Electrical systems: Introduction
For the new BMW X5 (E70) the following objectives have been set by Marketing and Design:
- Clear positioning in the MCL+ vehicle class (size, price)
- Development of the BMW interpretation of a SAV, based on driving dynamics, handling, agility, design and passion
- Installation of additional 3rd seating row without compromising other vehicle characteristics (weight, exterior, proportion)
- Increase of the variability and practicality compared with E53 so that multiple uses can be supported
- Extension of the accessory equipment program to meet the increased customer expectations in the MCL+ (e.g. Active Steering, adaptive drive, tailgate lift, reversing camera)
