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.

Domino's reveals Chevy Spark-based delivery car

Next time you order from Domino's Pizza, check out the delivery car. In an effort to get hot and fresh pizzas to hungry customers, the company is creating a small run of custom vehicles that are tailored for the job. Dubbed the Domino's Delivery Expert (DXP), these 2015 Chevrolet Spark-based hatchbacks pack a plethora of features to provide the perfect pie. When the DXP's on delivery duty, every order should arrive steaming hot thanks to the hatchback's biggest custom upgrade – a warming oven right behind the driver. Accessible from outside, it can keep pizzas at the perfect temperature on the way to your house and hold two of Domino's Heatwave bags. Other than the driver's seat, the rest of the interior also gets replaced with bountiful storage and non-slip surfaces. According to the company, as many as 80 pizzas could conceivably fit inside, and that would be quite a party. The exterior is still clearly derived from the Spark but with some clever additions. An illuminated "Out for Delivery" sign is on the roof, and a puddle light shoots the Domino's logo on the ground. Plus, the company's red-and-blue color scheme is emblazoned over the hood, pillars, and hatch. Underneath all the pizza-related mods, power comes from a 1.2-liter four-cylinder and CVT. Rather than just a one-off stunt, Domino's is working with Roush Enterprises and former General Motors exec Kenneth R. Baker to build 100 DXPs. They're hitting the streets in 25 US cities, and you can check if your locale is included on the project's website. The seed of this idea came from a partnership with Local Motors to crowdsource the ultimate pizza delivery platform. Domino's Launches Purpose-Built Pizza Delivery Vehicle Domino's Innovative DXP™ Created by Three Great Michigan Brands and an International Crowdsourcing Design Competition Ann Arbor, Mich., Oct. 21, 2015 -- In its latest innovation as the recognized world leader in pizza delivery, Domino's (NYSE:DPZ) is launching the Domino's DXP™ (Delivery Expert), a specially designed and built pizza delivery vehicle. The DXP is the combined brainchild of former GM R&D executive Kenneth R. Baker, Michigan-based Roush Enterprises and Domino's. To also include consumers' input, hundreds of concepts were initially identified in an online crowdsourcing design competition hosted by Local Motors. "The Domino's DXP is the first purpose-built vehicle aimed at revolutionizing pizza delivery," said Russell Weiner, president of Domino's USA.

Corvette Z06 and Viper TA square off at the strip

There are many long-standing grudge matches among automobiles: 911 vs GT-R, Mustang vs Camaro, Ferrari vs Lamborghini... but as far as high-end American metal goes, it doesn't get much more legendary than Viper vs 'Vette. So after Chevy released the new Corvette Z06, we knew it was only a matter of time before it would have to square off against the Viper TA. And what better place to pit these two parallel pillars of American performance than on the drag strip? Fortunately that's just what we have here. In one corner, the 2014 Dodge Viper TA, with its 8.4-liter V10 pumping out 640 horsepower and 600 pound-feet of torque. In the other, the 2015 Chevrolet Corvette Z06, the supercharger on its 6.2-liter V8 more than making up for the discrepancy in displacement and cylinder count to produce 650 hp and just as much torque. But numbers don't tell the whole story, so watch the video clip to see which reaches the end of the quarter-mile first.
