In my experiences, wankel engines really kick ass. The mazda 1.3lt engines put out a hell of a lot of horsepower for such a small engine. However, the brighter the candle burns, the faster it burns out.. Mazda's rotories DO eat apex seals, and oil (the oil bit is by design). You really have to give them a lot of TLC to keep them running, but boy can they run. One major weakness of mazda's rotory engines is low torque, but I think that's largely due to the lack of displacement.
Not intrisctic to wankel engines specificaly, but the mazda rx7's also had 50/50 weight distribution, combined with a strong engine and rear wheel drive makes it a really strong contender.
