Another distinguishing feature is the speed-sensitive power steering with rack-and-pinion steering gear: the power assistance is implemented electrohydraulically rather than just hydraulically.
Yes, it does have an electrically assisted rack-and-pinion steering, and no, the steering isn't the telepathic rudder that the Porsche 911's is, but still, it's pretty awesome.
Other advances included rubber cone independent suspension, designed by Alex Moulton (who incidentally, went on to design the Moulton bicycle -- another of my favorite designs), rack and pinion steering and a monocoque body that eliminated the need for a costly separate chassis.
