Mustang retakes monthly pony car sales crown from Camaro

Going back to their origins in the Swinging '60s, the Ford Mustang and Chevrolet Camaro have been fierce rivals for fans' hearts and dollars. Historically, the Ford often led in volume, but Chevy took the muscle car top spot in 2009 upon the Camaro's rebirth. However, with the launch of the latest Blue Oval pony car, the tide is turning back in Ford's favor. November was the first full month of sales for the new 2015 Mustang, and according to TheDetroitBureau.com, the model did spectacularly well. The Blue Oval shifted 8,728 of them, up 62 percent from same month last year, with the automaker proclaiming it the model's best November sales since 2006. Conversely, 4,385 units of the Camaro were delivered, down 13.5 percent year-over-year, meaning its sales were roughly half that of the new-generation Mustang. Ford is understandably happy with the results, and product development director Raj Nair even hinted to TDB that another version of the Mustang might be unveiled at January's North American International Auto Show. Rumor has it that the model will be the even more potent Shelby Mustang GT350R. Despite the Mustang's November success, the Camaro outsells it year to day. So far in 2014, Ford has sold 73,124 Mustangs versus 79,669 examples of the Camaro. With December offering the last chance for an overtake, the Bowtie may yet remain king for this year's sales crown. A new Camaro is peeking over the horizon, as well. It's reportedly moving to the Alpha platform used by the Cadillac ATS, and production could start in late 2015. Prototypes are already testing at the Nurburgring, and camouflaged examples have been spotted weirdly being compared to its '80s forefather.

First 2015 Chevy Corvette Z06 engine blows up at just 891 miles

You've waited and watched and waited some more for the arrival of your 650-horsepower, $78,000 Chevrolet Corvette Z06. Finally, that joyous day arrives and you eagerly, but gingerly, begin to break-in the 6.2-liter supercharged V8 monster under your hood. Then 900-odd miles after delivery, your excitement grinds, quite literally, to a halt. That's what the owner of one 2015 Z06 claimed happened to him when a simple break-in drive resulted in a lunched engine. The owner, known as Lawdogg149 on Corvette Forum, says he was out breaking-in his car ahead of a January track event when it happened. "While making a pull from 35 miles per hour, I accelerated and shifted short of redline, and boom - the car began knocking. I pulled over and popped the hood. I could hear a loud knock coming from the No. 6 cylinder area along with a serious, grinding, metal-on-metal sound coming from the supercharger area," Lawdogg wrote. A subsequent trip to the dealer confirmed his concerns, with the service facility telling Lawdogg that the No. 6 valvetrain had failed. The dealer couldn't research the issue further, though, as General Motors requested the engine be returned for a more thorough evaluation. The good news for the Z06's unlucky owner, at least, is that GM will be covering the engine replacement under warranty, an expense that Corvette Forum estimates is a nearly $24,000 procedure. At this point, the two leading theories behind the engine's detonation involve a manufacturing defect – which could be why GM is so keen to tear the blown powerplant down – or a mistake on the part of Lawdogg. As Motor Authority points out, such an error could be something as simple as the Z06's owner accidentally shifting to first rather than third during his 35-mph pull. If, however, there's a deeper manufacturing problem with the Z06's engine, this might not be the only case we end up hearing about.

Next-gen GM SUVs caught wearing new boxy bodies [w/video]

We recently drove the brand-new 2014 Chevrolet Silverado and found it to be vastly improved compared to the outgoing model. And now that The General's pickup trucks have been squared away, it's time to focus our attention onto their passenger-friendly companions, the Chevrolet Tahoe and GMC Yukon (above).
Our spy photographers have passed along a huge smattering of photos (and a video), showing the new SUVs out testing. Both the short- and long-wheelbase models were spied, and while the overall shape of the vehicles hasn't changed all that much, we expect the updates to be substantial. In addition to new powertrain options, like GM's new small-block V8, we expect the interiors of both SUVs to get massive makeovers, providing better materials throughout their cabins and quieter, more refined environments. We even hear that some trick new suspension developments may be in store for upper-end models.
Visually, these spy shots allow us to see a couple of new details on the SUVs' front and rear fascias, including LED running lamps on the Yukon and some interesting LED taillamp treatments. Of course, the obvious third party missing from this set of photos is the Cadillac Escalade, but as we reported earlier, GM is working to further differentiate the 'Slade from the rest of the fullsize SUV lineup, and is working to make the new model "much less ostentatious."
