[Accord Man]

The biggest difference between I6's and their V6 counterparts is torque - I6's usually have considerably more torque available at lower rpm than their V6 counterparts, and they usually rev a bit lower, tho there are plenty of 7k rpm i6's out there...


Also, V's have more vibration than inline engines. Simply because of the ossolition involed. But more power can be transmitted and a lower CG can be achived. Also the take up less space.

Most common production car I6's are underpowered for what they are. The I6 layout is one of the best balanced configurations you can have, it's easier to dampen the forces acting on the block...maybe not coincidentally, some of the most robust blocks around are inline 6's (Chrysler 4.0, RB26DETT, 2JZGTE...)

If you're looking into getting an inline, you can turn them into pretty good performers. There's a website called cliffordperformance.com that specializes in straight sixes.
