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 recalling 2013 Buick LaCrosse, Cadillac SRX over transmission software

The National Highway Traffic Safety Administration has issued recalls for the 2013 Buick LaCrosse and 2013 Cadillac SRX due to a problem with the software for the transmission controller. On about 27,000 SRX and LaCrosse models, the transmission could accidentally be shifted to Sport mode, which would reduce the amount of engine braking drivers experience.
NHTSA says this could increase the risk of a crash, but, fortunately, the required fix is simply an update to the software.
While we're on the subject of General Motors vehicle recalls, a small number (48) of compressed natural gas versions of the 2011 Chevrolet Express are also being recalled for a potential risk of fire or explosion. Yikes. Both official recall notices are posted below.

2021 Cadillac Escalade makes its grand debut among the stars during Oscars week

The 2021 Cadillac Escalade has arrived in high style in Los Angeles during Oscars week. With no January Detroit Auto Show, there’s no better place for the next generation of CadillacÂ’s iconic luxury SUV to be revealed than star-studded L.A. We got to spend some time in and around the Escalade a couple weeks ago, and now we can finally tell you all about it. As expected, the 2021 Escalade is following in the footsteps of all the other full-size GM SUVs by going with an independent rear suspension setup. Just like the Tahoe and Yukon, Cadillac is also making the next-gen magnetic shocks and new air suspension optional equipment. Engineers told us that thereÂ’s hardly any difference underneath the Escalade versus its platform stablemates, and our early impressions of the ride suggest thatÂ’s perfectly fine. Powering the new Escalade is GMÂ’s trusty 6.2-liter V8 or the 3.0-liter turbo-diesel inline-six — both are paired with a 10-speed automatic transmission.   Related: 2021 Cadillac Escalade vs. 2020 Lincoln Navigator | How they compare on paper 2021 Cadillac Escalade ESV will debut at the New York Auto Show   WeÂ’re not surprised to see the oil-burner being offered as an option with the Escalade after itÂ’s been tucked under the hood of the Tahoe and Yukon, but it is a significant addition to the Escalade lineup. GM has never fit a diesel engine to an Escalade before, but engineers tell us that this motor is refined enough for an Escalade buyer. We were surprised by its smoothness in the Silverado, and weÂ’ll wager itÂ’s even more discrete in the luxury SUV. The lovely 4.2-liter twin-turbo V8 Blackwing engine was never mentioned in CadillacÂ’s presentation to us. We asked, but thereÂ’s no news to be had on the Blackwing front, as Cadillac shrugged us off. Arguably, the most important aspect of the new Escalade is its interior. When the redesigned Lincoln Navigator came out, it made the aging Escalade look like a boring dinosaur. Cadillac knew this interior had to be extraordinary to compete, and itÂ’s taken an interesting approach.  Do you recall the Cadillac Escala concept? If so, thatÂ’s exactly what Cadillac has done with the EscaladeÂ’s interior. The tri-screen layout of the EscalaÂ’s concept dash has been translated into a final production design, and it looks spectacular in person.
