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.

How GM's grueling 24-hour test gets the kinks out of its performance cars

One of the biggest challenges automakers face when designing a high-performance car is making sure that it is both fast and reliable. For General Motors, any car that might be taken to the track by its owner - like the Corvette, Camaro Z/28 (shown above) and the Cadillac CTS-V, for example - undergoes a rigorous and strenuous 24-hour test by engineers at the Milford Proving Grounds, as pointed out by Car and Driver.
We've posted on this topic in the past - on a video showing the Camaro ZL1 being brutalized, for instance - but this article gives a more in-depth look at what actually happens behind the scenes... including what that poor ZL1 went through. Though the test isn't for 24 hours straight, the cars are pushed as hard as possible by some of GM's best drivers with only the brakes and tires replaced frequently.
We don't want to ruin the fun for you, but it is an interesting article that tells just some of what GM does to develop its sports cars. Check out the full article over at Car and Driver for the rest of the story.

2019 Cadillac ATS-V, CTS-V get cool color, weird name

A lot of special-edition cars are really not all that special. They consist of some special paint combo, and maybe a couple of optional features made standard. The Cadillac ATS-V and CTS-V Pedestal Editions are actually pretty much that. But they make up for the mild content list with a really nifty color, great exclusivity and also a weird name. They also help celebrate the ATS-V and CTS-V before they disappear from the line. First let's take a look at the color. It's a shade called Bronze Sand Metallic. It's an earthy, dark brown with a yellow-green tinge to it. We suspect it probably looks more impressive in sunlight, and it's unlike most browns we've ever seen. It's sure to garner attention in any parking lot stuffed with black, silver and white luxury cars. It's matched with sand-colored ultrasuede inserts and bronze-threaded carbon fiber trim on the interior that look sumptuous. Each also comes with carbon fiber exterior trim, red brake calipers, and the CTS-V adds the performance data recorder and Luxury Package. The name really is strange, though. Cadillac says, "The special-edition variants are named in tribute to Cadillac V-Series' time spent at the pinnacle of luxury high-performance." So it seems the thinking was that these cars are up on a pedestal compared with other performance luxury cars. But even in that sentence from Cadillac, there's a word that would be better and more recognizable for excellence: pinnacle. We can think of other great words for marking the peak or the top of performance and luxury, words such as "apex" or "climax." Well, maybe not that one. One of the big appeals of these cars is that there won't be many of them. There will only be 300 built, and that's the total between the ATS-V coupe and CTS-V sedan. The final total for each model will be determined by orders. Ordering opens up on the first week of November, with production coming at the end of that month. The cars will only be available to buyers in the U.S., Canada and the Middle East. There are significant price differences between the two cars. The ATS-V coupe starts at $77,090, while the CTS-V starts at $102,590. That puts the ATS-V at roughly $10,000 more than a base model, and the CTS-V at roughly $12,000 more than its base model.
