Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.

Was the C7 Corvette cut from Beyonce's Super Bowl halftime show?

Someone was bound to receive a free 2014 Chevrolet Corvette Stingray during the Super Bowl XLVII festivities; it just wasn't who we thought it was going to be. Despite a report back in December that superstar Beyoncé Knowles would be getting an all-new Corvette during her halftime performance, that turned out not to be the case. Joe Flacco, starting quarterback for the Baltimore Ravens, did in fact win a Corvette for his MVP performance.
So what transpired that prevented Beyoncé from rolling on stage in the new Chevrolet? Anyone who knows isn't telling, but according to Yahoo! Autos, General Motors said that for one reason or another a deal "did not work out," and it appears to have been an eleventh-hour change. Regardless of who's to blame or what prevented this from happening, we're sure Chevy has had no problems getting attention for the C7 Corvette since it was introduced last month.

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.
