2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.

Final C6 Corvette built in Bowling Green

With all of the attention given to the 2014 Chevrolet Corvette Stingray lately, you could be forgiven for thinking that it's already well along in production, yet tooling up for the new C7 has only just begun. In fact, production of the outgoing C6 generation in Bowling Green, Kentucky just halted on Thursday.
As the C6 has aged, production numbers have predictably ebbed along with demand, but this year, the addition of the 427 and 60th anniversary models resulted in an uptick in vehicles built - this, despite a model year shortened by around 25 percent to accomodate the new model changeover. The final C6 Corvette ever, No. 13,466 built this year, was a white 427 Convertible destined for the General Motors Heritage Center museum. The car's 7.0-liter V8 heart was assembled by Corvette chief engineer Tadge Juechter himself.
In total, Bowling Green pushed out 215,100 C6 Corvettes over nine years. If you're still a C6 fan at heart and are hoping to get a good deal on a phase-out model, step lively - Chevrolet reportedly had about 6,100 unsold units, which Autoweek suggests is good for around five and a half months of supply at the model's current sales rates. Given that demand will likely slacken even further as the C7 draws closer, that should be a big enough stockpile to keep dealers satisfied until 2014 Stingrays begin showing up on their forecourts in December.

Opel's own ad shows Ampera-e beating Opels in drag race

The Opel Ampera-e isn't expected to set any world records on a quarter-mile drag strip. But when it comes to crossing a major boulevard, though, the European version of the Chevrolet Bolt electric vehicle will more than hold its own, potentially scaring inattentive pedestrians everywhere. According to a 35-second video posted by General Motors' Opel division, at least. Opel set up the Ampera-e against four other small-and-sporty vehicles, including racing versions of the Opel Adam and Opel Astra as well as stock versions of the Opel Insignia and Corsa (what, you expected a Corvette to be in there?). With the EV's off-the-line torque as a selling point, Opel showed the Ampera-e beating the other vehicles in a 30-meter (100-foot) drag race. Of course, the video also shows the EV getting passed by some of the others soon after, but the point was made. Opel doubled down by adding the tagline "Fun to Drive" at the end of the video. While Opel hasn't revealed the single-charge range of the Ampera-e, it should be roughly the same as the Chevrolet Bolt, which will be about 200 miles. In addition, the Ampera-e, like the Bolt in the US, will get 200 horsepower from its electric motor, and will be able to go from 0 to 60 miles per hour in less than seven seconds. The Ampera-e will debut at the 2016 Paris Motor Show later this month. General Motors said in February that Europe would get the Ampera-e by next year. Opel had previously used the Ampera name with the Euro version of the Chevrolet Volt extended-range plug-in.
