Mercedes A45 AMG in downhill battle with slipstream skateboarder

We're told it takes "performance, control and expression" to pilot a longboard skateboard down a mountain road, and that those happen to be the same values embodied in the Mercedes-Benz A45 AMG. That's how the two came to be combined in a black-and-white short film called Silver Slipstream.
There's no talking, no engine note and no color, just some music, a 'boarder and a car on a long cruise down the Franschhoek Pass in the Western Cape of South Africa." Despite that, it's actually a pretty entertaining video of the latest Mercedes-Benz hot hatch married with extreme sports. You can watch how it all goes down in the video below.

Test drive the Mercedes SLS AMG Electric Drive with Chris Harris

It's hard to not like the Mercedes-Benz SLS AMG GT. The all-aluminum coupe is fitted with a wonderful naturally aspirated 6.2-liter V8 delivering 583 horsepower and 479 pound-feet of torque. Not only does the burly combustion engine launch the two-seater to 60 miles per hour in less than four seconds, but it does so with one of the world's greatest exhaust soundtracks as it roars, burbles and cackles down the road.
But what happens when Mercedes-Benz takes away the V8 and its accompanying fire-burning song? Stripped of one of its most appealing assets, does the SLS lose its soul?
Chris Harris recently had the opportunity to take the Mercedes-Benz SLS AMG Electric Drive for a track spin in Europe. Sans gasoline, but with four electric motors providing a combined 740 horsepower (737 pound-feet of torque), all-electric all-wheel drive coupe uses sophisticated torque vectoring and a multi-mode operating system to put oversteer - drifting! - back into the equation. Fun? You bet. See for yourself, below.

Recharge Wrap-up: Volvo's efficient truck concept, Tesla's updated mobile charger is cheaper

Mercedes-Benz plans to equip its gasoline-powered cars with particulate emissions filters, just like its diesel vehicles. Claiming to be the first automaker to apply the technology to gasoline motors, successful testing in the S500 led to the decision to expand the use of these filters. This announcement coincides with a $3.35 billion investment in clean diesel technology, including a new four-cylinder engine that adheres to strict emissions guidelines. It's not clear when Mercedes will begin including the filters on its gasoline vehicles, or if it intends to use them outside of Europe. Read more at Green Car Reports. Tesla has updated its mobile charger and given it a lower price. The 40-amp "Mobile Connector Bundle" – which used to sell for $650 – is now priced at $550 with two adapters and a storage bag, with an available $520 version offered without the adapters. Tesla's product description reads, "The Corded Mobile Connector has an integrated 240 volt 50 amp rated plug for high power output. A seamless design provides a low profile connection, allowing for use with covered outdoor outlets." Read more at Electrek. Volvo has developed a new truck concept that reduces fuel consumption by more than 30 percent. The modified Volvo FH 420 long-haul truck, simply called the Volvo Concept Truck, features 40 percent better aerodynamic efficiency, a weight reduction of about 4,400 pounds, and tires with lower rolling resistance. The truck's rear view mirrors have been replaced by cameras, which, in addition to reducing drag, also improve safety through better visibility. While the research vehicle won't reach market as-is, some of its aerodynamic features have already been included in real-world applications, with more to come as Volvo aims to improve the efficiency of its trucks by 50 percent. Read more at Green Car Congress, and in the press release below. Volvo Trucks' new concept truck cuts fuel consumption by more than 30% Almost one-third lower fuel consumption. Volvo Trucks' new concept vehicle shows how it is possible to drastically boost productivity in long-haul operations. Among the secrets behind these remarkable fuel savings are aerodynamic design and lower kerb weight. With support from the Swedish Energy Agency, Volvo Trucks has developed a new concept vehicle, the Volvo Concept Truck. It is the result of a five year long research project aimed at creating more energy-efficient vehicles.
