Got my STi - initial comparison to 350Z

Well, got my STi on Friday. Its a silver 2005 STi with only 12,000 km on the odometer that I purchased from a Lexus dealer in Toronto. I hammered the dealer on the price and got the car for $36,000 CDN (the car retails for $47,000 CDN new), which I think is a pretty decent deal for what is essentially a new car. I think they were sitting on it for a while; they left the info sheet stuck to the windshield and they orginally had it listed at $43,900.

My other car (now the wife's car) is a 350Z 6-spd. To be honest, I was a bit nervous about getting the STi as I was unsure how it would compare to the Z. I love the Z, but the winter/wet road performance was really limiting my fun. Full throttle in 3rd on a wet road will cause the rear to start wiggling and engage the VDC.

I didn't have too much of a chance to drive the STi yet; basically drove it home, parked it, and left for the cottage. I didn't do any hard cornering yet, but did do several WOT runs up to readline, some highway acceleration, and acceleration from a stop.

So far, I can say the cars are very.....different. I need to drive the STi more, but so far I can't say that the STi is better than the Z, or vice-versa. Probably the biggest thing I am trying to get used to is the power delivery. The power delivery on the STi, to me anyways, is very non-linear. BTW, this is my first turbo car.

With the Z, you get a strong push from low-revs, with a slow progressive build up to 6000 rpm, where power starts to drop off before redline. Also, with the Z, hitting the gas in the lower gears gives you an instant push.

The STi, by comparison, is somewhat soft below 2000 rpm, seems to pick up power between 2000 and 2500, where suddenly the car lunges forward and I'm scrambling to grab the next gear as I'm at readline. To be honest, while accelerating, I felt like I was trying to keep up with the car. From 3000 rpm on, the car swings through the tach so fast.

The STi also pauses for a second when you stop the gas, and then hold on. I realize this is the nature of turbo cars. Something I wasn't expecting is a slight "bog" between shifts during hard acceleration. The first few times I did WOT 1-2-3-4, I thought the TCS was kicking in before realizing the STi doesn't have traction control.

It reminded me of doing a 1-2 or 2-3 shift in the Z with the TCS on. The TCS in the Z is quite aggressive, and it cuts the gas if you chirp the tires on shift, causing the engine to bog for a second before allowing full power.

I also noticed on the STi that high-rpm shifts cause the rpm's to jump slightly, as if there was some throttle hang programmed in. I might need to adjust my clutching slightly. Not sure if that's that's a turbo thing, or its a emissions throttle hang thing. The Z does not require this, and I can bang off very rapid shifts.

Dry road acceleration wise, I'd say peak acceleration in the STi is harder (faster). The Z doesn't accelerate as hard, but it accelerates more evenly over a wider rpm range.

Around town, I found myself in 5th gear in the STi where I normally would be in 6th in the Z. The Z has the down-low torque to be tooling around in 6th at 1500 rpm (the VQ makes something like 200 ft-lbs at just off idle). 6th gear in the STi didn't come alive until I hit the highway at 120 km/h, at which point power in 6th felt similar to the Z.

Driving wise, I didn't get to do any hard cornering. The STi seems to corner about as flatly as the Z. The Z's steering is bit heavier. I did notice a very mild tugging of the steering wheel under hard acceleration in the STi. Not really torque steer, but I could tell the front wheels were doing some work.

Interior-wise is really personal preference. The Z feels more like you are "in" the car; you sit low and the window sill is high. The STi is a more traditional driving position. Seats in the STi were very comfy and grippy. Steering wheel in both cars is nice and fat.

My main beef about the interior of the STi is the placement of the gauges relative to the steering wheel. I like to drive with the steering as low as possible, and in the Z I have the steering wheel set to the very bottom. When I do this in the STi, I find that the top half of the tack is completely obscured by the steering wheel, so I had to raise the wheel back up. In the Z, the instrument cluster moves with the steering wheel, so its not an issue.

Anyhow, as I get used to the car I'll start pushing it harder and be able to give a better comparison.

