but look at cummins engines. case here is the most popular 1613 turbo for TATA . the engine is cummins 6bt 5.9 tc roughly having displacement of 6 L . but look what it produces a mare 126 bhp and torque of 410 NM.
so by this std, mahindra's 7.2L is way good.
1613 is the entry level engine.

Take 1623. 5.9 litres. 235 hp 800 Hm. Now compare. On top of it the 7.2l engine will be heavier too. Not a huge issue in HCVs, but why add 100 kg when you can save it?

Those types are called Tranversly mounted 4s/6s/ etc,etc..

Don't know about Subaru having a diesal or not, but at present we are having a Subaru Forester with Boxer petrol engine.

Ya dude, its one of the best TC engine we have here.

Cummins are expert's in CV engines, but still TATA's should have taken some help for development of there Passenger car engine's from TC.

I think the title of the thread is a bit misleading. This is not a Mahindra engine, it is a well known Navistar engine, so really it is Navistar unveiling the engine in India.

I agree. The title is quite misleading. Its a Navistar engine localised by Mahindra-Navistar to be precise.

DEAR DINAR,
when volvo first launched the FM series in india , there was only one option aveleble which was FM7 . later on they discotinued it . but you can still spot a FM7 -290 on our roads quite often.
now a days they are coming with those engines u r mentioning.
further i m also very shocked bylearning straigth and inline are not the same . explanation required!
Yes, I know the earlier models came with the D7 engine but was discontinued , due to the great demands of the India commercial [specifically good transport] market.
The point is small engine capacity with loads of BHP , is not the way here. these high states of tune are OK with road like in the US and Europe.

yeah ! that will be gr8 , but why do the impossible . the 540 will ride on only 2 front wheels bcoz of the weight of the engine and at rear you have to add an ballast so as to keep u r rear wheels in touch with mother earth.
Rather than that , lets do the possible. a Scorpio 2.2 L M HAWK or an old 2.6 L if you get it . will do wonders with MM540 . and thats possible!!!

7.2 L seems to be gem of a engine there.
It is true that Mahindra's JV's have not worked out too well in the past. But with Navistar, I think Mahindra has hit the nail right in the head. Indian Automobile market has matured a long way and people are looking for quality and don't mind paying for it. The Mahindra-Navistar JV looks like it will deliver just that: Great quality powerful Commercial trucks. I see this JV as a successful venture for Mahindra.

I just came across the Mahindra Navistar website today. I think they just launched it today only. It is a building up a teaser campaign for the Mahindra Navistar trucks.

Here is the link Mahindra Navistar

good link indeed ! seems to be a good truck to look at given how mahindra designs their CV s ( case here is gio, champion amd loadking series) never had a good run in this segament whatever they tried .
UV s there is nobody in india that can hold their hand , so as the tractors , single handedly controls 40% of market. but not with CVs . lets c at expo what are they up to designwise .

You can't make out much of the looks of the trucks from the teaser pics. But I do get a feeling that this time around, Mahindra has got the looks of these vehicles right.

Dude, boxer engines are called flat engines not straight. Straight is nothing but another name for an inline layout.

Some of the Navistar models uses Cummins Engines( 15 L ) so does Frieight Liner. Cummins got more than 60% market share around the world and got a vast array of engines for various uses.

Damn 31 tons!!! With that sort of gross weight these trucks will only have 6.77bhp/ton and 28.3nm/ton.

In comparison, the Tata Nano does 55bhp/ton and 80nm/ton.

They will be crawling with such low figures.
