OK, let's play Dr. AEHaas for a moment. Which of the three engines featured in the article has an oil-water heat exchanger?

I suspect (without a shred of proof) it never went into production due to marketing - some reviews of the engine gave it high marks for its performance. It'd be hard to sell a luxury car with a 1.6L engine when competitors have 3L and up V6/V8's etc. Then again, perhaps there were long-term reliability issues.

A few years ago a read an article about some testing Saab was doing with variable compression ratio. The head actually tilted to vary ratio to suit load and could go as high as 14:1 under light throttle and dropped some under acceleration do it could get by on pump gas. Haven't heard anything on since, obviously because of the intake manifold this design was aimed at inline engines, imagine a V8 that could do that talk about an engineering nightmare.
