Should a 911 be anything other than six cylinder? Discuss!
The issue here is what makes a 911 a 911? I am not sure.
Clearly the current 996 has no common parts with a 911, or a 964 I think.
The engine has grown from 2.0 to 3.6, and may go to 3.8 (as it was once before on an air cooled car).
It has changed to water cooled, gained more gears, got longer, wider, with different exhausts, framless windows, different bumpers, spoilers, wings, windscreen wipers, dials, etc., and even gained four wheel drive, stability control, traction control, sat nav, air conditioning, etc.
Whilst some of these things can be removed, it is not the same car it was. It is also stiffer and faster, in general, than previous iterations.
I think if it is harder, faster and more sexily styled, then few will complain whatever route it follows. It cannot stand still.
However, it would have a different character and perhaps lose something. If the lineage was broken, then perhaps it would be free of the baggage and be able to develop and progress, although it would ruin the marketing somewhat.
Perhaps the best answer is to provide both.
If they want it to go much faster, then I guess there is a point at which the engine gets large enough to require more cylinders. From other manufacturers, it seems that around 4 litres is when 8 cylinders comes into play.
8 cylinders would (I believe, but stand to be corrected) be popular in the US.
However, whilst the US is an important market, it should not be the only consideration.
If they make a 4th model, then this can be the luxury GT car with all the trimmings, powered by a Cayenne 4.5 litre turbo, leaving the 911 to be more focussed.
I think that if they were to make the 911 focussed and keep the weight down, then the additional cylinders will not be necessary. The emphasis should be on handling and weight. Whilst it has to fulfil the role of the GT car, this cannot fully happen.
Of course there is also the requirement to be competitive in GT racing - it will need to be the configuration that meets the rules for the appropriate class.
