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.

Daimler rebuffs Geely offer to buy stake

HONG KONG/BEIJING - Daimler AG has turned down an offer from China's Geely to take a stake of up to 5 percent via a discounted share placement, as the German automaker has long been reluctant to see existing shareholdings diluted, sources with knowledge of the talks said. A stake of that size would be worth $4.5 billion at current market prices. Although Daimler declined the offer, it told Geely it was welcome to buy shares in the open market, the sources added. Carmakers in China have embarked on a flurry of dealmaking, as they scramble to boost production of electric and plug-in hybrid vehicles ahead of tough new quotas to be imposed by Beijing, which wants to reduce urban smog and lower the country's reliance on oil. People with knowledge of Geely's thinking said the company was keen to access Daimler's electric car battery technology and wanted to establish an electric car joint venture in Wuhan, the capital of Hubei province. Geely, which also owns Swedish car maker Volvo, is still hopeful it can secure a deal in some form over the coming weeks, they added. The two automakers met in Beijing in recent weeks at Geely's behest. There, the Chinese firm, formally known as Zhejiang Geely Holding Group, offered to take a stake of between 3 percent and 5 percent if Daimler would issue new shares at a discount, the sources said. It was not immediately clear what kind of discount for the shares Geely had in mind or whether Geely was interested in buying the shares on the open market. A spokesman for Geely declined to comment. A spokesman for Daimler said the company was "very happy with our shareholder structure at present", but added that it would welcome new investors with a long-term interest in the company. Shares in Daimler were up 1 percent in early Wednesday trade, in line with the broader market.DAIMLER ALREADY TIED TO BAIC, BYD Geely, which has a market value of some $32 billion, is the leading domestic brand in China with a 5 percent market share, according to an analysis by Nomura Securities. A stake of 5 percent would establish it as Daimler's third-largest shareholder behind the Kuwait Investment Authority and BlackRock, who hold 6.8 percent and 6 percent respectively, according to Reuters data.

2014 Mercedes-Benz E-Class lineup shows its freshened face

Mercedes-Benz showed us its redesigned 2014 E-Class more than a month ago, but the Detroit Auto Show finally gave us a chance to see the full family of mid-size luxury cars and wagons in the flesh. Dieter Zetsche introduced the cars, including sedan, coupe, convertible and station wagon, on stage showing the stylish new design direction.
The wagon and sedan versions (shown as the E400 Hybrid above) will go on sale this spring, while the coupe and cabriolet will hit showrooms over the summer. Check our new gallery of live shots for the entire 2014 E-Class lineup, as well as the previously released press release below.
