Detour is a yellow Chevrolet Corvette Indy sports car. If we carry on our Sports Car Patrol = Stunticons analogy then he'd be Dragstrip on the tenuous grounds that they're both yellow.
TF: Fold the rear of the car back to become the legs. Fold the bonnet down to become the chest. Stand.
The robot mode reveals the pale blue also used on this mould on the head & upper legs - it's also used for the body under the fold down chest. Standard Micromaster articulation of turning shoulders and bending but linked hips & knees.
Bit of a colour clash here - and on his co-mould - between the yellow & the light blue.
Black stays the same
Purple becomes yellow
Yellow becomes white
Pale blue becomes red
The white & red colours together like this make me think Medic and on a car make him look like Masterforce Minerva
The Super Car Patrol were released first in Japan in 1990 as Transformers Zone toy C-333. They came back the following year, now packed with Microtrailer number 12 as set numbered C-375.
