Anyone check it out yet? I know it's not competing with RCF, but a 2015 RCF and Q60 are similar in price. Last time I checked, tuners have cracked Nissans Ecu. There is lots of potential with the VR. I might have to take a trip to the dealership.

Yeah I ran in to check one out...very stunning. I priced it out to where you could get one almost loaded for $57,000. The 0-60 I have read is also 4.5 secs.
Tempting when you can buy a new one for $57,000. as opposed to getting a used 2015 RC F for 57,000....but I still do like the lines ion the RC F better

400 hp, 350 torque, 3900 to 4000 pounds. Seems like they would have upped the power a bit, especially with forced induction in a car that can hit mid $60s loaded. Any real world data on performance? The new S5 comes in at 3560, has 350 hp, 370 torque for the same price as Infiniti. The new 440i is also an attractive option with similar performance for less $$$.

airlaird

Yeah, I agree, I expected more H.P...but I am guessing they will introduce a bigger engine in an IPL model as they had with the G37. But yes, this is a tempting option for less $$
twin turbos, and adaptive dampers..I am kinda waiting on a MT or Car and Driver test to come out...Of course the 2017 F now has dampers... .

where did you get that weight? I'm only able to get the 2.0t off their website and it says 3727

Looks like the engine is underrated also. Playing BMW's game. http://www.infinitiq50.org/forum/sti...8657?_k=qjgisg

It pretty much has to be underrated if it's the same weight as the RC F (assuming 3900-4000) with a similar 0-60 time. Unless it's geared low for drag racing.

It gets similar 0 to 60, but only trapping 109 for the Q50, which is 387x lbs. the seven speed is holding it back

Yeah, I don't look at the Q60 Red Sport as being in the same class as the RC-F or M4. This car is more in line with the 440i and S5 with the comparison you provided.

The biggest tell tale sign of this car being a performance class below the RC-F is the complete omission of a LSD in the Q60 Red Sport. Infiniti is probably saving their track-oriented version of the Q60 as an IPL model as airlaird stated.

Off their website. List the RWD at 3,862 and AWD 4,024.

Haha, let's wait and see what actual performance is as opposed to internet hype from a single dyno read from a single car which can be very inconsistent. I have seen dyno numbers on same cars (my cars) vary greatly. Dynes are great for tuning, but even then can be manipulated if you have an agenda.

Stillen's conclusion/conversion would have the RCF at 500hp and 410-440 torque based the lowest RCF pull on I saw on here with a quick search.

Forced induction cars tuned by manufacturer for acceleration #s will undoubtedly have an edge 0-60 and up to 1/4 mile speeds over RCF NA engine based on torque curve and area under the curve. Don't need under rating conspiracies for that. In this price range, our NA V8 is a dinosaur compared to FI, albeit a sweet dinosaur, that will be at a disadvantage acceleration wise to FI engines with less peak output #s.

Wifey brought a Hellcat home for the week end last night. Drove it to dinner last night, but road was wet . . . Excited to see what this thing is made of.

DougHII

I dunno. One can only wait until actual test #s come out. If you are solely focused on 0-60, 1/8th or perhaps 1/4 mile, the RCF will be at a disadvantage to a car equipped with a FI motor.

Perhaps at 49 and after closed course racing 30+ plus years, things like 0-60 are so unimportant and unimpressive to me. Never understood why anyone would even let it bother them if someone on the street is a tiny bit quicker them in rolling street race race. That is silly and take ZERO talent or skills and people with no skills should keep it off the street. So if it ain't about compensating for something else in one's life, what is it truly about? I doubt anyone on her can actually feel a seat of the pants difference between 4.5 and 4.3 0 - 60 and candidly, these numbers ain't crap now a days anyway.

airlaird

Dough your right..lets see what tests show. I am 54 and 0-60 is very important to me...why?.....PASSING power. Not racing some kid on the street..but simply passing power either to avoid a collision or getting out of the way. This passing power equates to lower end torque to pass a vehicle which I believe the F lacks..
And yes, this model should be in the same class as the RC F If the specs show that...reviews will tell. Again, this Forum is about the RC F..a car I will buy when I retire..unless something as good comes out..like a new SUPRA ;-))

When I was referring to the Q60 Red Sport being a class below the RC-F and M4, it was in terms of handling dynamics, not straight line performance.

i didn't know that about the lsd. . I still have my 1st gen coupe and it came with a viscous unit. . I would also like to see a few more Dynos. I agree with the car's competition. I was only making a comparison based on price in relation to a used 2015 RCF.
