I thought by comparing itself to existing technologies, it was being up front that it’s just moving from purely theoretical to prototype. Maybe that’s not as clear to others?

I’m fairly certain every single point there was made about the Wankel when it was prototyped…look at it now! Edit: in fact, wankel side seals are the likely solution…it has the same rotary “side bleed” issue and they do ok.
Same for reciprocating piston engines and more.

Sure, it’s not ready for prime time, and no, it is no where near it’s theoretical potentials. What engine has been at this point? They got it to run, I’m pretty impressed with that as it’s much farther than most theoretical motor designs ever get.

No.

What kind of tolerances do you need to seal the chambers created by those rotors and then what happens to those tolerances from thermal expansion when the engine heats up?

Now ask yourself how you lubricate all of that and then notice the oil literally pouring out of the front seals of that engine.

All of those numbers are made up. Maybe someone did some creative theoretical napkin calculations but those numbers aren't based on anything that engine is doing.

For new cars, probably correct, but old combustion engines aren’t just going to dissolve away. I have two over 50 years old in my driveway. They can last a long time.
Also, India and China don’t seem very interested in skipping their turn at combustion engines (sad), so tack 50+- years on before the entire world even really wants to switch over.

I don’t deny average electric vehicles should soon outperform average normal gas engines (let’s ignore exotics as exotics). My point is switching technology across the board is a slow, painful, expensive process that won’t likely happen in 5, 10, or even 20 years IMO….and electric motors won’t ever totally replace combustion for all applications as some suggest.

The sound of that V 12….priceless!


But Ok….NSX cheap enough? <$158k


Yes, electric is here to stay, but for performance, so are combustion engines. Electric will surpass them someday, maybe soon. Not yet. They most likely won’t completely replace them. Too much riding on and invested in fossil fuel technology and infrastructure to walk away completely, IMO.

That was not that quick compared to equivalent combustion engines….>11 seconds? I expected much better acceleration, but not top speed. Turns out it has neither compared to some similarly powerful combustion engines.



Keep in mind, the Bugatti is made for top speeds, not acceleration, but wins on both counts.

The Chiron will accelerate from 0–97 km/h) in under 2.5 seconds, 0–200 km/h (120 mph) in under 6.5 seconds and 0–300 km/h (190 mph) in under 13.6 seconds. The Chiron's top speed is electronically limited to 420 km/h (260 mph) for safety reasons. The anticipated full top speed of the Bugatti Chiron is believed to be around 463 km/h (288 mph

Also, this is a Chiron, not the Chiron super sport version, not the top of the line. Weight is similar.

Electric is great…it’s not better at performance yet. Don’t oversell it.

Um….the horse and buggy still exists. It’s the main transport in many (often poorer) places, even some in America (Amish country).

You’re insane if you think the internal combustion engine is dead. Even if that was the worldwide goal, it would take decades upon decades to pull off and tens-hundreds of trillions in subsidies….and even then there are hundreds of applications where electric doesn’t work for hundreds of reasons.
If you believe that, why do you support expanding oil exploration and offshore drilling? Why destroy the few places left unadulterated for a horrendous energy source you claim is phasing out soon. That’s incredibly short sighted and dumb.

Besides, you might be unaware, the electric car was more accepted than combustion engines before, at the turn of the last century. We’ve seen this movement before. It didn’t turn out as you predict.

Electric is great, but it’s not a panecea, and it’s not a painless switch.
