Rotary engine vs piston engine

Here are some others to consider, I always thought the Wankel had problems with seals and point wear on the piston, as well as oil-burning and fuel consumption issues that did not seem so great in 1973, but grew as efficiency of regular piston engines developed.

If I remember correctly there's no engine braking either, so when you close the throttle it doesn't slow down! You need to get on the brakes pretty sharpish.

There'd be less engine braking, certainly. Engine braking is almost entirely down to compression ratio, and w ank els have quite a low CR. Not as low as 2-strokes though.

Speaking of 2 strokes, I just saw an old Saab 96 the other day, still rolling along like the last 40+ years never even happened.

I would love a 2-stroke Saab.

I think the biggest single factor in the failure of this engine was the name!

Rather like when Mitsubishi tried selling the Pajero in Mexico.
Upside was that my brother in Antigua got a rather nice car at a low price, when Mitsubishi cut their losses by off-loading in the nearest non-Spanish speaking market.

Mitsubishi call it a Montero here. They also build the Outlander Sport here.

My ****el is high on emissions

I'll bet you suffer from a lot of pinking though.
