2015 Wrx stage 1 vs 2013 Wrx stage 1... Which is faster?
A couple years back I had a 2013 WRX that only had a Torqued Performance stage 1 etune on a completely stock motor. This car was fun and "fast" for what it was. A few months back i purchased a 2015 WRX and I am now running a BrenTuning etune on a completely stock motor as well. At first I thought the FA was much quicker than the EJ, so I dug up some of my data logs from when I was logging with the 2013 and looked at some of the acceleration times. When comparing them to my 2015 times, the 2013 is about .40 seconds faster 40-90 mph, and about .35 seconds faster 60-90 mph. All my datalogging have been done on the same stretch of road, in 3rd gear, and the outside temp within 10 degrees of each other. Does anyone else feel the same way? Or have insight? Kind of a bummer to have taken a step backwards.... Please chime in...

not sure how else to look at it. if .4 seconds is significant to you then yea, you ****ed up. shoulda got a mustang. however, if youre not a professional racer then it doesnt matter.

measuring a .4 second difference and .35 second difference on a data log is not a step backwards. if your only judge on performance is 3rd gear pulls... this is not the car for you. not sure how else we can "help" you feel better about your purchase. There is a lot of info out there showing differences from older to newer generation, it is what it is.

I believe the 2013 WRX is lighter than the 2015 WRX, correct? For example, my '13 only weighs around 3,180 lbs. Also, I believe with the 5speed, the gears are slightly taller which proves beneficial in a straight line pull.

While your data may be accurate, there are always variables (outside conditions, same road, tires, etc). The EJ has a powerband which makes the car feel much quicker than it is. Power comes on late and stays late. The FA has a more linear powerband, spools quicker and drops off quicker. The VA is a much better chassis than the GR. Neither car, without substantial work, will ever be "fast".

Your talking two different motors with two different setups, butt dyno may feel a tad different. Like stated above, the characteristics of both motors are different. My 15 actually feels more responsive then my 05 sti. Personally, I feel what these tuners are doing with the 15's is pretty unbelievable. Could always trade is back in for an older 13 if it matters that much.

It's the tune that is the difference. Get a dyno tune and then compare. The FA should win out.

Right. It's not the fact that they have two different engines, different transmissions, different C/O Drag, different weight, different tires, different outside conditions. It's obviously the tune. A tune by someone who slaps the same tune on everyone's car (Eric @ TP) vs one of the most well known and reputable tuner/e-tuner (BT) who takes the time to modify the map in a way that is safe and gives good power.

I am not that surprised by the numbers, when you think of the characteristics of the motors. The 2015 is really more centered around developing more torque early on and reducing turbo lag. Down low, the car feels more responsive but there are trade-offs and clearly the car starts to run out of steam in the higher RPM ranges where the previous generation did not.
If your goal it to go faster, you need to start considering stage 2. I mean what is your goal here? If your butt dyno is happy with the 2015 at Stage 1 I would say leave it there and maybe focus on fine tuning things like the suspension and shifter. For me, I always focus on the suspension first before I start adding more power. RCE springs and a proper alignment can really change a car. |

There are a few things to consider when comparing datalogs of two different cars. Weather, consistency of driver, tires, etc. .4 of a second is hard to justify speed between two cars. Unless you know the exact temps, humidity, and density altitude, comparing datalogs of two different cars with a long gap of time between the two is invalid.
If you bought the 2015 to be faster than your 2013, stock for stock, that is an incorrect purchase. There are so many variables here that make this impossible to compare. Even having low tire pressure can change the time it takes to get from one speed to the next. Wind could have been blowing against you as well. Do you see what I mean? Just my .02 Kris |

I didn't choose the 15' for just straight line speed over the 13'. There are so many up sides to the new model. The suspension and handling is a huge improvement, as well as the updated interior and gauges. I also like the new styling of the front end, as well as the rear. The 6MT is nice too, and I do like the quick spool of the FA. I was just hoping it would be a little faster. I guess its time for some TGV deletes, and a Down pipe.

I had my '15 WRX tuned by Bren and I have my current '15 STi tuned by Bren, both stage 1. While I have no facts or concrete proof to back up my claims, the STi feels quicker. It's possible that is attributed to the shorter gearing, higher revving and peaky powerband. Both cars made very similar numbers, 270/290 WRX 270/300 STi. |

Regardless of which is "faster" I'm happy with the new WRX in so many ways.

Good to see people sharing their info. I only used numbers as a reference because I truly do not have any evidence lol. I am very happy with my 15 for reasons besides power. Can't wait to get my j-pipe though and an etune most likely.

I'm not saying that Eric does "bad tunes". I'm saying that Bren has probably done more 2015 WRX E-tunes than most other tuners and knows them very well. The main point of the post is to make note that it's two different engines, years apart, with different tuners and I'm sure different ambient conditions, not to take a shot at your tuner.
