Two things:

Eric:  VTEC isn't variable intake length diameter or intake runner length, 
it's just variable valve lift and timing control.  BMW has "VANOS" which is 
VTEC plus variable length runners...

Aaron:  There are indeed cars that use electric steering boost.  Can't 
think of any off hand except the MGF, Rover's small mid-engined roadster in 
Germany.  Several GM cars use electronic boost I think-- I'm thinking 
Saturn maybe?
