SAFETY AND SERVICE.
![Page 22: ENERGY AND RESPONSIBILITY....PR = press shop BS = body shop PS = paint shop AS = assembly PA = assembly parts DM = drive module aluminium structure PL = plastic parts painted CFRP](https://reader034.vdocuments.us/reader034/viewer/2022042909/5f3a6f905d56a16e0a298fff/html5/thumbnails/22.jpg)
WHY LIFEDRIVE ?
Many advantages
– Easy to create variants.
– Weight reduction by lightweight design.
– Specific structure to house the battery.
– Optimum integration of eDrive powertrain
– Low centre of gravity - good rollover resistance.
– Optimum safety concept.
![Page 23: ENERGY AND RESPONSIBILITY....PR = press shop BS = body shop PS = paint shop AS = assembly PA = assembly parts DM = drive module aluminium structure PL = plastic parts painted CFRP](https://reader034.vdocuments.us/reader034/viewer/2022042909/5f3a6f905d56a16e0a298fff/html5/thumbnails/23.jpg)
FRONTAL IMPACT.
Impact energy is distributed optimally through the Drive and Life modules. High-strength CFRP passenger cell remains almost free of deformation: - Survival cell remains intact. - Doors do not get jammed. Rear-mounted motor allows low crash pulse and therefore low occupant loading in a frontal crash.
![Page 24: ENERGY AND RESPONSIBILITY....PR = press shop BS = body shop PS = paint shop AS = assembly PA = assembly parts DM = drive module aluminium structure PL = plastic parts painted CFRP](https://reader034.vdocuments.us/reader034/viewer/2022042909/5f3a6f905d56a16e0a298fff/html5/thumbnails/24.jpg)
REAR IMPACT.
Impact energy is absorbed mainly by
the Drive module.
Impact-resistant rear end structure
protects high-voltage components.
![Page 25: ENERGY AND RESPONSIBILITY....PR = press shop BS = body shop PS = paint shop AS = assembly PA = assembly parts DM = drive module aluminium structure PL = plastic parts painted CFRP](https://reader034.vdocuments.us/reader034/viewer/2022042909/5f3a6f905d56a16e0a298fff/html5/thumbnails/25.jpg)
SIDE IMPACT.
Honeycomb-elements in the sill absorb the impact energy and divert it over the Drive module.
High-strength CFRP passenger cell allows major reduction in intrusion and therefore provides a good basis for occupant protection.
![Page 26: ENERGY AND RESPONSIBILITY....PR = press shop BS = body shop PS = paint shop AS = assembly PA = assembly parts DM = drive module aluminium structure PL = plastic parts painted CFRP](https://reader034.vdocuments.us/reader034/viewer/2022042909/5f3a6f905d56a16e0a298fff/html5/thumbnails/26.jpg)
HIGH-VOLTAGE BATTERY (HVS) IMPACT.
Intrusion of pole is stopped before reaching the HVS. Optimum position of the HVS outside the deformation zones.
![Page 27: ENERGY AND RESPONSIBILITY....PR = press shop BS = body shop PS = paint shop AS = assembly PA = assembly parts DM = drive module aluminium structure PL = plastic parts painted CFRP](https://reader034.vdocuments.us/reader034/viewer/2022042909/5f3a6f905d56a16e0a298fff/html5/thumbnails/27.jpg)
RESCUE.
“[we] had the opportunity to confirm in
standardised cutting tests that the rescue of
passengers from a crashed BMW i3 is similar
to a conventional vehicle.”
Munich Municipal Fire Brigade, March 2013
![Page 28: ENERGY AND RESPONSIBILITY....PR = press shop BS = body shop PS = paint shop AS = assembly PA = assembly parts DM = drive module aluminium structure PL = plastic parts painted CFRP](https://reader034.vdocuments.us/reader034/viewer/2022042909/5f3a6f905d56a16e0a298fff/html5/thumbnails/28.jpg)
SAFETY.
The BMW i safety is on eye-level with conventional BMW.

SERVICE.
The BMW i total repair costs will be on eye-level with conventional BMW.
