Other people have covered Intel's TurboBoost feature, but this reminds me of something GM did with the Cadillac Northstar V8 back in the early 90's. https://en.wikipedia.org/wiki/Northstar_engine_series https://en.wikipedia.org/wiki/Northstar_engine_series When the engine did NOT have coolant, it would run only one bank of cylinders at a time and alternate between the two to let them cool. The system was at least somewhat effective. There's a story from the time about a journalist that was testing the feature in the desert. He stopped at a truck stop after conducting the test and amazed the folks at the stop by opening the hood, filling the engine with coolant, and driving off like nothing was amiss.
