RENNtech
boosts V8-550
BiTurbo
Series to new Heights
With the
newest update of their Software Upgrade for the M278 – 4.7L V8 BiTurbo,
RENNtech boosts the 550-Series to AMG Power Levels.
The RENNtech
upgraded M278 now produces 540 HP and 705 LB-FT at crank. Compared to power
numbers by Mercedes-Benz, the 550 gains up to 138 HP and 262 LB-FT. This
Software update delivers up to 10 HP and 99 LB-FT more than the previous version.
The vast
amount of increased torque across the entire RPM range gives the 550 an extra
edge to compete with AMG powered vehicles. All this without sacrificing around
town comfort and daily driver reliability.
The M278 –
550 engine is currently offered for the W222 – S Class, C217 – S CoupĂ©/Cabriolet,
C207 – E CoupĂ©/Cabriolet, C218 – CLS Class, X166 – GLS SUV and R231 – SL Class.

RENNtech software will also be shipped for the discontinued models, the W221 –
S Class, W212 – E Class, C216 – CL Class, W166 – ML Class and X166 – GL Class.
