Awesome find krew! The rear end of the sketch is really rough, so they don't know exactly yet what it will look like.
I can't translate the thing, but tidbits I was able to discern:
- Talking about the LC and TNGA, the 4IS is obviously using GA-L.
- LC F and IS F are mentioned as well as the rumored 4.0L TT V8. Sounds like that means we could get a next-gen IS F with the rumored TT V8
- The UX is also oddly mentioned
- Both the 2.4L 4 cylinder turbo as well as the A25A engine are both mentioned. Different engines for different markets, or a sign that the 2.4L 4 cylinder turbo is related to the A25A?
- Listed dimensions for 4IS:
Wheelbase 2870mm (113 inch) ?
Length 4730mm (186.2 inch)
Width 1815mm (71.5 inch)
Height 1425mm height (56.1 inch)
For comparison, current 3IS dimensions:
Wheelbase 2,800 mm (110.2 in)
Length 4,681 mm (184.3 in)
Width 1,810 mm (71.3 in)
Height 1,430 mm (56.3 in)
Current 4GS dimensions:
Wheelbase 2,850 mm (112.2 in)
Length 4,879 mm (192.1 in)
Width 1,840 mm (72.4 in)
Height 1,455 mm (57.3 in)
LC dimensions:
Wheelbase 2,870 mm (113.0 in)
Length 4,760 mm (187.4 in)
Width 1,920 mm (75.6 in)
Height 1,345 mm (53.0 in)
There is a question mark though about the wheelbase as I can't read Japanese, and can't confirm if the wheelbase is indeed matching that of the LC. If true though, that's a noticeable length and significant wheelbase increase for the 4IS. That's also an identical wheelbase to the LC and extremely similar length. The IS getting LC dynamics...that would be huge. Also signifies decreased overhangs for the 4IS. Bigger wheelbase than the 4GS as well. So according to the measurements, size-wise the 4IS won't totally match the GS, but it gets closer to GS size than before. Of course, if we do get a next-gen GS in the future, it will be sure to grow in size.
