There was nothing I really didn't like about our Rabbit in '07. It was the pre-tuned version as well at 150hp/170ft.lbs.

We achieved then the highway rated fuel economy at 29-30 MPG with the 6sp auto. It had decent power, a good tone off idle, good sound higher. You could really hear the timing chain though.

It was a very quiet car, very good on fuel even with my wife's super short trips.

I don't know why people discount it so much it is a lot better than the 2.0 they offer now.

We both own a great sounding four cylinder in what is effectively a very fancy econobox package.
Pricey when new, but economical in daily use.
The 318i sounds really good at anything over 4K.
I know that I'm comparing apples to oranges.


Yeah, but it isnt the 3.0L TT in my 135i. It isnt the 4.3 in my truck.

Thus is my point. Sure the M42 has a snarl, but many dont like those kinds of sounds. IMO the 2.5 is neither better or worse than anything else. It is just different.

And given that it appears that the SW has been changed so a 5MT 2.5 now returns 33 highway, I'd say that is pretty darn good for as easy as the car is to drive around town.

No overly jumpy first gear like a toyota or need to take it to 7000 RPM to be moving like a honda.
 
Interesting, I wonder what the cost difference between a head from a VW dealer and a Lambo dealer is?

This might be a good way for the Lambo guys to save a buck come rebuild time, but I doubt they are a direct bolt on swap that share the same part numbers.

At the very least it makes the boy racer Jetta owners happy.
 
Maybe it's not that bad....but it's not that good either.

It has similar numbers to a '95 Acura TL 2.5, that came with an inline 5 cyl. It looked like an old CB7 Accord's F-series engine with another cylinder grafted on. The Honda engine isolated the imbalance better than VW did.

And I did drive it. I've actually driven the Rabbit 2.5 and Jetta 2.5. The extra displacement is welcome vs. the Civic and Corolla. That's not the problem...the problem is that Kia, Mazda, Mitsubishi, Subaru, and at the time, Chevrolet, all had similar displacement 4cyl engines availiable (standard in the Impreza) that did everything the Volkswagen's 5 did at least as well, usually better.
The Mazda has better driver dynamics, the Subaru has all-wheel drive, the Kia is cheap, and the Chevrolet? You had to get the Sport package (labled SS for a couple of years) to get the 2.4 ecotec, but who doesn't like an ecotec?
I didn't drive the Lancer with the 2.4 I may have made an error in assuming that the Forte' SX 2.4 would be exactly like the Lancer. I didn't like the shifter in the Kia. It was ropey and weird. Worse than the Subaru's

I think MotorTrend summed it up best when describing the 2.5 L5 in the Passat:
The 2.5 Passat is for people who don't care about Volkswagens, or cars in general.
Yes, I'm aware that the Passat is a larger car but it still sums up my feelings

At least in my neck of the woods, only women buy non-TDI jettas.

What imbalance? I just dont get it, our 2.5 is super smooth at all points, and quite quiet too (backed up by the C&D test).

C&D didnt think that the other cars did everything better... We dont either. And none of them have the utility or rear seat space that the rabbit does. I can sit perfectly comfortable in the rear seat of the Rabbit at 6ft 5, with perfect legroom. We've fit some BIG cargo back there. There is a utility that isnt had in small sedans.

I dont find your arguments for what the other cars are as very compelling. I just dont get why the 2.5 is such a whipping boy. Give it 35k miles of it of real world use and it really isnt a bad car for commuting around. The only place where it isnt my top choice is long-term highway duty - it would need a 6th gear for that... And given the new software, a 6th gear would surely yield 35 MPG, which is VERY competitive, especially given the power level.

Im no racer!

I just think it is weird. Some of the parts in the engine are actually made in Italy.

The C&D test? The one that ranked the Mazda3S above the Volkswagen?
http://www.caranddriver.com/reviews/comp..._s_sport_page_4
Granted, those were 2010s. The models I drove were '06-07s (except the Kia. I drove the Forte' much later. I did strongly consider a Spectra5)

And none of them have the utility or rear seat space? Seems like the Mazda had the largest cargo area.

After driving all of those, I had really intended to buy an '07 Mazda3S but I found the 6S for less. The 3 was much better looking in it's earlier generation.

I liked the TDi Jetta and really liked the GTi, but they were almost as ridiculously priced as the Civic EX was. (Civic EX was the worst offender in needless dealer markup and dealer add-ons. I coud drive a 3S off the dealer lot with sunroof, leather and Bose for $18K or a Civic EX with cloth for $21K) At least with the Volkswagens, you are getting a turbocharger and/or a diesel for the price.

The 5-cylinders just didn't do anything for me. Where the Mazda's MZR would start to pull above 4000 rpm the Rabbit and Jetta seemed to just make more noise.
And neither was as well appointed as the competition for the price.

