Per il momento ho un'UNICA domanda per il dott. Consalvo:
per quale motivo è stato deciso di fare un passo indietro sulla MiTo adottando il cambio C510.5 (a 5 marce) anzichè l'M32 (a 6 marce) già presente sulle precedenti motorizzazioni?
Mi riferisco all'involuzione della 1.4 TB MultiAir 135cv e soprattutto della 1.3 JTDm 90/95cv, mototizzazione che rappresenta più del 25% degli ordini per Alfa Romeo MiTo.
A parte la riduzione del numero di marce, viene universalmente contestato (da tutti) la gommosità degli innesti e che alcune marce che non entrano. Su tutti, l'estrema difficoltà ad inserire la 2° marcia in scalata che costringe a percorrere curve in folle.
Grazie mille per l'eventuale risposta.

At the moment I have one question only for mr. Consalvo.
Why you decided to take a step back on the MiTo with the change of gearbox passing to C510.5 (5 speed), instead of the M32 (6-speed) already present on the previous engines?
I refer to involution for the 1.4 TB Multiair 135cv and especially for the 1.3 JTDM 90/95cv which represents more than 25% of orders for Alfa Romeo MiTo.
Apart the reduction of the number of gears, it's widely contested (from all) the gumminess of the grafts and that some gears don't enter. Over all, it is extremely difficult to insert the 2nd when you gear down: that forces you to take corners with neutral.

Going back to the technical questions, you are asking why we have the 5 speed gearbox on some engine versions of the MiTo.
This is due to the quick response allowed by the engines. In particular, the 1.4 Multiair Turbo allows to exploit at the best the torque performance at low revs, thanks to the direct management of the throttles and the small size of the turbine.
By the way, a 6 speed gearbox, if not needed, in some cases can have a negative impact. For instance, in the 0-100 km/h you could need an additional gearshift, making a worst result in terms of performance.
About quality and feeling of the gearshift, we know about this and we are working to restore the standard levels, in terms of quality and feeling.
