11 vehicles from Barrett-Jackson Las Vegas worth watching

This weekend will see the world's collector car crowds descend on Las Vegas, NV for one of the biggest shows on Barrett-Jackson's popular auction circuit. There are hundreds of vehicles up for bidding, ranging from a brand-new Lamborghini Aventador to a spattering of Art Deco classics and a huge swath of classic muscle cars.
While it's virtually impossible to assemble an inarguable list of the best cars coming during the three-day, 700-plus vehicle auction, we've sifted through the listings for this year's show - it was a tough assignment, we promise - and assembled a list of what we think will be some of the most interesting lots. We'll admit, it's a bit heavy on American iron, but if you browse BJ's listings, you'll come to a similar conclusion. Still, scroll down for our list of what we think will be the most interesting vehicles at the upcoming auction.

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.

Car theft skyrockets thanks to rising parts prices

Cars and trucks today have achieved a high level of average quality, with safety and technology features that keep occupants safer than ever and meet consumers' high expectations. But the National Insurance Crime Bureau finds that those components come with a rising price tag, leading to expensive repair bills — and rising vehicle thefts to support a thriving black market for parts. The nonprofit NICB said it looked at the cost of replacement parts for the top 10 stolen 2016 models, with average OEM part prices pulled from a database of more than 24 million vehicle damage appraisals generated for 2016 and 2017 insurance claims. The list did not include major components like engines or transmissions, only easily-stripped components like bumpers, doors, hoods and headlights. It found that: The 2016 Toyota Camry, which had a used market value of around $15,000, had 15 commonly replaced parts that added up to almost $11,000, not including labor, with quarter panels alone costing almost $1,600 a pair and a set of alloy wheels tallying more than $1,600. The Camry was also the top stolen vehicle in 2016 at 1,113 thefts. A 2016 Nissan Altima had 14 standard parts worth more than $14,000, including a single headlamp assembly that costs just over $1,000. The Altima was the second-top stolen vehicle in 2016 at 1,063 vehicles stolen. And the 2016 GMC Sierra pickup, which was No. 7 on the 2016 top-stolen list, rang up $21,000 from 20 standard components, including an $1,100 headlamp assembly and an $1,100 rear bumper. "For the professional theft ring, stealing and stripping vehicles for parts has always been a lucrative business," Jim Schweitzer, NICB's senior vice president and chief operating officer, said in a statement. "On today's cars and trucks, the parts are often worth more than the intact vehicle and may be easier to move and sell. That's why we see so many thefts of key items like wheels and tires and tailgates ... there's always a market for them." Check out the NICB infographic below. Vehicle thefts in the U.S. rose by more than 4 percent in 2017, based on preliminary FBI data, after rising 7.6 percent in 2016, though the overall trend has been down since vehicle thefts peaked in 1991, according to the NICB.
