I don't think Honda's V-7 (4 cyls in front, 3 in back, 90° V) ever made it past prototype. I don't remember why. I would imagine that quelling the primary imbalance ate up more horsepower than having an extra cylinder created.  |
I guess they could make 3 on each side in the V and then one go in a vertical like an inline would, could even have a short 3rd camshaft to work the valves... now wouldn't that look odd???
