1. Family Vehicles: Space and Safety Are Essentials
1.1 Key Metrics for Rear-Seat Space

| Midsize SUV | 900-950 | 1-Child Families | Toyota RAV4 |
| Full-Size MPV | ≥1000 | 2+ Children + Elderly | Buick GL8 |

1.2 Child Safety Features
ISOFIX Anchors:
Minimum Requirement: 2 sets (best positions: behind driver & front passenger).
Hidden Design: Some German models require seat cushion removal (e.g., Volkswagen Tiguan).
Convenience Features:
Rearview baby monitor (Li L8).
One-touch child lock (Hyundai Custo electric sliding doors).
Pitfalls to Avoid:
Some coupe models (e.g., Volkswagen CC) have limited rear-facing child seat space due to front seat interference.

Departure Angle: 20-25° (Tiguan L: 21°).
Hardcore Off-Roaders:
Tank 300: 33° approach angle.
Land Rover Defender: 900mm wading depth.
2.2 4WD Systems & Use Cases
| 4WD Type | Operation Principle | Best For | Fuel Efficiency Penalty |
