M276 V6
This is a bit confusing and BenzBoost is not sure what Mercedes is doing or why they quietly introduced a new turbo M276 V6 variant without any fanfare. The new 400 models were all supposed to get the new M276 DELA 30 turbo V6. As it turns out, some of these models have an M276 DELA 35 turbo V6 which has the exact same 333 horsepower and 354 lb-ft of torque although with 3.5 liters of displacement instead of 3.0 liters.
Why the 3.5 liter variant? Mercedes has not said why. Initially everyone thought it was simply a typo but there are in fact two M276 DELA turbo motors. The 3.5 liter unit makes the same horsepower and torque but with much less boost. The DELA 35 pushes 10.2 psi to make the 333 horsepower whereas the 3.0 liter unit has a very high 26.1 psi of boost.
This means of course that the DELA 35 motor is the better tuning choice with far more headroom especially on pump gas. This raises a big question regarding the upcoming 2015 W205 C450 sport model. That model is expected to get a boost to 367 horsepower so is Mercedes further raising the boost on the 3.0 liter unit already pushing 26.1 psi from the factory or giving that model the 3.5 liter variant with a little more boost? The latter makes far more sense and makes the C450 far more appealing.
We will have to wait and see exactly what happens and if Mercedes offers any explanation but the C400 models use the M276 DELA 30 V6 whereas the facelifted CLS400 uses the M276 DELA 35 V6 which makes sense for the larger and heavier car. The E400 model though uses the 3.0 liter variant and we have no explanation for the inconsistency.
