The functioning logic of all electronic systems has been optimised to obtain exactly the right level of performance for the driving conditions. You can change the character of your 4C with the touch of a finger: docile and prudent (All weather), balanced but sporty (Natural) or fast and aggressive (Dynamic). The Alfa Romeo DNA selector has offered three driving modes since 2008. On the Alfa Romeo 4C, the system has been thoroughly revised to respond to the needs of a high performance supercar.
The three existing modes have therefore been supplemented by a fourth: Alfa Race.
Alfa Race is most extreme performance mode, and is engaged by moving the mode selector to Dynamic position and holding it there for a few seconds. Alfa Race mode puts you in total control of your car under race conditions. By minimising the interventions of electronic systems, it leaves you, the driver, in complete command.
In Alfa Race mode, ESC stability control is normally deactivated and only intervenes to prevent loss of control under harsh braking. ASR is also deactivated under acceleration and braking, leaving you to control traction through the accelerator pedal alone. Alfa's Q2 differential control system, on the other hand, remains active, as it is essential to permitting fast exits from bends.
Dynamic mode configures the car to deliver great driving performance. Engine control parameters are configured to respond instantly to accelerator input and the Alfa TCT gearbox selects a rapid action program to reduce gear shift times by up to 25%. The ESC system permits a certain angle of drift and only intervenes if steering wheel position and drift angle could put the car at risk.
Natural mode is designed for everyday use. Gear shift parameters are configured for maximum comfort and smoothness. In manual mode, the Alfa TCT transmission makes up for loss of driver concentration. The Auto-Up function shifts up to the next gear when engine speed approaches the permitted limit, while the Auto-Down function shifts down as soon as engine speed falls below 1000 rpm. Finally, the Alfa Q2 differential operates in soft mode and only cuts in if one of the rear wheels suffers a significant loss of grip.
All Weather mode should be selected to ensure maximum safety under adverse weather conditions.
In All Weather mode the car responds to accelerator input very gently. The ASR system selects special engine and brake control logic and, in the event of loss of grip, modifies power to match road speed and prevent skidding that could otherwise be difficult to control.
