GM executive chief EV engineer says reducing cost of plug-in vehicles is 'huge priority'

As we know, another major automaker investing heavily in electrified vehicles is General Motors, and it's doing things much differently than rivals BMW, Ford or Nissan. The Chevrolet Volt extended-range EV is a modest seller at its $35,000 sticker price but a huge hit with owners. The Chevy Spark BEV, still in limited availability, puts smiley faces on its owners and drivers. The just-introduced Cadillac ELR, a sharp-looking, fun-driving $76,000 luxocoupe take on the Volt's EREV mechanicals, has admittedly low sales expectations. With this interesting trio in showrooms and much more in the works, the third vehicle electrification leader I collared for an interview at Detroit's North American International Auto Show (see #1 and #2) was Pam Fletcher, GM's executive chief engineer, Electrified Vehicles. ABG: Why do your EREVs need four-cylinder power to extend their range when BMW's i3 makes do with an optional 650 cc two-banger? "We designed [the Volt and the ELR] to go anywhere, any time" - Pam Fletcher PF: I get that question all the time: why not something smaller? You don't really need that much. You use the electric to its ability, then you just need to limp. But we designed those cars to go anywhere, any time, and we don't want their performance to be compromised. If you're driving through the mountains, we don't want you to be crawling up grades, or to be limited on any terrain. So it's optimized to be able to travel literally the biggest grades and mountain roads around the globe at posted speeds. Because what if you can't? Another good reason: when the engine is on, you have to run it wide open throttle, max speed, most of the time. And while we can do a lot with acoustics, and the ELR has active noise cancelation, a small-displacement, low cylinder-count engine at high speed, high load all the time isn't something you want to live with. That's how we came up with the balance we did among the key factors of performance, NVH [noise, vibration and harshness] and range. ABG: Where you go from here? Is the range-extender engine due for an update? PF: We know and love the current Volt, and there is still a lot of acclaim about it, so we think it's a good recipe. But we are heavily in the midst of engineering the next-generation car, which I think everyone will love and be excited about.

2018 Autoblog Technology of the Year finalists

After months of prepping and several days of testing, we narrowed the field for Autoblog's 2018 Tech of the Year award to the Nissan Rogue with ProPilot Assist semi-autonomous driving system, the Lexus LC 500h and its new hybrid powertrain, and the Chevy Colorado ZR2 and its trick Multimatic spool-valve off-road shocks. Three very different cars with very different technologies duking it out for the award. Look for news of our winner at the 2018 Detroit Auto Show. We hand out this award every year to the technology or feature that we feel moves the bar forward for the automotive industry. Read more here on how our testing process works. We discuss, debate and count up score sheets, judging each vehicle and technology on a few different criteria. Is its purpose noteworthy? Does it work well? Does it advance the industry? The Nissan Rogue with ProPilot Assist was actually a prototype, as the technology will first debut in the 2018 Nissan Leaf. Still, we're here to test the tech and not the car. ProPilot Assist combines adaptive cruise control system combined with lane-keeping assistance. The system uses sonar, radar and a number of cameras for some light semi-autonomous driving and enhanced safety. While these systems aren't new individually, Nissan's system is affordable, intuitive, and coming to a mainstream product — democratizing the tech in a novel way, if you will. That's why it's here. The Lexus LC 500h uses a new powertrain that Lexus has dubbed the Multi-Stage Hybrid System. Basically it combines two types of transmissions — a CVT and a four-speed automatic — in a single unit mated to a naturally aspirated V6. That's complex and unorthodox technology, and Lexus engineered it to give drivers the efficiency of a CVT without sacrificing driving enjoyment. The package is subtle, working in the background to create a nearly seamless driving experience. It's engaging in a way most other hybrids can only dream of. The fact that it's wrapped in such gorgeous sheetmetal only makes things better. The Multimatic spool valve shocks in the Chevy Colorado ZR2 might seem low-tech compared to ProPilot Assist and the Lexus Multi-Stage Hybrid, but they represent a completely novel application of a technology that several years ago was so expensive that it was reserved for top-tier race cars. Like the LC 500h, these shocks really change your perception of how a vehicle like this should drive.

Chevy Colorado gets Midnight, Trail Boss editions

After introducing a gamut of special editions for the full-size Silverado, Chevrolet is offering a pair of new packages for its midsize Colorado. Following in the Silverado's footsteps, the Colorado Midnight Edition just blacks out all the things. There's a black grille, black Bowtie, and exclusive 18-inch wheels. They happen to be black, as well. In terms of functional changes, the Midnight Edition adds a spray-in bedliner, tonneau cover, and unique sill plates. Potential owners won't be limited on engine options and body styles here, as the blacked-out trim can be added to extended and crew cab bodies, in two- or four-wheel drive models, and with all of the pickup's available engines, including the upcoming Duramax diesel. The only limiting factor is the actual trim level – you'll need to settle for the mid-grade LT. Don't worry, though. The heftier, top-of-the-line Z71 will be offered with its own unique package, called the Trail Boss. As expected, it goes big on off-road character, with LED trail lighting and aggressive Goodyear Wrangler DuraTec tires. There are also black 17-inch wheels, newly flared fenders, side steps, and like the Midnight Edition, a blacked-out grille and spray-in bedliner. Also like the Midnight Edition, the only limit to adding the Trail Boss is that you opt for the Z71 trim. Engines, drivetrains, and body styles are not fixed. Look for both trucks at your local Chevrolet dealer this fall. Until then, scroll down for the official press release. 2016 Chevy Colorado Special Models Dressed to Impress Midnight Edition, Z71 Trail Boss complement capability with customized style 2015-08-03 DETROIT – On the street or on the trail, the 2016 Chevrolet Colorado's Midnight Edition and Z71 Trail Boss bring bolder choices to customers looking to make a visual statement with their truck. The special editions roll into Chevrolet dealerships this fall, with distinctly tailored appearances that blend custom design cues with Colorado's popular options and accessories. The Midnight Edition evokes the aesthetic of an urban tuner vehicle, while the Z71 Trail Boss is designed for terrain where the pavement ends. "These are aggressive editions of one of the country's hottest-selling truck, demonstrating the personalization that's possible with Chevrolet accessories, whether it's for the street, trail or both," said Tony Johnson, Colorado marketing manager.