I'll post a few pics later.

hey congrats! im sure once you drive the car more and more and recognize what it's capable of you'll fall in love.

as far as the slight pause of when you mash the throttle, it might be bacause the sti has "throttle by wire" which means it's electronic. my mom's lexus has this too and when i first step on it in that car it hesitates for a split second too.

also, i remember reading here that the reason the rpms jump when your shifting is because of the vaccum the turbo causes. regardless this is normal on the STi.

lastly, id like to commend you on the fact that you came in here and didn't just say how the sti is amazing (not saying it isn't) and actually did some good comparison.

Great post, thanks for sharing. I'm looking forward to more comparision information as you become more familiar with the STi.

That was one of my initial gripes too. I think part of the issue is the smaller diameter wheel used on the STi. I figured that seeing the cluster was more important than wheel position so I raised the steering wheel. It's been about 6 months now and at this point I have to say I don't even notice anymore.

Again, congratulations on your car and I hope you enjoy it. And if you are going to drive it winter you *definitely* want to get some more appropriate tires! The stockers are really, truly, summer-only.

I have had both the Z and the STi (I traded the Z though, but for the same reason of all-season driving, plus I needed a back seat with a new family). Agree whole-heartedly with your comparisons so far.

First, WRT Throttle-by-wire, all cars have this now. The Z had it as well, so that isn't the reason. The difference is the amount of torque and power available at lower RPMs. The Z was very responsive down low, but that is the nature of a 3.5L V6 vs. 2.5L H4 turbo. However, you will also notice that if you drop gears in the STi into the 4-5K range, it will have MORE acceleration feel than the Z.

As for driving, I found I was shifting a lot more in the STi with the gearing ratio, but once I got used to the car, it easily squeezes out more fun and power than the Z. Also, for cornering, the STi is much better in the turns. Especially the 2006 with the directional acceleration. You can be at a stop light, turn the wheel 45 degrees, and stomp it, and it will hold grip immediately into the circle. The Z??? It would have started into a doughnut right away.

If you haven't launched the car yet too hard, you may think you sacrificed acceleration a bit. But once you line up, rev it up a bit, and let'er rip, you will notice a HUGE difference in favor of the STi.

Finally, agree with note about steering wheel. I hate driving with it high, but with it low, it covers the entire cluster.

Heheehe, never have the Sti under 3K rpm's period. Its like a Honda VTEC in that fashion.

No worries. I'm going to get some Hanook Ice Bears this week and mount them on the stock rims, and get some Rota Torques come the spring.

My comparison of a 350Z to an STi is as follows........





































































There is none. :D The STi owns. :naughty:

Actually, they're both nice cars, but I can't get over the rear of the 350Z. Other than the rear, I like the Z.

Sweet cars. There are just too many Z's out there that I didn't even take a look at them before buying my STi. I would say you are going to love the STi more anyway, can play hard with the car anytime of the year.

One thing I absolutely can't stand about the STi is that it doesn't have a telescoping wheel. It makes it very difficult to find an ideal driving position. I feel like I'm either crowding the steering wheel and don't have enough room for my legs and feet, or I'm sitting back too far to be able to adequately steer without feeling as I'm really fighting with the wheel to turn.

Obviously, when driving "spirited," if you sit back too far, it takes a lot more effort to turn the wheel, and place the car where you want it. A telescoping wheel pretty much eliminate this issue. Not to mention, with the manual seat adjuster, it seems like there's too much space between "notches" in the seat track. Again, I feel like I'm either too close to the steering wheel and don't have leg room, or I feel like I'm sitting too far away from the steering wheel.

I understand that things like this add weight, but I'd really prefer some sort of change. A seat track with more "notches," or even a manual telescoping wheel (like my a VW GTI) would do wonders for comfort.

I think Nissan definitely had a cool idea with the moving gauge cluster, but I found it sort of tough to get used to when sitting in the Z.

Nice garage...if you ever have a hankering for the Z, just trade the wife for a couple days ;) (Also, nice work getting a wife that can drive a stick!).

I can't say I notice any "bog" between shifts...2-3-4 is just pure pushed-into-the-seat fun when I'm clicking off the shifts. Maybe you just need to get used to how the STi shifts?

nice review. i am thinking of selling the sti for a Z. they are a blast. went to a Z show here in PA, one of the biggest on the east coast. Saw a Twin turbo Z setup and loved it. The Z is more "business refined" IMHO. Interior is nice and has good potential. The 35 aniversary is 300 hp stock which is nice. I am really having a tough time here deciding.

