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.

YouTube viewers prefer BMW

BMW owners sometimes get a bad rap as being snobbish, rude drivers, but according to a new study by the online marketing company ZEFR, Bimmer aficionados also have a close relationship with the brand's vehicles. With well over 4 billion YouTube views, the German automaker is the industry's king of the road online. Making the popularity even sweeter for marketers, 95 percent of those clicks are for fan videos, which represents loads of free advertising. BMW isn't the only automaker with such an extensive following. Honda comes in a close second with around 4 billion views, and Mercedes-Benz is just a little behind it. Among all brands, it's the norm for fan-made videos rather than the official ones to get the lion's share of the clicks, generally 95 percent or more. "YouTube has become a treasure trove for connecting with the right people for automakers," Dave Rosner, ZEFR marketing boss, said to Automotive News. Beyond just a popularity contest among brands, automotive videos are big business on YouTube, according to ZEFR's research. Enthusiasts are leading the way, too. Racing is by far the most-watched category with 895,000 clips generating a staggering 8.2 billion views. Classic cars are also a very hot topic with 305,000 videos getting 1.6 billion clicks. Surprisingly, when it comes to watching auto videos, sedans are most popular on YouTube with over 9 billion views, according to Automotive News. Meanwhile, SUVs, performance vehicles, and pickups were each around 3 billion or less. You can check out the full study for yourself, as a PDF, here. Related Video:

AMG could have a hybrid model on sale by 2020

European CO2 regulations are driving every carmaker to previously unthinkable solutions in order to reduce emissions. And so far those unthinkable solutions, like a turbocharged Ferrari, have been pretty good. AMG has its development eye on the year 2021, when EU regulations will include every car sold by Mercedes-Benz parent company Daimler when calculating fleet average emissions, and says that the deadline could mean a hybrid AMG by 2020. Those are the words of the company's R&D boss, Thomas Weber, to Autocar. Weber says a hybrid system right now wouldn't work only because AMG customers "wouldn't buy it." In five years, though, not only will the pressure have forced the situation, but the low-six-figure segment might also be populated by heresies like a diesel and hybrid Bentleys, and a hybrid or electric Porsche 911, to break the ice. Acceptance is coming down from the top via supercars like the McLaren P1 and Porsche 918, and up from the bottom with the near-term incorporation of electric turbos and e-boost systems. And whenever the German challengers to Tesla arrive, that will be another huge step to changing the public's mind. E-boost is what Weber said the division is looking at right now, perhaps like the kind in Mercedes' Bluetec Hybrid that employs an innocuous battery and motor. Regenerative braking would keep the battery charged. Weber said he likes it because it's proven, it's light, it's cheap, and it's already used in high-volume applications. But we would not be surprised to see a more robust implementation by the time 2020 gets here.
