Watch a 2015 Corvette Z06 run the quarter in 11.7 seconds

We're not writing about this because it's an amazing run, we're writing about it because it appears to be the first run. Someone took a 2015 Corvette Z06 to Royal Purple Raceway in Baytown, Texas and blasted it down through the quarter mile. It's still wearing the dealer number in wax pen on the windshield and dealer plates, so this example is fresh from the mold. It's also a seven-speed manual. General Motors said the row-your-own Z06 can do the 'strip in 11.2 seconds, and they undoubtedly had a professional driver and more than one run to set that time. To have Just Some Guy show up at the raceway and do an 11.7 at 120.54 mph on his first run means we expect good things to come as Z06s get delivered to their owners. Check out the run in the video.

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.

Rumor: 2016 Chevy Volt gets 53 miles EV range, 40% increase

While we're still waiting for the official word from GM, news is creeping around the Internet that the 2016 Chevy Volt will get a big boost in all-electric range and gas-burning efficiency. According to new rumors out today, the second-gen Volt will be able to go 53 miles on a full charge, have 106 MPGe and be able to get 42 miles per gallon on the official EPA numbers. Compared to the outgoing first-gen Volt (38 miles EV range, 98 MPGe, and 37 mpg) these are all impressive increases. The all-electric range boost of almost 40 percent is the biggest surprise, though. We knew the new Volt would get better numbers than the first-gen model, but when GM debuted the car in Detroit earlier this year, it said it suspected the Volt would get a 50-mile range, 41 mpg and 102 MPGe. We'll be keeping an eye out for official confirmation of all these new numbers. Volt drivers are already making most of their driving miles electric. The number sits at about 80 percent currently, and GM has said it expects this to climb to 90 percent in the new model. GM said in May that the 2016 Volt will start at $33,995, a bit lower than the current Volt's MSRP of $34,170 before any tax breaks. So, for less money you'll be getting much better fuel economy. What's not to like about that? Preorders are already open for interested buyers in some parts of the country.
