There are some letters that, when combined, carry a certain significance. Say the letters AMG to anyone who's ever driven (or for that matter even seen) a performance-oriented Mercedes-Benz and you're bound to elicit shivers. Founded as an independent customizing company, but part of the German automaker since the 1990s, AMG crafts some of the most venerable performance luxury automobiles ever to speed along road or track. Now the Affalterbach-based speed demons have released a series of new products.

First up we have the new E63 AMG. Based on the latest update to the Mercedes-Benz E-Class, the new E63 offers unsurpassed levels of power and pace with the versatility and luxury of a four-door sedan. Under the hood smoulders a 5.5-liter twin-turbo V8 engine with 557 horsepower for a 4.2-second 0-62 time, or (for the first time) a new S-Model with 585 horsepower that propels it to 62 in a quoted 3.7 seconds. Another first is the availability of 4Matic all-wheel drive. European buyers will also be able to specify a wagon version in addition to the four-door sedan.
Along with the new E63, AMG has performed similar updates to its even sexier counterpart, the CLS63. The four-door performance coupe has been treated to the same 5.5-liter twin-turbo V8 in 557- and 585-horsepower guised as the aforementioned E63, but propelling an even sleeker four-door coupe or five-door Shooting Brake body-style.
AMG's credentials extend beyond its V8 engine, though. With buyers clamoring for smaller, more nimble and more environmentally-conscious forms of transportation that don't skimp on the muscle, Mercedes-AMG is launching a fresh line of performance models packing a new 2.0-liter turbocharged four-cylinder engine that, with 360 horsepower and 332 lb-ft of torque, is claimed to be the most potent of its kind. The first model to receive the new engine, which is mated to a seven-speed dual-clutch transmission and 4Matic all-wheel drive, will be the new A45 AMG, a premium hot hatchback that looks poised to redefine the segment.
While the A45 won't be making the transatlantic journey to American showrooms, the developments that make it as fast as it is will appear in other forms. One of those will be the CLA45 AMG, a smaller take on the CLS in four-door coupe form. A CLA Shooting Brake is slated to follow, a new GLA crossover is being developed by Mercedes-Benz that's expected to receive the same treatment, and an SLA roadster is also said to be in the works.
Combined with the SLS supercar and AMG versions of the C, S, SL, SLK, ML, GL, G and CL-Class models, these new high-speed luxury automobiles promise to deliver everything that the automotive enthusiast of means could possibly desire.
