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.

2019 Hyundai Kona Electric First Drive Review | No compromises

The results of last week's United Nations climate study reveal that Earth's climate situation is much more dire than previously thought. Unless we do something drastic to stop pumping carbon emissions into our atmosphere, we'll do irreversible damage by 2030. It seems almost prophetic, then, that Hyundai is launching two vehicles — the hydrogen-powered Nexo FCV and an all-electric variant of the recently launched Kona crossover. The more compelling of the two is the Hyundai Kona Electric. It joins other purely battery-powered machines such as the Nissan Leaf, the Chevy Bolt and the Tesla Model 3, but the Korean automaker one-ups the competition by arriving in the form of a crossover. Americans can't get enough of them, and no other pure electric on the market offers it unless you're talking about the $83,000 Tesla Model X. The Kona EV's next closest competitor is the boxy electric Soul, and in case you didn't know, Kia's affiliate company is none other than Hyundai. In truth, the crossover moniker isn't entirely accurate. Like its internal-combustion-engined counterpart, the Kona EV doesn't really sit above regular car height. Rather than call it a compact crossover, it'd be more appropriate to label it a hatchback with some rugged-looking body cladding. The Kona Electric does, however, top nearly all of its EV rivals for cargo space, with 19.2 cubic feet. Only the Leaf tops it at 23.6 cubic feet, but the Kona's footprint is almost a foot shorter than the Nissan's. Visually, the Kona Electric is distinguished from its petrol-powered sibling by a grille-less face, replaced by an LCD readout grid pattern with the charging port neatly hidden beneath a panel on the left side. A new light bar spans the prow, connecting the upper driving lights in a digital wave pattern repeated in the lower front, side and rear skirts. It's meant to evoke the pathways in a circuit board, according to senior chief designer Chris Chapman. Inside, more differences serve to remind you that you're sitting not just at the helm of a crossover, but a shuttle to the future. An array of PRND buttons and an electronic parking brake await your instructions. Neither seemed necessary nor an improvement over the Kona classic's tried-and-true gear selector and handbrake, but there they were. The e-e-brake perhaps does permit the double-decker center console, though, the lower level meant for gadget recharging, whether via USB or Qi wireless.

Body shop manager stole over $500,000 worth of government trucks and parts

The US Department of Justice announced yesterday that the manager of a collision and restoration business in Virginia admitted he helped misappropriate and sell vehicles and parts from the State Department. Specifically, he sold 12 Chevrolet Suburbans, a Hummer, and $7,500 worth of tires and wheels. He pled guilty to charges to commit theft of government property and wire fraud. He will likely see 18 to 20 months in prison, a fine of $4,000 to $40,000, and has already agreed to pay restitution of $416,020 and asset forfeiture of the same amount. According to the Department of Justice, the body shop manager, James Ratcliffe, worked with the owner of the business and a State Department official, both unnamed, to obtain the property. It started with the wheels and tires, which were delivered and sold on two occasions, one in 2011 and another in 2012. The trucks came later, and were sold throughout 2011 and 2013. Ratcliffe and the shop owner kept most of the profits, and shared some of the leftovers with the government official. In addition to the vehicles that were sold, the government official also gave Ratcliffe a pair of Suburbans for his own personal use. The Department of Justice estimated the total value of the SUVs at $96,400. In total, the group misappropriated $512,420 worth of property. Related Video:
