Compared to the S63 and S65 versions of the car, the
Mercedes-Benz S560 is certainly less extreme, though not slow by any means. However, with Renntech’s ECU upgrade, the 4.0-liter
twin-turbo V8 engine, which normally makes 463 Hp and 700 Nm of
torque, or according to the tuner’s measures 484 Hp and 729 Nm of
torque, is now good for 584 Hp and 870 Nm of torque.
The flagship saloon won’t break any speed records,
but its 0 to 96 km/h acceleration time is now a respectable 4.25 sec, an
0.35 sec improvement, while the naught to 161 km/h sprint is done in
9.14 sec. As for the quarter mile, it will run it in 12.42 seconds at 188 km/h, 0.73 sec faster than the stock S560.
Renntech also has some BOV adapters available for
the W222 generation of the S560, as well as a carbon fiber-made decklid
spoiler, and new Performance Series 21-/21-inch, or 21-/22-inch wheels,
customizable with over 70 color options.
Finally, the tuner’s plug-and-play Hand-Held
Suspension Module allows users to select the desired height adjustment within
seconds. This system is said to come “without any wiring or extensive
installation”.
