Lately, we visited the corporate’s Built-in Security Centre in Pune to witness the rigorous means of security testing of its automobiles, which are sometimes praised with the time period “Tata ka loha,” for his or her sturdiness. Earlier than a automobile earns the correct to put on the Tata Motors badge, it endures a multi-step ordeal, together with the precise crash check through which the automobile is rammed right into a deformable barrier at a pace of 64 kmph. That, nevertheless, is only a small a part of the method.
Crash testing at Tata’s facility: The method
The motion begins on the Servo Acceleration Sled Facility. Right here, the entrance cabin construction of a automobile (together with dashboard parts and security options) is positioned on a big mechanised sled that accelerates it. The aim is to simulate real-life situations, analysing how sudden acceleration and fast stops can have an effect on the occupants inside, in addition to how the parts will react in such situations. Initially, it’s finished as laptop simulations after which in full-size scale, simply as they’d be carried out within the last automobile design. There’s a complete lot of sensors to file knowledge on deceleration forces, structural integrity, and the effectiveness of security options like airbags and seatbelts.
Furthermore, it is more cost effective than an actual crash check and permits for a number of trials. If the producer is not proud of the outcomes, the automobile will not advance to the precise crash check stage.
Lastly, after a number of digital simulations and sled assessments, the second of reality arrives – the precise crash check. Throughout our go to, it was the brand new Tata Safari SUV that took the centre stage. The mannequin has already obtained an ideal 5-star score from each, the GNCAP and India’s very personal, the Bharat NCAP.
For this check, as you would possibly already know, dummies take the passenger seats and the automobile is rammed right into a deformable barrier. What you won’t know is the truth that every of those dummies comes at a monumental price of as much as Rs 3 crore; that’s roughly the on-road value of 20 base-spec Safari SUVs in opposition to one dummy. The great half is that these dummies are reusable and solely require put on and tear upkeep over time. These dummies, outfitted with over 42 sensors every, file essential knowledge throughout the affect, thus giving worthwhile insights into the affect on occupants, similar to forces skilled and potential accidents sustained.
The ultimate act
The crash space is illuminated by highly effective lights simulating pure daylight. Positioned across the zone are a minimal of 10 high-speed cameras capturing the crash from numerous angles exterior the automobile, together with 5 inside cameras recording the occasion at 1,000 frames per second. As soon as every part is ready, the automobile is propelled in a 200-metre-long tunnel utilizing a motor and hits the barrier at 64 kmph, leading to a loud, explosion-like sound (which was heard aloud within the corridor we had been seated in).

Following the crash, engineers collect and begin gathering the info. The automobile is then transported to a separate facility for additional evaluation earlier than it’s scrapped. Talking of the Safari that crashed proper in entrance of our eyes, the general construction of the SUV remained largely intact, minus the impacted crumple zone. Moreover that, the dummies too, regarded in good situation, because of the protection luggage.
Tata Motors has advocated prioritising security by making certain that every one its automobiles have top-notch security scores. It’s no coincidence that 5 of its automobiles boast a 5-star security score from GNCAP and the remaining have a minimal of 4 stars.
