Cadillac ATS-V and Mercedes-AMG C63 S pitted Head to Head

Our favorite (and only) Autoblog-alum-turned-Motor Trend staffer is back with another Head to Head video, this time pitting the Cadillac ATS-V with the Mercedes-AMG C63 S. This performance machine shootout is ostensibly a way to figure out which of these new super sedans will earn the right to go toe-to-toe with the undisputed champion of its segment, the BMW M3. In reality, it's just a really good excuse to put three of the hottest sedans on the market on video at the same time... and there's certainly nothing wrong with that. Jonny Lieberman spends time in each of the two new challengers on the road, picking apart their powertrains, chassis and driving dynamics on the kinds of twisty roads drivers of these cars will relish. Then, he hands the keys off to Randy Pobst, who sort of acts as an unmasked version of a certain tame racing driver, except that he talks and has a personality. 0-60 and quarter-mile times are equated, braking performance is measured and scores are tallied before the two sport sedans end up at Willow Springs raceway. Interestingly enough, the car that proves (just slightly) faster at the race track isn't the car that wins the comparison. Curious? We're not going to spoil it for you. Check out the video, above. Then, for more action of these two machines, check out the videos just below.

Mercedes C-Class coupe spied undisguised

The closer that it gets to an official unveiling, the more camouflage the Mercedes-Benz C-Class coupe is stripping off. These latest spy shots show the two-door with a largely undisguised front end, but the rear is still concealed. In general, the C-Class coupe looks quite similar to its four-door counterpart, but the two-door wears some unique parts to make it appear a little sportier. As with the previously spied example, the designers move the side mirrors to the doors, instead of the corner of the A-pillars, and there's a single-bar grille up front. Despite the camouflage, these shots give a clear view of the model's sleeker silhouette, as well. At the rear, you can also spy the narrower, wraparound taillights to replace the squarish units on the sedan. Mercedes will reportedly debut this longer, lower take on the C-Class model line at the Frankfurt Motor Show in September, and sales in Europe will reportedly begin in December. This isn't the last variant to come along, though. Spy shots already show an AMG version of the coupe and a convertible under development. Related Video:

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.
