Here there are some AH perfomances:
Spitfire IX:
Speed sea level: better than 109-G6
Speed max best altitude: " "
Climb rate: " "
acceleration sea level: " "
acceleration best altitude: " "
Best Roll Rate: " " (all speeds)
Spitfire XIV:
Speed sea level: better than 109-G10-K4
Speed max best altitude: " "
Climb rate: " "
acceleration sea level: " "
acceleration best altitude: " "
Best Roll Rate: " " (all speeds)
All 109G6-G10 perfomances arenŽt better (neither climb-speed nor horizontal Speed) to Spits IX-XIV, so IŽll do mention of them

.
Ah, 109G10 is better than 109K4 (more light, more climb-ascent, better armamament and Horizontal speed). This is the reason why Germany developed this version, to lost the war

----------
In Spanish:
las caracteristicas del 109G6-G10 no son mejores (ni veloc. ascensional ni horizontal) que las del Spit IX-XIV, por lo que ni las menciono.
Ah, el 109G10 es mejor que el K4 (mas ligero, mejoer subida, mejor armamento y vel horizontal). Esta es la razon del desarrollo de esta version, para perder la guerra
