    The peak hp and peak toque range remains the same at 5400 - 6400, 1370 - 4500 respectively.
    Assuming this uses the same hardware under the hood, what is the possible motivation to tune it for 5 hp less ?

    It is not tuned down, they just used a different way to measure/calculate power output.

    Still seems a bit odd.

    The 2018 figures were calculated metric HP which is a bit deceiving for US market so they now use the more appropriate calculated Imperial HP for 2019. Both numbers are derived from the measured 260 KW, which hasn't changed.

    How is it odd? It’s just a new method of calculating HP output.

    Something similar happened in 1971 - 1972 when US automakers switched from SAE gross HP to SAE net HP ratings. That, combined with early emissions controls made for a large drop in advertised HP in the early 1970s.
