MPI injects the fuel right above the intake valve for each cylinder. This
is more efficient than a throttle body. TB is only slightly better than a
carb in the fact that it does use an oxygen sensor. All cars now are MPI as
opposed to TB.

anybody know when volvo switched from throttle body to multipoint fuel
injection? i think its around the 2001 model year but would like to know
for sure.

is there any real difference in reliability, fuel economy or maintenance
headaches between the two?

given the choice, would you pay extra for multiport over throttle body
injection?
