Yeah okee dokee, but I'm still confused...
Where then does said FI V8 with circa 435-450 kW leave the turbo'd AMG V12? Redundant? Would Merc really consider dropping the V12 from the line up? Perhaps, but if they don't, then there's a distinct encroachment if not outright overlap on the part of the V8 biturbo on V12 biturbo territory.
I honestly see no reason for a turbocharged version of this engine. Not from an efficiency point of view, not for an output point of view. 700 Nm from a the 5.5 litre SC V8 was heady stuff, but it still got pulled by a naturally aspirated 5.0 litre V10 with nearly 200 Nm less. 5 speed gearing goes a long way to explaining this. Now, with the shorter 7 speed ratios of 7G-Tronic the torque deficit between 700 Nm and 630 Nm is easily made up for. Get the gear ratios for the 5 speed AMG transmission and this new 7G-Tronic box and I'll illustrate.
There has to be a logical point where Mercedes Benz say enough is enough: too many models, too many engines in my humble opinion.
