Mercedes CLA45 AMG Racing is ready for a spot on the grid

Mercedes-Benz trotted out its CLA45 AMG-based racer at the 2013 Frankfurt Motor Show. We first showed you the sedan in the deluge of news and reveals that precedes most good auto shows, and were blown away by the car, formally known as the CLA45 AMG Racing Series.
We were strolling by the Mercedes stand, and figured we'd pop in and take a look at the new racer and its carbon-fiber body panels, gutted interior, and race-sourced aero parts. It's a looker, both as a road car and a track weapon. It's not clear what series the CLA45 AMG will qualify for, although it does seem like a shoe-in for the World Touring Car Championship. Let us know what you think of the CLA racer down in the comments. In the meantime, we've got a full gallery of live images up top, along with the stock images that were posted last week on the Mercedes-Benz Facebook page.

SRT Viper dukes it out with Mercedes SLS Black Series in new Head 2 Head

In Episode 36 of Motor Trend's Head 2 Head, now that the Corvette ZR1 is no more, Jonny Lieberman has to look overseas to the Mercedes-Benz SLS AMG Black Series for a challenger with similar philosophy to the SRT Viper: long hood hiding a high-horsepower engine set way back, rear-wheel drive, tiny trunks. That puts the Viper's 8.4-liter V10 with 640 horsepower and 600 pound-feet of torque against the SLS AMG's 6.2-liter V8 with 622 hp and 468 lb-ft.
However, the congruences in philosophy and magnitude of numbers doesn't translate to the driving experiences of the two, which are literally and figuratively on different continents. Lieberman gets a handle on the two of them on Northern California roads, Randy Probst then finds out how, and how quickly, they can lap Laguna Seca.
They both get kudos for being improvements on their original sources, but only one of them can take the win. You can find out by watching the video below.

Range Rover versus Mercedes-Benz: Which makes a more appealing SUV?

From time to time — truth be told, all the time — the Autoblog staff enjoys a good debate on the merits and demerits of the cars and trucks we drive each week. This week, we spent some time in a brand-new Land Rover Range Rover Supercharged SUV, a model some of us think sits at the pinnacle of the luxury utility vehicle segment. Others disagree. The following is a real-life online debate that took place over the course of a few hours. Have a read, and feel free to take sides. There's a poll at the end so you can make your voice heard. Consumer Editor Jeremy Korzeniewski: Strange as it may sound, Jeremy Clarkson and I have a few things in common, most obvious of which is that we share a given name. But we also both love cars so much that we decided to turn our automotive passion into a career — with varying degrees of success, of course — and we both have come to realize over time that there's no point in trying to topple the Land Rover Range Rover as the world's best luxury off-road utility vehicle. Thing is, this universal truth isn't quite as universally shared as I think it should be. In fact, my esteemed colleague Alex Kierstein believes that Mercedes-Benz makes the most desirable four-wheel-drive off-road vehicles. He's clearly wrong, but I feel obligated to let him explain his choice, though it won't go without a rebuttal. Senior Editor Alex Kierstein: That's correct, and so am I in this regard. I'm sorry, Jeremy, but it's an irrefutable fact that Mercedes-Benz is doing the best interiors in the business now. And the interior is where you're going to spend most of your time, at least when the thing's running. The Range Rover's interior simply isn't as special, and frankly it'll be in the shop enough that you won't enjoy it. Now, stepping into pretty much any contemporary Mercedes sedan interior is a "wow" moment. They seem special — posh, exclusive, luxurious. The SUVs, all older vehicles coming due for total redesigns at some point in the future, are lagging a bit, but it's still a premium and upscale experience. Especially since performance is almost academic at this point. Anything in this class is going to be powerful, almost absurdly so. So why not go for the one that makes you feel like royalty, rather than your mechanic? JK: I just want to point out that it was you who brought reliability into this discussion.
