The power figure is pure speculation based on the availability of the FA24 and the B48 in the Supra.
Honestly my biggest worry is that with 260hp will come a ~3100lb curb weight, and that would kill the spirit of the 1st gen.
A porker is precisely what the Supra 2.0 will be and its where the GR86 fills in as an agile alternative. Its for the average person. The same type that bought a base, non-turbo MKIII or MKIV Supra. Great way for Toyota to milk the Supra for all they can.
the new supra doesn't even have a toyota engine, so i don't think it's relevant... they should have released the car with this 'upgraded' engine from the getgo, but i am almost certain they had some bpa with bmw that didn't allow them to do so [same reason why the supra comes with the older version of idrive].
of course, the gr86 will not have a toyota engine as well, but at least they co-developed the fa platform...
exhaust upgrade + e85 + tune will easily push it to 300+ rwhp, so i am not worried about the power... shedding weight is much more difficult.
the current gen clocks the scale at ~2800 lbs., which is great in this day and age, imo... hopefully they can keep it under 3000 lbs. for the upcoming version.
Japan always gets the cool stuff for cars. Toyota Gazoo Racing is partnering with McDonalds to give out a GR Supra Happy Meal toy. They're even making a collaboration movie!
If this is successful (which I don't see why not) they should do the same thing with the GR 86.
