Both short and Lang (long wheelbase) versions will receive the optional update, with more engine options to follow suit during 2014.
The report also mentions that the new 9-speed ultra-efficient transmission will replace the 7 G-Tronic in the 350 CDI and the 500, though the S 400 Hybrid and the 63 AMG will keep the 7-speed.
The Mercedes-Benz S350 CDI has 258 hp and 620 Nm (457,3 lb/ft) of torque, helping the luxury car achieve 100 km/h (62 mph) in 6.8 seconds, while the top speed is limited to 250 km/h (155 mph). We suspect the 4-MATIC version will best the acceleration figures by at least one tenth of a second.
