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.

2016 British Grand Prix kept mostly calm and carried on

Three bursts of chaos decided the course of the British Grand Prix. The first was a literal cloudburst a dozen minutes before the race, which poured water on the Silverstone Circuit while drivers sat on the grid. Six minutes before the lights-out, the race director decided to start the race behind the Safety Car. The field loped around the wet track for five laps. When the Safety Car pulled off, the three leaders – Mercedes-AMG Petronas' Lewis Hamilton, followed by teammate Nico Rosberg and Red Bull's Max Verstappen – stayed out. Behind them, the second chaotic moment occurred: a big group of drivers made pit stops for intermediate tires. When Manor's Pascal Wehrlein spun at Turn 1 on Lap 7, officials issued a Virtual Safety Car. With the rest of the field slowed down, the three leaders ducked into the pits on Lap 8 for intermediates. The fortuitous timing meant all three drivers rejoined the track in their original positions. By Lap 9, with racing resumed, Hamilton had a 4.9-second lead on Rosberg. From that point, even as the track dried, no one bothered Hamilton during what one commentator called "a measured drive." The Brit won his home grand prix, taking the checkered flag seven seconds ahead of Rosberg. Rosberg had to earn second place on track. The German's car didn't respond well to the intermediate tires, so Verstappen excecuted an outstanding pass on Rosberg on the outside through Chapel on Lap 16. After everyone switched to slicks, Rosberg's Mercedes reclaimed its mojo and the German hunted Verstappen down, passing the Dutchman on Lap 38. The final touch of chaos happened when Rosberg's gearbox threw a tantrum on Lap 47 of the 52-lap race. Rosberg radioed his engineer, "Gearbox problem!" His engineer replied, "Affirm. Chassis default zero one. Avoid seventh gear, Nico." The race stewards allowed the engineer's first two statements, but stewards said the instruction about seventh gear contravened the rule that "the driver must drive the car alone and unaided." After the race, officials added ten seconds to Rosberg's time, demoting him to third behind Verstappen. Rosberg's is the first penalty arising from radio communication restrictions. Unsurprisingly, Mercedes will appeal. At this year's Baku race the radio controversy stemmed from engineers refusing to tell drivers what to do. Now we know what happens when the pit wall gets loose lips.

A weird end to a weird F1 season | 2016 Abu Dhabi Grand Prix recap

The 2016 Formula 1 season ended with a bang that came from a direction no one expected. Lewis Hamilton put his Mercedes-AMG Petronas on pole position and then got away clean to start the race. Teammate Nico Rosberg did the next best thing, lining up in second and following right behind Hamilton for most of the race. Other than Rosberg's wicked pass on Red Bull's Max Verstappen to retake second place on Lap 20, things stayed all quiet at the front. Come Lap 32 of the 55-lap race, however, observers began to wonder why Hamilton was driving so slow. The Brit, working every trick he could think of to win the Driver's World Championship instead of just the race, dogged it out front trying to push Rosberg back into the chasing mix of Red Bulls and Ferraris. Over the next 15 laps Hamilton's race engineer repeatedly radioed ideal lap times. Hamilton only occasionally hit the times until finally saying, "I suggest you let us race." When the one-stopping Sebastian Vettel blasted his Ferrari from sixth to third, nosing up to Rosberg's gearbox, Mercedes team honcho Paddy Lowe got on the radio to instruct Hamilton to go faster. Hamilton replied that if he wasn't going to win the championship he didn't care about winning the race. Hamilton repeatedly zoomed through the first sector to keep everyone behind, then clogged up the works through Sectors 2 and 3. The problem with his plan was that the Red Bulls in fourth and fifth couldn't get close enough to threaten the trio at the front; even if Vettel had got by Rosberg, Rosberg would still win the Championship with a third-place finish. As it happened, Rosberg finished second behind the disconsolate Hamilton. Vettel took third, followed by Red Bull drivers Verstappen and Daniel Ricciardo, then the second Ferrari piloted by Kimi Raikkonen in sixth. Nico Hulkenberg took seventh, beating Force India teammate Sergio Perez for the last time as an intra-team rivalry. Felipe Massa closed his F1 career with ninth place in a Williams chassis that he got to take home as a gift from the team. Fernando Alonso scored the final point for McLaren, a touch of sweet for the team after the bitterness of Jenson Button retiring on Lap 12 with suspension damage. Rosberg's second place earned him 385 points for the season, enough to take the World Driver's Championship from Hamilton by just five points. Some have put the title down to Rosberg's consistency, others to his car's reliability.
