MSR system (engine drive regulation)
This is an integral part of the ASR system that, in the
event of sudden gear shifting on hills, cuts in to provide
torque to the engine, thus preventing excessive driving
wheel drag that, especially in poor grip conditions, can
lead to loss of stability.
TTC system (self-locking differential effect)
The TTC system uses the braking system to produce
a behaviour similar to a limited slip differential.
The front braking system, during acceleration while
cornering, acts on the inner wheel, increasing the drive
of the outer wheel (with more load) and distributing the
torque between the front drive wheels dynamically and
continuously according to the driving conditions and the
road surface.
In this way, the system allows particularly effective and
sporty driving to be achieved.
The TTC system intervenes activating the Sport driving
mode of the “Manettino Abarth” system (see the
“Manettino Abarth car dynamic control system (DSS
– Driving Sport Switch)” paragraph in this section).
When the TTC system is active, the ASR system
calibration is changed and made less intrusive.
Do not take unnecessary risks, even if
your vehicle is fitted with this system.
Your driving style must always be suited to the
road conditions, visibility and traffic.
The driver is always responsible for road safety.
WARNING
When travelling on snowy roads with snow chains, it
may be helpful to have the ASR system less intrusive
(activating the Sport driving mode): in these conditions,
the slipping of the drive wheels when setting off makes it
possible to have better traction.
