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.

Here's why automakers roll out those Texas-themed pickup trucks

Every year, automakers with a full-size truck link make a big show of the Texas State Fair, usually involving a reveal of a new model. Sometimes they show a whole new truck, and other times a special edition centered on the Lone Star state. While some people might write this off as a quirk of the industry, others might be wondering, "What's the big deal with Texas?" As it turns out, part of the big deal with Texas is big truck sales. According to Dave Sullivan, product analysis manager at AutoPacific, Texas buys more trucks than any other state in the country. It's not a small margin either. Edmunds.com, one in five trucks sold in the US are sold in Texas. The state also accounts for 15 percent of the country's large truck sales, which is more than twice that of California, the second largest truck market in America. Even when you break down sales only in Texas, trucks are a huge piece of the pie - Sullivan says that a quarter of new vehicle sales in Texas are trucks. One in five trucks sold in the US are sold in Texas. But it's not just sales that make truck builders give attention to Texas. As Sullivan explained, "Pickups are life in Texas." Both he and Hugh Milne, marketing and advertising manager for the Chevy Silverado line, said that trucks are key fixtures in Texas society, as both work trucks and luxury vehicles (or Texas Cadillacs as Milne called them). Milne said Texas is so important in the truck market that if you want to be successful in the rest of the country, "you've got to be successful in Texas." As for the State Fair, it has become a prime location for reveals in part because of the importance of the Texas market and because of how big the fair is. Milne also revealed that the State Fair also hosts its own auto show, so it's an ideal venue for a vehicle introduction. So there you have it. Why do truck builders obsess over Texas? It's because Texas obsesses over trucks. When you have one market that loves your product that much, you give it the attention it deserves.

Opel's version of the Chevy Bolt will confuse people at Paris Motor Show

Two things are now official. First, Opel will reveal the Ampera-e, or the European version of the Chevrolet Bolt, at the Paris Motor Show in October. Second, General Motors has outdone itself in brand confusion, topping the Bolt/Volt ridiculousness. Opel isn't giving a single-charge range for the Ampera-e but the company is promising a "significantly longer range" than other electric vehicles. The Bolt is estimated to have a 200-mile range on the EPA scale, so whatever the Opel achieves on the European cycle will be done with the same batteries and motor as the Chevy. Opel is also looking to appeal to the auto enthusiasts with other factoids, which are basically just Bolt stats translated into metric. For instance, the Ampera-e will be able to go 0 to 50 kilometers per hour (which is 31 miles per hour to us Americans, but we're talking Europe here) in just 3.2 seconds. And for those looking to stay connected, as many as seven mobile devices can attached to the car's wireless hot spot. GM said in February that the European of the Bolt would be available across the pond next year, so the most recent bit of news isn't shocking. Still, General Motors continues to create confusion between all-electric Bolt and the extended-range plug-in Volt. It's already been reported that the Korean symbol and pronunciation of what is "B" in English is identical to the English "V," meaning that there is no difference between "Bolt" and "Volt" in that country (though there are no plans to sell the Bolt in South Korea as of yet). Now, in Europe, they're taking the name they used to use for the European of the Volt — Ampera — and merely adding an "-e" at the end of it. For those looking to be less confused, take a look at Opel's press release here.
