If I live long enough I guess I will need to convert my 3.5 Coupe to an EV

My best guess at this point is that EVs will become common in large urban areas while advances in thermal efficiency of IC engines will lead to them continuing to be used for long travel. ICE tech is really moving forward. Just the OM654 and OM656 are pretty wild. Add the unknowns from things like the Achates engine, Koenigsegg's camless engine tech, even the new tinkering with rotary engines and ICE's may soon be almost as clean and thermally efficient as EVs.

I might get into them myself one of these days. One of my clients owns a basic Tesla - he was telling me an approx MPG comparison is 140. Also, amazing how much less is going on than in an IC engine, less in compexity. The OM656 with 2 turbos and a supercharger reportedly will push the 4700 lb S400D from 0 to 60 in less than 5.4 seconds and get a combined 45 mpg.
One imagines it could be tuned down a bit, put in perhaps a 3600 lb car (weight of a '90s BMW 535i) and get 50 or more while still tearing it up pretty well. But the complexity of that engine is a tad scary. The full treatment model has two turbos, a super, and VVT. The number of moving parts is much higher than in an EV. But who knows, there are likely downsides to EVs I'm not aware of.

I think the Lithium mining industry is going to be a major issue as the need increases.

My brother got Tboned in his Tesla a few months ago and I’m positive he wished he was in a s class

Similarly, another leading contender in the 'save the ICE' sweepstakes, Koenigsegg's camless Freevalve motor has possible issues. I really know next to nothing about it. It's hard to get solid info. I read they have a 3 cylinder 2.0 liter camless engine producing 600 hp and will release it in a new model soon. They sort of won the holy grail prize with the programmable valves thing. The downside so far, it's expensive. New, lightly produced stuff always is, of course, would improve with greater production numbers. That they've done this well so far is pretty wild. The other problem is that various seals are prone to high rates of use and degradation. Speaking of costly maintenance.
OTOH, if the OM656 could be built with a camless head, some of the perhaps more worrisome complexity would be jettisoned. The VTT systems are brilliant innovations but introduce more complexity of course. I've read that the Beemer heads who rod the M50 motor prefer it in it's first two years iteration. They refer to it as the M50 nv (non VANOS). Less fragile they say. MB's VTT operates similarly, I don't understand the differences. The one I like best so far is the Achates opposed piston engine. Fewer moving parts, they are apparently making 2 stroke work and be clean at the same time. The prototype for the army is part of the same motor project for 18 wheelers with Cummins. Meets the 2027 Cal emissions requirements. https://www.youtube.com/watch?v=UF5j1DvC954

Wouldn't that be cool in the engine bay of a 911. It'd also be the schnizzel for busses with rear engines. Conventional thought was that NOx emissions would kill the diesel. But, DEF fixed that. What effectively killed the passenger car diesels were particulate emissions (micro-soot). Last edited by Autoputzer; 04-04-2021 at 06:54 PM. |

The prototype is not boxster shaped. Not sure why, I read somewhere them talking about needing to use off the shelf parts to construct it, that later it would have the benefit of serious retooling that factory support provides. God only knows what's going on at this time.
The only seriously engineered engine so far that I know of with that tech is the Cummins engine. Not traditional looking, oh well, reportedly performs pretty well. https://www.youtube.com/watch?v=Mfy05zqn324 That vid might move on to this one, an interview with the founder of Achates. Interesting fellow. https://www.youtube.com/watch?v=zf6OH4iVUkY
