Replying to: seanwms6 (Jul 13, 2006 3:48 pm) This press release lists the MS Atenza's power rating as 200 kw (268 hp). Seems like a 10 kw / 14 hp difference would be the result of something other than different methods of measurement.

Replying to: seanwms6 (Jul 13, 2006 4:33 pm) Oh well; I think I'll stop flogging this dead horse. It's all conjecture anyway until Mazda releases the official specs. Perhaps they're a bit gun-shy after the release of other models with what turn out to be inflated hp numbers. |

Replying to: rorr (Jul 13, 2006 2:03 pm) I don't know what type of fuel they use in outback land, but I do know that a higher/lower quality fuels have been known for power spec differences (again, as seen in the world of racing). Then there is air quality such as altitude, air temp., humidity, etc., that will change a vehicle's characteristics from day to day or sometimes in the same day. Seems too trivial especially without knowing at least some of the above.

Replying to: chacobleu (Jul 14, 2006 7:25 am) Yep. Not sure about 'critisms' of our gasoline however (can't necessarily directly compare Octane ratings either since Europe (and Australia) uses the RON ratings (Research Octane Number) while we use the average between the RON and the MON.) Otherwise identical gasoline is rated 4 to 5 points lower under our system than the European ratings. From what I understand, the new MSP3 (like the MSP6) in the U.S. will 'require' 93 octane (measure under our system). Yes, it should run okay with lower octane fuel, but won't make as much same power (due to the ECM adjusting the timing). It's quite possible that Mazda decided that there is adequate availability of 93 octane fuel in the U.S. to tune the MSP6 for 274hp. The flip side is that the equivalent fuel may not be AS available in Australia so Mazda tuned the engine for more of a midgrade blend. I haven't seen the fuel requirements for the AU market MSP3 or MSP6, so I don't really know. Yes, atmospheric effects will certainly change the power output. And yes, this is all pretty trivial. I guess we're all just passing the time until we get some more real news (or driving impressions) regarding the Speed3.

Replying to: seanwms6 (Jul 13, 2006 8:11 am) FYI: 248 hp is incorrect. It came from http://www.autoexpress.co.uk/news/motoringpreviews/200846/mazda_3_mps.html. But Oz Mazda says the spec is 190 kw or 254 hp, so maybe the 248 hp is just for the euro-spec MPS. |

Replying to: kronogoose (Jul 17, 2006 6:47 pm) Looks to be a fairly positive review. What I'd REALLY like to see (at some point) would be a comparison test between the Speed3 and the other current hot hatches in the segment (VW GTI, Civic Si, Cooper S). Also, I noticed mention that the engine torque is 'managed' in the first THREE gears, rather than just 1st and 2nd. That's WAY too much 'management' IMO. Does anyone know if the DSC system can be turned off (completely or to some degree)? Also, I wonder if the torque management through the first few gears can be similarly turned off?
