Basing the real gain on 1/4-mile trap speeds. Trap speed scales with the cube root of power. Multiple C and D road tests had the old car at 95mph, multiple tests of new car have it at 101mph.
205hp * (101/95)^3 = 246hp
Or using the tried and true hp/trap speed equation, hp = (trapspeed/234)^3 * weight,
1st-gen: (95/234)^3 * (2800 + 175) = 199hp
2nd-gen: (101/234)^3 * (2840 + 175) = 242hp
Or basing it off of dyno results of 212.5 rwhp (210-215), scaling by 1/0.87 = 244hp, vs. my old car dynoed at 179rwhp, /0.87 = 206hp
Dunno why they underrated the new car, but all evidence indicates they did! I picked up 5mph on the straights at most of the tracks I go to this past year with the new car vs. my old '17. At Watkins Glen I picked up +10mph (130mph vs 120mph) day one of event there! I think we had a tailwind though, on day two it was only +7mph...
For sure the new car is a LOT faster than 228hp vs. 205hp would suggest...

On the steering front, and not to counter my own post, I have to compare the BRZ steering with the 2008 Z4 MCoupe that I briefly had (and hated)! The car itself was a joke; tiny wheelbase, wide tires, no suspension, and far far back seating position made you feel it was about to swap ends on any corners with the slightest bump.

Ha! Short wheelbase and way way aft seating position just in front of the rear tires are some of the things I really miss about the old 240Z! I almost got an ND2 to replace my '17 BRZ for this reason and much lighter weight. But as only car needed *some* practicality and BRZ is station-wagon compared to Miata!

But the hydraulic steering was amazing... so much feel and feedback. (Engine was good too... although the shifter was very rubbery.)

Reportedly BMW have lost the plot on steering feel since then...

My 23 BRZ steering does not give that immediate feedback at the wheel, but the car doesn't need it either... it handles so much better, especially on imperfect roads. I can drive the BRZ much faster on deserted canyon roads, and the limiting factor is logic not terror. Still nice to know the steering can compete with cars that cost 10x as much!

Hell yeh! Prefer the last-gen's over my '23, but still prefer new BRZ's steering over my old highly-lauded 987 Cayman...
