New points, as in a car engine (6)
I believe the answer is:
piston
'a car engine' is the definition.
'piston' can be an answer for 'engine' (thesaurus). I am not certain of the 'a car' bit.
'new points' is the wordplay.
'new' is an anagram indicator.
'points' anagrammed gives 'PISTON'.
'as in' acts as a link.
Can you help me to learn more?
(Other definitions for piston that I've seen before include "Mechanical plunger" , "Valve that's instrumental" , "Block sliding in hollow cylinder in machinery etc" , "Transmitter of motion from camshaft to valve" , "Sliding piece in a cylinder" .)
