The manufacturer appears to be focusing on affordability.

The gains come mainly from higher battery capacity, as efficiency increased only slightly.
The new model year brings a driving range of almost 300 miles and significantly improved efficiency.
The VinFast VF9 Eco is rated at 330 miles while the VF9 Plus is good for 291 miles.
The fuel economy barely exceeded 50 MPGe, which explains the necessity for a large battery.
The range number is good, but efficiency is significantly lower than in the case of the Tesla Model Y Performance.
The all-wheel-drive system does not reduce the range by more than several percent.
The results match the Dual-Motor Rivian R1T pickup.
The efficiency is noticeably better than in the case of the Quad-Motor version.
It has a bit more range than the NCM-powered version, but is marginally less efficient.
