Weekend Highlight - Drive Modes in Wet/Damp Conditions

MTI Racing's team of engineers and technicians spent some time on Nov. 22, 2013 at Atlanta Motorsports Park (AMP) to get some baseline track data on our new C7 Corvette. Unfortunately, it was raining, but we took the opportunity to test some of the driving modes on a wet/damp track.

The C7's new drive mode selector has five primary settings: Weather, Eco, Tour, Sport and Track. We tested Weather, Tour, Sport, and Tracking on track, and Eco to get there.



The official MTI Racing notes read "makes car undrivable." The delay in acceleration, used to prevent unnecessary loss of traction, makes it difficult to get anything done on track.



Eco mode deactivates 4 cylinders to make the C7... well, more economical. It raises the highway mpg up to 30 mpg, but at the cost of horsepower. Due to this lost of power in this mode, it wasn't tested on track.



This mode provides better forward traction than the Weather setting, but still very intrusive during turns. It produced heavy understeer while entering turns, and massive oversteer while exiting them.



Driving with no Traction Control in wet/damp conditions is a bad idea, but we will try anything once. Our testing confirmed that it is a bad idea. It took less than one lap to realize it was not safe.



Touring was the preferred mode for the Damp/Wet conditions. It had just the right amount of traction control to inspire confidence and safely traverse the track. It led to the highest track time by nearly 7 seconds.


In any wet/damp condition, we recommend that your first concern is safety. Never do anything that could put yourself in harms way. If you are on track in wet/damp conditions, leave it in touring and take it a little slower than normal. You will be pleased with the capabilities of the C7.
