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.

Stop-start standard in four-cylinder 2015 Chevrolet Impala

Chevrolet has announced that it will include stop-start technology as standard in the entry level 2015 Impala. The result is a nearly five-percent improvement in city fuel economy, also known as one mile per gallon, up to 25 mpg, combined. The 3.6-liter V-6 Impala will not feature stop-start. The 2015 Impala comes equipped with Chevrolet's 2.5-liter Ecotec four-cylinder engine, which will also offer 22 mpg in the city, and 31 on the highway. The 3.6-liter V-6 Impala will not feature stop-start and the mild-hybrid eAssist model from the 2014 MY, which got 29/25/35 combined/city/highway mpg, has been discontinued. Chevrolet spokesman Chad Lyons told Green Car Reports that not even one percent of the 2014 Impalas purchased were the Eco model. So Chevy is trying something different. With a seamless driving experience in mind, the new Impala's stop-start tech features software that governs under what conditions the feature will activate. The engine won't shut off if the car has not reached a speed of six miles per hour, so the start-stop won't be cycling during traffic jams. It can also fire the starter even if the engine has not come to a full stop, which quickens reaction time, particularly in instances of what Chevrolet calls "change-of-mind events." The stop-start function uses information about cabin temperature and humidity as well as battery charge to help determine whether or not to shut off the engine. The 2015 Impala has been engineered to reduce NVH, which will also help create a smoother stop-start experience for occupants, Chevy says. Motor mounts have been updated, and a burlier starter motor will help restart the engine after a stop. The Impala follows the 2014 Malibu as Chevrolet's second vehicle to feature stop-start tech. The four-cylinder model currently makes up over 30 percent of Impala sales. The 2015 Impala will be available beginning this summer, with a base MSRP of $27,735 (including destination charges). And while one MPG isn't a huge difference, neither is the price increase of just $50 for a bit of eco-minded innovation. Read on for more details in the press release below. Chevrolet Makes Stop/Start Standard in 2015 Impala Technology improves city fuel economy by 5 percent 2014-05-22 DETROIT – Stop/start technology will be standard on the 2015 Impala base 2.5-liter ECOTEC® engine, an addition that improves the vehicle's city fuel economy by nearly 5 percent, or one mile per gallon.

Porsche 911 tops a list of must-have classics, but No. 2 is more of a surprise

No surprise here: In Europe, the Porsche 911 is the most sought-after classic car. Surprise here: Slip-streaming the 911 in the most sought-after chart compiled by the Car & Classic marketplace is the Ford Mustang. Using the Google search engine as a means to pick the winners, as well as the average prices achieved on the “Car and Classic” website, the venerable 911 was tagged 1.45 million times per month according to data stretching back 15 years. The number of 911Â’s sold though the C&C marketplace was 21,141, at an average price of 58,409 pounds, or $74,300. FordÂ’s pony car, still a popular choice for buyers in Europe, placed second on the list with 1.2 million monthly searches. The average sales price over 15 years was 31,107 pounds ($39,570), and the number of older Mustangs sold reached a total of 8,332. Models that also finished among the charted top 10 include the Land Rover Range Rover, the Corvette, the ultra-classic British favorite Jaguar E-Type and the BMW 3 Series. “Whilst a 1973 Porsche 911 Carrera 2.7 RS could set you back the best part of GBP500,000 ($636,000), there are many more affordable models, which bring the average sale price of a 911 on Car & Classic to GBP58,000 ($73,800) – the third highest average selling price of any make and model on the site,” explained Dale Vinten of Car & Classic. According to the site, the Jaguar fetched the highest average selling price: a whopping 89,000 pounds, or $113,000. But thatÂ’s peanuts compared to a Series 1 Roadster in excellent condition, said Vinten. For that, “you can expect to spend up to GBP250,000 ($318,000), A Series 2 or 3 will cost less, as they are not as desirable, but in decent condition you can expect to pay around GBP40,000-GBP50,000. Even a barn find 1969 E-Type Series 2 Roadster can set you back to the tune of GBP33,000 ($42,000)." Launched in 2005, Car & Classic is among EuropeÂ’s most popular classic car clearinghouses. It also runs a stand-alone auction site.
