Having been powered by a 0200, and now having a 912s, there is no comparison.
“O-200 runs quite happily on auto gas,”
So does the Rotax, it was designed to, but the Rotax uses a lot less, it is also a lot lighter, has a smaller frontal area and in the UK home built area it is more reliable. The support for the Rotax engine in the UK is also very very good. A 50 hour typically costs £25 all in, plugs at £2 each etc etc.
We will probably never see the 162 in Europe; it would be so inferior to the Euro wide VLA class that it would fail to sell to all except the most diehard Cessna fans, unless it had a big cost advantage. We are already shifting from the old 152 to the new VLA range of trainers, which use a mix of construction methods.
