-
For anyone who finds the Dolphin a bit low and the Atto 3 slightly bigger than needed for tight city parking, the BYD Atto 2 slots right between them. Here is how the dimensions and platform stack up:

1. Key Highlights & What Stood Out to Me
BYD has released official specifications for the BYD Atto 2, slotting cleanly between the Dolphin hatchback and the Atto 3 SUV:
- Dimensions: 4,310 mm long × 1,830 mm wide × 1,675 mm tall (2,620 mm wheelbase).
- Platform: e-Platform 3.0 with CTB (Cell-to-Body) Blade Battery—making it the first compact B-SUV in its class with structural Cell-to-Body construction!
- Interior: Conventional luxury Ocean/Dynasty console with physical buttons, crystal gear selector, and 400L–1,340L versatile boot.
2. Closer Look at the Specs & Hardware Packaging
Technical Parameter Official BYD Specification & Benchmark Vehicle Architecture e-Platform 3.0 with Structural LFP Blade Battery Pack Cycle Longevity 3,000 to 4,000+ Full Charge Cycles (>93% SOH at 120,000 km) Bi-Directional Power 3.3 kW V2L Standard + Native V2G / V2H Grid Support Warranty Coverage 6-Year / 150,000 km Vehicle & 8-Year Blade Battery Warranty 3.

With physical buttons on the centre console, a boxy 400L–1,340L boot, and Cell-to-Body rigidity, who else is considering the Atto 2 as a daily city runabout?
