Mercedes-Benz Pullman Limousines S-Class w220
As with each new S-Class, the W220 brought in new innovations such as Airmatic air suspension, Active Ventilated seats (which use miniature fans in the seats to move air through perforations), keyless entry and ignition, radar-controlled Distronic cruise control system and a cylinder deactivation system (in V12 motors only) called Active Cylinder Control, which improves fuel consumption and reduces emissions. 4MATIC all wheel drive was introduced to the North American S-Class for 2002.
The W220 had many engine options unlike W126 and W140. The range started with smaller 3.2-litre 224hp V6 motor which was superceded by enlarged 3.7-litre 245hp V6 in S350. Next is 4.3-litre 279hp V8 in S430 (that one sold very well in the USA) and 5.0-litre 306hp V8 in S500. AMG prepared the S55 with 5.4-litre 367hp V8 motor which was replaced by supercharged version, producing 500PS or 493hp (469hp in American edition). The 5.5-litre V12 motor started out as 367hp but was fitted with twin-turbochargers (from Maybach engineering work), increasing its output to 500PS (or 493hp in Europe and 469hp in USA).
For one month in 2001, AMG produced S63 AMG with 6.3-litre 444hp V12 in very limited number. An undisclosed number of extremely rare S63 AMG were sold exclusively through AMG in European and Asian markets. That motor was also fitted to just two G63 AMG for the Middle Eastern customers. AMG then pushed its technological and engineering envelope to produce the successful 6.0-litre 612hp V12 motor, making S65 AMG the world's most powerful five-seat sedan. As for the diesel motors, W220 had 3.2-litre 197hp I6 diesel and 4.0-litre 250hp V8 diesel.
