Mercedes-Benz A45 AMG shows up to fight the hottest hatches [w/videos]

Fun coincidence. On the same day that Audi announces the unveiling of its new S3 Sportback at the Geneva Motor Show, Mercedes-Benz steals the spotlight by confirming that the all-new A45 AMG will also receive its official debut early next month. Starting life as the entry-level A-Class hatchback, the A45 AMG gets the full AMG treatment, which includes numerous performance, handling and styling upgrades.
Under the hood sits an AMG-tuned 2.0-liter turbocharged I4 breathing through a sport exhaust system helping the five-door produce 360 horsepower and 332 pound-feet of torque. This engine is paired to a seven-speed AMG dual-clutch transmission and power is sent to the ground using 4Matic all-wheel drive. Mercedes-Benz says that the A45 AMG will be able to accelerate from 0-60 miles per hour in under 4.5 seconds and it will have a top speed of 155 mph; in the land of hot hatches, it doesn't get much hotter than that. For added performance and handling, AMG has retuned the A-Class' suspension and steering systems and equipped The A45 with a three-stage stability control system that is specific to this car.
Surprisingly, the exterior styling of the A-Class was already sporty enough that the new model doesn't receive too many changes to become the A45 AMG. The biggest alterations include black accents to the chin spoiler, rocker panels and mirror caps, black wheels with red-painted brake calipers and rectangular dual exhaust outlets. Inside, it doesn't take a trained eye to spot the differences. The flat-bottomed sport steering wheel and the numerous red accents throughout the cabin (including the seatbelts!) really help to make this AMG interior stand out; front passengers will also get sport bucket seats that appear to be more than supportive enough for even the most spirited driving conditions.

Race recap: 2016 Monaco Grand Prix gets very wet, a little wild

More than at any other race, the Monaco Grand Prix question is: which combination of demolition derby, Safety Cars, and bad pit strategy will decide the podium? Last year Lewis Hamilton's late, confounding pit stop cost him victory. The year before, Nico Rosberg's qualifying "mistake" put him on pole and Mercedes-AMG Petronas' pit strategy sealed his win – good for Nico, bad for Hamilton and the rest of the field. In 2013 Hamilton dropped from second to fourth when he lollygagged in the pits. In all three years, Rosberg won. The new X factor for 2016: a Red Bull resurgence that helped Daniel Ricciardo clinch his first career pole. Nevertheless, bad pit strategy had its say in the results. Ricciardo built up a 13-second lead by Lap 15 in spite of heavy rains that forced the Safety Car to lead the first eight laps of the race. Ricciardo stopped on Lap 23 to switch to intermediate tires for the drying track, ceding the lead to Hamilton. Hamilton pitted from the lead on Lap 31 for softs, then Red Bull pulled Ricciardo in again on Lap 32 and made a snap decision to put him on ultra softs, but the tires weren't ready when Ricciardo reached his pit box. What should have been a three-second pit stop turned into a 13.6-second pit stop. Ricciardo left the pits as Hamilton came down the straight and the Aussie lost the lead into the first corner. Despite two attempts to pass later in the race, Hamilton finished first, the Aussie second. It's the second race in a row where pit strategy cost Ricciardo a near-certain win. Conversely, Force India nailed both tire strategy and pit timing with Sergio Perez. The Mexican started in eighth but got into third before half the race was done, passing four cars in the pits, and finished on the podium's final step. Otherwise the order barely changed from about half distance, with Ferrari driver Sebatian Vettel in fourth, followed by Fernando Alonso in the McLaren, Nico Hulkenberg in the second Force India, Rosberg in the second Mercedes, Carlos Sainz for Toro Rosso, Jenson Button in the second McLaren, and Felipe Massa taking the final point for tenth for Williams. Storms didn't only hover over the area, though – dark clouds hung around several teams and drivers. Mercedes' reliability is no longer so reliable. The Silver Arrows suffered engine issues on both cars in qualifying, and Hamilton's problem almost kept him from setting a time in Q3.

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.
