Think the standard gas engine can't measure up to hybrid vehicle performance? A new gasoline engine breakthrough, along with recent innovations may invalidate that premise.


Quote from the article:

Admittedly, gasoline automobile engine at the turn of the millennium was disappointingly inefficient. While there had been great advances in digital control and performance tuning, the base efficiency of the engine proved only slightly improved from designs of two decades prior. Today that's starting to change. There's two basic schools of thought. One is to adopt a radical redesign, going for technologies like electric motor-driven hybrids or full-electric vehicles. The other approach, equally promising, is to keep the gas engine, but to reevaluate every engine part and their operation. Companies like Ford have enjoyed great success with this approach, employing engine technologies such as direct fuel injection and turbocharging to milk V8 performance out of a V6. Now a breakthrough in the oil rings that line the cylinder head in gas engines and keep it lubricated with engine oil may allow even more impressive performance on a gas-burning engine.
