#22 of 65 Go with manual tranny by samtheman1 May 08, 2006 (7:18 am)
Recently did a test drive in 2.0 and 2.3 manual and auto trannys. If you are getting the auto, I'd really suggest the 2.3 as it has 5 speed tranny and the auto tranny sucks considerable power from the engine. 2.0 seemed underpowered in the auto.   I liked both of the manuals much better. You could feel the improved low end torque in the 2.3 (snappier feel), but the 2.0 was not bad. If you don't know how to drive a manual, this is good car to learn on. Clutch and shifter smooth and easy to use. Go test drive them.
#23 of 65 VVT by grandadturismo Dec 10, 2006 (8:13 am)
certainly, peak 2hp gain isn't much.   however, peak is only part of the story.   if we had Q and HP curves for '06 and '05, we could numerically integrate the Q and HP curves (separately, of course) and see the quantitative effect of the VVT over the entire usable rev range (this, coupled with gear ratios, is why power-to-weight ratios, though valuable, aren't always the best predictor of acceleration). this would give us a better picture of the "numbers". of course, various standing and rolling acceleration times at different speeds and gears would give us an even better idea of the difference (if any).

Replying to: cinzano66 (Apr 15, 2006 10:54 pm) I drove both and felt little difference. I ended up buying a 06 mazda3 i touring with the 2.0. I was told by the dealer there is only 12hp between both engines and isn't worth the extra money, I just put a K&N filter in my 2.0 Replies to this message: ahightower (Dec 30, 2007 2:52 pm)

Replying to: vlstellato (Dec 29, 2007 6:52 pm) I could certainly tell a difference between the two. Not huge, but I could feel it. However, the 2.0 felt plenty powerful enough for me (especially after comparing it to my other top contender, the Mitsubishi Lancer). The added gas mileage and lower sticker price appealed to me more for this purchase - just a commuter car, trying to save my pennies. I'll add a K&N filter when the original needs to be replaced. The 3i Touring package added the key features I really wanted - steering-wheel audio and cruise controls, iPod jack, side airbags, ABS, and 16" alloys. It was a good compromise for my needs. I'm getting 32 mpg and don't miss the extra power and torque 99% of the time.   The salesman also told me that the 2.0 had better reliability than the 2.3, but I haven't really seen anything to substantiate that. He might have just been trying to convince me I was making a good decision, but even if it's just anecdotal, I'll take it.
#26 of 65 Is Larger Engine Just a Rumor? by carjim Jan 01, 2008 (10:53 am)
For the life of me I can't find the source where I read that the 2.3 would be replaced by a 2.5 in the Mazda3.   Perhaps it is a rumor. Ford used a 2.5 in the Contour/Mystique, but it was a six.   Has anyone on the board heard about a larger engine?

Replying to: ahightower (Jan 02, 2008 6:31 am) Thanks a million for the link. I couldn't ask for more confirmation than that.   I will definitely want to test drive one with the 2.5 when they show up. Replies to this message: mazdrvr (Mar 06, 2008 6:06 pm)
#29 of 65 2,0liter is verry good by gib11 Jan 05, 2008 (6:06 am)
t he 2,0liter is used extensively in the MZ6 in Europe ans Asia since 2002, verry reliable. The 2,3liter has more torque than the 2,0liter (150 vs 135)
#30 of 65 engine noise/whine???? by pjade Jan 24, 2008 (7:19 pm)
Just bought a 2008 Mazda3 i touring 4 door sedan. Has anyone noticed a high pitched hum that comes from the left side engine compartment near the fan belt. It is always there but especially hear it when sitting at a stoplight or even if the accessories is on with the engine not running. Can hear it inside the car, but hear it most when standing outside. I talked to Mazda service and they said that this is common on all Mazda3's as it has to do with the electronic power steering - just wondering if anyone else has experienced this? It is kind of odd to consider it normal. Any and all input would be greatly appreciated.

#31 of 65 high pitch noise by nsbio1 Jan 25, 2008 (1:04 pm)
Yes, I also noticed that on my 2008 i Touring. The pitch does change when you turn the wheel, so it is consistent with it being power steering. Supposedly, PS on this car is not purely hydraulic but is electric (I am not a techie). To my ear, it is (barely) audible but it sounds normal to me.   I never actually listened to it from outside the car. Should do it at some point, I guess.
