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.

Comparing Cadillac's crazy classy coupes

I just returned from the press launch of Cadillac's new ATS-V, a high-performance version of the US luxury marque's entry-level compact car. While ordinary ATVs offer a choice of a 202-horspower, 4-cylinder, a 272-hp turbocharged four or a 321-hp V-6, this one packs a twin-turbo V-6 that pumps out 464 thoroughbred horses and 445 pound-feet of hard-charging torque. Starting at $62,000 for the sedan and $64,000 for the sexy coupe, ATS-Vs are available with a 6-speed manual (with Active Rev Matching and no-lift shift capability) or an 8-speed automatic with steering-wheel shift paddles. They comes with GM's latest 4-mode Magnetic Ride Control, 5-mode Performance Traction Management (with launch control), competition-spec traction and stability controls, an electronic limited-slip differential, specially-tuned electric power steering, huge Brembo brakes, and added air cooling for their engine, transmission, and rear axle lubricants. They roll on 18-inch Michelin Pilot Super Sport tri-compound summer tires on 9-inch-wide front alloy wheels and 9.5-inch-wide rears. And they will rocket from rest to 60 miles per hour in less than four seconds while delivering 16 city EPA miles per gallon and 24 highway with the automatic and 17/23 with the manual transmission. The obvious purpose of all this technology is to effectively endow Cadillac's latest V-Series models with a rarely achieved true dual personality: go, stop, and corner like race cars on a track, then sooth, coddle, and entertain like luxury cars on the way to and from the track, or work. We had ample opportunity to verify both personalities with multiple hot laps of the Circuit of the Americas (COTA) Grand Prix course, followed by a more leisurely drive on public roads near Austin, TX. Even lacking wheel-to-wheel comparisons, we believe these hot new ATS-Vs are fully competitive with their pricier German competitors, and probably superior in some ways. So now, Cadillac will offer not one but two very sharp-looking, upscale, small-volume, 2016 compact coupes, almost the same size and at similar prices, but with totally different missions: this new high-performance ATS-V and the soon-to-be-upgraded ELR extended-range EV. The key question: why? Aside from its cramped back seat and ridiculous $76,000 starting price, I loved the ELR when it was introduced for 2014.

2013 Cadillac ATS 3.6 AWD

All-Wheel, All Right
There is no escaping the luxury all-wheel drive empire Audi has built for itself over the past 15 years. While nearly every high-end marque has at least one offering with power at all four corners, the hardware can't help but play second fiddle to Ingolstadt's Quattro kingdom. Leather-lined all-wheel drive is simply Audi the way minimum wage is an English degree. But General Motors seems hell-bent on raiding as many established fiefdoms as possible with the 2013 Cadillac ATS. Engineers and designers made no secret of the fact that the baby Cadillac was penned specifically to take on the BMW 3 Series, but Audi should be no less concerned about the newest luxury prince from Detroit.
GM has been stuffing all-wheel drive systems under their vehicles for years, but the effort hasn't come without nasty side effects. Unfortunate understeer, extra ride height, smallish wheels and porky curb weight meant opting for all-wheel drive was like signing your driving pleasure's death warrant. Would you like polished brass or brushed nickel hardware for your right foot's coffin, sir?
