City MPG Casual Driving
- Thread starter 7eregrine
- Start date
For those that run into red lights every 30-60 seconds, I wonder if something can be done similar to the mild-hybrid or Honda's idling-stop (http://world.honda.com/motorcycle-picturebook/idling-stop/). Would the new HCCI engine be able to do something to save fuel while idling at stop light (and without affecting the ability to depart quickly)?
i-stop and i-eloop. Not sold on the US models though, probably pushes cost past their target market.

My brother's new Volvo XC90 T5 shuts down when the car comes to a stop. Its obnoxious because of the way it "slams/jars" when the engine starts back up. Plus its a royal pain when you're trying to run full blown AC in a hot humid Southern Summer.
Luckily it can be turned off upon start-up. Certainly not worth the miniscule gas savings its supposed to provide.
I have yet to ride in another vehicle that has this feature, but its one I would find of little importance and would avoid at just about all costs.

Yeah like craigo said Mazda does have i-stop and i-ELOOP designed specifically for this stop-and-go traffic to save fuel. In fact, Mazda's i-stop is superior than most other similar systems as the engine stops at a pre-designed position so that it can restart with only injecting fuel without much help from the starter. It's the smoothest system available on the market right now. Unfortunately we can't have a taste of i-stop and very few models offer i-ELOOP in the US.
Thanks craigo and yrwei52 for pointing out i-stop. From Mazda site (http://www.mazda.com/en/innovation/technology/env/i-stop/):
- the system improves fuel economy by approximately eight percent
- the restart takes place in a mere 0.35 seconds (internal measurement on vehicle with automatic transmission), which is about half of the time taken by conventional starter-motor idling stop systems.

Based on your history, your "current MPG" is 22.9 and your previous trip is even worse ⋯ (uhm)

They were ever thankful I knew how to disable it. It was one of their biggest gripes.

Not hard to do. It's really miserly at those speeds. I usually get 35mpg or so if I set CC at 35-40

That's typical. 22.5-23.5 is what a AWD 2.5L CX5 gets daily driving with mostly highway in my own experience. That said, I still get 30+ doing 35mph in residential areas.
