Re: 1000HP V16 Ride
this taken from an article on displacement on demand:
....This concept is not new. GM tried it 21 years ago. Some may remember the Cadillac 4-6-8 V8 engine introduced in 1981. This engine ran on 4,6 or 8 cylinders as loads demanded, but it was limited by a cable throttle, mechanically controlled transmission and a fraction of the computer power currently available. While the concept was fine, the technology wasn't. The Cadillac engine was rough and sometimes erratic when switching the number of operating cylinders. Most of these cars had their engines soon converted to work on eight cylinders all the time.
So yes, they did do this before. But obviously more primative.
