Cruze Diesel Road Trip reveals the good and bad, but no ugly

Most of us have strong opinions on diesel-powered cars based on our perceptions of and experience with them. I used to thoroughly dislike oil burners for their noise, smoke and lackluster performance, and the fact that they ran on greasy, smelly stuff that was more expensive than gasoline, could be hard to find and was nasty to get on your hands when refueling. Those negatives, for me, trumped diesel's major positives of big torque for strong acceleration and better fuel economy. Are any of those knocks on diesel still valid today? I'm not talking semis, which continue to annoy me when their operators for some reason almost never shut them down. At any busy truck stop, the air seems always filled with the sound – and sometimes smell – of dozens of big-rig diesels idling endlessly and mindlessly. Or diesel heavy-duty pickups. Those muscular workhorses are far more refined than they once were and burn much less fuel than their gasoline counterparts. But good luck arriving home late at night, or departing early morning, without waking your housemates and neighbors with their clattery racket. No, I'm talking diesel-powered passenger cars, which account for more than half the market in Europe (diesel fuel is cheaper there) yet still barely bump the sales charts in North America. Diesel fuel remains more expensive here, too few stations carry it, and too many Americans remember when diesel cars were noisy, smelly slugs. Also, US emissions requirements make them substantially more expensive to certify, and therefore to buy. But put aside (if you can) higher vehicle purchase and fuel prices, and today's diesel cars can be delightful to drive while delivering much better fuel efficiency than gas-powered versions. So far in the US, all except Chevrolet's compact Cruze Diesel come from German brands, and all are amazingly quiet, visually clean (no smoke) and can be torquey-fun to drive. When a GM Powertrain engineering team set out to modify a tried-and-true GM of Europe turbodiesel four for North American Chevy Cruze compacts, says assistant chief engineer Mike Siegrist, it had a clear target in mind: the Volkswagen Jetta TDI 2.0-liter diesel. And they'll tell you that they beat it in nearly every way. "I believe we have a superior product," he says. "It's powerful, efficient and clean, and it will change perceptions of what a diesel car can be." The 2.0L Cruze turbodiesel pumps out 151 SAE certified horses and 264 pound-feet of torque (at just 2,000 rpm) vs.

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.

Corvette Stingray Convertible images mysteriously appear on web, so we add our own

It was inevitable that we'd see the 2014 Chevrolet Corvette Stingray topless at some point, but that didn't make us any less interested when a pair of supposedly leaked official images showed up on theautoinsiderblog.com last week. We posted them on our Facebook page, but held off reporting on them here until we could get a little more information.
Those images, which feature a dark red car on a sterile black studio background, supposedly first appeared on the website of diecast model maker Maisto. A Chevrolet spokesman has been reported saying that they are "not official images released by Chevrolet PR," which isn't a denial they're the real deal, but neither is it a confirmation.
Close examination of the photos suggest they could be official shots of the Corvette Stingray Convertible, and while some have doubted their authenticity due to a lack of vents (which were seen on the C7s that debuted in Detroit last week), it could be that the images are of a base model car without the Z51 package that doesn't require the extra venting and cooling.
