Mercedes S63 AMG 4MATIC is a big, bad luxury sedan

[dropcap]T[/dropcap]he 2014 Mercedes S63 AMG 4MATIC is not just a beautiful automobile, it lays claim to being the most powerful high-performance luxury sedan on the market today.

The big new S63 has the familiar sleek Mercedes silhouette and classic AMG design features. The large upright threedimensional radiator grille marks the car as a member of the S-Class, while the front apron with the grille painted in high-gloss black holds the stylized “A” that marks it as an AMG vehicle.

Powered by AMG’s 5.5-liter 577 hp V-8 biturbo engine, the S63 delivers 664 poundfeet of torque, clocks 0-60 mph in just 3.9 seconds and registers an electronically limited top speed of 186 mph. It also sets new standards in driving dynamics, lightweight construction and efficiency.

The engine is mated to the AMG SPEEDSHIFT MCT seven-speed sports transmission with three driving modes – “C” (Controlled Efficiency), “S” (Sport) and “M” (Manual). In the comfort-oriented “C” mode the ECO Start/Stop function is active, shuts off the eight-cylinder engine when the car is at a standstill and has smooth shifting characteristics when accelerating. In the “S” and “M” modes, the engine and transmission are significantly more agile, the ECO Start/Stop function is deactivated and an open throttle results in even faster and more aggressive gearshifts.

The new S63 AMG four-door sedan is up to 220 pounds lighter than its predecessor and comes standard with the performance oriented AMG all-wheel-drive 4MATIC system for better traction and overall driving dynamics. The weight saving was achieved through the use of forged light-alloy wheels, a lightweight lithium-ion battery and an optimized AMG high-performance twopiece brake system. Also, the entire outer skin of the car — including the roof and body front end — is made of aluminum.

The AMG V-8 biturbo engine is highly efficient and fuel consumption is lower even though the engine output has been increased by 49 hp.

Some additional technical highlights are:
•Direct gasoline injection with Piezo injectors;
• Twin turbocharging;
• All-aluminum crankcase;
• Four valves per cylinder with camshaft adjustment;
• Air-to-water intercooler;
• Efficient cooling of engine oil, engine water and transmission oil;
• Lightweight composite oil pan;
• Alternator management, and
• ECO Start/Stop function.

Another interesting feature is the AMG sports exhaust system with automatic logiccontrolled exhaust flaps in both rear silencers. When the transmission is in “C” (Controlled Efficiency) mode, the flaps remain closed in most situations, and the engine sound is more understated — perfect for long trips and a comfortable ride in the rear. In “S” (Sport) and “M” (Manual) modes, the exhaust flaps open earlier and quicker and the result is a stronger, more aggressive engine sound.

The MSRP on the 2014 Mercedes S63 AMG 4MATIC is $139,500.
