Cummins to have new 12-litre I6 by 2018?

According to truckinginfo.com Cummins Inc. is working on a new engine, the X12, that will be available in 2018.

The Cummins X12, notes truckinginfo.com, aims to redefine the medium-bore, 10-litre to 13-litre engine category by setting new standards for productivity in regional-haul, vocational, and intermodal truck applications.
At least 150 lb lighter than the next closest competitive engine and up to 600 lb lighter than other medium-bore engines, the new 12-litre will still deliver between 350 bhp to 475 bhp and 1250 to 1700 lbft of peak torque.
It is expected the new X12 engine will weigh 2,050 lb, it has the highest power-to-weight ratio of any heavy-duty engine between 10-litre to 16-litre in size. News of Ummins' new engine comes hard on the heels of International launching its 'new' 12.4-litre A26 which is in the same horsepower and torque range of the X12.
The big question is: Will this engine have a compacted graphite iron (CGI) block when it is introduced?
It is understood that at least one company is planning to offer the engine to its customers in 2018 and beyond.
Alkane Truck Company, a South Carolina-based assembler of alternative-fuel vehicles, is said t0 be exploring a supply agreement with Cummins in a bid to offer clean diesel engine options for Alkane’s line of heavy-duty trucks and off-road vehicles.
Pending successful engineering tests and modifications, truckinginfo.com notes that Alkane has identified three Cummins engines to offer its customers. These are the V5.0 engine for the Alkane Dominator, the B6.7 diesel engine for the Class 7, and, once it becomes available in 2018, the X12 engine for the Alkane Class 8 heavy-duty trucks.
This supply agreement would accelerate the company's operations and vision of introducing clean diesel engines to join the broad range of alternative fuel vehicles for the trucking and off-road vehicle industries in America.

Because the coming Cummins X12 is 249 lbs less than Navistars A 26 with CGI in the block I am claiming that Cummins has a CGI-block too.

You can´t make such an achievement without changing the block material.

Cummins 5 l V8 has already a CGI-block so the Cummins folks is well aware of the advantages for CGI.

Let's not get too excited about this 'new' Cummins engine. The company already has an 11.9 litre, dubbed the ISX12. Simplifying the nomenclature to X12 follows that undertaken with the ISX15, which after some useful but not fundamental upgrades, has become the X15. The ISX12, when first launched, was shipped in from a Cummins joint-venture plant in China, but it is now being produced in the US, with Kenworth tipped as the first OEM to offer it.
Its transformation from ISX12 to X12, with accompanying important weight savings and marketing hype, almost exactly parallels Navistar's 12.4 litre transition from N13 to A26.
