Between the E170 and E175, which aircraft has the larger 180-degree turn radius?

Explanation:
In a coordinated level turn, the radius you trace depends mainly on your speed and the bank angle you use. If you keep the same bank but fly faster, the turn radius grows because the aircraft covers more airspace per degree of turn. The E175 is heavier and has a higher wing loading than the E170. To stay within safe lift and structural limits for a given maneuver, it tends to operate at a higher speed than the E170 when performing a standard 180-degree turn. Since the radius increases with speed, the E175 ends up needing a larger turning radius to complete the 180-degree turn. So, the larger 180-degree turn radius belongs to the E175.
