Had a 4.2 when they came out, long since sold been thinking about another one but a 4.7 this time can some one please explain the difference between 4.7 / 4.7 s and mc shift.

I have seen several cars described as 's' with 4 exhausts I though the s had oval exhaust.

I only ask as I see one regularly that sounds amazing, compared to my old one and I think it has oval exhausts.

Thanks

the S is either available as an auto or f1 manual box. the MC shift f1 box has the extreme oval exhaust the S auto has a tamer system.

As Andy said the MC shift has oval tailpipes. The Auto has quad round tailpipes as per your old 4.2. The car you hear regularly is more than like a MC shift - one of the best V8 sounds on the road (once the sports buttons pressed)

So is the 4.7 with round pipes the same noise as the 4.2 with round pipes ?

Ie do I need to be looking for ones with oval pipes ?

it goes like this:

do you want the noise yes/no

do you want full auto yes/no

if yes to both you want the S AUTO with sportpack (4k extra)

then you have the proper auto box and the noise and the boot spoiler.

if you want the F1 box then any MC shift S car from launch (2008?) will suffice

I may be wrong (I often am), but I was under the impression that in the MC Shift the sport button opens the valves regardless of rpm, whereas the Automatic's valves only open above 3000 RPM when in sport mode. Having been in both i found the Automatic to sound particularly muted, compared the MC Shift, when they are both in sport mode. This is particularly apparent upon start up. Also the MC Shift felt a lot torquier.

To clarify.

4.7 S Auto has a tourque converter and is a 6 peed full auto gearbox. You can use the paddles but it is still an auto

4.7S (which is also called an MC Shift) is an automated manual gearbox out of the Ferrari 599. You can use it in an auto mode but you can feel the gear change as it happens. Once the gearbox has warmed up it will change gears in manual mode with sport activated in 100 milliseconds with 80% load on accelerator and over 5000 revs.

The other differences are that the MC Shift does not have skyhook suspension as standard but does have an extra 10bhp over the auto. It also has body kit, sports exhaust and black front light surround, plus Alcantara seats and steering wheel as standard trim.

Thee is now a sport option for th e auto car which incorporates the sports exhaust body kit and a tweeked gearchange to make it more sport so you have the best of both worlds ( the sound and quick gear change but with an auto box)

The 4.7s Auto in Sports mode opens valves after 3000rpm unlike the 4.2 - The sound is louder but not as loud as an MC Shift.

The Grancabrio is the same.

I have a 4.7s auto sports pack and would offer the following - which is based on my dealers knowledge so could be wrong!

The auto box can have MC shift added as an extra (as it is in the sport pack) and is available in sports mode if you get the revs right.

The oval exhausts are an extra included in the sports pack.

The result is three levels of noise

Auto mmm

Auto Sports mmmmmmmm

And

Manual Sport - OMG mmmmmmm

Maserati do not make this easy as there are so many options to tailor your car. Most of what has been said is correct but, whichever gearbox you have, the 4.7 GT has 440PS. You only get the extra 10PS on the Stradale which is two seater stripped out car.

The F1 gearbox 4.7 has been out since autumn 08 and the full auto since early summer 09. Yes, you can get the oval exhausts and faster gear shifts in sport mode on the auto as part of the sports pack but this has only been offered on cars built since September this year.

On the full auto, the valves in the exhaust only open above 3k revs in sport mode whereas on the F1 car (or the full auto with the sports pack) they are always open in sport mode. Interestingly, in the US, the full auto 4.7 had oval exhausts for its first two years but now has four round pipes.

Two other thoughts:
-you have always been able to get the full auto 4.7 with the red esse pack which adds the spoiler, skirts and a few other body mods from the F1 car but it still keeps the four round pipes; and
-formula dynamics in the US offer a kit to control the valves with a plip exactly as you see fit - valves closed in sport mode, open in normal mode etc. I am thinking of buying it but would be happy for someone to guinea pig it first!

Confused?

PS Your choice should be based on your gearbox preference as you can retro the exhaust to get what you want in that regard but the gearboxes are materially different. The auto is smoother but longer geared and the F1 is punchier but drinks more and is less smooth (plus has a clutch which will fail at some stage). No wrong choice.

Is there any wonder I am confused !!!!

I am going to drive both, suspect I want the auto 4.7 with sports pack and aero pack (red esse) or what ever its called.

Basically a mc shift without the f1 box.

Or if not a 4.7 with a capristo or similar if such anything exists for the gt

The worst bit and probably the hardest bit is that ideally I would like a 2 year old but sure I will have to compromise somewhere

Thanks for all the advice
