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.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.

2020 Lincoln Corsair vs 2020 Cadillac XT4 | How they compare on paper

The 2020 Lincoln Corsair compact crossover was introduced this year to replace the aging MKC. Our first impressions are that it's a thoroughly competent luxury machine, but where it fits in the market is interesting. Given its size and price tag, the Corsair basically slots in-between compact segments, with vehicles like the Audi Q3 below and Audi Q5 above. It's a distinctive position to be in, but not a unique one, as there's another comparably sized and priced SUV -- and an American rival, no less. The Cadillac XT4 was launched just last year to be its company's smallest crossover, boasting compelling design and ample technology features.  So which is better? To give you some idea, let's take a look at each vehicle's horsepower, torque, fuel economy, space, pricing and some slightly more subjective aspects about their luxuriousness and feature sets. You'll find all the nitty gritty numbers below, followed by more detailed analysis. And if you'd like to compare other luxury crossovers, be sure to check out our comparison tool. Engines, drivetrains and driving impressions Both the Corsair and XT4 come standard with turbocharged 2.0-liter four-cylinder engines, but the Corsair's is more potent with 250 horsepower and 275 pound-feet compared with the 237 horsepower and 258 pound-feet of the Cadillac. And to seal the deal, the Corsair has an optional turbo 2.3-liter engine with 280 horsepower and 310 pound-feet of torque. That's not only vastly better than the Cadillac, but one of the most powerful outputs in the compact luxury SUV segment. Both vehicles have standard front-wheel drive with optional all-wheel drive on the base engines. The 2.3-liter Corsair has all-wheel drive standard. The Cadillac does boast an extra cog in its transmission over the Corsair's eight-speed automatic, but there's not necessarily an advantage or disadvantage to be gleaned from that. When it coes to fuel economy, the Cadillac is victorious with a 26 mpg combined rating for the front-drive model, with the front-drive 2.0-liter Corsair coming just behind with 25 mpg combined. It's a three-way tie for third with the all-wheel-drive XT4, all-wheel-drive 2.0-liter Corsair and 2.3-liter Corsair all returning 24 mpg combined. Of course, the all-wheel-drive Corsairs have a small advantage here in that it delivers more power and torque than the Cadillac with the same fuel economy.
