The Flying Spur handles at .98 G’s, while the S8 pulls only .94 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the Flying Spur’s turning circle is 1.6 feet tighter than the S8’s (37.1 feet vs. 38.7 feet).

The Flying Spur has .9 inches more front headroom, 3.7 inches more front legroom and .2 inches more rear headroom than the S8.
