The all-new 2012 Subaru Impreza made headlines earlier this year for a number of reasons – one of which was its expected highway fuel economy rating of 36 miles per gallon with the Lineartronic CVT (Continuously Variable Transmission). But fuel economy is not only a function of engine and transmission; here’s a look at Subaru technologies that contribute to improve fuel economy.
Whether or not a vehicle achieves good fuel economy is determined by its design, engineering, and manufacturing. It has to do with how vehicle components are made, what they’re made of, and how systems function.
While every aspect of a vehicle contributes in some way to its level of fuel economy, we’ll focus this discussion on how Subaru has improved fuel economy by addressing these areas:
- Vehicle aerodynamics – how a vehicle moves through the air
- Reduced weight – a lighter vehicle tends to achieve better fuel economy
– Drivetrain components and systems
- Component and system design – engineering for light weight, smooth operation, and aerodynamic efficiency
- Efficient functionality – operating with low losses of energy to friction
