Nissan Juke...

[Swine]

This car has been flying off of my radar. Looks like a fit/versa competitor with some real aftermarket/hp capability. C&D says it feels nicer then it cost. CVT fwd stock trapped 91mph.

-Starts at 20k, maxing out at 25k with a cvt and torque vectoring awd(wet clutch pack on each rear axle that can lock and dissengage pending a combo of g's, steering angle, speed, etc..effecitively adding power to the outside wheel steering the nose in the right direction).
-Direct injected 1.6 turbo 188hp.
-Base is a cvt fwd, optional 6spd manual fwd only, or a cvt with tq vectoring awd.
-Supposed to have a really snazy interior with g and boost reading on the displays among other nice touches
-C&D's fully loaded 6spd manual fwd with leather and sunroof was 2905lbs(and stickered for 23k). Most compacts these days are over 3k lbs.

For someone looking for a fun, capable, and effecient all round DD. Looks like an interesting car.

Wish i knew more about the motor they are useing. I dont think there is a dif options avail for the fwd models but damn that would be freakin sweat if they did.

The car below isnt my cup of tea but man with the right taste the thing could look ok to.

Ask me how I know you're gay....;)











i keed i keed...some of these micro cars are pretty sweet. I'd rather have a CRZ, but the Juke does have potential.

Get down from there headlights. You don't belong up there.

I am actually intrigued by this car. It seems pretty cool, though Nissan marketing definitely helped with that perception.

[Nsparks]

I saw one of these at VIR last weekend. Pretty intriguing little car. They got to get on the track taking corner workers to there station and zip it around with great success.
There was also a Mazda 2 racing. It went off and hit a wall an hour in. completely smashed the rear of the car and bent a camber arm. The team had it back out on the track in under 2 hours and it made it the rest of the way.

Pretty interesting... sad there is no 6MT + AWD option. Too bad Nissan didn't develop a turbo awd coupe or low slung hatch instead of a crossover :(

[D-Lew]

Somewhat interesting, makes me want to Nissan Puke though. I think the front is ugly as sin, needs a facelift before I would drive it. The rest looks pretty good all things considered.

[zmasterB]

Went to school on it last week..............

Interesting thing......the turbo is about the size of a chick pea, & it runs as much as 26 psi in sport mode.....I've found the boost control solenoid hits 100% duty cycle & just stays there in sport mode, so apparently 26 psi is maxxed the F out, Sport mode=ahhh just let it have it.

Swine, the engine is an MR.......same engine family as the 1.8 & 2.0 used in the Versa/Cube/Sentra. Hopefully it holds up well turbocharged, all I can say is "make sure to change that oil every 3000 miles" ;)

Also worth noting, I'm 5'11"......& when sitting in the back seat, my hair is fairly smushed against the headliner. Sooo your 8 year old kids will fit OK, but your 6' & taller buddies, not so much.


Oh yea, & I also think its uglier than shit :snipe: The crap on the fenders makes me think of wasps or hornets for some reason......& boy does it look better with no headlights in that chop.

[Jess]

ehh, it could be cool. I'd like to see it from a few different angles but I'm too lazy to google it.

[Pegasus_Red]

I really liked the concept, it seemed pretty slick, however the stance sucked friggin Highlanderesque bawls
http://theblogaboutcars.com/wp-content/uploads/2010/07/nissan-juke.jpg

I liked that the fact that the lights were up top and seemed more of an accent. Then some one stepped on the damn thing and the headlights bulged out like stepping on a frog. I really liked the rally esque/old school fog lights and Im glad that they kept them, I actually saw the concepts top lights as maybe turn signals even though they werent orange.

I will never understand the allure of a damn cross over. They just dont make sense to me. Why the hell do this. I mean honestly either get a little 5 door hatch or a two door hatch... need more room... bam get a wagon.

I like nissans approach to the making this crossover esque more fun. I predict this thing to be a hot little seller pocket rocket that the GTI once was and I see this as nissans attempt to try to capitalize on that market that vw has seemed to pwn. Its also trying to keep up with Ford and their eco boost, which I bet my hat we will be seeing that in a focus not too far off in their SVT some time soon.

Nissan needs to diversify their offerings as far as cars go. I am very reluctant to say thought that this will be an instant hit. They have marketed it from the standpoint of a "we are going to sell to male business proffesionals who want a fun car that is sporty, but can go off road, but has a back seat and a hatch, but can handle, but can do both kinda sorta ok, ohh and its turbo charged so tuners are going to hop on this like flies on dog shit etc etc".

