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.

Recharge Wrap-up: Tesla factory tour video, Obama rejects Keystone XL

Tesla takes us on a 90-second factory tour in a new video. In the footage, we see humans and robots hard at work putting together the electric cars we all know and love. Pieces of the manufacturing process are interspersed with larger shots of the factory floor. In the end, we see the finished product leave the factory and speed off onto a cone course. Check it out in the video above. President Obama has rejected the proposed Keystone XL oil pipeline. After a seven-year review, he says it would not be in America's interest to build the 1,179-mile pipeline to bring oil from Canada's tar sands to the Gulf of Mexico. He cites passing a bipartisan infrastructure bill as a better way to create jobs, says US gas prices are already falling, and that reducing reliance on fossil fuels is a better way toward energy security. "The industry can find a different way to move that oil," says Christine Tezak, energy market analyst at ClearView Energy Partners. "If prices go up, companies will get the oil out."

Donations raised from the auction will help the organization bring student robotics projects to communities in need of greater science, technology, engineering and math (STEM) education representation. "The Volt exemplifies technology, and behind the next-generation Chevrolet Volt is a diverse team of engineers who understand the power of science and math," says Chevrolet Marketing Director Steve Majoros. "FIRST brings science and math alive outside the classroom, just like we are bringing it alive on the road." Read more from Chevrolet. Nissan has been ranked among the top five percent of global corporations in the Carbon Disclosure Project's (CDP) 2015 Climate Change Report. Nissan scored a perfect 100 points in CDP's Climate Disclosure Leadership Index. Nissan's successful Leaf EV, as well as its efforts to reduce well-to-wheel CO2 emissions by 90 percent by 2050, earned the automaker its high marks. "Nissan is providing customers with innovative products and promoting effective use of energy and resource by increasing sourcing diversity, such as with renewable energy and recycled materials," says Nissan Corporate Vice President Joji Tagawa. "We will continue our activities to achieve our environmental philosophy of 'a Symbiosis of People, Vehicles and Nature.'" Read more in the press release below.

GM recalling 1.4 million older vehicles for oil leak fire risk

General Motors is recalling 1,411,332 older vehicles with its 3.8-liter V6 yet again due to a fire risk. Specifically, there are 1,283,340 of them in the US, and the affected models are the: 1997-2004 Pontiac Grand Prix 2000-2004 Chevrolet Impala 1998-1999 Chevrolet Lumina 1998-2004 Chevrolet Monte Carlo 1998-1999 Oldsmobile Intrigue 1997- 2004 Buick Regal The fault with these vehicles is that oil can drip onto the hot exhaust manifold during hard braking, which can potentially cause of fire. In the last six years, there have 19 reported minor injuries from this problem but no crashes or fatalities, according to the company. Spokesperson Alan Adler also told Autoblog: "GM has reports of 1,345 fires in vehicles that were repaired under two previous recalls for this issue." At this time, GM is still developing a remedy for the problem. According to Adler, the company advised owners to park these vehicles outside for the previous recalls. "The cars can be safely driven. In cases where a customer reported an engine fire while driving, smoke was reported, which would be an indication of a malfunction," he said. This is GM's fourth recall for this problem since 2008, according to The Detroit News. At one point it was believed that aging valve cover gaskets allowed the oil to leak out and drip onto the manifold. A campaign in 2009 covered nearly 1.5 million of these models through the 2003 model year for the same issue. At the time, dealers installed new spark plug wire retainers as a fix.

GM is working on a remedy. The company is aware of post-repair fires in some vehicles but no crashes or fatalities. There have been 19 reported minor injuries over the last six years. These vehicles with 3.8-liter V6 3800 engines are affected: 1997-2004 Pontiac Grand Prix, 2000-2004 Chevrolet Impala, 1998-1999 Chevrolet Lumina and 1998-2004 Chevrolet Monte Carlo, 1998-1999 Oldsmobile Intrigue and 1997-2004 Buick Regal. Including Canada, Mexico and exports, the total population is 1,411,332.
