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.

Second part of Forza Horizon 3 car list revealed early

We previously brought you the first portion of Forza Horizon 3's list of 350 cars last week, and today we're bringing you part two. Apparently Fairfax Media in Australia had the list and images early and published them on The Sydney Morning Herald's website . We say early because the publication's story reveals that Playground Games, the developer of the game, plans to make the official announcement on the Forza website this Wednesday. This set of virtual machinery brings us closer to the full list, which will continue to be revealed over the coming weeks. While this part is smaller than the first one, it still features a number of notable automobiles, including the Bugatti EB110 Super Sport, GMC Syclone and Ferrari Dino 246 GT. This list also adds more vintage Aussie machines, including the very cool 1974 Holden "Sandman" HQ panel truck. Fans of the Mad Max movies may remember Max's Sandman truck from the original film. Check out the list of new cars from The Sydney Morning Herald below and take at look their article for new images and insight on what the developers' goals were for the game. 2007 Alfa Romeo 8C Competizione 1970 AMC Rebel "The Machine" 1998 Aston Martin V8 Vantage V600 2011 Audi RS 5 Coupe 2011 BMW X5 M 1981 BMW M1 1992 Bugatti EB110 Super Sport 1970 Chevrolet Corvette ZR-1 1966 Chevrolet Nova Super Sport 2008 Dodge Viper SRT10 ACR 1969 Ferrari Dino 246 GT 1968 Ferrari 365 GTB/4 2011 Ferrari FF 1978 Ford Mustang II King Cobra 1956 Ford F-100 1991 GMC Syclone 2016 Holden Special Vehicles GTS Maloo 1951 Holden 50-2106 FX Ute 1974 Holden Sandman HQ panel van 2012 Infiniti IPL G Coupe 2015 Jaguar XFR-S 1997 Lamborghini Diablo SV 2014 Lamborghini Urus 2014 Land Rover Range Rover Supercharged 2005 Lotus Elise 111S 2013 Mazda MX-5 1990 Mercedes-Benz 190E 2.5-16 Evolution II 2013 Mercedes-Benz E 63 AMG 1999 Mitsubishi Lancer Evolution VI GSR 2008 Mitsubishi Lancer Evolution X GSR 2000 Nissan Silvia Spec-R 1977 Pontiac Firebird Trans Am 2010 Renault Megane RS 250 2008 Subaru Impreza WRX STi Related Video: News Source: The Sydney Morning HeraldImage Credit: Playground Games/Microsoft Auto News Bugatti Ford GMC Holden Technology video games forza motorsport forza horizon 3
