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.

Want to beat LA traffic? Chargers QB Philip Rivers has found a way

Slogging through traffic in Southern California is about as pleasurable as being slowly eaten by bears or being the awkward third wheel on a bad first date. It feels like it's never going to end. After the team relocated to Los Angeles from San Diego, Chargers quarterback Philip Rivers decided that three hours wasted each day in a car was too much. As The San Diego Union-Tribune reports, Rivers' rolling office makes his days more productive than ever. After deciding that he wasn't going to relocate his family to Orange County, Rivers was stuck with the prospect of either spending considerably less time with his children or skipping out on much-needed film work at the team's training facility (not really an option given his profession). Instead, he began investigating a number of options to make his lengthened commute slightly more viable and productive. First, he considered carpooling with a teammate. That was still too much of a pain. He looked at flying a helicopter, but unless it could land close to both his home and the practice field, it too was useless. A quick online search eventually led to the rolling footage review room you see here. Becker Automotive Design in Oxnard, Calif., builds these rolling offices for a wide range of customers. It sells modified Mercedes-Benz Sprinters, Ford Transits, and, in Rivers' case, a Cadillac Escalade with a raised roof. His needs were simple: a television and an HDMI input so he can hook up his computer. No fancy armor or recumbent exercise bicycle. His goal was to review game footage on his commute rather than slowly waste away behind the wheel of a car. Photos show a sea of leather and wood and a mini fridge, so it's not totally without niceties. Column | Philip Rivers' new ride allows him to stay home https://t.co/btwCEgIsFq pic.twitter.com/DHud3ho5UF — The Union-Tribune (@sdut) September 5, 2017 The Union-Tribune lists the price of the Escalade at about $200,000. That's not including the driver's salary. In 2015, Rivers signed a four-year deal with the Chargers worth $84 million, so he's not hurting for cash. If it increases productivity and saves the headache of being behind the wheel in traffic, we can imagine more people with means (and not just quarterbacks) will be opting for such daily transport.

GM Super Cruise beats Tesla Autopilot again in latest hands-free test

DETROIT — General Motors' Super Cruise once again edged Tesla's Autopilot in an evaluation of 17 vehicles equipped with active driving assistance systems (ADAS) by Consumer Reports, the testing organization said on Wednesday. A Tesla Model Y fitted with Autopilot finished "a distant second," the group said, to a Cadillac CT6 equipped with Super Cruise, which GM is rolling out to more than 20 vehicles — including its new Hummer electric pickup truck — over the next three years. Safety and insurance researchers have frequently warned of the risks of consumers overestimating ADAS systems' abilities, a misconception increased by some automakers calling their products Autopilot, ProPilot or Co-Pilot. In 2018, the Cadillac CT6 with Super Cruise scored higher than a Tesla Model 3 with Autopilot, in a Consumer Reports test of just four vehicles equipped with ADAS. In the latest test, conducted this summer on a track and on public roads, the Cadillac scored 69 points out of a possible 100, while the Tesla scored 57. A Lincoln Corsair equipped with Ford's Co-Pilot 360 system, finished third with 52. The critical difference in the Super Cruise system is a driver-facing infrared camera to make sure he or she is paying attention to the road and is ready to take over manual control when necessary, said Kelly Funkhouser, head of connected and automated vehicle testing at Consumer Reports. The group noted that Autopilot can shut off abruptly in some situations, while Super Cruise did a better job of notifying the driver when the system is disengaging. In recent European safety testing, a Tesla Model 3 with Autopilot placed sixth out of 10 systems, getting high marks for performance and ability to respond to emergencies, but falling short on its ability to maintain a driverÂ’s focus on the road.
