The writing may be on the wall for combustion engines—but it’s not etched in stone just yet.
In an era where electric vehicles (EVs) dominate auto expos, press cycles, and corporate forecasts, it’s easy to believe internal combustion engines (ICEs) are relics of a dirtier past. However, while governments and automakers charge ahead with electrification, a countercurrent of innovation and resistance is ensuring the gasoline engine won’t go gently into the night.
A Rapid Acceleration Toward EVs
Global EV sales are projected to surpass 17 million units by the end of 2025, according to the International Energy Agency. Regulatory mandates from the EU, China, and several U.S. states are further pressuring automakers to shift lineups toward zero-emission vehicles.
Even legacy manufacturers like Ford, GM, Mercedes-Benz, and Hyundai are investing tens of billions in EV infrastructure, battery technology, and manufacturing plants. It certainly appears as though the clock is ticking for combustion engines.
But Not So Fast…
Industry heavyweights like Toyota’s Chairman Akio Toyoda argue the future is multi-pathway, not mono-powered. In a statement, he noted:
“The enemy is carbon, not the internal combustion engine.”
That nuance matters. Because while full EVs are vital for reducing emissions, they’re not the only solution—especially in markets where electricity is still produced using fossil fuels.
The Case for Synthetic Fuels and Hybrids
Innovations in e-fuels and hydrogen combustion present alternative lifelines for traditional engines. Porsche, for example, is backing synthetic fuel development that allows existing engines to operate with net-zero emissions.
Hybrid vehicles also continue to be a compelling compromise. Toyota’s wildly successful Prius and newer plug-in hybrids offer lower emissions without full reliance on electric grids or battery minerals.
Infrastructure & Accessibility Still Matter
It’s also worth noting that EV infrastructure remains uneven globally. Charging deserts exist even in parts of North America. Meanwhile, cost and reliability barriers persist in emerging markets, where gasoline engines—while polluting—are often the most practical option.
Emotion Still Drives Combustion
Beyond engineering and emissions, there’s another reason the combustion engine may never fully die: emotion.
For purists, enthusiasts, and even cultural icons, the visceral experience of engine revs and gear shifts is irreplaceable. Automakers like Toyota’s GR division or Dodge’s last-gen Charger Hellcat have built cult followings around the analog, mechanical thrill of gas-powered driving. Read More
So, Will EVs Kill the Combustion Engine?
In practical terms, combustion engines will decline—but not disappear. Expect to see:
- A sharp rise in EV adoption, especially in cities
- Combustion engines phased out for mass-market vehicles
- Hybrids and synthetic fuel-powered models for enthusiasts and niche users
- Regulations pushing innovation, not necessarily bans
Final Thoughts
The future of the internal combustion engine isn’t binary. It’s not about EVs winning and engines losing—it’s about evolving priorities. As EVs claim the spotlight for environmental and economic reasons, combustion engines will retreat into the shadows—but perhaps never vanish entirely.
