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.

2021 Cadillac Escalade's EPA highway fuel economy is worse than before

EPA fuel economy estimates for the 2021 Cadillac Escalade are out, and the news is mostly not good. The redesigned SUV sees slim to no improvement in the Feds' city ratings, and its highway numbers are considerably worse than before. These are estimates for the standard 6.2-liter V8. Figures for the no-cost-optional 3.0-liter turbodiesel six have not been released yet. Specifically, the rear-wheel-drive 2021 Escalade has estimates of 15 mpg city, 20 mpg highway, and 17 mpg combined. Compared to the outgoing 2020 version, powered by the same 6.2L V8, those numbers represent a 1 mpg improvement in city (the lone piece of good news) but are 3 mpg worse on the highway. With all-wheel drive, the 2021 Escalade can't even get out of the teens, with EPA ratings of 14 mpg city, 19 mpg highway, and 16 mpg combined. That's the same city rating as before and a 2 mpg decline versus the 2020 model's highway rating. For further comparison, cross-town rival Lincoln's Navigator with its 3.5-liter turbo V6 manages 16 mpg city and 22 mpg highway (RWD) and 16/21 with AWD. No one expects an ultra-large, body-on-frame, three-row SUV to achieve Prius-like levels of fuel efficiency, but it's pretty rare these days to see such backsliding with a fresh redesign. Here's hoping the diesel variant will have a happier story to tell. Related Video:

Economy-car buyers increasingly get the best deal on technology

One of the great things about technology is – with the exception of Apple products – consumers get more for their money every year. For example, the first 1GB USB drive I bought in 2005 cost me $30. Today you can get 10 for that price, delivered to your door thanks to Amazon. The same goes for car tech. Features such as navigation and Bluetooth started out on high-end vehicles before trickling down to entry-level cars. Same with driver assist features ranging from rearview cameras to forward collision warning with automatic emergency braking — so now it's not only rich people who are protected in car crashes. I've found that this democratization of tech has reached a point where amenities on low-cost cars can be as good — and sometimes even better — than those on vehicles costing tens of thousands of dollars more. While attending a media event for the launch of the all-new 2019 Toyota Corolla Hatchback, I was impressed by the car's cool styling and go-kart performance. Equally noteworthy is the amount of standard tech on the low-cost hot hatch. (Pricing will be announced later this month, but expect it to come in a bit higher that the current Corolla iM's roughly $19,000 base.) Even the base SE CVT trim of the 2019 Corolla Hatchback comes with an 8-inch touchscreen and Toyota's Entune 3.0 infotainment system. Among other features, Entune 3.0 provides Wi-Fi capability, Amazon Alexa connectivity, the Entune App Suite for integration of smartphone apps such as Pandora and Yelp and, for the first time in a Toyota, Apple CarPlay (but no Android Auto). The 2019 Corolla Hatchback is also the first North American vehicle to get the second-generation Toyota Safety Sense (TSS) suite of driver assists that's also standard on the base model. TSS 2.0 includes Toyota's Pre-Collision System (forward collision warning with automatic emergency braking) with new daytime and low-light pedestrian detection and daytime cyclist detection features, lane keeping and lane departure alert with steering assist, auto high beams, adaptive cruise control, and road sign detection. While the 2019 Corolla Hatchback sets a new benchmark in standard tech on a budget-mobile, competing cars aren't far behind. The 2018 Honda Fit LX, for example, includes forward collision warning with automatic emergency braking, lane departure warning and assist and adaptive cruise, while the automaker's Lane Departure Mitigation and Lane Watch camera system is added the two top trims.
