Next-gen GMC Sierra spied with diesel power

The next generation of GM trucks is arriving soon, and we're expecting a huge leap forward over the current lineup. The Chevy Silverado and the GMC SIerra sell extremely well, but haven't done much to move the segment forward in a long time. The Ford F-150 has an all-aluminum body and turbocharged V6 power. The Ram 1500 gained a diesel and coil spring suspension. These spy shots show that diesel may be in the cards for GM. Some quick shots and copious use of flash show what is most likely a tank for diesel exhaust fluid and a diesel particulate filter, both necessary equipment for any modern diesel. It's unclear what form factor that engine will come in, though GM has a number of engines to choose from, including the 2.8-liter inline four that's found in the Colorado and Canyon, though that may be a little light duty for the Silverado and Sierra. Other rumors surrounding the trucks suggest a move to an aluminum cab while retaining a steel bed. That seems like a reasonable move for GM, even if the company was attempting to shame Ford for its move to aluminum a few years ago. Look for more news as early as the Detroit Auto Show in January.

Nissan Leaf has outsold Chevy Volt by 50% so far in 2015

We know, we know. The Chevy Volt and Nissan Leaf sales numbers for mid- to late-2015 aren't all that meaningful because of the impending arrival of the next-gen Volt and the expected but not-yet-totally-confirmed debut of the second version of the Leaf. Nonetheless, tracking the sales of the first two major plug-in vehicles is something that remains interesting to us, if for nothing else that the all-electric Leaf remains slightly more popular than the plug-in hybrid Volt after all this time. If we just look at August, the numbers were basically tied in the US. Chevy sold 1,380 Volts while Nissan moved 1,393 Leafs. But when we take a 10,000-foot view, the differences starts to appear. So far in 2015, GM has sold 8,315 Chevy Volts while Nissan has sold 12,383 Leafs. That means that the Nissan has outsold the Chevy by around 50 percent (to be specific, it's 48.92 percent). Since the two vehicles went on sale in the US at roughly the same time at the end of 2010, 81,672 Volts have been sold, compared to 84,705 Leafs. That's a difference of only 3,033 vehicles, so proponents of both powertrains can hold their heads high. Looking just at last month, Volt sales were 45 percent lower compared to August 2014. So far this year, Volt sales are down 36.7 percent. The Leaf didn't fare any better. Month-to-month, Leaf sales were down 43.7 percent in August, while year-to-date, Leaf sales are down 65.3 percent. Those second-gen models can't come soon enough. As always, we'll have our broader wrap-up of monthly green car sales for August up soon. Stay tuned. Green Chevrolet Nissan Electric Hybrid ev sales

GM files for Z71 Trail Boss trademark

Try as they might to keep their plans a secret, automakers have their hands tipped through a variety of methods – be they through loose lips, spy shots or patent and trademark applications. That's how we know, in this instance, that General Motors is working on (or at least considering) an off-road machine wearing the name Z71 Trail Boss – the name which our compatriots at AutoGuide.com tell us that GM has registered for use on light-duty trucks. Now if that alphanumeric designator sounds familiar, it should. GM has long used it to designate the off-road packages on many of its body-on-frame trucks from Chevy and GMC. These days you can order a Z71 package on the Chevy Colorado, Silverado, Tahoe and Suburban and on the GMC Canyon, Sierra and Yukon. The package typically includes components like a beefed-up suspension bits, high-capacity air cleaner and underbody protection plates. The Trail Boss designator would seem to suggest something further reaching than a suspension package, though. Just what it would entail we don't know; minds immediately start running toward Chevy or GMC going after the Ford F-150 Raptor, but we'll likely be looking at something closer to the Trailhawk packages Jeep offers on the likes of the Renegade and Cherokee.
