I am 76 years old and my last car before I bought the Sportage Hybrid was a Honda S2000. Capable of 150+ mph and cornered like it was on rails. I only got rid of it because getting in and out became more problematic at age 73.
I take the multitude of curves on my local roads much faster than most drivers. I suspect that keeping a steadier speed, with less need to re-accelerate out of curves, helps my fuel economy.
