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-Maybach Ultimate Luxury SUV concept shown in leaked images

Just days ago, we posted the interior teaser image Mercedes-Maybach released of its Ultimate Luxury concept due to be presented at the Beijing Motor Show. Now photos of the entire vehicle, inside and out, have leaked online courtesy of the manufacturer. Thanks to the concept's own microsite being live for a short while, we've gotten a good look of the concept. And it's not just a dressed-up GLS by any means, even if there might be a GLS platform underneath it all: It's a high-riding four door sedan with a clearly formed trunk instead of a traditional SUV shape. There's a big waterfall grille flanked by low, aggressive three-unit headlights, and the detailing is a combination of SUV cues and something a lot more luxurious. It's not easy to design a three-box sedan that's still recognizably an SUV. Inside, there's white leather and rose-gold detailing everywhere. But the big deal is the powertrain, which in the concept is all-electric. The all wheel drive is propelled with four electric motors, with a combined power output of 750 horsepower. The battery, said to be a flat underfloor design, is good for 80 kWh and an EPA range of over 200 miles, and the vehicle's top speed is limited to 250 km/h, or 155 mph. There's DC fast charging at up to 350kW, meaning that the range can be boosted by 60 miles in just five minutes, and induction charging is also available. All in all, the vehicle reminds us of the 2009 Lagonda Luxury Utility Vehicle concept, which was also created around a three-box sedan shape and also based on a Mercedes platform, GL-Class in that case. It did not yield a production version, but maybe the Vision Ultimate Luxury will.

The owner of a biodiesel company has pleaded guilty to fraud.

This allowed his company, Green Diesel, to receive renewable fuel credits and sell them to oil companies and brokers. "These crimes are a serious threat to an important program that helps combat climate change," says Cynthia Giles of the EPA.
