Yeah, we saw it too - Rotax has released a new fuel-injected version of their 912 engine.
We?d been aware of this project for some time, and the concept is exciting; but there are several reasons that, in its present form, the engine is not suitable for the RV-12.
Weight: The Rotax press release says the f.i. version weighs 6 kilograms more than the carbureted version. For the metrically-challenged, that?s 13.2 lbs - a significant increase and difficult to absorb, given the RV-12?s forward-cabin configuration and legally limited gross weight.
Size: The photos accompanying the Rotax press release make it quite clear that the engine will not fit in the RV-12 cowl. Re-designing the cowl and making new molds would be an expensive and time-consuming project, increasing the cost of the kits.
Cost: We haven?t seen final numbers, but the new engine is likely to be priced significantly more than the one we use.
We will consider the pros and cons of the new engine, but for now and the realistic future, we have no plans to offer it, either as a replacement for the existing engine or as an option.

Go for it!
If you can afford it and have the time and want to do your 12 EAB, then go for it. No doubt that someone will and no doubt, it will be successful. Are you that one?

I talked to the rep at AOPA and asked this question. He said too much of it is based around the existing design and didn't expect that to change anytime soon.

VANs not convincing!
I was never convinced by the main argument of VANs (I will pass on the even more ridiculous cowling issue): 13 more lbs of weight. Come on, this represents 2 Gallons of fuel or just 43 lbs of baggage instead of 50 or... make your pick out of this statement from VANs RV-12 brochure:
" two 210 lb people, 20 gallons of fuel and 50 lbs of baggage ? something rare in the Light Sport Category." (the healthiest pick being two 200 lb people... with lbs to spare!)
What about this more convincing reason:
"We are just out of a harrowing retrofit that we underestimated by almost a year and which created mayhem among our RV-12 builders so, we are not doing it again anytime soon"
The Rotax 912is will come when VANs gets over this, mark my word!

Updating'improving
Seems like a natural progression to facilitate installation of this engine for those who want it. It would require updating and re-certifying the kit and therefore, be expensive - I hope that Van's can afford to do this.
Guess it would depend on how many of the updated kits Van's would sell. Bottom line is economics and the future doesn't look good for me, at least. I'll be happy to someday have a flying RV-12!!!

For 4K you can put Airflow Performance Mechanical fuel injection on a 912.
The system has been flying for the last 3 years.
We posted this system about a year ago but had no takers due to cost. If you guys are interested in a installation on the RV-12, let me know.
