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.

Driving the 2016 Cadillac CTS-V at the old Elkhart Lake road course

The placid community around Elkart Lake, WI, looks about as far removed from a glorious motorsport venue as you can imagine. A turn of the century downtown gives way to old-school resorts, beaches, and boat launches around the picturesque lake, with farms framing the rolling hills all around. But it was those very same meandering country lanes that gave birth to one of America's greatest racing circuits, some 65 years ago. Between the first race in 1950 and the opening of the dedicated Road America track in 1956, the roads around Elkhart Lake provided the setting for some great post-war racing. Competing on public streets was ultimately outlawed across the country, but not before drivers risked life and limb in the name of glory in the Wisconsin summer. Cadillac asked us out to the area recently, not to talk racing history, but to look forward at one of the most track capable cars the company has ever offered: the 2016 CTS-V. We got to drive the 640-horsepower beastie for an entire morning of hot laps at Road America, but unfortunately, we're not allowed to tell you about all of that right now. You'll have to wait until the embargo lifts on August 3, at which point we promise a full recounting of our adventure. Having the CTS-V for a full two days though, and in the spirit of the motorsport that imbues the air in Elkhart Lake, we took the Cadillac on a drive around the old 6.5-mile road course. Come for the new Caddy, but stick around to find out what the hell Wacker's Wend is. Cadillac Luxury Performance Videos

Cadillac: The standard of what?

Cadillac's tagline "Standard of the World" goes back to 1908 when it won the Dewar Trophy. While you might think that the moniker and the trophy have something to do with a feat of racing and daring-do against a cadre of British, French, and German marques, it's nothing of the sort. Rather, Cadillac achieved the trophy because of interchangeable parts. The parts they were producing back then were so well-made that Henry Leland, who established Cadillac, was able to disassemble three Model Ks, mix up the parts, and then put together three functioning cars. This amazed the Brits who handed him the trophy, and the "Standard of the World" was born. During the past several months, Cadillac has been producing news releases that would seem as though the company is the Standard of the World: "Cadillac Global Sales Rise 44.2 percent in January ... 18 percent in February ... 22.1 percent in March. . .40.9 percent in April ... 33.8 percent in May ... 7.2 percent in June." Like the Dewar Trophy being about manufacturing not performance, things are not necessarily what they seem. That is, Cadillac's growth is predicated on performance in China, not in the US. Through June, its China sales are 80,357 vehicles for the first five months of 2017, versus 72,073 in the US. The China number is a 75.4-percent year-over-year increase while the US number is a 1.6-percent decrease. For the entire globe, Cadillac has sold 164,174 vehicles. Of them, 65,250 were the XT5. That was followed by the ATS, at 34,277 units. In the US, the XT5 is doing reasonably well, as it has moved 29,798 units during the first six months. The ATS, conversely, is doing not particularly well, as it is down 26.2 percent with sales at just 7,209 for the year so far. To put that into some sort of context, know that Cadillac has sold 7,370 copies of the generally derided XTS, which is down 24.7 percent. The CTS is down 36 percent at 5,059 units, and the only other car in the lineup (we'll pretend that the ELR doesn't exist anymore and it shortly won't), the CT6 sedan, is up 172.7 percent – but they have sold only 5,397 CT6s. While Caddy talks a good game about competing with the likes of the BMW 5 Series and the Mercedes E-Class, know that those two sedans have been sold 17,036 and 20,783 times this year in the US respectively. So what is Cadillac chief Johan de Nysschen to do? According to Reuters, it is to cull the lineup.
