Ford Introduces an all-new 3.5 EcoBoost and a new 10-speed transmission

Personally, I'm not so sure the Transit needs an engine that scoots along faster than the one it has now. Granted, it would be tuned differently from the F-150, but it would certainly have more giddy up.

In other words, I certainly won't be looking to trade up in a few years because I yearn for better performance.

In the F-150 however, I'd take the more HP and torque all day long. My personal vehicle is an '04 F-150 with the 5.4. It's absolutely awesome...runs and looks like new, rides like a limo. Gets 17 MPG dead on with my road trips. I see no real reason to be rid of it in the foreseeable future.

But in the last few years I've been wondering when Ford was going to bust out the bait that I just can't refuse. A client of mine has a BMW with the start/stop thing, he says it's awesome and makes a significant difference in the gas mileage compared to the last late model Beamer he had.

I think GM needs to pull a rabbit out of the hat real quick or eat even more dust.

From the article:

The engine features an all-new, Ford-first dual-direct and port fuel-injection system. Two injectors per cylinder – one mounted in the intake port where air enters the cylinder and one positioned inside the cylinder – work together to improve power output, efficiency, and emissions.
Solution found to the carbon build up issue, as so many expected. Just use both direct injection and traditional port injection. Problem solved.

Too bad they're 8 years late to the party.

I agree more power in the transit seems overkill but some people like more power no matter what. As it is if theres anything on the floor and I step on the gas it goes slamming against the back door. However to address the BMW stop & go. two things, 1 its not as fun as you would think there is a slight pause when you let go of the brake or turn the wheel slight hesitation for power to come on. 2 theres an Eco normal sport and sport plus dynamics button and eco is like driving a prius, the opposite of fun, normal is fine like driving a typical luxury car, sport is a different animal though. Everything from throttle mapping to braking to steering effort to shock settings become more engaged, it changes the car completely and once you're in sport you never want to go back to normal and eco is reserved for people into S&M. the stop & go is deactivated once in sport, it only works in regular and eco. oh and sport plus, as far as I can tell theres no need save for launch control, you must be in sport plus for launch control to engage.

Apparently, outside of the Raptor, this combo still mostly makes the same HP as the current 3.5 Ecoboost, with a 30 lb. torque boost. From what I'm reading, the focus was on significant gains in fuel economy, smoother shifting, and beating the newer emissions regulations. I'm guessing that's why it has start/stop standard.

Nice drivetrain!! A guy could wait his whole life for new features to come out on these vans. I'll be briefly jealous when the transit comes out with this powertrain and I'm in my lowly 6speed. Haha

I'd like to see more details on both the engine and transmission.

The first question I have is what material is the block? They stated all-new and with same bore spacing and deck height as previous block, but supposedly its design was based on what they learned from 2.7 EB. Hopefully that means a compacted graphite iron block like on most Ford truck engines, but there is no mention of this. They mention heads are aluminum, which seems weird unless block wasn't.

As to transmission, one site said first gear was 4.7 to 1. Another site said total gear spread was 7.4 to 1. I certainly hope that's right.

Transmissions like the ZF 9-speed for front wheel drive have such a wide spread that some gears essentially go unused. So what's the point of having them?

If above reported ratios are close to correct, this new 10R80 seems to have a great balance between total gear spread and close ratios.

I'd sure hope the 10-speed shifts a lot smoother than the 6. Mine isn't *rough*, but I sure do notice the shifts. Adding four more shift points (pushing them all closer together) would get annoying.

As it is I wonder why 1st gear is even there on the 6-speed. I guess if I was at max weight limit it'd be useful but my van spends about 1.5 seconds in 1st then shifts. I've played with manual mode, starting in 2nd, takes off just fine there.

But then I'm probably a bit biased now. Drove my NV200 work van for over a year before getting the Transit. I *LOVE* the smooth, shift-free feeling of the CVT transmission! :) Wish they were strong enough to be used in something bigger/heavier...

RandomJoe, while automotive journalists constantly rail on all the things they dislike about CVTs, I'm with you I absolutely love them. I love knowing it has extremely large amounts of "gear ratios" to make sure my engine and transmission are running at optimum efficiency and smoothness. I love not feeling shift points!

They use more gears to allow lower gear differential and to keep the engine in the peak torque range.

More torque makes driveability better. If you've driven a diesel VW you can really appreciate the torque compared to a weak gas car.

More torque keeps the revs down as well and thus wear and economy gets better.

I'm assuming this newer design just led to more torque and wasn't necessarily planned. The design fixes any issues (probably not real) with deposits on the intake side of the valves due to direct injection.

Ecoboost is amazing and probably one of the greatest engines ever made.

Genuinely curious why you think the problem with build up may not be real.

Thanks for posting -- interesting information confirmed.

So the total transmission range is indeed 7.4:1. And first is 4.7:1. Top overdrive is about 0.64:1.

Talking about close ratios. Six underdrive gears, direct, plus three overdrive gears. So in order to get to 0.64 in three overdrive gear steps, they have to average around 0.86:1 each. On average each 2,000 RPM downshift at the high end would only go to about 2,300 RPM. That's insanely tight gearing.

This tight gearing should help a lot with naturally aspirated engines when it finally filters down to standard V6s.

I think it is funny how orton compares the Transit transmission to a Porsche Boxter. I like the tactile connected feel of a manual. But that's not the point of my Transit. Not really comparable in any meaningful way with a 2 seater little sport coup. At least for me, the debate was between the Transit and a Sprinter, maybe I'm the weird one...

A sport model with short wheelbase, low roof, ecoboost, and manual transmission would be fun. I currently daily drive my transit and have been considering purchasing a car to make the drive a little more enjoyable. If a manual transit was available, I believe that would eliminate my need for an additional car.

Did not compare the Porsche automatic transmission to the Transit automatic. Two different animals designed for a different purpose. I just prefer a manual transmission. I was comparing the Porsche with an automatic to a Porsche with a manual transmission.

I have compared the old 5 speed NAG1 Sprinter transmission to the 6 speed Transit. The Transit transmission is far superior. Have read that the newer Sprinter 7 speed transmission with the 4 cylinder works much better than the old 5-speed still being sold with the Sprinter V6.
