Engine specs:

6 cylinder 24 valve inline
7118 cc
Direct injection turbo-charged with intercooler
210 bhp @ 2,200 rpm
880 NM of torque @ 1,400 rpm
Bore 105 mm
Stroke 137 mm

From Mahindra's press release:

Quote:
December 7, 2009, Mumbai: Dr. Pawan Goenka, President, Automotive Sector, Mahindra & Mahindra Ltd. and Mr. Dee Kapur, President, Navistar Truck Group, USA, today unveiled the world renowned, technologically advanced MaxxForce® 7.2 diesel engine in Mumbai. The introduction of this engine is the result of the partnership between M&M and Navistar, which have formed joint ventures to manufacture engines and trucks in India.

MaxxForce® 7.2 diesel engine, the most modern engine in its class, will power Mahindra Navistar’s new range of M & HCV trucks and buses which will be introduced in the Indian market in the coming months.

The MaxxForce® 7.2 engines will be manufactured at a state-of-the-art engine manufacturing plant at Chakan in Maharashtra. The plant will be spread across 23 acres of land and is equipped for serial production of medium speed diesel engines.

“The MaxxForce® 7.2 engine is known the world over as a high performance, reliable and fuel efficient engine and it is now all set to redefine the M & HCV (Medium & Heavy Commercial Vehicles) segment in India. The engine has been designed for rugged operating environments and modified substantially for Indian truck requirements which will make it the driving force behind our forthcoming range of M & HCV Trucks. Mahindra & Mahindra has always been at the forefront of technological innovation and by partnering with Navistar Inc., the world leader in diesel engine technology, we are well positioned to revolutionise the trucking business in India,” said Dr. Pawan Goenka, President Automotive Sector, Mahindra & Mahindra Ltd.

“I am delighted to introduce the MaxxForce® brand of engines, which power the world’s best trucks, to the Indian market. With its outstanding performance and low cost of ownership, I am sure that the MaxxForce® 7.2 diesel engine will enjoy the same equity in India, as it does across the globe. We are also pleased to extend our association with Mahindra which is one of India’s leading auto brands,” said Mr. Dee Kapur, President, Navistar Truck Group, USA.

In 2005, Mahindra & Mahindra Ltd. and International Truck and Engine Corporation - the operating company of Navistar - entered into a JV to manufacture light, medium and heavy commercial vehicles for India as well as export markets. The Joint venture is in the process of addressing every segment of the commercial vehicle market from 3.5 tonne GVW to 49 tonne GVW with variants of passenger transport, cargo and specialized load applications. Mahindra Navistar aims to expand its product line over the next two years to emerge as a full range commercial vehicle player.

About the MaxxForce® 7.2 diesel engine

The MaxxForce® 7.2 diesel engine is a 7.2 litre in-line six cylinder diesel engine and will bring new levels of power, reliability and fuel efficiency to on-highway heavy commercial vehicles in India. It is, in fact, the most modern engine in its class in terms of product configuration as well as components technology for the HCV segment in India. With the 4-valve per cylinder technology, the engine has been designed for better performance, higher power, better fuel efficiency and stricter adherence to emission standards.

The engine features both, a mechanical injection system with a Bosch Rotary pump, as well as a high-pressure 1800 bar common-rail fuel injection system. This ensures outstanding fuel economy, performance and durability. The MaxxForce® 7.2 diesel engine to be produced in India is also fully compliant with BS III and BS IV emissions standards.

The new MaxxForce® 7.2 is positioned to outperform the competition in three distinct areas- Performance, Reliability and Fuel Economy:

Performance

• The Engine delivers maximum power of 210 hp @ 2200 rpm. Other versions of the engine in higher and lower capacities will be launched in due course.
• With the max torque of 880 N-m at a low speed of 1200-1400 rpm, the engines provide superior lugging power with minimum gear changes, even on steep gradients.
• The turbo with charge-air cooler is tuned to reduce noise, improve fuel economy and make MaxxForce 7.2-powered vehicles responsive and driver friendly.
• The combustion technology with a 4-valve per cylinder and optimized fuel injection system helps in achieving stringent BS III emissions without any after treatment.

Reliability

• The MaxxForce® 7.2 has been extensively tested both in Brazil as well as India.
• It has also been tested on trucks in various geographic and climatic conditions across India. This has resulted in 15,000 plus hours of engine testing and 1 million kms of development and validation on Indian Roads.
• Directed piston cooling jets and gallery-cooled pistons help achieve maximum durability and reliability and assure outstanding power and engine life.

Ease of maintenance:

• The uniquely designed individual cylinder head ensures maintenance and repair cost is minimized.
• The steel cylinder head gasket is modular and has a long life, with low replacement cost and ease of service.
• The wet liner design ensures minimum replacement cost for liners
• The water pump is driven by the engine gear train instead of the belt, allowing trouble free operation. It also avoids chances of engine seizure due to belt failure.

seems like mahindra has built their own thing to take on the cummins and CATs of the world.

nice move.

probably now TATA can source their engines from Mahindra. i hope this does not have a rabbit tooth logo covering the top of the engine.

@GTO.
this might be a little difficult to fit in a 4x4 unless ofcourse its the size of a TATRA truck, or maybe an arjun tank (20x20).

anyways, introduction of Direct Injection technology in HCV is good, now we may have more people who cater to repair and servicing of these type of engines.

This is not an indegenous mahindra design, rather something along the lines of Tata Cummins engines.

Mahindras have shown interest in yachts and boats and diffrent versions of these maxx engines might power them.

yeah, can you do some magic and cram it into a Scorp? Or how about a half sized on with Half the Torque at the same rpm for Scorp.

Further to my previous post, I cannot think of a better engine for the Mahindra Axe a.k.a. Indian Hummer

I'm sure this will be for their 49 Tonner tractor trailer. I would be interested to know how many turbo's will this monster have

Isn't the engine from Navistar engines? Mahindra is just introducing it in India for the trucks they are going to manufacture. Navistar are OEM suppliers.

Pardon me, but is the Mahindra Axe being sold for general public or only for military use.

'Axe Effect' from Mahindra is awesome, so masculine and looks Good

-------------------------------------------
The AXE is not for the public. As on date it is still undergoing field trials in Rajasthan and siachien. First results are satisfactory. But with the Indian army, that's a long way to go to commissioning.

Im assuming this is a straight 6 engine.
They cannot fit a 7.2 straight six in an axe/jeep.
Plus imagine the weight distribution.

here is a link where you can find all the literature for MAXXFORCE engines.

MAXXFORCE

the best for SUV application i guess is the 4.5L V6 in the defense section.

210 bhp sounds good, but for a tractor trailer it aint that great figure to be amused at.

i hope mahindra does good this time with its venture with navistar . becaues looking back at their history of tie-ups everything have failed or disputed in some way .
look at mahindra -ford and mahindra -renault ,nothing have worked for them unless and untill they do it independently , and thats their real strength.
7.2 L seems to be gem of a engine there.

whats the need of assuming that this is a straight 6 engine? GTO has clearly mentioned in this first quote , thats its a 6 INLINE ENGINE.
