VW Jetta - from 1.4L to 1.5L (with better MPG) Why?

My 2017 EA211 1.4L is imprssively fuel efficient.......

That being said, how does VOA get improved EPA numbers with a larger displacment?


I would point to a better drag co-efficient - but other factors may need to be considered.,

best to all,

Engines are getting more efficient with every passing year.
What you often find is that the slightly smaller engine is not optimum for the vehicle but the larger engine is.
I drove two Ford Cortinas, back in the day, and the 1.6L gave far better mpg than the 1.3L. Both engines were the same except displacement and both were from the same model year.

Gearing, shift points, fuel mapping, aerodynamics, tire choice are the first few things that come to mind. I'm sure there are many other potential factors.

I'd agree with above. And increasingly tighter emissions regs forcing car makers to eek every tenth of an MPG out thier car. Some of the new VW group cars put the car in neutral and turn off the engine entirely on long hill descents.

I've often found smaller underpowered cars can be less efficient as you have to work them so much harder, some of the hills here I've been flat to the floor and knock it down two, sometimes three gears just to get up. In my more powerful cars, I'm in 6th, barely touching the throttle at all, just a nice lump of torque as the turbo spools and pulls you up.

It's definitely innovations from these years. Manufacturers got to compete with more efficient new models.

I'm not ready for the "toaster" path of advancement (driving). In Naval Air - during the "Greatest Gen" days -- - - propellor aircraft to jet aircraft transition - the expression "Take it slow and easy if you want to get along with me" became the sane approach to the appropriate learning curve.........jets ate a lot of fuel, jets did not accelerate like prop aircraft............

You had to plan ahead - especially with a carrier landing...........

That's where I am - - - - planning ahead.

My 1.4L Jette is REALLY fuel efficient. And reliable. And fun to drive.

I know fossil fuel ain't forever. I know we have choices,.

Please forgive the rant.

Well, if Edmunds is to be believed, moving to a new Jetta would bump mpg city/hwy 1 and 2mpg respectively with 1 mpg increase in combined mpg. And a smaller fuel tank means slightly more often visiting the pumps.

Or get TDI unit, and increase your economy by another 25% or more. Kinda miss the 90 MPG days now our fuel is near enough $12 a gallon...

Diesel isn't an option in the US anymore.

I was thinking second hand, not new.