Honestly the more you begin to try to slam a design with a one size fits all... it usually doesnt work out. Id rather have something that does extremely well vs something that does a little bit of everything but mediocre. Then again, this may or may not be designed for "car guys", just the car guys that like to pretend that they are car guys and what that look...


And the CRZ pisses me the fuck off... I want just a CRZ with a damn I4 engine FR that is fun, handles well, is light, and I can trick it the hell out and add a fart can. What the hell is all this damn hybrid shit... Batteries can suck my damn bawls. WTF honduh. WTF You havent had a comparable hatch, and the Fit has been great, dont get me wrong, but you missed out on that market... but wait Europe got it? I dont understand it, then again maybe it was to warm the Fit up for the American market, who knows.

Ok Im done ranting.

On the production car/thing the lights up top are only the markers & signals.....the ones in the bumper are the headlights.

I agree.......if you need this kind of vehicle.....uhhh hello what was wrong with a wagon? All this striving to make vehicles safer & more fuel efficient, lets see: Lets take a Versa, make it heavier, jack it way up in the air where the aero is worse & its more likely to roll over......yea, makes sense :tard:

FWIW there isnt room in the rear of this thing with the back seat up to put a cheese sandwich......so humans can't fit in the back & neither can your luggage. This thing is most definitely a niche vehicle........& as if we needed anymore "niche vehicles" in the Nissan lineup, just wait til you see the Murano convertible (no I'm not joking).

As for crossovers, we sure sell the shit outta Rogues.........the most improperly named vehicle in the history of vehicles.


-Grouchypessimisticoldguy out LOL

[Swine]

I was actually waiting on your first post brent haha. Well hopefully the fact that its running 24psi in stock form means the engine has atleast some balls. Does boost pressure have anything to do with engine internal stoutness or is it more the power figure?

As far as what this car fills what needs...see wagon...see wagon with more ground clearance, a bit smaller and sportier, cheaper, and better mpg.

Like a smaller and funkier forrestor xt thats cheaper and gets better mpg and is more "economical" while hitting a younger and more outgoing age group.

I'm betting it runs 26 psi absolute, or about 12 lbs of boost.

[zmasterB]

Yea you're probably right......the instructor kept saying "26 psi" so I was just rolling with it, although that really seemed impossible considering how small the turbocharger is.

If I ever have cause to datastream one again I'll look more closely haha.


As for the engine stoutness Swine, thats what I was alluding to with the "change the oil" comment. MR18's & 20's seem to be very sensitive to maintenance, if the oil isnt changed on time (or at least close) they just eat themselves alive......hell, they blow up before they even get a chance to make any real sludge buildup. I've got one in the shop right now that the customer went 11K on one oil change.......it sets misfire codes due to bad compression loss, knocks, & has so much blowby that the air filter is soaked with oil & it'll blow the oil cap outta your hand if you unscrew it with the engine running.

So as far as I'm concerned, the jury's still out on the reliability of these MR series engines, at least as far as what I've grown used to seeing out of Nissan products over the years.

[Pegasus_Red]

From my understanding, and if my logic is flawed call me the hell out, 26psi in terms of "boost performance" really doesnt mean anything. 26psi from a tiny ass Garret t20 or t25 =/= the boost pressure of say a t60 something. The flow rate is where the true hp lies in terms of the engines capabilities. Now by the reverse logic, and this has been taken from many do it yourself boosters from the old AC VW rule, is that the rule of thumb is around 12psi for safety, and in terms for stock engines you want a turbo that can get you to 12 reliably and efficiently, you dont want a huge honking blower that only kicks in at 7krpms and your red line was back at 4.5k. Once you start getting around that 12 on vw engines... it gets real iffy real quick. Im wondering what the internals of the engine will be. Were they forged? FORGED!!

Now what I would be interested to see is how the car actually accelerates. I was toying around with the idea that if you utilize a small enough turbo that is say constantly sitting at 0 atmospheric pressure, essentially there is no vacuum present, could you in turn actually use a turbo much like a supercharger. But I decided against it because well, I like boost lag to a certain extent, it gives the car two driving personalities, slow poke sam, and lead foot larry. But with Nissian, I like this idea that this could be used similar to a sport mode, like an instant supercharger, then when you turn to economy mode it drops back to normal engine operating vacuum. Now what will be interesting to see, is that with smaller turbos there's always the issue of heat soak, does this thing have an intercooler? Then again if the turbo is water cooled and so on, maybe this wont be such an issue? But as Zmasterb has pointed out, these engines dont like being neglected, throw a turbo in the mix with an engine that is allready maintenance sensitive for the times we live in and this could be a really big risk to nissan.

I wish I could just take aspeed for a class some times.

