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.

Expect greater differentiation in GM's next-generation SUVs

General Motors says its next-generation Chevrolet Tahoe, Suburban, GMC Yukon and Cadillac Escalade models will offer shoppers improved interior differentiation. Car and Driver recently caught up with Chris Hilts, GM's creative manager of interior design, who said that the cabins will all feature unique instrument panels, consoles, center stacks and switchgear moving forward. Apparently GM is now aware that consumers may be bothered by the fact that today's $85,000 Escalade has effectively the same cabin as a $45,000 Tahoe. Hilts says SUV buyers want more refinement than their pickup purchasing counterparts - and those same buyers also want their SUVs to have more exterior differentiation between the company's Silverado and Sierra pickup lines. Shocking.
That all sounds good to us, but we've heard this song and dance before. GM made big waves about how different the new-for-2013 Silverado and Sierra would look from each other, but judging by what we've seen so far, GM's stylists are painting in shades rather than with the full spectrum.

2020 Cadillac CT4 spied completely undisguised for the first time

A few weeks ago, Cadillac gave us our first look at its new small luxury sports sedan in the form of the CT4-V. This was a bit unusual considering the company hadn't shown us the regular one yet, and the reveal is still off in the not-too-distant future. But we were lucky enough to catch a normal 2020 Cadillac CT4 parked at a local gas station completely and totally undisguised. Based on what we know about other recent Cadillacs and their trim and design, this CT4 is probably a Luxury or Premium Luxury trim, since it has plenty of bright chrome and red taillights instead of dark gray ones. The differences from the CT4-V are subtle. The mesh grilles of the V are swapped for a main grille studded with small Cadillac badge shapes and the lower grille has simple slats. The little air intakes by the lower sections of the running lights are smaller than the ones on the V. This car also lacks the V's side skirts and wider canards on the edges of the front bumper. There doesn't appear to be a rear spoiler either. While we've had a good look at the exterior of the CT4, we'll have to wait until the car's full reveal later this year to know what's under the skin. We do know that it will continue to use the Alpha platform shared with the CT5, Camaro and the old ATS and CTS. We suspect the base engine will be the same 2.0-liter turbocharged inline-4 from the CT5, which makes 237 horsepower and 258 pound-feet of torque. Since the CT4-V uses a turbo 4-cylinder that makes 320 horsepower and 369 horsepower, there might not be a V6 option for the regular CT4. The CT5's twin-turbo 3.0-liter V6 makes more power and torque, so that's out, and the old ATS's naturally aspirated V6 made 335 horsepower and 285 pound-feet of torque, which would be uncomfortably close the CT4-V's specs. But we could see a V6 of some sort in an even more potent V iteration of the CT4 later.
