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.

Car and Driver 10Best list cracked by Tesla Model S, BMW 3 Series left off

Car and Driver is keeping new blood pumping into its annual 10Best cars list with three new entries making it on for 2015 and a perennial favorite falling off. Among the biggest shocks this year is that the BMW 3 Series and 4 Series are no longer named, despite years of some portion of that lineup earning a mention. In another surprise, the Tesla Model S (specifically in S 60 trim to fit under the $80,000 cost cap) makes it to the 2015 roster and is the only electrically motivated member of the group. Despite the loss of the 3 Series, BMW isn't entirely shut out this year, because the M235i gets its name on the list. Car and Driver argues that the little coupe feels like a welcome throwback to the E46 chassis M3 of the early 2000s. In addition to the Model S, the final newbie to the annual group is the 2015 Ford Mustang GT. The inclusion of these new members knocks the Audi A6/A7 family and Ford Fiesta ST out from the 2014 rundown. The other seven models carry over from last year, including the Cadillac CTS, Chevrolet Corvette Stingray, Honda Accord, Mazda3, Mazda6, Porsche Boxster/Cayman and Volkswagen Golf/GTI. The 2015 10Best cars list certainly seems to have something for everyone from the hot hatch fan to the family man and even the green car driver, thanks to the addition of the Tesla. Head over to Car and Driver to read its detailed explanations for each vehicle's inclusion, but if you've got a difference of opinion or just really like the list, let us know in Comments.

Hybrid, Plug-in Hybrid and EV Buyer's Guide: Which one do you want?

If you're shopping for a new vehicle these days, there's a litany of acronyms, buzzwords, and technobabble to further complicate an already difficult decision. But if you're looking at a green powertrain, you have three basic choices to compare: hybrid, plug-in hybrid and "EV" or, electric vehicle. So what are they and which one — if any — is right for you? Research your next new vehicle using Autoblog's Car Finder. Gasoline-Electric Hybrids By now, most people are familiar with the concept of a hybrid car. Thank Toyota's Prius for that. At its most basic, a hybrid vehicle has two powertrains, one gasoline and one electric, which work together for maximum efficiency. At low speeds, the engine can shut off entirely, relying solely on the battery for propulsion. The battery is either charged as you drive by converting kinetic energy into potential energy via a complex regenerative braking system, or directly off of the gas motor. This is a very hands-off, behind-the-scenes system as all the driver has to is put in gas and drive as normal. Hybrids come in all shapes and sizes and, according to the EPA, range in fuel economy from 58 mpg for the Hyundai Ioniq Blue all the way down to 13 mpg for the Ferrari LaFerrari Aperta. Best For: Anyone who want to see their fuel consumption go down without many sacrifices. You can easily find a hybrid sedan, hatchback, crossover, SUV or even a pickup truck (i f you can find one). Best of all, a hybrid requires no special equipment to be installed at home, or added work for the driver. Hybrids do cost more than traditionally-powered competitors, so make sure to compare projected fuel savings with how much extra a hybrid will cost – it may take a surprisingly long time to break even. The EPA provides a handy calculator for this very purpose. Our Favorite Hybrids: 2017 Toyota Prius 2018 Hyundai Ioniq Hybrid 2017 Ford Fusion Hybrid Plug-In Hybrids Sometimes referred to as a PHEV, or plug-in hybrid electric vehicle, this is a baby-step towards full electrification. Armed with a much larger battery pack than a hybrid, PHEVs can go between 12 ( Mercedes-Benz GLE550e) and 97 ( BMW i3 w/Range Extender) miles on electricity alone depending on the model and your driving style. Like a normal hybrid, the driver is largely unaware of which power source is currently in use, even as they switch over — either because the battery is drained, or the driving circumstances require more power.
