What Does "XR4Ti" Stand For?

It is often safe to assume that ‘X’ is representative of ‘experimental’ in the land of European Ford and 1960s Lincoln-Mercury products. This particular string of letters does indeed start with ‘experimental,’ though it was only truly experimental for the North American market. From 1985 to 1989, Ford imported the three-door Sierra XR4i model and labeled it a Merkur XR4Ti.

XR4Ti stood for Experimental (X), Racing (R), four cylinders (4), Turbocharged (T), and fuel injection (i).
