unveiled GM's last ground-up EV concept, the even-more-unfortunately-named Impact, at the Los Angeles Auto Show in January 1990. A few months later, he surprised most of his colleagues by announcing its intended production in honor of Earth Day. It was the first modern foray into electric vehicles for the US by any automaker, one that was rewarded by the State of California with what is now known as the Zero Emissions Vehicle mandate. The program not only forced other automakers into competing with Roger's pet project, but inspired all of them to fight it like small children against bedtime. Some years later, the drivers themselves weighed in, with a biting documentary about that obstinance and the leadership it cost both GM and the country. Within months, GM was first back into the fray of plug-in vehicles. Many criticized the company for starting with a PHEV rather than jump straight back into EVs. The choice wasn't totally out of the blue – even EV1 was meant to be followed by a PHEV. And especially on the heels of Who Killed the Electric Car?, some skittishness was understandable: even a successful EV would invite a "we told you so" public reaction, underscoring their mistake in ending the EV1 program. If a new EV didn't do well, they'd be convicted in the public eye as serial killers. All while seeking a federal bailout. For all the flak, the resulting Chevy Volt was and is a better car than GM has ever gotten credit for. But the company seemed to grow weary of having to overcome its varied past, and while the current owners remain happy, much of the stakeholder and community engagement that so effectively built early goodwill and sales growth faded not long after launch. Marketing has been spotty in both consistency and effectiveness.

2016 Chevrolet Spark lights up New York

The little Spark has been somewhat of a surprising entry in the modern Chevy lineup in the US. Given its diminutive stature, you might have expected the slightly larger Sonic to cannibalize the tiny sibling's sales, but that hasn't happened. The Bowtie moved 39,159 Sparks in the US in 2014, a 14.7 percent boost from the previous year. Now at the 2015 New York Auto Show, the latest generation is being unveiled with a new engine and much improved styling. Replacing the current 1.2-liter four-cylinder is an all-aluminum 1.4-liter unit making 98 horsepower. That still doesn't sound like much, but it's 16 percent more than the 2015 Spark. The new mill can be connected to either a five-speed manual or a continuously variable transmission with which Chevy estimates 40 miles per gallon highway fuel economy. The 2016 Spark also gets a longer wheelbase and 1.6-inch lower overall height. Combined with more elliptical headlights at the front, the changes make for a somewhat more sleek appearance than the current, boxy model. The platform underneath is more rigid as well, and Chevy claims the latest underpinnings mean better handling and lower NHV levels inside. The little hatch isn't growing up too much, though, and gets a trio of new colors that sound like jellybean flavors: Toasted Marshmallow, Kalamata and Splash. Chevy is packing the interior with better quality materials and improved tech. Chevy's latest seven-inch MyLink system sits in the center stack with a capacitive touchscreen, and it now comes with a physical volume control and other buttons for easier use. All models also get a rearview camera, and a LCD instrument cluster remains in front of the driver. The available suite of safety systems includes Forward Collision Alert, Lane Departure Warning and Side Blind Spot Alert. The 2016 Spark goes on sale in the US in the fourth quarter of 2015 and is produced in South Korea. Expect a gallery showing off all its new styling from the New York show floor soon.

Why an independent rear suspension for GM's new, full-sized SUVs wasn't easy

A Motor Trend report last month laid out how Cadillac's 4.2-lier twin-turbo Blackwing V8 could be an orphan due to cost concerns in the GM empire. Last-minute chassis changes to Cadillac's new sedans and XT6 crossover led to engine bays that couldn't fit the Blackwing. On the SUV side, according to the report, the new independent rear suspension for big people haulers cost so much to implement that GM ruled out reworking the Escalade to accept the Blackwing. At least one commenter rightly asked how could a suspension swallow that much money. A new piece in Motor Trend has the answer. The excellent Alissa Priddle spoke to Tim Herrick, GM's executive chief engineer for full-size trucks, about why the clean-sheet IRS cost "multimillions of dollars."  First, GM would need to build a new body shop at the Arlington, Texas plant that assembles the automaker's big SUVs to stamp the numerous wholly new parts and panels accommodating an IRS. Then GM would need to design and pay for a new assembly process. On top of those up-front costs, there was the incremental cost of the four-link IRS components being more expensive than those in the trucks' former leaf-sprung solid axles. Herrick endured so many rejections for so long that he remembers the date and time when he got approval for the new unit. He said it came down to a meeting where he told a higher-up, "I'll make you a deal: If we get to the reveal, or if we launch this and you think this was a dumb idea, I'll hand you my badge and let you walk me out." Head to Motor Trend to read the full story. Based on Herrick being on stage to help present the new SUVs to the press, and on our First Ride in the new Chevrolet Tahoe and Suburban at GM's Milford Proving Grounds, it appears this will have a happy ending for all involved. Furthermore, since Herrick worked on the T1 platform that supports the big SUVs as well as the light- and heavy-duty pickups, he understood the demands on the commercial side, too. That could be why when Roadshow asked Tim Asoklis, chief engineer of the Tahoe and Suburban, if the new IRS could endure life in the Chevrolet Silverado and GMC Sierra, Asoklis answered, "Oh, absolutely."
