    I don't have time to format this properly as an article at the moment, but have you guys seen this?

    Apparently Nissan has developed a variable compression ratio engine that works a little like variable valve lift, except it varies piston travel. They're claiming that it varies physical compression ratio between 8:1 and 14:1 to better control combustion in high-power and high-efficiency situations alike. I guess this will be replacing the current Mercedes-Benz sourced 2.0L in the Q50 and Q/QX30? It'll be interesting to see what it delivers in the real world.

    Wow, that is a bit wacky. It looks like it affects the cylinder / crankshaft centerline relationship? Honda has offset the cylinders away from typical TDC, to improve the efficiency.

    Someone kindly made a video clip showing what the linkage looks like in motion:

    Surely that will be reliable for years and decades to come. :rolleyes:

    Maybe even the whole warranty period.
