"Warp Drive = capable of sustained, repeated use of Warp, Warp Engines = only usable for a short period of time before they burn out and/or very slow Warp. Whle the Phoenix was capable of generating a warp bubble, it may not be strong enough to consider it Warp Drive."
Happy Target, you could be on to something there. That might explain why in First Contact, after the Phoenix supposedly went warp and then throttled back, we still saw a fairly good sized Earth through the her windows. Perhaps Cochrane initiated a warp bubble and got going at a fairly good clip (impulse using some low level warp field) before turning around.
If the Phoenix had actually gone warp 1 or higher, she probably would have travelled much further. I'm sure the math majors out there could actually figure out how far she flew based on the Earth's (I think) angular size. Either way, she didn't leave the vicinity of Mother Earth by a long shot.

Well, Riker said in A matter of Time that Warp coils only allowed ships in the 22nd century to travel no further than a sector (or two?) And that Warp DRIVE allowed them to expand out into the universe...
Maybe this fits in with the comment in "The Cage" where they had broken the 'time barrier' or what ever.
