Just for clarity, RPM is Power Rangers set in Terminator Salvation. An evil computer virus called Venjix starts building armies to exterminate humanity, and we manage to escape into Corinth, a domed city protected by the Power Rangers. Meanwhile, everything outside becomes a Fallout style wasteland, irradiated deserts and ruins.
As if the Terminator influence were not obvious already, one of the main villian's, Teneya 7, is a brunette in dark red leather with eyes that flash red for a second, and the Black Ranger is an android, though has no idea how he came to be one.
I never saw Turbo, so I can't say if it's a remake, but... I don't really think a car theme is enough to base that on.
Also, Blue Ranger has a Scottish accent <3
