Powertrains

OK. As discussed, now we get to the powertrains section of How I Would Do It. As with the Platforms post, I do not claim to be an engineer so I cannot attest to either the technical or financial feasibility of what I am proposing. Rather, what I am proposing is a reflection of recently announced technological directions combined with what are hopefully reasonable evolutions of existing engine and transmissions that are currently offered within the Ford Motor Company vehicle lineup. As an example, Ford has recently introduced the 6 speed automatic (6a) transmission/transaxle, and that would be utilized in most applications. I also envision the introduction of an 8 speed automatic for certain luxury and performance applications. If at all possible, the engines would be of a modular family that share basic bore spacing, some block casting, mounting points, and accessory components. That being said, here are the powertrains.

4cyl - Gasoline

This would be a DOHC 16 valve aluminum block with Direct Injection (DI). This basic engine running an Atkinson cycle would form the basis for a two-mode plug-in hybrid powertrain. ecoBoost turbocharging would be present for sport/SVT/SHO applications. Typically the engine would be mounted transversely, and would be coupled with 6m and 6a transaxles, and CVTs in hybrid applications. Basic displacements would range from 1.5L to 2.5L, and basic output would range from approximately 130 hp to 240 hp in ecoBoost turbo configurations.

6cyl – Gasoline

This would be a DOHC 24 valve aluminum block with Direct Injection (DI). This basic engine running an Atkinson cycle would form the basis for a two-mode plug-in hybrid powertrain. ecoBoost turbocharging would be present for sport/SVT/SHO applications. The engine could be mounted either transversely or longitudinally, and would be coupled with 6m and 6a transaxles or transmissions, and CVTs in hybrid applications. Basic displacements would include 3.0L and 3.5L sizes, and basic output would range from approximately 250 hp to 300 hp for naturally aspirated motors, and up to approximately 340 hp in ecoBoost turbo configurations.

6cyl - Diesel

This would be a turbocharged and intercooled DOHC 24 valve direct injection engine, sharing its basic architecture with the gasoline engine. Bluetec-type emissions control methods would be employed to ensure 50 state emissions compatibility. It can be mounted transversely or longitudinally, and would be paired with 6m and 6a transmissions or transaxles. Bore and stroke allow for both 3.0L and 4.0L engines, and output would range from 235 hp to 295 hp. 6m and 6a transmissions.

8cyl - Gasoline

This would be a DOHC 32 valve engine with Direct Injection. ecoBoost turbocharging would form the basis for an SVT/SHO application. The engine would be typically mounted longitudinally, and bore and stroke allow for displacements ranging from 5.0L to 7.0L Standard output would range from 370 hp up to 450 hp, with top Mustang variants (i.e. Shelby GT500 KR, etc.) pushing out around 600 hp. 6m and 6a transmissions would be offered, with certain vehicles offering an 8 speed automatic.


8cyl - Diesel
As with the 6cyl variants, this would be a turbocharged and intercooled, DOHC direct injected engine. Bluetec-type emission control methods would be utilized for 50 state emissions compliance. The engine would typically be mounted longitudinally, and would share basic architecture with the gasoline variant. Displacements could range from 5.0L to 7.0L, with the initial engine sized at 6.4L. Output for the 6.4L ecoBoost turbocharged variant would be approximately 370 hp. Transmissions would include 6m and 6a transmissions.

I hope that provides a little more insight into where I would take the FoMoCo lineup. Full vehicle lineup posts will be coming in short order. Then you can all see how the vehicles I'm talking about utilize the platforms and powertrains that are proposed here.

Stay classy out there.
