Alexis just smirked. Sakuya actively challenging her, some one firing on her from behind. "Faster eh?" Alexis replied. "Two words for ya. Trans-Am."

and as if on that command, the Stardust Radiance Exia lit up, glowing a 'divine gold' instead of the usual red you see with Trans-Am normally and tore after Sakuya, after images trailing behind the GN Drive powered Gundam for a few seconds before just leaving a trail of gold GN Particles in her wake as she closed the gap a Sakuya had formed so easily. 

"You wanna drag race? then lets go!" Alexis challenged, purging her own arm mounted weapons, and boosting the output on her GN Drive to max, causing the Condensers on her suit to glow a bit brighter.
