Mercedes visualizes airflow using smoke streams in wind tunnels, allowing engineers to study exactly how the car’s shape guides air around the nose, windshield, roof, and rear for maximum aerodynamic efficiency. Meanwhile, some Indian brands simply drive the vehicle to Leh-Ladakh if it makes it there, the testing is... considered complete!😃show more

These cars are meant to go fast. In India the cars are expected to be comfortable with good AC so that one can sit in traffic for longer durations and at the same time being fuel efficient.

Am pretty sure Indian car manufacturers won’t be spending as much as Merc but Mahindra is doing similar work at their overseas company -

What's the point of measuring CoD after the design is finalized? Most aerodynamics are designed in simulation. This is just theatrics.

Even after going Leh - Ladakh, Post launch they are full of complaints and issues that even OEMs dont know how to resolve it.. 😂

Indian brands are jugaadu 💀

In real life, rarely there will be laminar flow of air from front, it's always cross winds, wonder how they test that.🤔🤔

I might have missed but what do you think about BMW, Audi and even Volvo in these aspects. Do you think Merc has better drive, stability and safety in these 4?

Best is Volvo!!! 👌🏻

I don’t think it’s safe to assume that Indian brands don’t do that while prototyping. It’s a standard practice now even if with wind tunnel tests.

This is primarily for measuring the Cd, but only this doesn’t necessarily mean WorldClass, right? Please know that Automotive Manufacturers in India too measure Cd of their products including other design aspects along with actual road performance.

U expect scorpio or likes being driven by champaks have any clue on aerodynamics. Naaa

But then why @anandmahindra @MahindraRise and @TataMotors will invest in Wind tunnels when all they manufacture is block box suv’s It just dst serve any purpose to them

Mahindra nuntag nahi karoge paaji 😎😎

Every OEM is using CFD analysis these days.

Test it in production!

Lalaji knows dhandha, cost, sale price and wants maximum profit. That is all that matters here. All simulation done in brain before opening the mouth. Rest is chonchlabaji

Real Test Drive in Leh

Our automakers got research departments?

Our cars are engineered to do well in slow moving unpredictable traffic and overcome leh like roads all while being in budget.

Dang 😳

Tata Motors also utilize wind tunnel test facilities hosted by research bodies such as ARAI (Automotive Research Association of India). They are doing their bit.

So gadi banane ke baad test ho rhi?! Isn't that a waste of money and strategy!

Well said Col. 👍 India is a rich country but inhabited by extra smart industrialists, who know that this population will buy any crap ‘cause “yahan sub chalta hai “.

That is the reason your Benz does not sway sideways when you encounter cross flow winds. I have experienced that on stormy days at Atal Setu, Bandra Sealink and the new Cable Bridge on the Connecting Link of the Mumbai Pune Expressway

Mahindra owns wind tunnels and does testing for all vehicle designs. Not sure about others.

That is utter nonsense. I am not a fan of Mahindra or Tata, but wind tunnel is standard in designing nowadays.

For Indian brands, Most of the budget is spent on Marketing and branding.. who needs wind tunnel for R&D, when all we need is Triple screen and flashy gimmicks.

The only time cars in India would worry about aero dynamics and turbulence is when it is windy.
