it still is a mystery.

I like xuv500 its awesome to drive and look great,

 

[Gurrala74]

@SB

Okay I will try to make it clear again

Body roll :

XUV is better on good roads and has less body roll than Storme(the difference is very less)

Ride quality :

XUV is more bumpy on bad roads and Storme is better

We are running in circles for no apparent reason .

Gurralla - how a vehicles behaves on bad roads is about its ride quality . Storme has a superior ride quality then xuv .

The question asked here is about " body roll " and not ride quality .

How a car behaves in corners , is it planted or it rolls and makes you nervous with its roll ? Again its not in which seats you sit , its about the entire body of the vehicle .
Have you driven the xuv and storme on good exactly same speeds around corners to tell exactly which rolls more ? Or how much is the difference ?

@ Sam
The storme compared to previous safari and other BOL SUVs rolls lesser . Compared to xuv it rolls more .
Still drive both and share your findings with us .( I assume you have already driven both the cars )

 

[Gurrala74]

Okay Raja, I confess for the confusion created

"XUV has lesser body roll compared to Storme"

Of course a monocoque will roll lesser than a body on chassis frame, both theoretically and practically ;)!!

Why?

A monocoque is a 3 dimensional design. This means it has better resistance to longitudinal forces of acceleration and braking as well as lateral force necessitated by cornering. In a body on chassis design, vertical cross members are welded with longitudinal members which essentially make the entire structure a 2 dimensional design where the longitudinal members deal with the longitudinal forces (of acceleration and braking) and the vertical cross members (at least try to) deal with lateral cornering forces. Since its a 2 dimensional structure, its torsional rigidity is extremely lower as compared to that of a monocoque (3 dimensional structure) due to which it is unable to deal with vertical loads (= ride quality when you cross a pothole) and lateral forces (= cornering) as well as a monocoque structure could. Of course there are several other factors affecting things like ride quality and body roll (a body on chassis design like the Storme could have better compression and decompression settings on its suspension to enable better control over vertical forces over a monocoque vehicle that is with stiffer suspension settings) but they cannot negate this basic structural physics.


Thanks for your inputs.

Fantastic explanation Sam..

One question: Have you driven an Innova? If yes, then how will you compare it's body roll with XUV five double 'OH'??

 

[Sam Dinkar]

@TSIVipul: OH I wish I could reply to your query but poor me has not sat ever in a Double OH. Have sat in an Innova but that was on an arrow straight highway to Nasik. Hated its NVH, though.

Maybe you could direct the same query to Iron Rock and Gurrala 74 and take their views on the same. Gurrala74, especially should be able to help you with his maturity and experience.

@Sam

Thank you for the trust on my words buddy, but to be very frank I traveled very less in Innova so far so not able to comment as even my travel was same like you on a highway and most of the time I was sleeping

No doubt on that. Most Toyota cars are a sureshot cure for insomnia.

By the way, being a Mechanical Engineer, could you please throw some light on your opinion on Monocoque vs Ladder frame design? I am more interested in knowing if a vehicle like the Storme could be made to behave like the XUV in the corners without diluting its ride quality?


p.s.: @Iron Rock: Just when we need your inputs, you body roll your way out of the forum.

Innova has a lower C.G. when compared to the XUV and Storme. The XUV's roll is similar to the Innova's. But the Innova has an overall superior ride and handling combination.

What spoils is the party in the Innova is :
1) Underpowered engine.
2) The lack of power is compensated by short gearing, which is okay in town, but on the highways, it runs out of breath.
3) Lack of proper insulation, engine noise is prominent and NVH in general is poor.

Coming to the monocoque v/s LOF discussion, it is very difficult for a tall SUV with a higher C.G. on a LOF chassis like the Storme to have similar body roll like the XUV which has lower C.G. and a monocoque chassis. To do that, TATA will have to reduce it's ride height considerably and make the suspension stiffer, in other words make it a crossover like the XUV and Aria.

Sir, why speak when you can observe and learn from the masters. Hence I do intend to body roll in a few temples and ask the divine almighty - more automotive knowledge please!

Ha ha.that wont help because the human body itself is a body on ladder design (muscles and skin bolted on to the skeleton ha!).

Master Gurrala74.enlightenment please.

 

[TSIVipul]

Rest there is no such hard and fast rule that ladder frame built SUV will always roll more than monocoque. So neither theory nor practicality support the fact that monocoque 'always' rolls lesser than BOF.
Let's get back to Storme Vs XUV...it's still XUV for me. It runs like a wild cat.
