BMW i3 Euro NCAP Crash Test Video

My previous post discussed the four out of five star rating the i3 received from the Euro NCAP crash tests. Above is a video provided by the NCAP which shows the various tests being performed on the car.

Additionally, BMW offered a press release today, seemingly as a response to the 4 star overall rating, with the intention of reminding customers that the i3 did sores a perfect 5 or 5 in the actual crash:

The BMW i3 achieved the highest rating of five stars in the Euro NCAP crash tests governing occupant protection and child protection that coincided with its market launch. As expected, the electric car matches the performance of the best conventionally powered vehicles in its segment in the area of passive safety. The Integral safety concept covers everything from collision avoidance to Intelligent Emergency Call and also meets requirements above and beyond Euro NCAP.

Its revolutionary new vehicle concept allows the BMW i3 to offer customers not only smile-inducing driving pleasure and outstanding environmental performance, but also top marks in terms of safety. An integral safety concept put together for the BMW Group�s first all-electric model includes everything from driver assistance systems focusing on collision avoidance, via passive safety to the Intelligent Emergency Call function � and complies with all global accident protection standards.

The aim of BMW�s integral safety concept is to achieve an optimum combination of active and passive systems that is geared to real-life traffic and accident situations. Among the active measures included as part of this concept are preventive systems which help the driver to avoid accidents. The Driving Assistant Plus system available for the BMW i3 includes both Collision Warning and Pedestrian Warning with braking function. Unique in the segment, this system helps � in urban traffic, in particular � to either prevent collisions or significantly reduce the intensity of the impact. Meanwhile, precisely defined load paths, generously sized deformation zones, a passenger cell whose strength allows it to serve as a survival space, and electronically controlled restraint systems with precisely interlinked functionality team up to optimise occupant protection if a crash is unavoidable. Likewise unique in this segment is the Intelligent Emergency Call function with automatic vehicle location and accident severity detection � a standard feature in the BMW i3. This system, which automatically establishes a telephone link with a call centre, thus cutting down the time it takes for the rescue services to be alerted, earned the BMW Group the special Euro NCAP Advanced Award from the European crash testing institute in 2010. As things stand, the standard testing process still does not include the Intelligent Emergency Call function in its assessments. Legal requirements stipulating the inclusion of a system of this kind in all newly registered vehicles across the EU will not come into force until 2015. 

The effectiveness of all the passive safety systems in the BMW i3 was analysed during the car�s development process in numerous crash tests conducted by the BMW Group�s accident research specialists and in cooperation with independent experts. As part of this process, all the accident scenarios referred to for vehicle registration processes and consumer protection tests around the world � above and beyond Euro NCAP testing � were taken into account, including an impact by another vehicle against the rear of the BMW i3 and a roll-over situation.

An extremely rigid passenger cell made from carbon-fibre-reinforced plastic (CFRP) and the precise interplay of its restraint systems allowed the BMW i3 to record outstanding results for adult occupant and child occupant protection in the Euro NCAP crash test. The testers noted an exceptionally low risk of injury in both front and side impacts, as well as in the Pole Side Impact test. Particularly striking here was the low degree of deformation in the CFRP passenger cell, which also enhances the effectiveness of the restraint systems.

BMW i3 Earns 4 Out of 5 Rating in Euro NCAP Crash Tests

The i3 scored very high marks for passenger safety in all crash tests, so why only a 4 of 5 star rating?

Much to the surprise of quite a few people, the BMW i3 earned a 4 out of 5 rating in the Euro NCAP crash tests. BMW has been proudly proclaiming how incredibly safe and strong the car is due the the rigid carbon fiber passenger cell. In fact it was so strong, they were able to eliminate the need for a proper B-pillar and offer the coach style door setup. So why not a top score? Well like anything, the devil is in the details.

Most people don't want to waste time reading crash test scores, they usually just look at the star rating. If they see a five star rating, they assume the car is as safe as it should be and anything less than a 5 out of 5 can be viewed as a failure on the manufacturers part to produce a car that's as safe as possible. So what went wrong here? We've been hearing how strong the CFRP passenger shell is and how incredibly well it will protect the passengers in the event of a crash for a couple years now. In fact I personally had a lengthy conversation with BMW board member Ian Robertson about this and he went on and on about how incredibly well the i3 did in their internal crash tests, so why now did it not do well? The truth is, the car actually did very well in crash tests, in fact it did actually score a 5 star rating in crash tests for passenger protection, but the overall combined score fell a couple points under the threshold for 5 stars.

What held them back? When I tell you you'll either laugh off your seat or shake your head at the foolishness that allowed them to miss the coveted 5 star rating. Ready? Here goes: For some crazy reason, there is no rear seat seatbelt warning system on the i3. Most cars today have this feature so that omission cost the i3 points.  That, plus the fact that the speed limit notification is optional in most European countries (that is the feature that displays the current speed limit of the road you are driving on and it's a standard feature on all US i3's) conspired to give the i3 an extremely low score in the "Safety Assist" category. Those two oversights caused the overall score to dip just below the 85% needed to achieve a 5 star rating. The fact that they were rated 4 of 5 stars really had nothing to do with how the passengers fared in the crash tests, because the i3 actually had high scores in that area. In fact, the i3 achieved a higher score for passenger safety than a Chevy Volt, which did achieve an overall 5 star rating. (see graph below for comparison)

The BMW i3 compared to the Chevy Volt in the Euro NCAP safety rating

This is a pretty substantial mistake on BMW's part in my opinion. While the car tested out to be very safe in crashes for all of the occupants, the 4 out of 5 rating will give the casual observer the impression that it may not do well in crashes. Could it be BMW thought the crash scores would be so high they would overcome the low score in the Safety Assist category and still average out to be 5 stars? Whatever the cause I can't help but think this was a major faux pas. This sets the stage for an interesting and highly anticipated crash test rating for the US when NHTSA and the IIHS get their hands on some i3's in the Spring.
