The 1.4L in the new Golf looks pretty awesome on paper, and probably in real life too.
114g CO2, 140HP, 250nm @ 1500rpm

More paper numbers:
188g CO2, 3L (I6) turbo, 320hp, 450nm - BMW M135I (manuall, Automatic is 175g CO2)
188g CO2, 2l NA, 200hp, 205nm - GT86/BRZ
131g CO2, 1,6 turbo, 136hp, 220nm - BMW 116I (F20)
136g CO2, 1,6 turbo, 184hp, 240nm - Mini Cooper S

Dyno comparison:
BRZ (green) vs Cooper S made be Perrin on the same dyno, + BMW 116I dyno results hand drawn by me (in yellow) taken from another wheel dyno in Norway. The 116I have about 20% more HP than it should have, and a ton more torque than it should have. Not a very big surprise considering it is a downtuned 118I, and that is almost the same engine as the Cooper S.

(For the record, I own a Cooper S, and test drove 116I and GT86 the same day. My butt dyno says these real life dyno looks pretty right)

Compared to modern turbo engines the numbers from the 86 are not impressive in terms of output vs fuel economy.
And they are even worse when comparing real life power compared to underrated modern turbo engines.. On every day driving- below 5000 RPM a 136hp 116I beats the 200hp 86 with good margin. Compare 4000rpm!
yeah, the character of a 116I is very boring, and the GT86 is fun at high RPM. But that is not the point..

I still desire a GT86, but im not impressed by its efficiency or engine numbers.
Is it because it is a bad NA? No, but modern turbo engines are just very impressive..
The M135I probably have 350 flywheel hp and 500NM from a 3L 6 cylinder engine with same emissions (at least on paper) as the FR-S/BRZ.

You can get this performance (and sound) out if an engine that is more fuel efficient than the FR-S/BRZ!
