It's definitely a massive improvement in the exterior design imo, I thought the mk8 was too subdued and boring looking after the mk7.5.
Interior is still a lazy design slapping an iPad on the dash without trying to integrate it into the dash. Gear-nib? is still ridiculously pointless and should've just been added to the steering column like in Mercedes. But at least they listened to all the negative reviews and didn't add back normal climate controls.
Seat bolsters still look very low as well.
In regard to a MHEV or PHEV, why resist it? Tune the engine for the top end and let the hybrid do the low end, and you'll get a far better car that's more exciting for the corners! You can't enjoy these cars properly anymore as you get going too quick, and it becomes dangerous, yet a 1 litre rental pinned to the redline barely getting to 40 is great fun.
