Not really, with an IFS equipped SUV, these coastal roads can be tamed, like I do with GV. C'mon, you have seen NH-17 in monsoon. I recall you taking a diversion to avoid it.

Sharath,

I wasn't in my JEEP.

To what average speed can a modern SUV tame "NH17" type roads? Bomb Craters & Great Divides.

Rough and Rutted roads, IFS has definite advantage.

In such cases the IFS makes the ride more comfortable and marginally faster.

And then again we know what a GV can do off-road.

Regards,

Arka

PS - Follow up on the "BOWLER WILDCAT" suspension

Guys,
With cruise-ability i meant on road where one could go fast as other cars but couldn't because of limited engine power and short gearing.
IFS is good for bad roads, no doubt one can be faster on it without being too uncomfortable. Again lot of factors here, depends on the vehicle and the type of surface generally traveled on.

Agreed Vinu My Friend - But Solid Axle Coil Springs will be better than Leaf Springs right?

Hi Spike,

Even I got some pics and parts list of the NEF TCI 2.49L only problem is its a 13mb PDF File.

But let me give you my inferences.

The 2498cc XD3P engine has the best power to weight in its class (2.5L or under 200kgs Diesel) 76Bhp/194Kgs up to 128Bhp/210Kgs for the XD3TI (TCIC)

Also the Peugeots XD3P is designed to rev up to 4600rpm, phenomenal for a 4 Cyl Diesel Engine.

So what does M&M Do in the NEF.

i) Changes the Bore X Stroke of its Pet Engine; the B275 Family Engine Block to 2498cc.

The question is why didn't they stick to 2523cc of the MDI3200TC or the 2650cc of the SZ2600, It is because of the Crankshaft/Con Rod/Piston and Rotating assy design, of the Peugeot XD3P is far superior.

ii) Change it to wet-liner like the XDP4.9/B275 (e.g NEF TCI 2.49L).

iii) Retain the Push-Rods and the XD3P Crank-Shaft.

You get a 2498cc engine which revs up to 4600 RPM (when required/allowed)

So what you get, best of both world, Reliability and RPM.

Torque & BHP go hand in hand and that depends on the Fuel Injection System and now you have CRDI.

SPIKE 2 Direct Questions to you.

1) What is the displacement of the NEF Crdi?

2) What is the Weight of the NEF Crdi?

Regards,

Arka

PS - wrt the pics it looks similar to a MDI3200TC or SZ2600 block

Welcome To Ganesh Auto Industries

Guess which one?

Then again the THAR has Leaf Springs at the back, how-come this does not affect cruising ability?

Trucks have Leaf Springs, even the Dakar Rally winning KAMAZ have Solid Axle Leaf-Springs.

Lot faster than Jeep, or any car or bus or lorry... Even normal SUV drivers are wary of driving fast on bomb craters because they are not sure. But I rip though these roads and don't have issues.

IFS is good not just for good roads, but for really screwed up roads. My OE HT tyres were worn out and had to be replaced at 17,000 kms.

Hi Arka, i like your agreement but, if you refer the above link you will find that there is an Ashok Leyland engine with 2498 cc and 94.0 mm bore, what do you say about that? is it from ford, peugeot or M&M?. 1. Crankshaft, conrods and pistons cannot be same as the power and torque generated by NEF engines is much much higher than XD3P engines,they may look similar but the weight grading, cross sections and materials are different. 2. NEF CRDi 2.6L displaces 2609cc and NEF CRDi 2.49L displaces 2498cc.
3. Weight of engine is 187 kgs with all fluids topped up. Hope it is clear now.

Spike

P.S. Arka please decide first, which engine does NEF resemble to XD3P,SZ2600 or MDI3200 (SZ2600 is a square engine, MDI3200 is undersquare and XD3P is oversquare), you cannot stand on three boats at the same time, and if you say NEF resembles SZ2600/MDI3200 that means your logic of NEF resembling XD3P is incorrect. Let me know the answer once you decide on this.

This might be a little off topic over here but as per my discussion with the local M&M Service guy while discussion Bolero CRDe engine and M-Eagle, he said that even though from outside they may look same, they are different engines with difference being in the Cavity in the Piston Head and slight modifications in the head. Apart from this the ECU tuning is also different. Atleast M&M accepts that the Bolero CRDe is based on the XD3P and is not NEF.

New twist to the tale !!!
You have confused between engines. Bolero CRde engine is also M eagle and belongs to NE family

M&M has been denying Bolero CRde has anything to do with XD3p. 2498cc is the bone of contention

NO! M&M says that the Bolero CRDe is not M-Eagle but is an old gen engine based on the XD3P. It has also said this to automags Mahindra Bolero CRDe - Jaunty Roads

DB Sir/ Spike Arrestor Sir please explain
