I completely agree, but Mazda has a history of solo flying with things too long before others begin to lose interest. I have to admit that no-one was particularly interested in the rotary engine mostly because of its horrendous reputation in the early 70's but with an appropriate cash flush partner its explosive idiosyncrasies could have been ironed out; Ford would have been perfect at the time. The Miller Cycle was a legitimate entry into the interesting engine ledger despite not being particularly innovative, it was basically a slightly new approach to an old idea, but what a new approach! Had it been developed fully it would have been a power rich, reasonably fuel efficient, quiet and smooth powerplant with above average reliability and would have slotted beautifully into a more luxurious range, but Mazda kept it all to itself. Guess we'll have to wait and see whether they decide to share this time around or not, but unless they do then they'll always be the also-rans.