A Z was definately a possibility for me when I was doing my research & thinking about what to buy. However, despite the Z-club being a classic club to belong to, the heritage of the Z, and the sexy looks, it was very impractical for my tastes--no rear seat space, a rather small/shallow trunk space, etc. I drove my old roommate's Z, and I always felt like I was going to blow the engine up, as I think it started to redline at 6K. I felt like I was constantly having to shift, just to really get on the car.

Are there any jap cars with telescoping steering wheels?

Only cars that I've seen with one, are germans. BMWs and Audis for that instance. But no jap cars ... At least Acura don't have one... or do they ...
My old BMW's wheel didn't tilt or telescope - one size fits all mentality :lol: Granted, it was an '87.

I remember sitting in an older BMW M car and the wheel didn't tilt either (can't remember if it was a mid-'90s E36 M3 or a '91 M5 that I noticed this in). It was still a fantastic driving position IMO - and I'm 6'2".

I'm content with my STi's tilt only wheel :rolleyes:

Only the very low RPM range may feel weak, otherwise at 2700 things start to move very fast in the STi.

350Z Track Edition was the car I planned to buy in the first place, and I agree it's a lil more linear on the acceleration, but I found the STi easier to drive as far as the driver seating position and shifter.

Second, I found the power to be much better.

I also hate the seat adjustmen, I think if I ever get in a accident ill get stuck because my legs are so close. I would move it back but then im to far away... Drive it hard before you get your winter tires on, I hate mine for daily driving. I really feal I took the edge off of my car.

Got back from the cottage last night and did a couple hours of driving with both cars back to back and got some further insight. The roads were a bit damp so it was nothing too crazy, although it did highlight the STi's strong suits.

As I'm getting used to the STi, I'm liking it more and more. Driving the cars back to back, the STi definitely has more punch and has quite a bit more torque. Lag didn't seem so bad this time around.

I was sad to lose my Xenon's (Canadian STi do not have Xenon because its illegal in Canada to have driver controlled lights) but the high-beams on the STi are unbelievable. Very nice.

One thing I absolutely love is AWD. As I said, the roads were a bit damp yesterday but the STi did not care one bit. In the Z, you are always mindful of the road conditions with regards to flooring it, especially when going around corners at low speeds. I caused the TCS to kick in a few times in the Z and felt a little wiggle of the rear, where as the STi is just "Go man go!" Its pretty intoxicating.

Something I hadn't noticed Friday is that the STi is geared way lower than the Z. Doing some spirited driving along the same road last night, corners that I was taking in 3rd in the Z (putting me at about 4000 rpm), I had to take in 4th in the STi. Likewise, on the highway, 120 km/h in 6th gives me about 2500 rpm in the Z, but more like 3000 in the STi.

I think this is why I felt a bit overwhelmed by the car at first; it seemed like I was just trying to keep up with the car and always had to shift. The Z is more of a long pull; you hold each gear longer.

One thing that I prefer in the Z is the steering ratio. The steering is much quicker in the Z, and you can jump to the next lane with only a small turn of the wheel. The STi requires larger inputs by comparison.

Sound-wise, inside the Z you are more aware of that glorious exhaust sound but the engine is fairly muted. I roll the window down in the summer just to hear that. In the STi its the opposite. You are more aware the thrumming of the boxer engine and the turbo whine. Both cars are pleasant to listen to though.

One interesting thing both my wife and I noticed is that the Z feels faster; by which I mean you have a better sense of how fast you are going. In the STi, every time I look down I am going 20 km/h faster than I expected.

One unpleasant surprise is fuel economy. I was down to half a tank with only 160 km on the odometer. At this rate, I'm going to get about 350 km on the tank. I know I've been driving it hard, but jeez-louise. I routinely get 550 km per tank on the Z, and I don't baby it.

This is a great thread. I saw a 350z driving right next to me on the freeway yesterday and i was wondering how the STi really compares (and also if i could just flat out take the Z).

About the Z and STi engine / exhaust sound. Don't worry too much about that. the stock system is very muffled and i was pretty shocked when i first got my car how much power it had with very little noise. That all changed with turboback exhuast (and no cats too). So if youre missing that H4 sing... get a nice 3" TBE and youll be very pleased with the rumble.
