Max, thanks for the video link. As informative as the video was, it raises even more questions. The video states that the driver selects individual performance modes. Is this true for the Giulia? Also, it states that the Altimax system can "optionally" be combined with NIA, an integrated actuator. Giulia? It seems that this system is similar to the Haldex system that Volvo uses. That system allows for the vehicle to run in 100% 2wd (front for the Volvo) until wheel slip is detected and then it kicks-in and adds drive to the other axle. The Giulia, of course would operate in rear wheel drive (100% rear wheel drive?), until wheel slippage is detected. The video suggests that it then adds traction to the other axle in varying proportions, as conditions require. I wonder, is it capable, if conditions require, to put the car into a traction split where more than equal drive is sent to the front axle? Could a 100% front, 0% rear drive split occur? Hmm...
There is the DNA selector which pre-selects the driving mode. It adjusts the engine performance level, throttle response, active suspension, transmission interaction.
mode is All Weather for mud, snow, ice and that sort of thing.
mode is Natural for regular or normal driving, whatever that is.
mode is Dynamic. This offers the most performance in a sport type mode.
With or without the paddle shift option, the transmission can be used in a manual valve body mode in which it only shifts when the driver tells it to shift. What it does internally, I don't know.
Active suspension is an option. There is an additional control that offers more driver control for the suspension setting. I did not play with that. There is also an optional LSD (Limited Slip Differential). The Ti Performance Package
includes Active Suspension, LSD & Paddles. As a package, this is only available for the Ti. Parts of it are included with other packages, except for the LSD. The LSD is exclusive to the Ti Performance Package.
I test drove the rear wheel drive w/paddles version. The AWD (Q4) version might have more controls.
The Quad (Quadrifoglio) has an additional R mode for the DNA selector. Race mode is primarily D mode without the nannies. The base and Ti don't have R mode.
I can't really compare the Giulia to my 4C because the engine/transmission/suspension are completely different. The 4C has the DNA w/Race modes and it works well. In my short jaunt in a Quad, it was Race/manual mode. In my test drive of the Ti, it was Dynamic Manual mostly with some Dynamic Auto. It was terrific. But, I never left the asphalt and weather was ideal (warm, dry, sunny). If there was any interaction from the nannies, I never noticed, but I wasn't pushing the car THAT hard. I was on public roads in traffic.
