This heatwave of 90+ days has really showed me the difference that ambient temp has on the s2000's engine performance...I noticed a real slowdown over the last 2 days. It sort of a tradeoff though, because i can have the top down...but the engine is a little bit slower. Still lovin' my S regardless.

Since I only drive around town to run misc. errands through the week I don't notice a performance difference in the heat, but I always laugh at myself when I have to crank the a/c just to be comfortable with the top down.

 

It hit 95
