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.

GM considering new powertrain options for large SUVs

Aside from the new General Motors offerings, there's not a whole lot of action going on in the fullsize SUV segment. That doesn't seem to be stopping GM from pushing the envelope in the market as Automotive News is reporting that the automaker is looking to introduce some new powertrain options into the Chevy Tahoe (and Suburban), GMC Yukon (and Yukon XL) and the Cadillac Escalade - all have been redesigned for the 2015 model year.
Now, we already know that GM and Ford are collaborating on nine- and ten-speed transmissions for a broad range of applications (including the big SUVs), but this new report says that GM is also considering other options as a way to one-up the competition and, of course, to optimize fuel economy. AN quotes Jeff Luke, executive chief engineer for GM trucks, as saying that "interesting powertrain technologies" are coming including a return of a hybrid SUV and possibly even a diesel engine. Although it sounds like the latter could come down to how customers respond to the 2014 Jeep Grand Cherokee EcoDiesel.

2015 Cadillac Escalade gets 8-speed auto, range-topping Platinum Collection trim

The redesigned 2015 Cadillac Escalade is still quite fresh on the market, but the luxury brand has a host of mid-model-year updates for its massive luxury SUV that should make it an even better driver. The range-topping Platinum Collection (pictured above) is also all set to ensconce drivers in leather when it hits the road in the fourth quarter of 2014.
The entire Escalade range now gets an eight-speed automatic to replace the previous six-speed, and four-wheel drive models also get a two-speed transfer case to go along with it. New standard features include a Surround View camera system, 4G LTE connectivity, and the electric tailgate also now closes hands-free, in addition to opening that way.
To make riding in the Escalade an even more luxurious experience, Cadillac is adding a Platinum trim. Exterior changes add even more shine to the behemoth SUV with a grille wearing the redesigned brand crest, additional chrome trim, 22-inch wheels and Platinum badges. However, the interior is where things really get plush. The first and second row of seats are wrapped in Nappa, semi-aniline leather in a choice of either beige or gray. The dashboard, upper door panels and center console also get hand-stitched and wrapped leather, plus a suede microfiber headliner. Both front seats are heated and cooled with 18-way power adjustments, and the driver even gets a massaging function. Rear passengers are hardly left out, either, with 7-inch LCD screens in the headrests and a 9-inch screen in the center.
