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.

Sunday Drive: Taking a gaze into the automotive crystal ball

Mankind has long been fascinated by the future. So it makes sense that this past week's top stories were all about cars, trucks, and SUVs that won't be hitting the market until the 2019 model year. And right at the top of the list is the Ram 1500. We've come to know Ram as the truck maker that styles its pickups with cues cribbed from big rigs, but that look has slowly evolved over time into something uniquely its own. The next Ram 1500 continues this trend, with a newly refined look that we can't wait to see in person. Up next is the 2019 Chevy Silverado. Pickup trucks have been, continue to be, and will remain the best-selling vehicles in America. And General Motors is a leader in the field, with two distinct offerings with which to entice buyers, one from the bread-and-butter Chevrolet brand and one wearing the slightly more upscale GMC badge. The Chevy looks to get LED lighting elements for 2019, which ought to keep the truck from looking dated when compared to the Ford F-150 and the previously mentioned Ram 1500. From there we move past pickup trucks and into SUVs and sedans. The 2019 Jeep Cherokee looks to get toned down a bit with its next refresh, and the '19 BMW 3 Series continues its slow evolutionary journey at the top of its aspirational sales pedestal. Finally, spy shots give way to official production reveals for the 2019 Audi A7 and Polestar 1. This pair of European luxury cars won't compete with one another – one is a rakish hatchback and the other a sports coupe – any further than for the eyeballs of our readers, but both proved popular enough to merit inclusion in our weekly roundup. As always, tune in to Autoblog next week for a front-row seat to all the happenings worth following in the automotive industry. 2019 Ram 1500 spotted without the classic crosshairs 2019 Chevy Silverado spied with new LED accents 2019 Jeep Cherokee reveals a much more normal face 2019 BMW 3 Series spy shots reveal production lights, new interior details 2019 Audi A7 revealed: More torque, refined styling Polestar 1 First Look | The 600 horsepower hybrid Scandinavian Green Audi BMW Chevrolet Jeep RAM Volvo Truck Hatchback SUV Future Vehicles Hybrid Luxury Performance Sedan sunday drive polestar 1

Should heavy-duty pickup trucks have window stickers with fuel mileage estimates?

If you were to stroll into your nearest Chevrolet, Ford, GMC, Nissan, or Ram dealership, you'd find a bunch of pickup trucks. Most of those would have proper window stickers labeled with things like base prices, options prices, location of manufacture, and, crucially, fuel economy estimates. But you'd also run across a number of heavy-duty trucks with no such fuel mileage data from the Environmental Protection Agency. The EPA doesn't require automakers to publish the valuable miles-per-gallon measurement for vehicles with gross weight ratings that exceed 8,500 pounds. That makes it difficult for consumers to compare behemoths powered by turbocharged diesel engines – between one another, and between smaller, gasoline-fueled trucks. Consumer Reports doesn't think it should be this way, and it's spearheading an effort (PDF link) to get the government to require manufacturers to publish fuel economy estimates. In its own testing, CR found that heavy-duty pickups powered by Ford's Power Stroke, GM's Duramax, and FCA's Cummins diesel engines (which doesn't include the Ram's EcoDiesel) get worse fuel mileage than their lighter-duty gas-powered siblings. We're not so sure HD-truck buyers are unaware of this fact – big diesels don't really come into their own until big loads are placed in their beds or attached to their trailer hitches. Under heavy workloads, the diesel trucks will almost certainly return greater efficiency than a similar gas-powered truck. What's more, HD trucks with lumbering diesels in general make the driver feel more confident while towing due to greater torque at low engine RPM than gas trucks. They also offer greater max-weight limits. Still, we agree EPA fuel mileage estimates should be offered for heavy-duty pickups. And we think the comparisons provided by Consumer Reports might be interesting to potential buyers. Click here to see the results of CR's tests, and let us know what you think using the poll below.
