Funny you mention start/stop because I was very glad this technology was not implemented into the FT86.

I've been in BMW's where, if you come to a stop and put the car in neutral, and take your foot off the clutch the engine stops. It restarts when you depress the clutch pedal again.

My thinking is this: If I want to shut off the engine while sitting, I can turn the key and do it myself. I wonder how others on the forum feel about this?

On an automatic, I'd probably be OK with it, but definitely don't prefer it. On a manual, I wouldn't buy the car.

seeing as the mustang v6 guys are reporting high 20's for mixed driving, this doesnt impress me too much. hell my focus does better with very similar power numbers (2.0 duratec, cosworth intake mani and other bolt-ons). 22/30 for the manual is about where i thought itd be though so not too surprised.

cant wait to see what this does in real world driving

By shutting off and starting up the engine every time (in the city) defeat the purpose of saving gas? I'm not too sure if that's even the point of having the start/stop concept in some cars.

Either way, I agree and happy that Subaru and Toyota left out the start/stop.

I could only see extra fuel wasted in an older car with a carb, where you need to give it some gas to start. on a modern engine theres probably little/no waste like you said

True, you can do it yourself, but typically an auto start-stop system has an integrated starter-generator to make starting quicker, be more durable than a starter which is typically made to be as cheap as possible, and provide greater braking regeneration (and therefore regular power generation capacity as well). It's better hardware, which of course comes at added cost but it's not much more than a traditional alternator/starter setup. I think we may start to see it standard soon.

Hmmm. I'm surprised at the disparity between the manual and automatic highway mileage figures.

However, the EPA's mileage testing approach is very complex. Car and Driver visited their facility and wrote an interesting article. You can read it at:

No joke! My STi is rated at 16/22, so I'm pretty happy with these numbers.

Well, since the mustang is rated at 19/29 for the manual v6, I don't see any reason why the numbers from the BRZ should be worrying. It should be quite easy to best the EPA numbers in this car.
