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.

The best Super Bowl car commercials from the last 5 years

If you've been dipping into the Autoblog feed over the past days and weeks, you wouldn't even have to be a sports fan to know the Super Bowl is coming up. Automakers have been teasing their spots for the big game, dropping them days early, fully-formed onto the Internet and otherwise trying to amp up the multi-million-dollar outlays that they've made for air time on the biggest advertising day of the year. And, we're into it. The lead up to the Super Bowl is almost akin to a mini auto show around these parts; with automakers being amongst the most prolific advertisers on these special Sundays. The crop of ads from 2015 looks as strong as ever, but we thought we'd take a quick look back at some of our favorite spots from the last five years. Take a look at our picks – created from a very informal polling of Autoblog editors and presented in no particular order – and then tell us about your recent faves, in Comments. Chrysler, Imported From Detroit Chrysler, Eminem and a lingering pan shot of "The Fist" – it doesn't get much more Motown than 2011's Imported From Detroit. With the weight of our staffers hailing from in and around The D, it's no wonder that our memories still favor this epic Super Bowl commercial (even though the car it was shilling was crap). Imported really set the tone for later Chrysler ads, too, repeated the formula: celebrity endorsement + dramatic copy + dash of jingoism = pulled car-guy heartstrings. Mercedes-Benz, Soul teaser with Kate Upton One of our favorite Super Bowl commercials (and yours, based on the insane number of views you logged) didn't even technically air during the game. Mercedes-Benz teased its eventual spot Soul with 90-seconds worth of Kate Upton threatening to do her best Joy Harmon impression. (Teaser indeed.) It doesn't win points for cleverness, use of music, acting, or any compelling carness, but it proved that Mercedes' advertisers knew how to make a splash in the Internet Age. And, hey, it's still classier than every GoDaddy commercial. Kia, A Dream Car. For Real Life Like the Mercedes video above, the initial draw here is a pretty lady; in this case the always stunning Adriana Lima. But this Kia commercial really delivers the extra effort we expect while scarfing crabby snacks and homemades, too. First of all, Motley Crue. Second, a cowboy on a bucking rhino. Enjoy yet again.

Next-gen Chevy Silverado and GMC Sierra may use carbon fiber

It's been generally accepted that the next generation of full-size GM trucks will use some sort of strong, lightweight material for the beds while retaining steel for the cab. While aluminum seems like the most obvious choice, according to Automotive News, the Chevy Silverado and GMC Sierra will incorporate both aluminum and carbon fiber in their beds. The publication cites sources from within GM, though it seems the introduction of this comparatively exotic material mix is still a few years off. While carbon fiber is both stronger and lighter than steel and aluminum, it takes significantly more time and money to produce, essentially relegating the material to small-volume cars. The main benefit for trucks is the resulting reduction in weight to improve fuel economy without sacrificing the tough, rugged capabilities truck buyers expect. The Ford F-150 made the switch to aluminum for the 2015 model year and it's proved highly successful. It seemed like it was only a matter of time before the competition followed suit. Automotive News says that the next-gen trucks will launch with aluminum beds and that it will take a couple of years before we'll see any carbon fiber incorporated into the design. Even then, only look for the composite material on higher-trim models, with a trickle down to lower-spec trucks possible further in the future. In 2011, GM announced it was working with Japan-based Teijin Limited on a carbon fiber reinforced thermoplastic. There's a good chance that material's introduction will be on trucks.
