Mitsubishi released some technical details on their new Evolution X today. Although we still don't have much new information on the engine (power output remains a mystery), we do know more about their new transmission and all wheel drive system...<!--more-->
As previously reported, the new automatic transmission in the Evo X will be a dual clutch transmission not unlike that used by VW: even and odd gears will be separated on different shafts with separate clutches to optimize shift speed, efficiency, and reap other benefits such as maintaining full boost through shifts. The system will offer drivers three modes of operation: Normal, Sport, and S-Sport with S-Sport providing the most aggressive, fast shifting possible.
A Brembo sourced braking system, not unlike that of the Evo 9 returns for the Evo X, as does a similar suspension setup, albeit modified for the new platform.
The Evolution's All Wheel Drive system has been upgraded this time around, with a completely upgraded S-AWC (Super All Wheel Control) control mechanism. The system adds an Active Stability Control (ASC) feature to its already world class suite of AWD control systems including Active Yaw Control (AYC), Sport-ABS (S-ABS), and Active Center Differential (ACD).

The Active Center Differential (ACD) uses an electronically controlled multi-plate clutch to distribute torque between the front and rear wheels on the car, enabling the car to optimize its balance between traction and steering response. Although this feature isn't completely new, it was traditionally reserved for JDM Evos in earlier generations. This time around however, it will be offered in USDM spec Evolution Xs.

The Active Yaw Control (AYC) system utilizes a torque transfer mechanism in the rear axle of the car (between the rear wheels) to move engine torque between the rear wheels as necessary to optimize traction. The system also serves as a Limited Slip Differential (LSD) while cornering to prevent excessive wheel spin from the inside tire in a turn.* Like the ACD, this is another feature that has been absent from USDM-Spec Evos although it will be present in the upcoming USDM Evo X.

The ACD & AYC in the Evolution X benefit from additional sensors installed to help the car to better understand its positioning relative to where the driver wants it to go. This will then allow the computer to adjust the car's attitude to closer match the driver's true intentions.
Also benefiting from added sensors is the S-ABS anti lock braking system, which balances brake force to keep the car stable under braking, even while cornering.
The S-AWC system ties all of this together,* utilizing engine output andwheel braking to further modify vehicle attitude. S-AWC offers three modes of operation: dry (tarmac), gravel for wet or unmade surfaces, and snow for snow conditions.
Although it's an alphabet soup of tech-terms and mechanics, this is the sort of thing Mitsubishi has been developing for years, and what's behind the stellar performance we've seen in Evos prior. Judging by these upgrades, the new Evolution X will pick up right where the last ones left off...
