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.

Mercedes spent ˆ250 million to win Formula One titles last year

Success in Formula One requires skill, diligence, commitment and ingenuity. It also takes truckloads of money. In the case of Mercedes in last year's world championship, in which it took both the drivers' and constructors' titles in dominant style, those truckloads came to ˆ250 million last season alone – equivalent to over $285m in dead presidents. A report from Germany's own Auto Motor und Sport details the staggering investment that Mercedes made in order to get to the winner's circle last season. After 15 seasons with McLaren netting one constructors' and three drivers' titles, Mercedes motorsport chief Norbert Haug convinced the Daimler board late in 2009 to take over the Brawn GP team that had just won the championship. Because the team would be getting a large payout from Bernie Ecclestone as the returning champions the following year, and with sponsors lined up, Daimler only had to pony up a small portion of a smaller budget: in 2010 (its first season under the Mercedes banner), the team ran on a budget of "only" ˆ153 million ($175m). Over the course of the following seasons, though, the team's share of the TV revenues from Formula One Management went down as Mercedes struggled to climb back up the standings, but successive advocates (including Haug, Ross Brawn and Niki Lauda) successfully convinced the bean-counters in Stuttgart to ratchet up the payments. By 2012, the budget was expanded to ˆ200 million, and further climbed to ˆ250 million in 2013 and 2014. Fortunately for Daimler, the investment was starting to pay off by then as the team finished second in the constructors' standings in 2013, bringing ˆ74 million in from Ecclestone's coffers to cover roughly a third of the budget. With Malaysian oil giant Petronas alone kicking in upwards of another ˆ30 million per season as title sponsor (as of 2009 when it signed on), and untold millions more coming in from other partners, it looks like the actual cost to Daimler for securing both world titles and a winning reputation was actually more like hundred million or so.

Mercedes calling in CLS, E-Class over rubber seal fire risk

Mercedes-Benz has discovered a problem with certain E-Class and CLS-Class models and has notified the National Highway Traffic Safety Administration of a recall it's undertaking to resolve the issue. The problem is with the rubber seal at the back of the engine bay, which according to the statement below "may temporarily stick to the hood when it is opened and then may fall into the engine bay when the hood is closed." If it then comes into contact with the exhaust system, it could start a fire. And fires in the engine bay are never a good thing, unless they're contained entirely within the combustion chamber. The issue affects an estimated total of 147,224 E-Class and CLS-Class vehicles, all told, across America – including four-doors, wagons, hybrids and AMG performance models (but no E-Class coupes or convertibles) from the 2013-15 model years. To fix the problem, Benz dealers will simply need to attach four additional clips to keep the seal in place, and will start doing so midway through next month. RECALL Subject : Rubber Seal may Dislodge and Contact Exhaust Report Receipt Date: FEB 13, 2015 NHTSA Campaign Number: 15V088000 Component(s): STRUCTURE Potential Number of Units Affected: 147,224 Manufacturer: Mercedes-Benz USA, LLC. SUMMARY: Mercedes-Benz USA, LLC. (MBUSA) is recalling certain model year 2013-2015 E350 Sedan, E350 4Matic Sedan, E350 4Matic Station Wagon, E400 Hybrid Sedan, CLS 550 CGI, and CLS550 4Matic, 2013-2014 E550 4Matic Sedan, 2013 E63 Sedan, E63 Station Wagon and CLS63, 2014-2015 CLS63 4Matic, E63 4Matic Sedan, E63 4Matic Sedan "S", and E63 4Matic Station Wagon, 2015 CLS400, 2015 E400 Sedan, E400 4Matic Sedan and CLS400 4Matic and 2014 CLS63 "S". The affected vehicles have a rubber seal at the back of the engine bay that may temporarily stick to the hood when it is opened and then may fall into the engine bay when the hood is closed. CONSEQUENCE: If the rubber seal falls into the engine compartment, it may contact parts of the exhaust system, increasing the risk of a fire. REMEDY: MBUSA will notify owners, and dealers will attach four additional retaining clips to the rubber seal, free of charge. The recall is expected to begin by mid-March 2015. Owners may contact MBUSA customer service at 1-201-573-5339. MBUSA's number for this recall is 2015020001. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
