2015 Mercedes-AMG C63 S First Drive [w/video]

As I mashed the throttle heading into the back straight of a nearly three-mile-long race track, I couldn't help but center my mind on two ostensibly disparate subjects: physics and pistons. If the heart of an automobile is its engine, the heart of the engine are its rotating bits – the crankshaft, pistons and the block they're nested inside. It seems fitting, then, that the internals of the twin-turbocharged 4.0-liter V8 typify the brand-new 2015 Mercedes-AMG C63 sedan I found myself piloting in Portugal. Whereas the last C-Class AMG availed itself of a brute of an engine, employing 6.2 liters of displacement to make its 451 horsepower the old fashioned way, the latest AMG's V8 engine has been downsized radically. I had the opportunity earlier in the day to actually hold the pistons of the new 4.0 Biturbo V8 in my hands, alongside those of the outgoing 6.2. The difference in size is staggering, the new lumps looking downright picayune in comparison to the latter. These eight seemingly diminutive pistons turn combustion into crankshaft-spinning power inside a block that is smaller, lighter and more compact than I'd have thought possible, considering the prodigious output the engine spits out. I had gone into this assignment expecting to pen an ode to lost love; a sonnet of sorrow bemoaning the switch from massive cylinders to wheezing power adders. But I was wrong. In fact, the report that follows may indeed read a little like a love song, except it will heap praise not on what used to be, but instead on what is now possible. The new heart of AMG more than makes up for its reduction in size by relying on turbochargers and smart engineering to turn just 4.0 liters into 469 horsepower and 479 pound-feet of torque starting at just 1,750 rpm, or as much as 503 ponies and 516 lb-ft in uprated S guise. Foot to the floor, eyes focused on the turn ahead, a hard right-hander named Primeira that requires hard braking and quick reflexes, I had a fleeting moment of clarity: These are some hard-working pistons. A few days on the street and track in and around Faro, Portugal, has convinced me that the new Mercedes-AMG C63 is a better car in any meaningful measurement than it was before. And I'll go one step further. Not only is this the best C-Class AMG ever, it's also my new favorite in the hotly contested segment that includes such knee-benders as the BMW M3 and M4.

Recharge Wrap-up: 2015 Honda CR-Z now on sale, Daimler and Linde building hydrogen stations in Germany

The 2015 Honda CR-Z hybrid is now available at dealerships, for slightly more money. The CR-Z starts at an MSRP of $20,145 (plus $790 in destination charges), up from the $19,995 price of the 2014 model. For those who don't want to row their own gears with the six-speed manual transmission, the available CVT adds an extra $650 to the price, but also offers better fuel economy, especially in the city. The manual-equipped CR-Z gets 31 mpg city/38 highway/34 combined, while the CVT version is rated at 36/39/37 mpg. The 1.5-liter engine and electric motor provide a combined peak 130 horsepower. The manual CR-Z offers 140 pound-feet of torque, with the CVT version providing 127 pound-feet. Customers can also soup up their new CR-Z with upgrades (including a supercharger) from Honda Performance Development. Learn more in the press release below. Daimler and Linde are teaming up to build hydrogen fueling stations in Germany. The automaker and gases and engineering company, with the help of a few oil and gas companies, plan to install 13 new stations by the end of 2015. The installations precede a push by Daimler to get more fuel cell vehicles on the road. "From 2017, we are planning to bring competitively priced fuel-cell vehicles to market," says Daimler's Herbert Kohler. "So now is the time to build a nationwide fuelling infrastructure." Linde will supply the stations with fully renewable hydrogen. Read more in the press release below. In 1899, an EV set a world landspeed record, and Wired has revisited the story with a nice look back at the "La Jamais Contente" and its driver, Belgian engineer Camille Jenatzy. Jenatzy built an electric car to race in a hillclimb, which he won while clocking a top speed of 17 miles per hour (measured the old-timey way - without radar guns). Just a few weeks later, another man set a landspeed record of 32 miles per hour, beginning a back-and-forth series of setting new records. Then, on April 29, 1899, "The Red Devil," as Jenatzy became known as, surpassed 100 kph (62 mph) when his torpedo-shaped electric car set a record of 65.8 mph. It was powered by two 25-kilowatt electric motors. Read the whole story over at Wired.
