C4.5?
Seems like when I talk to people about C4's we are always saying, "earlier ones vs later ones" or "the squarer ones vs the rounder ones" or "L98 vs LT1/LT4", etc.
Seems like it would be easier to refer to them as C4's and C4.5's.
I think it is a good idea so I'm going to start calling them that and eventually it will catch on!








1984 = C4
1985 = C4.1 - L98 engine introduced.
1986 = C4.2 - First convertible since 1975, third brake light, antilock brakes, electronic climate control, and key-code anti-theft system.
1989 = C4.3 - ZF 6-speed manual replaces Doug Nash 4+3.
1990 = C4.4 - ZR-1 is introduced with DOHC LT5 engine. Interior redesigned to incorporate drivers-side air bag.
1991 = C4.5 - Restyled exterior
1992 = C4.6 - LT1 engine replaces the L98 - traction control standard
1994 = C4.7 - New interior including passenger airbag. LT1 receives mass air flow sequential fuel injection.
1995 = C4.8 - Minor exterior restyling
1996 = C4.9 - Optional LT4 engine with 330 hp (246 kW). Collectors Edition and Grand Sport special editions. First year with OBD II diagnostics.
So C4.5 would be 1991 and newer.

C4's really brought a lot of technology and changes throughout the years. Don't know why they don't receive more respect among the generations.

Yeah, I'm sticking to early and late as my description. The middle years get cloudy (late 80's early 90's) but "early" and "late" still work if you're talking about a particular feature, i.e. body, wheels, engine, interior, etc.
The entire car except the motor and trans early vs late.
Motor and trans related l98 vs lt1.
Its a nightmare when trying to search for a symptom or info on interior stuff here since you never know what a threads going to have in it till you go inside the thread and see what year it is.
