Recharge Wrap-up: Mercedes B-Class Electric Drive is a rock star, FedEx tests electric trucks

The Mercedes-Benz B-Class Electric Drive is in a new music video for I Lived by OneRepublic. The band's singer, Ryan Tedder, has also been brought on as a brand ambassador for the German automaker. OneRepublic will also be performing the song at the Mercedes-Benz Media Night on the eve of the Paris Motor Show. No word if Mercedes plans to offer hordes of screaming teenage fans as an option package with the B-Class Electric Drive. See the video (the car shows up around the four-minute mark) or read more in the press release below. FedEx is testing converted electric delivery trucks with diesel range extenders. Looking to shrink its carbon footprint, the company has converted a handful of trucks as part of a pilot program. In addition to battery packs, each truck is equipped with diesel turbine generators (supplied by Ian Wright's company, Wrightspeed) to provide electricity when the battery is depleted. Because the diesel motors aren't powering the vehicle directly, they can continuously run at their most efficient speed, making the trucks about twice as efficient as those powered by traditional means.

The fuel economy gains depend on the particular version of the truck, but the biggest improvement will likely come from the 3.5-liter V6 and the 2.7-liter EcoBoost V-6. Automotive News predicts the F-150 SFE to be rated at 21 mpg city/28 highway/23 combined, which are identical figures to the Ram 1500 EcoDiesel. The result could be a noteworthy fuel economy battle between Ford and Ram trucks. Learn more at Automotive News. The US Department of Energy is providing $25 million in funding toward reducing the price of algal biofuels. The goal is to get the price of these renewable fuels below $5 per gasoline gallon equivalent (gge) by 2019, and less than $3 per gge by 2030. The money will fund projects to develop better algal cultures that produce biofuel and other useful bioproducts, and projects to boost biomass productivity. The DOE says it wants to help develop a "bioeconomy" that provides jobs, helps the environment and ensures energy security. Read more at Energy.gov. This content is hosted by a third party.

Buy a V8 Mercedes-Maybach, or splurge for a V12? Oh to have such problems

There's a certain air that surrounds the Maybach badge, and it's not just the scent being pumped out by the ionizer in the car's glovebox. It's the cream of the crop when it comes to German luxury. These cars are filled with an acre's worth of wood and a herd's worth of cows, ensuring your fingers rarely touch materials as pedestrian as plastic. It's as quiet, as smooth, and as imposing as you think it would be. Though the latest model from Mercedes-Maybach, the S550, might have swapped in a V8 and all-wheel drive in place of the V12 at the heart of the S600, no other amenities have been lost in translation. The car's size gives it a certain presence. Staring at the profile shows a wheelbase that spans two counties, necessitating a microphone and speaker setup simply so that the driver can converse with the passenger – and a Maybach will almost always have a passenger. No one buys a Maybach to drive. You buy a Maybach to be driven. No means of transport short of business-class airline seating offers this much space. Sit back, recline the seat, roll up the shades and enjoy your $167,125 cocoon. But you know all of that already. What you really want to know is if $25,000 - the V12-powered S600 starts at $192,225 - is worth it to gain an extra four cylinders, 74 horsepower, and 96 lb-ft of torque. On paper, no, it's not. The two cars have identical performance numbers, and the S550 benefits from Mercedes' 4Matic all-wheel-drive system. Even with all-wheel drive, the S550 weighs less than the nose-heavy S600. Fuel economy is, as expected, superior in the S550. It's rated at 16 city, 24 highway and 19 combined as opposed to 13 city, 21 highway, and 16 combined. Visually, the two cars are identical save for a few badges. The V12 badge on the S600 is replaced with a 4Matic badge on the S550, and that's where things start to get murky. When you're spending six figures on a car, decisions become more emotional than practical. $25,000 is a lot of money, but there's a bigger difference between $25,000 and $50,000 than there is between $167,000 and $192,000. As stated, you don't buy these cars to drive. Performance needs to be merely adequate. A smooth, torquey V12 is likely preferable to a hairy-chested V8, refined as it may be. These cars will never touch redline, lest the passengers spill their champagne. Plus, that V12 badge is worth its weight in country club memberships. Driving an S550 is fine until an owner shows up at an event behind an S600.

Mercedes to roll out C63 AMG late in 2014 with 4.0L V8

The new 2014 Mercedes-Benz C-Class is upon us, launching initially in North America with turbocharged four-cylinder C300 4Matic and six-cylinder C400 4Matic flavors. But that's only the tip of the proverbial iceberg when it comes to the vast array of powertrain configurations that will be offered in the new C-Class in markets around the world. Orders will soon be rolling in for gasoline, hybrid and diesel engines with four, six or eight cylinders, driving the rear wheels or all four, with the seven-speed automatic transmission soon to be replaced by a new nine-speed unit. But what enthusiasts are really looking forward to is the next C63 AMG.
As BMW has done with the M3 (and new M4), Mercedes has gradually ratcheted up the cylinder count in its AMG C-Class, graduating from the 3.6-liter V6 in the original C36 AMG to the 4.3-liter V8 in the C43 AMG, then the 5.5-liter V8 in the C55 AMG before going the distance with the sublime 6.2-liter V8 in the C63 AMG. Like its rivals, Mercedes is expected to use turbochargers as a replacement for displacement in the next model, but unlike its Bavarian rival, it won't be losing any cylinders in the process.
Skipping the 5.5-liter twin-turbo V8 that has gone on to power other AMG models, the next C63 AMG is still expected to introduce a new 4.0-liter twin-turbo V8 producing between 450 and 500 horsepower. It'll also reportedly keep the same seven-speed automatic transmission (instead of switching to the new nine-speed), but the jury's still out on whether it'll come with rear- or all-wheel drive (or offer buyers the choice). The downsized V8 - codenamed M177 - is then expected to find its way into other models, but the C-Class will be the first to get it when it arrives before the end of the new year ahead.
