But there are also 3 reasons why a turbo of similar performance numbers, and used in a similar way will in fact yield better fuel economy:
1. it weighs less
2. it has less friction (smaller, fewer cylinders, etc)
3. It operates at less vacuum ( which is parasitic) more of the time
That's it.
documented by an MIT study and another from one of the national labs on the west coast.
The magic combination seems to be turbocharging + direct injection so as to keep the static compression ratio hgih.
yea, sure you can just mash the loud pedal, but you could do that n the old, larger, NA motor too.

As far as the weight. Fact is the 718 weighs more than the 981, not less. Maybe just a more sophisticated / heavier turbo?
As noted in my earlier post, the 718 S is rated at 26 mpg highway. My 981 regularly get 28 mpg or better on the highway. Where is the advantage?
It will be interesting to see what happens in real world tests.

Fuel Consumption
Manual PDK
City (estimate) 20 mpg 21 mpg
Highway (estimate) 26 mpg 28 mpg
Which is a bit less (28mpg?) than on the 981S.
Interesting....dropping the displacement by nearly a liter you'd expect a drop in consumption in a steady state highway mode but not on this model.
BTW, comparing the prices on the 718S--equipped the same way we have it on our 981S--the price goes from a MSRP of $66K to $75K in 4 model years.
Looking at the standard equipment and options, is it still correct that there is no bluetooth connectivity in the basic radio setup to stream music (Spotify/Pandora)? With the price on this model in the $70K without many options I'd hope that would be included given cars in the $20-25k range have it standard.
Around town my 981 S gets 16-17 or so, but long distance steady highway it's more like 32-34. Laz - 7 years ago |
