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.

GM recalling over 243,000 crossovers over possible seat belt defect

The summer of 2010's recall hit parade continues unabated today, with General Motors having just announced that it is asking 243,403 owners of its 2009-2010 Lambda crossovers to bring their three-row haulers in for inspection. The culprit? Second-row seat belts in select Buick Enclave, Chevrolet Traverse, GMC Acadia, and Saturn Outlook CUVs have "failed to perform properly in a crash."
According to GM, a second-row seat-side trim piece is to blame, as it can impede the upward rotation of the buckle after the seat is folded flat. As a result, if the buckle makes contact with the seat frame, cosmetic damage can occur, potentially requiring additional force to operate the buckle properly. So far, no great shakes, but in the process of applying that additional force, the occupant may push the buckle cover down to the strap, potentially revealing and depressing the red release button. As a result of this, the belt may not latch, or in certain cases, it may actually appear to be latched when, in fact, it isn't.

Weekly Recap: Revisting the BBC report that ended Jeremy Clarkson's Top Gear run

Jeremy Clarkson's long run as a Top Gear host has come to an end, and the reason is clear: His physical assault on one of the show's producers crossed a line, and the government-owned BBC couldn't tolerate it. The incident between Clarkson and Top Gear producer Oisin Tymon was initially described as a "fracas," and Clarkson was suspended. But his popularity and widespread support – even British Prime Minister David Cameron weighed in – suggested that the controversial Clarkson might be given yet another chance. The BBC put this to rest Wednesday when it sacked Clarkson and revealed the findings of its investigation. The report spelled out how Clarkson struck Tymon on the patio of a North Yorkshire (UK) hotel, leaving him with a bloodied, swollen lip. It was severe enough that the producer sought medical treatment. During and after the attack, Clarkson shouted expletives at Tymon and threatened to fire him. The noise carried into the hotel's dining room and even to a bedroom. Local police investigated the incident, but Tymon isn't pressing charges. The huge audience numbers, Clarkson's popularity and the high-octane excitement of Top Gear all melted away in the eyes of BBC director-general Tony Hall, who saw an attacker and a victim. "For me a line has been crossed," he said in a statement. "There cannot be one rule for one and one rule for another dictated by either rank, or public relations and commercial considerations." In that moment, Clarkson was the bad guy, though he was actually the one who reported it to the network and made repeated attempts to apologize to Tymon. He's also urged the media to leave the producer alone. Hall voiced regret in the statement that announced Clarkson's contract would not be renewed, but the BBC decided to move on. Rumors are swirling about possible replacements for Clarkson. The network says it wants to continue Top Gear in 2016 and is looking to air the rest of this season's episodes. Despite the controversy, the show has a global audience of 350 million viewers and is one of the BBC's most valuable properties. It's unclear what Clarkson's co-hosts, James May and Richard Hammond, will do, as their contracts were also reportedly up to be renewed.
