Am I crazy for wanting a 2015 Chevrolet SS?

Saw two of these on I-10W yesterday. A turquoise blue and a black.

What's the average MPG? Serious question, I looked up the s600 on fuelly and found a couple there around 16~17, on premium gas. I see around 18 on fuelly for your car.
LOL, I am looking on fuelly at notes for fillups. People often indicate premium and brand in the notes. Check out the only note in this guy's log.

Average fuel usage isn't all that great. I average between 12 and 14 MPG.

Is that because of driving style?

 

[AdamK47]

I moved closer to where I work and don't use the highway anymore. The car will most likely do better once it gets a better tune. The base tune runs a little rich.

 

[AdamK47]

Only 6 psi of boost. The stock LS3 MAF housing is also restrictive at this point. Should be well over 600 RWHP with some other minor tweaks.

002 = Stock
005 = Headers + CAI
008 = Supercharger (and supporting parts) + CAM
013 = New intake tube + MAP sensor + SC belt

 

[KentState]

Something looks off with those numbers. My CTS-V was putting out around that much HP, but nearly 600 ft/tq and with lower pulley, intake and long tube headers.

 

[AdamK47]

It's not bad for only 6 psi of boost and the LS3 MAF housing being a restriction. You can see it kinda flattens out at 3500 RPM. I'm done with the car for a few months. Then I'll probably do more stuff to it. A couple more pounds of boost with a different upper pully and a new MAF housing will get it well over 600 RWHP.

 

[AdamK47]

I looked at some other Cincy Speed dyno videos and some of the HP/TQ ratios seems to be about the same. I guess it's how they dyno tune it. Mine was between 560 and 585 hp and between 480 and 500 tq on various runs yesterday. There was a Procharged C7 there last month with 600 hp and 520 tq.

 

[KentState]

Doh, my bad, the CTS-V was running a lot more boost to it's not easy to compare. You can see that the TQ is higher than HP (not sure where the last dyno sheets went after the last build). While my the centi on my C7 is putting out more HP than TQ.

 

[AdamK47]

That's a great deal more compared to the measly 6 psi I'm running. A CTS-V with the LSA has a much lower compression ratio of 9.1:1. It's 10.7:1 on an LS3. Just 2 psi more will help me greatly. I'll need to increase the MAF housing diameter to accommodate it. That will eliminate the restriction with just 6 psi and allow for more airflow. I'll probably have an entire intake tube fabricated that includes the MAF housing and connects from the throttle body to the air box. That should put me at 650 rwhp.

Adam, what's your opinion of the SS as a daily driver? I'm most interested in your opinion of the interior, the 6-speed manual and clutch, the infotainment system... things like that. Obviously with as much power as yours is making it's quite fun to drive, but what about the creature comforts?

 

[AdamK47]

It would make a great daily driver if you aren't too concerned with gas mileage. With the car stock I averaged 14 mpg around town and just over 20 mpg highway. I don't do highway much anymore though.

The only reason the car is available in the US is because GM was contractually obligated to Holden to have the cars made for US sale. That's why there are only 2,500 of them a year and why there is absolutely zero marketing for them. There are only three options that you can choose from when buying the car. Other than that the cars come fully loaded.

I would say the SS has one of the best interiors GM has ever made. Certainly for the Chevrolet brand. Everything about the interior has changed for the better over the previous VE Commodore (Pontiac G8).

The clutch and shifting feel great. The transmission is a TR6060 which has been and is still used in many performance cars. Good luck finding a manual for sale close by you.

The infotainment system is good. I wouldn't say great. There is quite a bit of lag between screen transitions. That would be my major gripe there. It has a good layout.

The ride in the 2015 is a much more forgiving with the inclusion of magnetic ride control. The 2014s didn't have it and were a bit stiff.

Performance is good stock, but could be better. A conversion to LSA is a popular mod for these cars and can get you between 500 to 600 RWHP easily. Stock is between 330 to 380 RWHP.

I wish we could get the HSV variants in the US. Their last line of Commodores are all LSA supercharged. https://www.youtube.com/watch?v=mwbFe5uHavM

If you do get one, you have to be prepared for the "What is it?" or "Is that a Malibu?" from just about everyone. It's fun the first few dozen times, but after about a thousand times it will wear on you. Even those that think they are automotive enthusiasts don't have a clue about these cars.

Awesome, thanks for the feedback. My plan is for it to be my fun/summer car and use it almost like a daily driver in the summer. I'll keep my Fusion for winter driving and for the times where the SS is out of commission while I work on it.

I actually found the exact one I want only about 50 miles away... Black 2015 with manual transmission and sunroof. I have an appointment to see it Thursday... I'm considering leaving work early to go see it today and potentially snatch it up.

I'm really trying to talk myself out of it being such a bad idea to get it going into the winter, but I'm really tempted to just go buy it since it's exactly what I want. Especially since I'm not likely to get much a price reduction from MSRP and the 2016 models are due to come out in the next few months with the dual mode exhaust. I'm planning on using that to try to get an extra $1000 off the price - buy today with no dual mode exhaust with the understanding that I'll want to replace the exhaust system. I dunno... probably won't work... but can't hurt to ask...

Wow. Beautiful car. I'm a die-hard Ford fan, but this is the first Chevy in a long time I'd consider owning. My mom's looking for a new, fun-drive car with a manual, definitely going to show her this one.

 

[AdamK47]

Bumping this thread. Miss the car.

Doug DeMuro did a video on cars not liked in their time, but are now desired and worth quite a bit. Chevy SS is on the list.

I've found low mileage manual transmission cars for between $55K to $60K. Bought mine new OTD for $48K in early 2015.
