The GVM grew from 3280kg to 3380kg while the fully fueled weight is 2830kg. That leaves only 550kg for passenger and payload. So you can forget about building an overlanding rig with this one.
The Chinese market model lost 41kW (55hp) to comply with N6B emissions, which lies somewhere between Euro 6 and 7. So we can expect at least that amount with Euro 7 and EPA 2027. So the 2027 Tundra will be 249kW/334hp and LX600 will be 264kW/354hp.
Light-duty passenger vehicle NOx emissions for N6b: 35mg/km, Euro6e: 80mg/km, Euro7: 20mg/km, EPA 2027: 35mg/hp-hr
