The first commercially successful internal combustion engine was developed by Jean Joseph Étienne Lenoir in 1860. This engine, which he installed in his "Hippomobile," had about 1.5 horsepower. Lenoir's engine was a significant early step in the evolution of internal combustion engines, though it was relatively inefficient by today's standards.

The first non-commercial internal combustion engine is often attributed to François Isaac de Rivaz, who designed and built one in 1807. This engine ran on a mixture of hydrogen and air, ignited by an electric spark. It was not meant for commercial use but was rather a prototype to demonstrate the concept.

We have come a long way since the creation of the first combustion engine. This small 4-cylinder engine produces over 300 horsepower, and with tuning, you can get close to 400 WHP. Upgrading to a turbo can boost it to over 500 wheel horsepower when using 104 octane or E85 fuel. I believe this engine deserves recognition, especially since everyone often talks about the legendary 2JZ and others.

I believe that our passion and eagerness drive humans to push themselves to levels that most of us cannot even imagine. Although I don't have data on this phenomenon, it is undeniably impressive. We sometimes do not give ourselves enough credit.

Disclaimer: This is purely my opinion on EVs. You do not have to like it or accept it. It does not mean EVs are trash; this is how I see it.

Unfortunately, I cannot say the same thing about EVs. In terms of Engine and or EV drive trains, there is little to do to innovate. For example, car companies decided to change from port injection to direct injection, which is a challenge they achieved, and each irritation of GDI improves and becomes better.

Each time we humans achieve a milestone (combustion engine, airplane, cars) and figure something out, we advance as a species. In most cases, our kids become smarter than us because our experience in life and genes from previous generations carry information that is passed on to our offspring. Staying on top of technology and keeping up with challenges are good things. EV electric motor can be more innovative in adding a turbo to decrease engine displacement. Dealing with emissions and all that, those are all challenges that make us smarter. Maybe with EVs, they make better electric motors, but they are limited to what the planet can offer. We do not live on wonkonda.

Electric vehicles (EVs) are packed with technology. Innovations such as self-driving features are impressive, but ensuring compliance with EPA regulations is an even greater challenge.

I'm curious to see what will happen in the next 20 years regarding the supply of lithium and cobalt. Let’s observe how much of these precious metals the Earth can produce.

When looking for engines with similar horsepower, especially in the range of 240 to 320 horsepower, these manufacturers often use their 2.0L or slightly larger turbocharged engines for a balance of performance and efficiency. Remember, actual horsepower might vary slightly due to tuning for different markets, emission standards, or model-specific applications. Always check the exact specifications for the model year and trim you're interested in for precise comparisons.
