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.
The inside of the car was 68 degrees at the start of the test and climbed to between 114 and 116 degrees after one hour. The temperature was over 100 degrees at 30 minutes. photo was taken every 5 seconds over an hour and compressed at a frame rate of 20 frames per second. The temperature in the vehicle went from 68 degrees to 114-116 degrees in one hour.
