I found some guys who posted their impressions on their rx-8s in Japan.

I picked up the fuel efficiency from those reports.
I think those who posted their impressions are under their running in. So, the below numbers would not be so correct as of now.

case1)
9.4 km/l , total 400km , 1500-3500rpm , expressway + city, 250ps 6MT

case2)
9.3 km/l , total 1000km , 5000rpm , expressway + city
(8 km/l , city area)
(13 km/l , at 110km speed , expressway)

case3)
9.2 km/l , total 479km

case4)
7.6 km/l, total 300km, ? , 250ps 6MT

case5)
10.5 km/l, total 500km, 3500rpm, 250ps 6MT, expressway

case6)
6.3 km/l, 250ps 6MT, city (including traffic jam)

Edit: add case4
Edit: add case5/case6

 

Some conversions for you guys:

9.4 km/l = 22.1 mpg, total 400km , 1500-3500rpm , expressway + city area


9.3 km/l = 21.9 mpg, total 1000km , 5000rpm , expressway + city area
(8 km/l = 18.8 mpg, city area)
(13 km/l = 30.6 mpg, at 110km speed , expressway)


9.2 km/l = 21.6 mpg, total 479km

 

It's $5 (US) per US Gallon here in the UK folks (£0.80p/litre). Aren't you happy you don't live here!

 

Which gearbox gives these MPG?

 

how did u find them?

 

US$2/gallon. No wonder the europeans drive smaller cars. I wish gas was $5/gallon here so that people would stop buying SUV's.

 

Alessandro-san, I added gearbox type to the list for the first one.

There are a lot of BBS in Japan, I found these reports in 2 or 3 of them. But, the most big bbs for the rx-8 is here.

 

Yep, we have narrower roads, permanent gridlock, nowhere to park in our overcrowded cities and expensive fuel. Marvellous!

 

yea serious. soccer moms in SUV's are the WORST.

 

*cheer*

 

...and to think, the S6 13B would get 18mpg if you were really nice to it

all i can say is i'm totally blown away: bravo Mazda!! :D
