ARIA is full time 4WD. However it has a Disconnect mode where user can manually select 4x2 mode.
There is a center diff and in normal usage torque distribution will be about 80% rear and 20% front.
This basically means that you can safely drive the Aria in 4x4 mode on normal roads.

Safari and Scorpio have no center diff, and driving on tar roads in 4x4 mode will result in damage

OK that explains the use of word AWD instead of 4X4 . Does it have a choice of lower gear ratios similar to 4L ?
Also is there any information on the Hill Assist feature ? Can you comment on GC is it same as in Safari or more / less ?

[tsk1979]

No specific mods like 4L etc., in the Aria. Think of it like a softroader with limited offroad capablity. Lets say you went snow hunting in winters, or some trail driving.

Also ARIA is a selectable 4X4 and not a full time AWD like Toyota fortuner. It may be same borg-warner electric shift which is used in Safari.

Did someone in Auto expo notice 4H,4L selection switch ?

As I have understood from Tata Executives from the stall, its all time 4x4 by default, the torque distribution increases where ever wheel is slipping. you can disconnect to 4x2 by electrical switch, if required

Guys , Looking at the specs, it seems the engine is clearly intended for a CV application what with that mammoth 470 NM coupled to relatively lesser 193 PS.
CV engines as we know are tuned more for Torque and not absolute power and also lower RPM compared to a similar capacity car engine.
Wrong comparison though but supercars like Lambo and Ferrari have models which have power in the range of 500- 550 BHP with a peak torque of just 550 NM.
So this might well be the first of the CRDI tech engines which Tatas were planning in their next gen LCVs which are under development.
Come on TATAs bring it on.......but when can we expect the 3.5 liter engines which are to be fitted on the 9 and 11 tonners....

Tucked in a corner behind one of the low floor busses was this

Attachment 261317

Attachment 261318

The spec sheet reads :

4 cylinders, 3 Liter displacement

16 valves, Turbocharged and intercooled

Max power 193ps

Max torque 470 Nm

High pressure common rail fuel system

Euro 4 emissions, upgradeable to euro V and above

After treatment system for EURO IV and beyond

Available in 2 versions - for GVW greater than 3.5 tonnes and less than 3.5 tonnes

......which means, this engine's gonna be available in the NG Safari and the ARIA in the future. The ARIA zooming ahead dramatically, posted by someone in this thread's earlier avatar might have been the one with this engine in test.

AND ITS A 6 SPEED GEARBOX

Thanks for clarifying. This makes the Aria the first Indian model with automatic all wheel drive.

However even if the vehicle can safely be driven on tarmac roads , wouldnt selecting 4x2 mode increase the fuel efficiency ? I would like the 4x4 mode on hills, rainy days and rough roads but not within the city especially if I can drag out a few extra kilometers on the same amount of fuel.

[tj123]

Engaging all wheel drive 4x4 on normal city roads will be a big drag on the engine resulting in lower FE , leading to extra wear & tear on transmission components.
4x4 mode is especially useful for off-road conditions such as rural roads, hills, rainy condition, deserts and bad roads.
2 wheel drive is more than sufficient for city usage.

Found some write up on the 4WD system with multiple clutch where normally spilt of torque 5:95 in Front:Rear axle, and it improves the torque distribution in the front as the wheel starts slipping through Multi - Clutch system which operates through electronic sensing

I guess 5:95 Torque distribution would even help in city, Imaging start up from standing condition on Signal, the Rear will get 95% torque and they will push the SUV same time front will get 5% torque which will support the movement. and so On

Multiple-clutch systems Credit to Wikipedia

• Acura RL, RDX (SH-AWD) Right and left axle shaft
• Acura MDX SH-AWD & VTM4
• Honda Ridgeline
• Honda Pilot
• Infiniti FX (ATTESA E-TS)
• Mercedes-Benz 1st generation 4MATIC (rwd normally, automatic clutch in transfer case engages 4wd on demand)
• Mitsubishi GTO MR/3000GT VR-4
• Mitsubishi Lancer Evolution Series S-AWC
• 2010 Mitsubishi Outlander GT S-AWC
• Mitsubishi Outlander (2003-2006) independent front and rear axle coupling, and Active Center Differential.
• Nissan GT-R (ATTESA E-TS)
• Nissan Skyline GT-R (ATTESA E-TS and ATTESA E-TS-PRO) front axle coupling, rear differential locking
• Nissan Skyline GTS4 (ATTESA E-TS)
• Nissan A31 Cefiro SE4 (ATTESA E-TS)
• Porsche 959 PSK front axle coupling, rear differential locking
• Saab 9-3, Saab 9-4X (Saab XWD).

Multi-plate clutch coupling
the above all function like 2WD when multi-plate clutch coupling is not engaged, and like 4WD highrange in a part time 4WD system when the clutch is engaged (usually by computer although some allow manual control). Some in this category have varying degrees of control in the torque distribution between front and rear via allowing some of the clutches in a multi- plate clutch coupling to engage and slip varying amounts. An example of a system like this is the BorgWarner i-Trac(TM) system. Note: the Haldex Traction-based car list was created from the list on Haldex Traction corporate web site: Haldex Cars. Interestingly, a version of the BorgWarner ITM3e system is used on 2006 and up Porsche 911TT's. The Borg-Warner ITM 3e is also used in the 2006-now Hyundai Santa Fe and the Hyundai Tucson. In the Hyundais, the ITM 3e acts like an full-time AWD with 95:5 normal torque split. In extreme conditions the system can be locked in a 50:50 split via the 4WD LOCK button.

Great job team-bhp. Excellent coverage of TATAs new vehicle. By any chance is TATA going to update/modify the current Safari soon!

[VINUMON]

BTW, how the name Aria is pronounced? As Arya(n) or as in Area, or...wht else?

[chaxy]

Does the ARIA have automatic ORVMs ? from the pics looks like it does.

[aditya79india]

with so much speculation going around why is sidindica missing? Why dont the mods subpoena him?
