Having never driven a Scud I can't comment on that gear change, but the difference between the 360 and 458 gearchange is light years. I don't remember there being any close to the difference in speed/smoothness of gearchange when I drove the 430 and compared it to the 360.

The F458 has a complete different gearbox compared to the previous models. The Getrag Powershift DCT 7DCL750 is a wet 7-speed dual-clutch transmission and integrates everything including the EDiff3. It has triple cones on all gears and weights 120kg! There is no more "F1 hydraulic" pump even if the gear shifter system remains hydraulic. It has a maximum torque capacity of 750Nm.

Clutch wear is estimated being between 100K and 200K but only real usage will confirm the real clutch life on the Italia. The good thing is that the software will never allow excessive slipping like standing still uphill.

Here is a part of a Getrag document :

The new Ferrari 458 Italia is equipped with the GETRAG Powershift
7DCL750 transmission with the world-first of an active differential lock (eLSD, electronically controlled limited slip differential) integrated into a dual clutch transmission. It is actuated by the transmission electronics and the system hydraulics present in the transmission and can thus further optimize driving dynamics. The use of a planetary gear differential and a disk pack arrangement according to the shaft to shaft principle produces an extremely compact design with low clutch torques. Carbon fiber friction disks and a shared transmission oil supply guarantee a high thermal load capacity.
The differential does not need separate actuators or an ECU (electronic control unit) because the dual clutch transmission delivers the hydraulic pressure needed for actuation and the control strategy of the differential lock has been integrated into the transmission control unit.

Compared to the robotized manual gearbox of previous models (355-360-430), the Getrag gearbox is a total different unit and will never procure the "hammer" effect of the Scud.

I can't even begin to understand 20% of that but I'm impressed none the less. Thanks for posting. At least I have been fortunate enough to understand the difference it makes when in the driving seat

your very lucky is be able to drive such a machine. I sat in one a couple of weekends ago in a ferrari dealership. I loved it from just sitting in it.

if you can see yourself doing it, it is possible - mike spinner

will be a proud owner of a ferrari 360 spider
