Hottest version yet of its C-Class lineup, the 2014 Mercedes-Benz C63 AMG "Edition 507" has just broken cover prior to making its formal public debut at the Geneva Auto Show in March. As the name implies, this latest road-rager out of the AMG stables packs a 507-horsepower V8 underhood and also boasts a host of functional go-faster enhancements complemented by unique cabin cosmetics.
Fortified heart of the new Edition 507 is a seriously tweaked version of the naturally aspirated 6.3-liter V8 found in the base C63 AMG. Topped with a titanium-gray painted variable intake manifold, it gains a new engine control system along with forged pistons from the SLS AMG, revamped connecting rods and a lighter crankshaft. Those internal revamps shed 6.6 pounds of rotational mass, which permits quicker response to throttle inputs. Collectively, the upgrades raise pony count from 451 to 507 and move peak torque up from 443 to 450 lb.-ft.
Backed by a paddle-shiftable AMG Speedshift MCT 7-speed automatic, both Coupe and Sedan versions of the Edition 507 can streak from 0-60 mph in 4.1 seconds, making them 0.3 tick quicker than a standard C63 AMG and giving each a 0.2 second advantage on models fitted with the 481-horsepower AMG Development Package. Top speed also pops from 155 mph to 174 mph. While the suspension carries over unchanged, the new C63 AMG Edition 507 does come with an even more capable AMG performance braking system. Vented and perforated all around, these super-stoppers use lighter and more robust compound-construction rotors up front and feature red-painted calipers. For the ultimate enthusiast, the "Edition 507" also will be available with an AMG locking rear differential.
Visually, the C63 AMG Edition 507 boasts a hood with dual air extractors culled from the C63 AMG Coupe Black Series and features gloss-black accenting on its decklid spoiler lip, exterior mirror housings and grille/daytime running light surrounds set off with a matte-graphite grey AMG sport-stripe applique above the rocker panels. New AMG forged light-alloy wheels in high-sheen titanium gray or matte-black are wrapped in sticky 235/35 tires up front and 255/30 rubber in the rear. In addition to four standard C63 AMG colors, the Edition 507 also will be available in an exclusive, designo magno platinum-matte finish.
The cabin of the Edition 507 gets a similar kind of recasting with three different designo interior trim choices in leather/Dinamica or full leather set off with an flat-bottom AMG Performance steering wheel, unique red-accented AMG instrument cluster, high-gloss piano black elements and an Edition 507 badge on dash. Options include AMG Performance Media and special carbon-fiber/piano black trims.
The 2014 Mercedes-Benz C63 AMG Edition 507 will arrive in the U.S. this summer. Pricing will be announced closer to its on-sale date.
