Race Tools has introduced the first tuning program for the 2014 Mercedes S-Class.

The S 350 BlueTEC can be equipped with an optimized ECU which enables the 3.0-liter V6 diesel engine to produce 300 HP (220 kW) and 670 Nm (494 lb-ft) of torque - an increase of 42 HP (30 kW) and 50 Nm (37 lb-ft) of torque.

The S500, on the other hand, can be equipped with one of two different packages. The €597 CR plug-in module enables the 4.7-liter V8 engine to develop 491 HP (361 kW) and 780 Nm (575 lb-ft) of torque - an improvement of 35 HP (26 kW) and 80 Nm (59 lb-ft). Moving up to the €1,537 version cranks up the output to 516 HP (379 kW) and 800 Nm (590 lb-ft) of torque - an increase of 60 HP (44 kW) and 100 Nm (73 lb-ft) of torque. Detailed performance specifications were not released, but this package also raises the top speed to 297 km/h (185 mph).

The performance accessories will go on sale this weekend and be available to international customers.
