JLR+Ford Merger History
Lets get one thing straight, this 3.0-liter V6 Diesel is nothing new, it has a history that stretches all the way back to when Ford owned JLR. Currently, you can find this engine in the Range Rover HSE making 254 horsepower and 440 lb.ft of torque.
Caught earlier testing on Michigan roads, this emissions certificate on the prototype truck indicates it will be a 3.0L unit, rather than the 3.2 that’s offered in the Transit. The JFC1-3.0-966 on the sticker is the emissions calibration code. The JFC1 is the control unit catchword, ironically the same catchword used in the ’04 Taurus with a 3.0L. The 3.0 is the engine displacement, and the 966 is the last three digits of the vehicle tag number.
This further confirms that Ford will use the Lion V6 found in Jaguar Land Rover (JLR) products, such as the Range Rover. The engine was developed while Ford still owned JLR.
The F-150 Diesel is also identified by the diesel venturi exhaust tip. An earlier video confirmed that it sounded notably more diesel-like when running than the EcoBoost V6s that are already offered on the truck.

3.0L Lion V-6 Diesel Specifications
Although this years Detroit show was our first official look at the all-new F150 Diesel, Ford is still tight-lipped about anything to do with it. However, going off of what we know from the above point, speculation and the one fact that we'll get a 10-speed automatic, you can begin to connect the dots. DieselHub put together a short list of specifications:
3.0L Lion V-6 Diesel Specifications
- Configuration: 60° V-6
- Displacement: 183 cid, 3.0 liters
- Engine Block Material: Compacted graphite iron (CGI)
- Cyl Head Material: Aluminum alloy
- Cylinder Bore: 3.31 in (84.0 mm)
- Cylinder Stroke: 3.54 in (90.0 mm)
- Injection: 29,000 psi high pressure common rail, Piezoelectric injectors
- Aspiration: Variable geometry turbocharger (VGT), air-to-air intercooler
- Valvetrain: DOHC, 4v per cylinder
- Horsepower: 254 hp @ 3,500 rpm
- Torque: 443 lb-ft @ 1,750 rpm
- Fuel Economy**: 22 city, 28 hwy mpg
The Lion's 60 degree "V" configuration results in a narrower engine than that of a typical 90 degree, thus reducing overall engine width and possibly broadening the engine's application range. Range Rover models equipped with the 3.0L diesel employ a ZF 8 speed automatic transmission; it's difficult to speculate what Ford has in mind for the F-150, but it is bringing a 10 speed automatic to market. Whether or not this transmission can be adapted to the Lion V-6 is difficult to assess with what little is known about the future diesel option. If Ford sticks with a 6 speed automatic, the current standard for all F-150 models, they're unlikely to meet fuel efficiency targets. For the a diesel equipped F-150 to truly hit a home run, it will need to edge Ram's EcoDiesel powered 1500 model.

EPA-Estimated MPG?
On Ford's radar is what the competition gets, primarily the RAM 1500 Diesel. From all the information we have on the "Lion" 3.0-liter V6 Diesel the numbers come down to around 22mpg city, 28mpg highway and 25 combined. Unlike the RAM, Ford will be using a 10-Speed Automatic. Tough to say what influence that transmission will have on the Lion but anything that tops the Range Rover HSE will keep Ford ahead of the competition.

______________________________Improvements are of course made to the Range Rover’s fuel efficiency and overall driving range. Compared to the gasoline V-6, the diesel offers a 32-percent improvement to fuel efficiency, bringing the estimated mpg numbers to 22 city, 28 highway, and 25 combined mpg. Total driving distance for one tank of fuel is extended to a bladder-busting 658 miles.

Key Features
As you know this is no overnight success, development stretching since Ford owned JLR, and naturally from all that time and millions you can set your expectations high enough. Yes, Ford will be getting a version of this and not everything its Range Rover uncle runs but a good portion of what it has could very well stand.
While Land Rover engineers promise the Td6 been completely reworked, the architecture’s basically been around forever. It started life as a Ford engine, has been in a bunch of Land Rover vehicles since Ford’s ownership of the company, and has now been brought up to America’s tough emissions standards in its latest round of updates.
You won’t sweat where it came from once you drive it though, the engine’s full 440 lb-ft of torque comes on at just 1,750 RPM and yeah you’ll feel it in your ass alright. Horsepower is rated at a respectable 254 horsepower.
Where you won’t feel it everywhere else. Land Rover’s added more padding to the firewall and acoustic laminated glass to diesel models to subdue the “diesel experience” your mom might remember (smelly and clunky) but even standing outside with the hood open, you can barely hear this baby clatter.
If you want your diesel to sound like a bag of bearings in a dryer, you might want to keep your Cummins. But you’re probably not in the market for a Range Rover anyway.
The Td6 relies on a lot of variability to maximize efficiency. That’s the takeaway from things like “two-stage oil pump” and “controllable water pump.” Subsystems are designed to work as little as possible to minimize engine load.
Just like the Ram EcoDiesel and big rigs, this engine uses “diesel emissions fluid” (DEF) to help cut down on pollution. It’s a blue juice you add to a separate filler every 10,000 miles or so, available at any auto parts store or for much more money at your local Land Rover dealer.
