Subaru powered Toyota FT-86 Concept

So the 2010 VW GTI they DYNO'd put down ~ 200@the wheels which translates to roughly 235hp@crank when the typical 15% drive train loss via FWD is factored in.

So the real rating of VW's 2.0l turbo I-4 is closer to 235hp/240ft-lb.tq. This makes sense when you consider the GTI's curb weight ~3200lbs and acceleration #'s. Still the BRZ / FR-S weigh over 400lbs less and hence have roughly equal power to weight ratios of ~ 13.8:1.

I always thought that it was bizarre that the GTI could run the times it did with supposedly just 200hp but this DYNO result pretty much explains it. The HP/TQ figure VW uses actually turns out to be HP@the wheels. I wonder why they choose to advertise it under-rated so severely like that... Insurance maybe?

This kinda has me wondering about the new Golf R's power rating now... VW claims it makes 256hp/243ft.lb.Tq but seeing how under-rated the GTI's power rating it sort of makes me wonder. But then again they've tested it's acceleration and it posted times similar to an MS3's 5.5 0-60 / 14.0@100 quarter.

So when you consider the Golf R has AWD but a power to weight ratio a bit inferior (12:1 vs. 13.2:1) to the MS3 it's ratings may be about right or perhaps a little under-rated as well.
