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.

Camaro driver clocked at 171 miles per hour

Chevy's 2016 Camaro SS is a fantastic piece of automotive engineering. It is also, apparently, very, very fast. This latter fact was perfectly illustrated when, on April 8, a Camaro SS driver was nailed in Two Harbors, Minnesota for doing 171 mph. According to WFAA, the unnamed speed demon was flying down Highway 61 near Two Harbors when Hermantown, MN Deputy Police Chief Shawn Padden clocked him at an eye-watering 171 mph. He then recorded the speeder at 168 and 141. At the time, Deputy Chief Padden was working with Minnesota State Patrol on an anti-DWI program called "Toward Zero Deaths". Padden, who was interviewed by the Duluth News Tribune, said he was surprised at the driver's sheer speed. "When he went by me, it was a blur," Padden told the News. "You get used to seeing people going 65 or 70 and what that looks like. But I've never seen anything like this. It's like a rocket on wheels." Fadden chased the Camaro down eventually, but it took some doing. To catch the Camaro, he pushed his Dodge Charger Pursuit to 135 mph just to get into range so the Camaro could see his emergency lights. The speeding driver was ticketed for careless driving, but may lose his license due to a Minnesota law that gives courts the option of revoking licenses for drivers caught doing more than 100 mph.

Why does the Corvette Stingray have so many vents? Here's why

Just looking at the new 2014 Chevrolet Corvette Stingray, it's not hard to see that the car's design was created with aerodynamics at the forefront, but Chevrolet designers point out exactly what went into designing the iconic coupe in a pair of recently released videos. The videos show the Corvette going through early design phases, including clay models and wind tunnel tests, as well as talking to the car's chief engineer, Tadge Juechter.
Both videos help explain various aspects of the C7 Corvette, but it's the aero tuning of the car that is most interesting. This includes extra attention paid to the lower air dam and vented hood to help reduce drag and lift, while the rear quarter inlets are for differential and transmission cooling. Juechter said that some of these aero-tuned elements were inspired from GM's involvement in racing.
If you have about five minutes and you can't get enough information about the new 'Vette, then check out the videos posted below.
