I get 27.2mph at 71mph on the highway, when averaged with some back country roads and other driving. If you get much less, you may have a wiggly throttle foot.

I get about 20 MPG, I do mostly highway. I don't like the low MPG...but like most here, I didn't buy the Z as a fuel saver...

21 Mpg city/highway for a car like this and it's performance? No complaints here.

I do that sometimes as well.:tup:

Your first 5,000 miles you get shytty mileage. Then it improves greatly from 5-15k miles.

And summers are pretty bad for the VQ. Optimum gas mileage will be had between 50-82 degrees. Lower humidity days preferred as well.

Agreed as someone who has torn apart both 370z and Boxster the Porsche has engineered incredible efficiency into their cars. I will say earlier boxsters do have some terrible design features in motors and transmissions but newer cars seem to have overcome the issues.

My 986 2.7 liter and 2.5 liter Boxsters got about 21 mpg combined and about 26 to 27 highway. Clearly newer boxsters are more efficient but I suspect combined mileage is still in mid 20s.

For me it's tough to compare the $30k Z to $45k Boxster. They really are quite opposite of each other.

Boxster is refined drivers car while Z is a basement bargin sport GT car. The Z packs ton of value But it will never be a match to much lighter balanced Boxster as a refined road car. Now when it comes to performance the Z definitely packs a punch. I'm a long time Porsche club member. Since the 70s. The 370z is truly equivalent of 240z was back in the 70s. Not as well designed as 911 but packing huge value.

As a driver I got bored with boxsters perfect handling. I know that sounds strange but the car on the street was so nueteral and balanced that for me it was boring. The 370z feels very retro to me. I love looking out over that long hood with a car that actually will toss the tail out with very little effort. Yeah Z is not most efficient car but it's built like a tank? This means we can go to the track and beat 370z and not worry about reinforcing every area of the car. Yes it has little foibles such as hot running VQ , ice mode abs issues, and fuel starve but in general the car is bullet proof.

I just watched a show on the history of the Cobra. There was a scene where the car came into the pits for a tire change. Before the new tire was installed, a pit crew member came over with a bucket of water and just poured it all over the brakes/wheel to cool it off.:driving: Yep, we've come a long way in technology.:tup:

REP REP REP REP.:iagree::tiphat:

I its the most perfect analysis of the Z thus far. Eloquently said and it captures the true driver's essence of the 370z. I actually feel the same way on porsche handling. Wayyy to neutral. Leaving some margin of era keeps it fun. The Z is pretty neutral with VDC on. Take it off and its a bucking bronco that somehow still manages, by some miracle, a high level of precision with a trained driver behind the wheel.

I test drove the 911 991 S and wanted to see how an eco run on the freeway would do me. I got about 30 mpg without going downhill. Its rated at 27mpg freeway.

I'm getting about 23.9 mpg

Pretty good IMO


- The One -

one trip recently from fullerton, ca to san diego, ca netted me 34 mpg, but that was doing a very boring 55mph in the slow lane all the way there lol.

Excellent post. Saw an issue of Top Gear where Jeremy Clarkson evaluated an M3 vs Boxster and he chose the M3 over the Boxster because of the exact reasons you mentioned. Porsche made the Boxster too good (wow, that sounded weird).

Maybe that's the same reason why some people aren't fans of the GTR?

Did anyone notice that he says the Boxster pretty much spanks the Z in everything but on the Porsche website it shows a 0-60 time of 5.5. I think the Z is faster no?

Yup, sure did. But what I think OP meant by spanked was Boxster gets better gas mileage doing that slower 0 to 60! :rofl2:

Picked up my new Z today and got 25.6 MPG driving it Yuma to San Diego..
