Actually, the HX is the successor to the VX, with vtec-e and EGR but with the 1.6L engine and significantly shorter gearing (especially final drive, about 3.75, instead of 3.25). Even the wheels are the same design, though an inch larger.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
