Toyota GT-86 official specs out! (including MPG)

[cossey]

if it is to JIS standards then it is half a tank of fuel and no driver (same as SAE standards) the German DIN standard is 90% fuel tank, the EEC standard (EU) is DIN with 68kg driver and 7 kg of luggage.

Given the 1250kg I would expect it is to JIS so wet but without driver. the GVW is 1470kg not 1450 so you have 220kg or 485lb for all the occupants and luggage. That means with just 2 guys going to a trackday with a spare set of wheels and a few tools you will be way over the limit.

I cant get google translate to translate the entire table; but from what i understand (and what im the most interested in) is:

MPG: 12.3 km/l = 29.17 MPG (combined im assuming)
Gross vehicle mass (limited): 1450 kg = 3196.7 lb
Vehicle weight (limited): 1250 kg = 2755 lbs

Not quite sure what the difference between gross mass and vehicle weight is..

Discuss:

another point due to the test cycles a JC08 test will give a lower mpg value than the CAFE standard the conversion is roughly 25% so a CAFE value of 36.5mpg

Prius is rated as 32.6 km/l in Japan, which equals to 77.22 mpg.
Prius is rated as 50 mpg combined in U.S.
29.17 mpg * 50 mpg / 77.22 mpg = 18.89 mpg

You can offset 20lbs of weight quick with a set of Enkei RPF01
compare to stock wheels.

your math makes sense but...i REALLY hope this isnt the case.. that will absolutely break the deal for me.

The upshot is that the limiting factor for the GVWR is most likely the stiffness of the springs and dampers (and possibly brake pads, fluid and/or cooling) rather than any structural weakness. So anyone with aftermarket suspension bits and high temp brake pads would be just fine.

Testing standards for hybrids are probably very different between the US and Japan. I previously estimated it at 23/31 mpg.

Unsprung weight doesn't count.

irrelevant since you can do that to any car.

you can offset 20 pounds of weight even faster by removing your spare tire :/

i found this pretty informative website that shares conversion from different test cycles...
http://www.unep.org/transport/gfei/a...s.asp#Japanese

From there actually, i can see that the japanese usually underrate their cars by a factor of 1.2~1.3 (keep in mind american measurements are labeled CAFE)


Looking at the JC08 testing chart vs the EPA testing chart, its clear that the JC08 uses alot more hard acceleration and city driving...
Below is the japanese test cycle


and below is the EPA City and Highway test cycle

Its pretty clear that the japanese tests have ridiculous amounts of idle time lol. Thats probably why the prius is rated so high - it has that auto shut off feature.

different cultures/cities, different needs; and the fuel test cycles show that.

Japan is more crowded with a smaller need to drive fast, whereas most parts of north america have less cars, more space = faster speeds and less idling.

i think its safe to say that this chart is more realistic for a non hybrid car...

So a conversion from JC08 to CAFE (epa combined) would be JC08 * ~1.2 or 1.3 = CAFE.
Thus with 29.17 MPG, JC08, we get ~35- 37MPG EPA ratings.. ... hopefully

Nonesense. Just look at the new Porsche 911 and Boxter.

this car to at least offer 32mpg like the GTI.

I'm pretty sure without AWD Subaru engines will get comparable mpg's to other engines with similar size and power output. For example my 09' Forester with AWD, 2.5 liter gets the same mpg rating as a 09' Honda CRV with AWD, 2.4 liter. Honda inline 4s are known for getting good milage right?

im 165 5'10 my gf is 115 5'3 and my two kids are under 6 years old and kids dont weight much.. lol shit i didnt pass 100 pounds till i was in middle school, we are all very fit, very athletic

[no_name]

I can't believe you can only put 440lb in the car. My Accent weighs under 2300lb and it's GVM is over 3400lb. 1200lb difference and only 106hp on tap. I've traveled (short distances) with 6 passengers and a trunk full of luggage.

Ah, I've got an 11 and 7 year old and I'm not sure what they weigh but I'd have to guess around 100 pounds if not more for the 2 of them together.

It's' not really an issue though. Not exactly a family trip car. I'm sure the girls would rather hop in the van with the DVD Player and room for the dog to move around. :P
