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.

Cadillac CT6 to be lighter than CTS, get PHEV model

Cadillac is suddenly one of the most talked about automakers in the US with Johan de Nysschen taking control. The brand claims that it eventually wants to become, once again, the standard of the world. One of the first vehicles to actually prove whether that's possible is its upcoming CT6 flagship sedan. We still don't know what the production version looks like undisguised, but other important details are falling into place. The latest big news sheds some light on the Caddy's powertrain and some estimates of its weight and size.
General Motors product chief Mark Reuss dropped the details at the automaker's Global Business Conference. According to The Detroit News, he revealed that the CT6 would use a twin-turbocharged, 3.0-liter six-cylinder engine with an eight-speed automatic transmission, and a plug-in hybrid would be an additional option. He reportedly claimed it would be the most "powerful six-cylinder gas engine in the segment" and said the hybrid could get around 70 miles per gallon.
Reuss also revealed that the CT6 would be about 53 pounds lighter than the current CTS, despite being about 8 inches longer, according to The Detroit News. If that's the case, the new flagship is about 203.5-inches long, which is 1.5-inches more than the XTS.

Cadillac ELR update delayed over autonomous drive systems issues

Rumors had been circulating that the 2016 Cadillac ELR would bow in Los Angeles recently, featuring, in Cadillac's own words, "engineering enhancements." The rumors and that quote are as far as it got – the updated ELR pulled a no-show in LA, and no one outside of the brand appears to know when it will appear. GM Inside News says its sources at Cadillac pinned the ELR's absence on some autonomous driving features not being ready to reveal. According to GMI, Cadillac insiders say the upgraded ELR will be a "highly autonomous vehicle," and the company needs more time to gets its systems polished. The site says "it's not unreasonable to assume that ELR will be [the] vehicle" that gets Cadillac's Super Cruise technology, but that seems a lot more involved than "engineering enhancements," and in September Cadillac said we'd see it sometime in the next two years. It's possible the wait for the 2016 ELR and its secrets might only be a couple of months: the next-generation Chevrolet Volt, which shares a platform with the ELR and whose engineering updates we know quite a bit about, is scheduled to appear at the 2015 Detroit Auto Show in January.
