Similar to the X300 series vehicles of 1995-1997, Jaguar decided to use something that they'd never performed before in the title of sustained performance, and that has been to incorporate a supercharger to the AJ16 engine, a characteristic which remains provided to this day. By bolting on an Eaton M90 supercharger and an air to water intercooler, energy on the AJ16 six tube rose to a healthier 321bhp, and torque flower as properly to a whopping 378 lb feet which necessitated a swap to a GM 4L80E transmission to take care of the perspective that has been heading toward a corner axle.
