If true that is one advanced awd system. Seems to not be in line with the reviews I have read though. Most reviews say the awd only activates when wheelspin is detected, otherwise it is front-wheel drive. The system above sounds more like the Acura SH-AWD which helps with drivability.murcod wrote:The important bits from that previous link - in case that page is ever taken down:Drawing on more than 40 years of engineering expertise, Suzuki has developed an active all-wheel drive system designed to maximise the driving experience.
“Kizashi Sport AWD actually anticipates oversteer or understeer and can split drive to either the front or rear wheels to provide maximum driving enjoyment
“This ‘sixth sense’ makes the Kizashi Sport AWD Suzuki’s ultimate expression of driving dynamics.
“For example, when you accelerate from rest, the system detects the extra throttle input and automatically sends drive to the rear wheels to ensure a smooth, safe take-off.”
Devers said Kizashi Sport AWD inspired greater driver confidence by enabling optimum take-off, acceleration and cornering.
He explained a key element of the new i-AWD system was feedforward control, which adjusts the proportion of engine torque sent to the rear wheels according to road conditions, vehicle dynamic conditions and driver input.
The system was created by an engineering team drawing on more than 40 years’ expertise in all-wheel and four-wheel drive. It has helped them create an all-wheel drive system for the road; a system representing a new era in driving enjoyment.
“Most soft roaders and all-wheel drive systems employ a reactive system that engages all four wheels only after detecting a loss of traction.
“With the Kizashi Sport AWD, the new active handling works in partnership with ESP to ensure optimum handling levels. We call it synergetic vehicle dynamics control.”
By constantly monitoring inputs from all the ESP sensors – wheel, steering wheel, yaw and lateral g – the system can anticipate when to increase or decrease torque to the front or rear wheels and even provides counter-steering assistance.
The technology adds an extra level of driving enjoyment, while working in tandem with ESP to ensure occupant safety levels are never compromised.
In normal driving, the system is constantly monitoring data sent from all the sensors. In a standard car, excessive understeer would be countered by reducing torque to the front wheels and braking the inside front wheel to assist turn-in.
The Sport AWD uses the same data but, if the ESP threshold has not been crossed, the logic helps enhance the driving experience.
By decreasing torque to the front wheels and simultaneously increasing torque to the rear wheels, it limits understeer, helps the car turn safely and contributes to the driving experience.
In an oversteer situation, the car reduces torque to the rear wheels, increases torque to the front wheels and provides counter steering assistance.
By actively reducing excessive oversteer or understeer, it encourages a more neutral handling characteristic.
“The system was developed by Suzuki engineers with a priority on driving feel, not just its operating logic.
“Kizashi was always designed to be a driver’s car, and the Kizashi Sport AWD represents the definitive example of that philosophy.”
Devers said while the system would reward enthusiast drivers, the impressive safety systems inherent in every Kizashi ensured maximum safety for all occupants was never compromised.
i-AWD system
Power to the rear wheels is delivered via the i-AWD controller, which constantly monitors driver input and vehicle dynamic conditions to deliver the most efficient division of power.
The key delivery component is an electronically controlled wet-type multi-plate clutch coupling, in which the degree of magnetic clutch action is modulated to provide optimum traction.
The coupling is regulated with an electrical current alternating between the two and all-wheel drive modes, based on data supplied by the array of sensors including wheel, steering wheel, yaw and lateral G.
In a first for Suzuki, the transfer case features a force-fed internal lubrication system to ensure improved durability.
The AWD system can be engaged on the fly by pressing the dash-mounted switch.
On that same note I think many reviews are incorrect about the FWD/AWD switch affecting fuel economy. Interesting either way.
