Good question. The US 2012 Stihl catalog lists the 362 (type I) as 4.6 HP and 13.0 lb. In the US 2014 catalog they list the 362C-M (type I) as 4.7 HP and 12.8 lb. (it was actually 4.69 HP rounded up as listed in the 2016 catalog). The 362C-M type II is 4.8 HP according to the Stihl Germany web site.
Hp(m) vs. hp(i) plays a role with what the kW translates into - both are bhp really, and hp vs bhp have had no real meaning after the ol' SAE gross hp (that was calculated, not measured) went out of use.
Some times it varies between different markets if the brand use hp(m) or hp(i) - there is about a 2% difference, that translates into .1 hp at about 5hp. As an example, the 3.5 kW of the 562xp is translated into 4.8 hp(m) in Europe, and 4.7 hp(i) in the US. Stihl does pretty much the same with the 362 - but what both brands do in other saw sizes vary.
Stihl and Dolmar have a history of presenting hp(m) as bhp in the US, which might lead readers to think of hp(i) - while it really was hp(m). It isn't a lie, but there are a lot of people that (wrongly) will assume that bhp is hp(i).
Then there is the question of how many decimals the kW numbers that the hp was calculated from had, some times it does matter.
Then (2), how the power band are om both sides of the max kW rpm will vary quite a bit, so
the max numbers just is an
approximate pointer to
about what to expect anyway.
A saw family that is known to fail miserably on both sides of max power rpm is the 029/MS290 family, which have created rumors that the specs aren't true. Independent tests show they
are true, the saws just have a terribly bad "power band" on both sides of max power rpm, so they perform bad for the rated power..
