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.

2017 Cadillac CT6 Plug-in Hybrid is the most efficient and torquey CT6 of all

Cadillac is returning to the hybrid game after discontinuing the ill-fated ELR, this time with an existing car and a new drivetrain. The company has taken its CT6 flagship and given it a turbocharged 2.0-liter four-cylinder, a pair of motors, and a big battery pack. The result of this combination is a CT6 that manages a rating of 65 MPGe, can go 30 miles on a full electric charge or 400 miles combined with the engine. The powertrain produces 335 horsepower and 432 lb-ft of torque. That's the same amount of power as the 3.6-liter V6 CT6, and more torque than that engine or the twin-turbo 3.0-liter V6. Cadillac claims the CT6 plug-in is capable of hitting 60 miles per hour in 5.2 seconds and reaching a top speed of 150 mph. The green and grunty CT6 plug-in will be available this coming spring, and it will have a premium price of $76,090. Cadillac says that its equipment list is comparable to the CT6 Premium Luxury trim level, which starts at $64,590 with the 3.6-liter V6, and $68,590 with the twin-turbo V6. However, in addition to the hybrid powertrain, Cadillac throws in a number of features that are options on the conventional gasoline models. To get the hybrid's rear seat infotainment system and enhanced night vision, a buyer would have to add $5,800 in option packages. That still leaves the twin-turbo model $1,700 shy of the hybrid, but that's not a terrible trade for the option of fuel-free driving for at least some of the time.

2016 Cadillac CTS-V First Drive [w/video]

A million insects lost their lives today. Boxelder bugs and mayflies making the ultimate sacrifice in Elkhart Lake, their carapaces no buffer against a rocketing rectangle of safety glass. Their bodies gorily streaking into spangles along the diamond-faceted face of the Cadillac CTS-V. Road America is a four-mile ribbon of pavement snaking its way through the emerald center of the country's northern heartland. Since the 1950s it's seen uncountable fields of diverse racing machinery rocket over its hills and around its 14 corners. I would imagine that on those occasions the tramping of onlookers and hubbub of vehicles, both competitive and commonplace, would dissuade a great number of our six-legged friends from making their way onto the track. But today it's just me turning laps. Inconceivably just one journalist, driving the baddest roadgoing Cadillac ever made, on one of the loveliest circuits America has ever carved out. So big-winged bugs made it out to me in a vast array and a tragic sum, and I drilled through them oblivious to anything but one of the greatest days of driving I've ever had. Cadillac has turned its CTS-V from a performance sedan to a monster. For 2016 Cadillac has turned its CTS-V from a performance sedan to a monster worthy of the carnage described above. The words "epic" and "awesome" are hilariously overused on the Internet, but in the case of the CTS-V's 6.2-liter supercharged V8, their literal meanings are fitting. The capacity to produce 640 horsepower and 630 pound-feet of torque is astounding. Feeling those outputs come to growling life under my foot arch, uncorks different reactions in my brain as the day wears on: first trepidation, next cautious optimism, finally red-eyed bloodlust. A glance at the power and torque curves will show you that the charged V8 behaves more like a naturally aspirated thing than a turbo'd on/off switch. Peak torque arrives at 3,600 rpm, horsepower at 6,400, giving the engine lovely, linear power delivery. Even with top torque happening near the middle of the tach, there's no small amount of the stuff when the engine first spins up, so launching all 4,145 pounds of Detroit iron still feels exotic. Launching all 4,145 pounds of Detroit iron still feels exotic. On the roads around Wisconsin, using all of the available power is hardly advisable, but I have no trouble driving this fast car slowly (sort of).
