'How much more Awesome can Awesome get?'
I just can't see how Toyota is going to make a better product than the 200. Cosmetically they can change it alot but other than improving seat comfort, I don't see a drastic area for improvement? The chassis will be close to same size, power delivery can't be increased by much, handling can't be improved by that much (KDSS did wonders).
My guess would be technology and economy. Clearly the 8 speed transmission they added for 16 did nothing to improve mileage, so the engine would be the next logical place for savings. I love a big V8, but most manufacturers are replacing them with smaller displacement turbos to boost economy and I can't blame them. I'd be ecstatic to see a nice diesel, but with the scandals of late we likely will never see Toyota put something like that in a niche vehicle. The tech even in the 16+ is still dated compared to peers, so I could see them upping the ante there to keep justifying an $80k price. My coworker has a new A4 with the tech pack and virtual cockpit and it feels about 10 years (maybe more) ahead of my 2014 in terms of the tech.