Correct, as far as hp and tq are concerned the lbs per sqr inch the turbo is producing does not relate to hp and tq across all turbos.

The likelyhood of this turbo actually running 26psi is very low. But if it did would this in anyway relate to stout motor build(as in strong, capable of reliably making higher hp)?

The more it think about it, the more i think "no". A compression stroke in a normal internal combustion engine generates upwards of 200psi depending on the compression ratio. Therefore simply forcing air in the combustion chamber at 26psi would not even approach the stresses that are produced on the cylinder walls and internals that a compression stroke and combustion stroke produce.

So with that conclusion, i guess the amount of hp and tq created on each combustion stroke is the determining factor to whether the internals and cylinder walls hold.

Now correct me if i am wrong, but to your intercooler hose clamps 20psi is 20psi regardless of the turbo...right(same amount of stress on the hose clamp regardless of which turbo is producing 20psi)?

Ok, now we are getting into phizziks...
From my understanding if you have a fluid, which liquids and gasses are fluids, and its traveling through a pipe, pressure drops as the flow rate through the pipe increases. But in terms of intercooler clamps and what not, yes they see that 20psi, all they really care about is the force that the pipe wants to burst off at the connector site, they dont care how many units of mater escape, they care about the amount of force behind each molecule of matter. Now the interesting thing about intercoolers is the pressure drop factor, but thats another issue which is interesting, as air temps cool, the pressure reduces. But back to your idea on the flow vs psi stuff. PSI is just the force in comparison to the materials surrounding the air, the only time you have to worry about it is when you shift, huge ass PSI spike, blown pipes etc = blow off valve.

Now with the question of if the motor will hold 26psi...
Now you are starting to look at break mean effective pressure. But what a turbo does do is actually raise your compression ratio. It dumps more air into it vs the cylinder actually just sucking in air... thats volumetric efficiency. The danger lies when the combustion takes place and that energy puts massive amounts of stress on the walls. Put too much stress by dumping in more air then the cylinders / heads/ con rods / head studs etc can hold when combusted and boom. My bet is nissan has this down to a science with engine... atleast I hope soo.

[zmasterB]

Now what I would be interested to see is how the car actually accelerates.

The response is fairly instantaneous.....almost no lag at all. The only one I've driven had a CVT tho....the gear ratio programming of the trans helps out with "loading" things properly given the driving conditions, a manual one may feel a little different.



it gives the car two driving personalities, slow poke sam, and lead foot larry. But with Nissian, I like this idea that this could be used similar to a sport mode, like an instant supercharger, then when you turn to economy mode it drops back to normal engine operating vacuum.

In the sport mode, the throttle response is enhanced, maximum boost is allowed, & the CVT actually emulates a fixed gear transmission (i.e. it "changes gears", & suprisingly crisply too). In econ mode, the throttle response is literally annoyingly lethargic, the CVT gear ratios remain relatively high, & the boost is reduced substantially unless it sees WOT. So yes, it most certainly has 2 personalities.



Now what will be interesting to see, is that with smaller turbos there's always the issue of heat soak, does this thing have an intercooler? Then again if the turbo is water cooled and so on, maybe this wont be such an issue?

The turbo is watercooled, & it actually has a fairly large intercooler.

Of course combustion temps/ignition timing/flamefront propagation/related stuffs all play into this equation too......its all about combustion control. Unless you have a KA24 LOL....those guys are starting to get splits in the cylinder walls regardless of how well its tuned, or how good it runs @ ~700whp levels due to the lack of cylinder wall thickness, which is a real world study in what you said there. No detonation, everythings good, it just cant physically hold the pressures being generated.

One of the interesting features of the Juke's engine is that it has a notch shape in the pistons, that creates a vertical tumble of the gases in the combustion chamber as the squeezing occurs on the comp. stroke, as opposed to the horizontal swirling motion used in the past. This tumble motion is touted to create a much better atomization of the mixture, & more efficient/controllable burn. Add the direct injection, & thats gotta be one highly controllable, well atomized mixture of gases.

This D.I.G. stuff is new to us......I kinda chuckled when I saw that it makes less than 10ms injector pulse at WOT........but at 2100 psi of fuel pressure :O

commericals of 4 door turbocharged vehicles gets me going.....

The flow rate is where the true hp lies in terms of the engines capabilities.

If you are at the same RPM and the same boost psi you have the exact same volumetric flow rate. It doesn't matter what turbo you have.

The only difference between turbos at a given boost is how efficient they are, ie: how much they heat the air.

So, your mass flow rate can be different at the same boost level, but not your volumetric flow rate.

BTW here's my opinion on this vehicle:
