OMG how many times did I have to say it??? Totally under-rated. Even conservatively this thing has a 15% total transmission and drivetrain loss. With all the extra shafts it could be closer to 20% (more efficient maybe than a RS4 drivetrain but more shafts/bearings as well). This means the engine is putting out about 560 - 590 crank hp.

Now we know the whole story...

I also just re-ran the power to weight vs. N'Ring lap time regression with 560 hp and found it to be outperforming the linear fit by a mere 1.7 seconds. Previously, we found in the regression thread that is was 25 seconds faster than the model predicted. If the car really had that good of a driver and tires as good as I expect they are the time is ABSOLUTELY NOTHING SPECIAL.

Talk about dishonest and over-hyped....

That being said 560 hp for $70k is amazing and the car is darn fast.

P.S. I think this is worthy of an main topic so I am going to re-post this!
