CVT in a Corvette: Best or Worst Idea Ever?
We — well, most of us — have warmed up to the 8-speed automatic in the C7 Corvette. We prefer manual, but realize the automatic is quick, and the higher number of ratios keeps the engine in its sweet spot. In addition, it gets wonderful fuel mileage. Winning all around. In those exact areas of measurement, a CVT is arguably better.
We’ll wait for the groaning to stop. I know what you’re thinking: CVT transmissions are made out of the lost hopes and dreams of people who buy economy cars. However, Engineering Explained proposes a valid argument on their behalf. The points are centered around the limiting factor of fixed gear ratios and an engine’s power-band. Technically, there’s only one point where an engine is at its peak power. Some engines have a peak powerband, so all acceleration and RPM use before and after that is inherently inefficient. This allows the transmission to make the adjustments around a fixed engine RPM.
There’s not even the slightest hint that the Corvette will come with a CVT, because problems still persist. Physically, a CVT transmission isn’t really great with high torque applications. And there’s public opinion to deal with. Just tell a Corvette enthusiast that their car would be better with a CVT, and tell me what happens.
