Re: Ford to improve 1.0L EcoBoost's fuel efficiency! Quote:

Ford sets the wrong expectation by repeatedly highlighting the 1.0L displacement of this engine. When you have a turbo 1.0L engine giving the approximate performance output of a 1.6L NA engine, we should expect the fuel consumption to be in the range of a 1.6L engine. After all, turbo helps jam in a higher volume of air in a smaller space, but the engine runs on roughly a similar fuel-air ratio. This is not an engine that's 25% larger than an Alto engine, with 25% worse mileage than an Alto.
The key observation I see about the EcoBoost engine is the obvious one - it is immensely more sensitive to driving style than a higher capacity NA engine. While the EcoBoost can lose 40% of its mileage with spirited driving, a higher capacity engine (say the 2.0L in the Cedia) would not exhibit such a pronounced variance due to different driving styles.
This is why with reasonable driving in the city I get: Quote:

And on the highway I get anywhere from 14.5 to 18.6 km/L based on how nutty I am with my right foot: Quote:

This time around, I got an overall trip mileage of 18.6 km/L for a distance of 415 km. More interestingly, I checked the MID ... just before ascending the ghats..., I'd had a mileage of 19.9 km/L. |
That said, some of the improvements sound interesting: Quote:
they also developed a new dual mass flywheel. This enabled cylinder deactivation to take place at a wider range of engine loads and speeds, and helped minimize noise, vibration and harshness levels.

I wonder how that flywheel will alter general driveability, without cylinder deactivation.
And on that topic of cylinder deactivation: Quote:
Even for an aggressively downsized engine such as the 1.0-litre EcoBoost, a significant improvement in vehicle fuel economy could be found by exploiting cylinder deactivation

I've heard of cylinder deactivation in V6 and higher engines, this is probably a first where you're starting with a measly 3 cylinders, and are already looking at turning one of them off!
