I know my Fiat Spider doesn't( I think the VW's did though ).
Depends on the exact model and year. Many do; some do not.
Still, most any auto is just full of analog
computing elements.
The carburetor is full of them. EFI (Bosch Electronic Fuel Injection)
was available on "Type IVs" (Squarebacks and Fastbacks) in the late
1960s, then later on MicroBuses (like my 1975 and 1976 ones). It's
clearly an analog computer with a network of sensors, comparators
and actuators. There's even instructions floating around on how to
do component-level diagnosis.
I did see and knew there were EFI bugs as well from that era. Very
good & reliable, what is troublesome is those guys doesn't heed the
manuals and keep hoses in good repair.
Gee, I rather go with injection (dependable designs is a given) of
any types over the carbs (had second hand experience w/ my parents
dealing with an toyota 90 tercel w/ dying carb very recently. Seems
very rare few knew how to do a carb right especially those crankerous
toyota carb or like.
