View Full Version : Whats the fuel mileage going to be like? Spoonie 10-01-2002, 12:37 PM Any ideas? I've yet to see this question asked. If it has been asked before, my apologies.

A search using the search button on "mileage" finds lots of threads. For example this thread (http://www.rx8forum.com/showthread.php?s=&threadid=666), in which I said: Found this snippet at wardsauto.com: "As a result, the new engine meets Europe's Stage IV emission standards, while achieving an estimated 23.5 mpg (10L/100 km) in city driving, up from RX-7 levels of just more than 18 mpg (13L/100 km). Mazda expects to raise fuel economy another 30%, to 30 mpg (7.8L/100 km), in 2005. And by expanding the intake port area, the engine runs smoothly at 9,000 rpm — already a rotary hallmark."

The best I EVER got with my 7 was 23. zoom44 10-01-2002, 08:19 PM Originally posted by khoney If the RX-8 gets over 30 highway I'll eat my shorts!

Grimace 10-01-2002, 08:27 PM There seems to be a lot of threats of eating clothes items in here lately. :D BryanH 10-02-2002, 01:45 AM What kind of fuel will the RENESIS require? /me hopes 87 octane will be ok. ;) Sorry if I'm asking too many newbie questions... feel free to tell me to bugger off if this has been covered before too. :p PatrickB 10-02-2002, 09:57 AM Originally posted by BryanH What kind of fuel will the RENESIS require? /me hopes 87 octane will be ok. ;) Sorry if I'm asking too many newbie questions... feel free to tell me to bugger off if this has been covered before too. :p Good question. Older non-turbocharged RX-7s did just fine with regular unleaded, from what I understand, while turbocharged variants ran at higher compression ratios, and so needed premium gas. We're all hoping that regular unleaded will be fine. :) wakeech 10-02-2002, 10:02 AM that's true... even though the compression ratio in the turbos was less than the NA's, the applied compression under boost was pretty high, so with that heat you needed the higher flashpoint... anyways, this car has a what, 10.*:1 compression ratio?? i haven't read a spec sheet for a long time.... i know that most econo four-bangers run 10:1 compression ratios for the most part these days, and thrive on 87-89 octane fuel (higher flashpoints acutally HARM these engines...) i suppose that the 8 won't need anything beyond the high 80's as well... |
