For used car dealers, this is worth knowing: the internal combustion engine is far from dead, and it’s getting a serious upgrade. Engineers at major automotive suppliers including FEV Group, Mahle, and AVL are actively developing the next generation of combustion technology — using AI, advanced thermal management, and friction-reduction techniques to squeeze more efficiency and longevity out of gas-powered vehicles. That means the ICE inventory on your lot today may have more long-term consumer appeal than the headlines suggest.
The advances are significant. Geely recently achieved a 48.4% thermal efficiency rating with its latest hybrid engine — a record — using AI algorithms that adjust in real time to conditions like altitude, humidity, and temperature. Suppliers like Mahle are pursuing friction reduction through low-viscosity lubricants, optimized piston rings, and electrified engine auxiliaries, all of which improve fuel economy and extend engine life. Demand-controlled cooling and lubrication are also accelerating warm-up times and improving efficiency at partial load. For dealers, the bottom line is straightforward: consumer confidence in gas-powered and hybrid vehicles remains well-founded, and new technology is only strengthening the case for ICE vehicles as a smart, long-term purchase.
