There are rpm limits in breaking in the engine for very good reasons because there is much more to breaking in an engine than "seating the oil rings". There are lots of other engine parts that need to work a while so that rough edges and machining tolerances can smooth out. Running high rpm in any new engine is an Rx for problems-bad ones.

However, hard acceleration for a few seconds at a time in the first 500 miles at low speed works for all engines. This pressure does complete the seating of rings and smoothing other engine parts + transmission. It does not overheat the engine-the reason for short bursts at a time at low speeds. Also, if there is a system that needs to be adjusted-the issue is less likely to damage something.

Oil and filter change at 500 miles is a good idea for any engine to remove metal particles and again at 1K miles. Don't use synthetic oil until 1K miles so that the non-synthetic oil can promote break in (not as slick).

Heat is what kills engines and transmissions. New engines run hotter until the parts are worn enough to smooth up.
