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.

Cadillac considering more engines, Vsport model for Escalade

Want to roll in the latest Cadillac Escalade? You can get it with a 6.2-liter V8... or a 6.2-liter V8. Cadillac only offers the one engine option. But that may soon change.
According to the latest from Automotive News, Cadillac is contemplating a couple of new powertrain options for its blingin' big ute. The report suggests a twin-turbo V6 and a V6 turbodiesel could be offered, and that Cadillac could create a Vsport version of the Escalade like it offers on the new CTS sedan.
The more diverse engine offerings would help attract buyers from the new Lincoln Navigator, its prime competitor, which switched from a 5.4-liter V8 this year to a 3.5-liter twin-turbo V6. The turbo V6 engines (both gasoline and diesel) would also help Cadillac market the Escalade overseas - particularly in Europe, where higher fuel prices preclude the prospect of driving a big V8 SUV for many buyers. Escalade sales have dropped from 35-40k units in the mid-2000s to around 12,000 the past couple of years.

GM recalls Chevy Impala, Cadillac XTS for braking problem

Back in April, General Motors launched an investigation into braking issues affecting the 2014 Chevy Impala. Now there's a recall of both the Impala and the Cadillac XTS with which it shares its Epsilon II platform.
The issue apparently revolves around the electronic parking brake, which may not properly disengage. As a result, the rear brake pads could rub the rotor even while the vehicle is in motion, causing "significant heat, smoke and sparks." The earlier investigation had been launched following a complaint regarding the forward collision avoidance system, which is now either appears to have been unrelated or possibly a symptom of this larger issue.
The recall affects 2013-15 XTS models manufactured between February 14, 2012, and August 22, 2014, as well as 2014-15 Impalas manufactured between January 15, 2013, and August 22, 2014. The total number of affected vehicles reported by the National Highway Traffic Safety Administration comes to precisely 132,921 units, while The Detroit News reports a higher total of 205,000 units - the difference potentially coming down to the scope within the US and more broadly across North America. Dealers will contact owners to update the software in order to fix the problem.
