Different power figures for the same model and year - why?

[UKGTC]

It’s not to mislead, it’s because PS and Nm are the metric units of measure used in Europe.

If it was to mislead, then why quote acceleration figure as 0-62 mph as that slower than it would be if quoting 0-60 mph?

Well I’m still using the 0-60 mph calculation because it makes my car go faster.
