This Civic Si is also lighter and stiffer than its predecessor, though Honda doesn't specify exactly by how much. Adaptive dampers with Normal and Sport settings are standard, as is a helical front limited-slip differential. The Si also shares its front upper control arms with the ultra-hardcore Civic Type R.
The seats in both vehicles were cloth. RESULTS Within 20 minutes, readings in both cars exceeded 125 F and reached a maximum stabilized temperature in 40 minutes (Figure). The temperature rise in the first 10-minute interval was more severe for the dark-colored enclosed sedan than for the light-colored minivan. The maximum stabilized temperature was also higher for the dark enclosed sedan (140 F compared to 138 F), which was a temperature rise of over 45 F in less than 1 hour.
After one hour, the average car is 43 degrees hotter than the outside temperature. After 90 minutes, the average temperature difference is 48 degrees. On a 90-degree day, that equates to 138 degreesâhigher than the hottest outdoor temperature ever recorded on earth.
