Do you consider maintainability on any of these top 10 winners? Most of the engines appear almost impossible to service.

I'm not sure about the rest of the engines but the R58 BMW have looked ahead.
Cylinder bored special coating to reduce wear massively.
Engines kept warm to prevent cold starts the next day or even the 2nd day since start.
Less Components.
Common Components over several engines.
Internal parts easier removed for service.
Stronger block and insulated. Petrol and diesel the same to cheapen.
25000 kms or 24 months between service is great.
Pollution is causing complexity but think simplicity still on manufacturers mind most likely to be completely motivated by cost largely.

Servicing certainly is a challenge, ras1500, and unfortunately we don't have a good way to track long-term durability. If there are servicing problems with any engines we put on our list, we surely hear it from our readers.

Hello: If I have ever finish my proof of concept engine, How would I enter it in the 2017 competition. Oh ya, No fuel, No solar, No batteries( other than a 12vdc system batt), no burning our precious oxygen and no carbon foot print...(outside of manufacturing) I will keep working, by the grace of God, to have my Aveo retrofit done by year end. Anyway Thx

We're certainly intrigued, Gravcore. But the engine has to be available in a production vehicle. Keep us posted.

I take issue with this list in that the hybrids also have electric MOTORS, which by definition are not engines. Unless this list is considering only the ICE portion of the listed hybrids?

We have looked at other names for the awards such as Wards 10 Best Propulsion Systems, soakee, but it doesn't work well for an award. We look at it like this: Everybody likes the Grammy awards and knows they represent musical excellence even though gramophones are no longer used.
