multi-cylinder, synchronous-firing engine

Do you really like single-cylinder motorcycles? Wish you could live that thumper life, but in a car? Imagine an inline-6 engine, but instead of that buttery smooth 1-5-3-6-2-4, you get one really big bang every 720° of crank rotation. That way you get to avoid all the issues associated with comically large pistons and bores, and still get that sweet sweet garbage NVH that you know and love.