But it's all subjective. I'm sure there are people who drove the 3 and the Civic and chose the Civic because the 3 was "twitchy" and "noisy".
 
I love the new Jetta, but find it really odd that thew Australian market only has the 118TSI and 103TDI engines, no naturally aspirated options, whereas the american market has the 2.0 and 2.5 NA. If given the option I'd take the 2.5 NA but the 1.4 twin charged does have some benefits. except the turbo I'm not a big fan of.

Did you even look at my link? What I was talking about was the 2008 test.

OK, let's look at the 2010 test, using the revamped golf which was a modest redesign to make the vehicle cheaper to build. Great.

All right, where is the wonder of the Mazda versus the VW? First let's look at the reviews:

Lows: Only five speeds, spongy legs, not much frill at this price.


OK, solid comments and issues. The lows were kind of weak, Ive said the engine should have a 6MT, and frankly, no frills is a plus as it makes for a good lifecycle cost for those of us who keep our cars a long time.

Originally Posted By: Mazda:

Lows: The engine lacks verve, the back seat blows, and wipe that grin off your face.


OK, so despite your claims of all the great space in the 3, they say the back seat blows? Yet Im saying that my 6ft5, 260# torso fits comfortably in the back seat of our rabbit and my brother's 11 golf TDI for long distances. Engine? I thought all the 4-cyl engines out there could do everything that the 5-cyl did... Yet C&D is saying that the engine lacks verve? Oh yeah, C&D said the VW had broad torque as a PLUS.

What else should we compare? Mazda is louder at WOT. Slower 1/4 mile, worse EPA highway mileage than the 2.5 (without its 6sp and now as weve seen, the 2.5 returns 33 so it is handily better).

The mazda only returned 0.01g better on the skidpad than the VW, and while it was faster in the lane change, let's not forget that the Mazda had $$$ 17" V-rated rubber, while the VW had economical 15" rubber on it. Funny too is that in the review I linked to, the 08 rabbit, also shod with 15" rubber, did that same lane change that the Mazda "won" in your review at 62.3 MPH, at 62.8 MPH.

Cargo space??? Well, the mazda 3 has 17 cubic feet to the golf's 15. Ill give you that. But the rear is only 43 vs 42, and the overall length of the Mazda is 177" vs 165" for the golf. So that sounds to me like the Mazda may actually be LESS space-efficient.

Yeah, youre not making any arguments that persuade me much. Why not look at the reviews objectively? Seems that folks want to hate the 2.5 just so they have something to hate. Im just looking for best value, and Ive still not seen any real argument to persuade me to prefer another car over the rabbit/golf. TDI over 2.5, sure, and we would have bought a TDI if they were available when my wife was shopping. I still dont see a better alternative...

I'd rather put my 1911 in my mouth and pull the trigger than buy a VW. Heck I owned two of them already, and I wish I did that before I bought them.

If my choice was between a nice new Jetta and a pair of Nike sneakers to walk, I'd take the Nike's!!!!!

So? If all the manufacturers, VW included, had 2.4-2.5 liter engines that performed relatively similarly, who cares if VW's has 5 cylinders instead of 4? If you give Subaru a pass despite the relative complexity of the boxer engine vs all the inline engines, why does VW not get a pass for just having an extra cylinder?

I'd think that the 5 cyl would have an extra bearing to support the length of the extra cams and cranks... Wouldnt that distribute forces better ensuring superior longevity??? Just thinking out loud.

That kind of makes sense in theory but in practice I'd bet it doesn't make much difference, considering the glut of long lived 4 and 8 cylinder engines, and for that matter 6 cylinder engines with fewer bearings.

I just don't see why people expect some extra goodness from the 5 cyl 2.5 when compared with various 4 cyl 2.5s given it's the displacement that makes the power, not the cylinder count.
 
Right. And at the same time, all the servicability aspects are great because it is an inline engine. Its all there to work on.

I don't expect "extra goodness" from VW on it's I-5. I'm looking at it from the other direction: if displacement is the largest influence on power, why not use a 2.5L I-4 instead of a 2.5L I-5? Inline-5s are inherently imbalanced, and are also dimensionally longer, adding a packaging challenge to the engine bay. I'm not seeing the reason for using 5 cylinders here.
 
Yet it fits fine in the engine bay of the golf/rabbit, and there is no imbalance or harmonic. It isnt a screamer, but it does not have to be.

Why try to force every powerplant to look like a Honda? Id prefer to not have to take my engine to 5000 RPM every time to make full torque.

And we rarely, if ever, see 2.5L I4 engines for whatever reason. LOTS of 2.4L I4s though...

With a 5-cylinder engine, you get a power stroke every 144 degrees instead of every 180. This results in power stroke overlap which I think is supposed to give the engine more torque at the low end and run somewhat smoother at midrange rpms, but it is also the source of secondary and third order vibrations at other rpms.
