The EPA rates my Ford Fusion Hybrid at 36/41 MPG. In 38000 miles I have averaged 42.5 MPG combines City Highway. I am about 75% Highway as well (which the EPA rates at 36 mpg) It's how the car is driven that makes the difference. I drive for mileage as part of the fun of having Hybrid. If The EPA says 265, I will easily get 300 MPG.

If the EPA says 265 I'll get 200 as I've been hypermiling in my last two cars and I need to unleash for a while. =)

Tesla did the right thing by doing a 5 cycle test on their own rather than letting EPA apply the 70% adjustment factor.

It's still the third-best Cd for a production car ever! The current Prius and the original Insight are right behind at 0.25.
I demand a rematch.
NO friggin way! That bumper alone would kill the airflow. This beating the S is laughable. Who can we call?

Ha ha! It must be the rear. See the citation:

TSLA will win
The 265 / 300 difference EPA 5-cycle vs. claimed range, is a bit better than the 35 / 40 difference for the Volt, and much better than the 73 / 100 difference for the Leaf. Meaning, Tesla was closer in their advertised range than both GM and Nissan.
I was under the impression that that wasn't possible anyway. I thought you had the option to do .7 instead of redoing old tests, but that all NEW tests HAD to be under the 5-cycle

From that CNET Article:
Lower than expected? I'm 100% sure Tesla knew that the 5-cycle range would be less than 300 mi. Nowhere did Tesla ever say the 300 mi range was using the 5-cycle test.
Almost everyone on this forum expected it. What does "lower-than-expected" mean? Lower than the author expected? Ugh. The media is such a joke--there are so very few good writers out there.

It's not (just) the writing. It's that there are even fewer who know how to do research, and even fewer still that don't have (political) axes to grind.
It is easy to do research in 3 easy steps:
- Edit Wikipedia (anonymously through a proxy) to say what you want it to.
- Write article with Wikipedia as a source.
- After publication quickly put your writing as source on Wikipedia.

I am not ready to hang my hat on the Cd of 0.24 being the absolute number for the Model S. The quote from the blog was "Cd of approximately 0.24". That leaves some wiggle room to be as low as 0.22 IMO. One reason Tesla would choose to publish the higher (in this case worst) spec would be the different configurations available for the Model S does slightly change the Cd number. Tesla choose to publish the highest Cd rather than publish each possible combination. Examples of different combinations: air suspension vs coil springs, 19" vs 21" wheels vs aero wheels, spoiler vs non spoiler, pano roof vs non pano roof. Someone with more math skills can figure how many combinations with just the variables I listed would be. I think it's a bunch. Tesla was just trying to keep it simple and is publishing the worst case spec.

Unlikely. In marketing, you always publish the best case numbers.
Edit: actually, I take this back, since I don't think Elon mentioned this with the intent to be used as an official number. So there could be wiggle room.

The Tatra T600 looks more aerodynamic. So interesting it's rated cd is less than the boxy front the 77 sports.
I still demand a recount. Besides the Tatra's flat nose with it's bumper, grill, headlights and look at the vertical windshield slope and exposed wipers, and door handles. I bet the bottom is not flat like the Model S. It's tall taller too.
So it has a pointy back end read wheel covers and no side mirrors. I still vote Tesla.
ETA:
Ah HA!
The website says "...Tatra only measured only 1:5 and 1:10 models [in the wind tunnel]..."
