A "Super LSD" according to Mazda LOL...

Quote:SOPHISTICATED TORQUE MANAGEMENT

To increase drivability and minimize torque steer and wheel spin in what is a very powerful front-wheel drive car, a sophisticated torque-management system combines with equal-length hardened driveshafts and a cone-type Super LSD limited slip differential.


Under the watchful eye of an advanced powertrain control module (PCM), the waste-gate bleeds off excess boost to control the torque spikes in first and second gear that would result in wheel spin, providing full boost only in third gear and above. Also, because the throttle is a drive-by-wire system, the PCM can control how quickly the throttle body reacts to driver inputs, smoothing intake volume to further minimize torque spikes. This results in different torque characteristics in first, second and third (and above) gears, minimizing torque-steer and wheel-spin and maximizing traction and acceleration.


Torque control is also linked to the steering angle, limiting power delivery when the front wheels are turned. A Super LSD cone-type limited-slip differential also minimizes wheel-spin on the inner wheel during hard cornering for smooth, predictable power delivery. Mazda also fits a similar Super LSD unit to the rotary-powered RX-8 sports car and the high-performance MAZDASPEED6 sport sedan.
