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.

GM to make most cars LTE hotspots for 2015

General Motors isn't the first automaker to deliver in-car Internet access, but a proposed plan announced today could make the technology more widespread than any of its competitors have offered. By the 2015 model year, most Chevrolet, Buick, Cadillac and GMC products in the US and Canada will offer 4G LTE mobile broadband access. Initially, GM will just be pairing with AT&T to deliver this service, but additional carriers will be revealed in the future.
Current in-car Wi-Fi hot spots are limited to 3G, but GM says that 4G LTE is 10 times faster than 3G service and will allow for full Internet access, including streaming video for entertainment as well as services like real-time traffic updates and navigation driving directions. There is also no need for a paired smartphone with this new system, which should make it easier to use, and GM and AT&T will also be working together to develop new apps for customers.
Buyers can expect to start seeing 4G LTE in their cars starting next year, and GM is already planning to expand the service to other global markets as well. All of the information from GM's announcement is posted in a press release below.

Semi-autonomous Cadillac CT6 has Batman's seal of approval

Earlier this year, Cadillac pushed the launch of its Super Cruise semi-autonomous technology back to 2017, but it looks like the automaker is still hard at work testing the system on its vehicles. Our photographers snapped a CT6 sedan with what appears to be the Super Cruise technology in broad daylight. The CT6 in the pictures, ignoring the massive equipment on the car's roof, appears to be stock. The barely camouflaged vehicle has more sensors on the front fascia and a black rear bumper, but other than those points, looks normal. Getting back to the massive piece of equipment on the CT6's roof. There's no way to definitively state what it is, but there appears to be four cameras on the corners of the rack. A sensor or camera is also fitted to the right side mirror, which is slightly camouflaged. With all of the wires from the roof going into the vehicle, there's a chance that the massive blacked-out piece of equipment on the roof could be used to gather data. While the equipment looks extremely scientific, someone at Cadillac must have a sense of humor, or be a huge fan of DC Comics, as a Batman's logo is prominently displayed on the roof-mounted gear. Cadillac announced its Super Cruise semi-autonomous technology two years ago. The system will be able to speed the car up, keep the vehicle in its lane, and slow it down. The goal, in 2014, was to introduce the technology in two years (2016), but the automaker delayed the tech until 2017.
