In the eyes of today’s collective automotive consciousness, there’s only one way to quickly raise the average fuel efficiency of a fleet of vehicles by the time the new government fuel-economy standards come around: shove a hybrid drivetrain into existing platforms. Nearly every manufacturer has jumped into the hybrid game, either to produce additional horsepower and torque in their high-performance models in place of large-displacement engines, or to boost fuel economy by a few miles per gallon. Consumers have come to think that anything with a hybrid badge is bound to be cleaner and more efficient than its nonelectrified counterpart, even though that’s not always the case. Mazda is one manufacturer that has struck off in a different direction. The company has just announced that its new generation of Sky engines will increase the company’s average fuel economy by a staggering 30 percent -- all without the added weight, cost or complexity of a hybrid battery and electric motor.
The company says that its new gasoline engine will be able to provide 40 mpg when bolted to a new 6-speed automatic transmission, while a diesel variant will see more than 43 mpg. Mazda has been notoriously anti-hybrid in its approach to increasing fuel economy, but it’s not alone in exploring ways to increase the efficiency of standard gasoline engines.
Fiat is another manufacturer that has turned its attention to technologies such as direct injection and turbocharging to increase fuel economy. The company’s line of Twin Air engines relies on small-displacement architecture and forced induction to turn out hybrid-besting fuel economy. Likewise, both Ford and Chevrolet have dipped their toes into similar theories with engines found in the Fiesta and Cruze, respectively.
Remember, just because it says it’s a hybrid, that doesn’t mean it’s your best option for saving money at the pump.
