Unofficial Details Leak About Ford and GM Next-Generation Pickup Truck Engines

Next-generation full-size pickup trucks from Ford and General Motors will have to balance towing and hauling capability with unprecedented frugality to meet tough new government fuel-economy standards. Here’s the latest information from our insider sources about the engines that will help them accomplish this feat.

Ford is said to be working on two all-new six-cylinder engines under a program codenamed “Nano.” The Nano mills are expected to continue Ford’s efforts to shrink engine displacement while using turbocharging to boost power levels and return superior mileage. They are said to have displacements of approximately 2.6 or 2.7 liters and 3.0 liters and are expected to find their way into the next-gen Mustang as well as the F-150. Other Ford vehicles are likely to host these engines, as well. The 3.0-liter V-6 is said to have a power target of approximately 300 to 315 horsepower, almost the same as today’s entry-level naturally aspirated 305-hp, 3.7-liter V-6. Instead of twin turbos, the Nano engines are expected to use so-called dual-stage turbocharging, where two different-sized turbos work independently or in tandem. One turbo is used at low speeds for drivability and fuel economy, while the second turbo spools up at high speeds to deliver extra power.

GM is expected to offer four significantly updated or new gasoline engines for the 2014 Chevrolet Silverado and GMC Sierra, in addition to the workhorse 6.6-liter Duramax diesel V-8. All of the new gas engines will feature direct injection. Heavy-duty trucks are said to receive an exclusive 6.2-liter V-8. Currently, a 6.2-liter V-8 is only available for the 2007-12 Silverado and Sierra 1500 half-tons. Light- and heavy-duty models would share a 6.0-liter V-8 that’s currently only available for 2007-2012 Silverado and Sierra HD pickups. In early planning for both large displacement V-8s, supercharging was considered as an option (similar to the 2009 Chevrolet Silverado ZR2 concept truck) for maximum power while maintaining fuel efficiency. However, supercharging has been dropped from consideration for now. GM’s next-gen half-tons are also expected to continue offering a V-8 with 5.3 liters of displacement and a turbocharged six-cylinder engine that can compete head-to-head with Ford’s 3.5-liter EcoBoost V-6. Six-speed transmissions are expected to be the standard gearbox for all engines.

I read about the Audi diesel too http://www.caranddriver.com/reviews/car/11q3/2012_audi_a6_avant_tdi_diesel-first_drive_review and I wanted it for the Tundra or Ram.

@ Curtis - the common comment among guys with turbo motors is that they burn as much fuel as their larger brethren under heavy load. That makes sense as a V6 turbo can do the work of a larger V8 by "forcing in" the same amount of air that a V8 draws in "normally". To do the same amount of work requires the same amount of energy.
The savings come in weight and under a light load.
A V8 still draws in air and fuel based on its displacement. A V6 can behave like a V6 when the turbo boost is small.

I have a hard time visualizing a small V6 turbo in a HD. It all would depend on how robust the engine is constructed. A V6 would have to been into the boost much more in a heavy HD pickup.

I find it interesting that GM seems to going the opposite direction of Ford. Larger displacement engines and maybe, just maybe a turbo V6.

The pussification of America marches on...

Jesus guys ALL of the diesels in the HD's have had turbo's for at least 17 years and no one is pissing and moaning about those turbo's are they?!

Come on the tech is well proven, the only things that might need to be beefed up at all would be the crank, liners pistons, etc.

The turbo's should be good for a hell of a long time.

We would not have to be talking about smaller engines and trucks if the Liberal Tree hugers and Obama was not forcing it on everyone.

Ford boys can laugh it off all the want, the 2014 Silverado and Sierra are going to be kick ass trucks!

The V6 turbo will most likely be the new 3.0 twin turbo that GM will be releasing within the next couple of years...5.3 V8 as the standard engine sounds nice to me.

@Jake - rumors say it will be variant of what is in the Cadillac.
Will it come with the Aisin six-speed that is found in the Caddy???
The new 5.3 will only share displacement numbers with the current 5.3. They are talking about "all new".
Time will tell. "ALL NEW" is the most abused phrase in the auto industry.
Green Motor Corporation may have a few surprises lurking up its sleeves.
A 4 mode hybrid sounds interesting. What are the other 2 modes?
Pushing or pulling?
All sources point to 2014 MY.
Maybe the fiscal crisis will be over by then.

The goal is not to build the most high tech engine. The goal is to replace an normally aspirated engine with a smaller (cost effective) turbo engine.


A 380HP 3.0 turbo engine would not be able to tow, unless Ford used some very expensive componants. No one wants to pay the extra $3000 it would take to get there when the Ecoboost 3.5 can give you almost the same power with higher reliability at a lower cost.

That said the 310HP out of a 3.0 without charging a premium and achieving even better fuel economy than the 3.7 liter V6 would make for an interesting F150. Think 24-25 MPG, with a 4x4 in an 7600lb tow configuration and you'll see where there could be going. That's about the same performance as a 2009 F150 with a 5.4 and 3:55 ring gears.

Remember Ford was tinkering around with the concept of a ecoboost 2.0 liter 4cyl in the F150. Luckily they decided it was too weak of an engine to be worth the effort. The 2.6-2.7 liter turbo V6 is probably the result of that experiment. There are also rumors that Lincoln wants access to the Nano engines.

Allistar Evans, the only F-150 that ever weighed under 4500lbs that I know of was the reg cab step side 4X2, base truck from the 91 model yr., but just under at 4479, I had one, nice truck too.

With the new CAFE standard released how much longer until we get a small displacement fuel efficient diesel into a half ton pickup? Give us one with 250/275hp and 400/500tq and with the latest in 6,7, or 8 gear slush boxes coming out should be able to get 30mpg easily with the latest advances using DEF. This isn't rocket science and even though it will not be as big as the 6 and 7 liter monsters in the HD/SD pickups it should be good to tow around 8k which should cover about 90% of the half ton owners out there.

And may I add no need to get aerodynamic or uni-body and remove the body on frame that trucks are built on now. We want trucks not cars with beds on them.

Re: Allistar Evans

Your dad will also survive an off set head on where you will not.

The 1/2 ton trucks have become so capable in their towing and power ratings that there is no going back to lower power levels, lighter, smaller trucks in an effort to meet these insane CAFE standards; it would be simply unacceptable to the consumer.

It is physics and thermodynamics which says that if you want to pull a 28' RV trailer loaded down with gear and your family, that you need X amount of energy to pull it and Y amount of mass in your vehicle to control it and stop it and 2 full rows of seating to carry everyone.

There is room for efficiency in the engines and driveline and in Aero. A smaller boosted engine is more efficient than a big V8 in 80% of everyday conditions when there is no need for maximum power output.

I would expect the next F150 to be vastly more aerodynamic, a little bit lighter, possibly 2-4 inches narrower with bowed out door interior like the new Explorer. The 8-spd autos will allow crazy tall axle gearing, as you'll have 6 gears before o/d, compared with 3 or 4 now.

General Motors is going to significantly reduce the weight of all it's trucks, and eventually all of it vehicles. G.M. has somewhat recently taken an active interest in carbon fiber, and it's structural application. It has announced very recently that it is now able to mold carbon fiber in a matter of minutes not hours. This is a huge breakthrough for obvs reasons.

I have a friend who owns 2F150 ecosystem 14mpg my daughter has a F150 16 mpg my friend also has 1 F250 5.4 15mpg I have 2500 hd 6litre 15mpg Seirra a little confused about this great mileage from ecoboost no one that's honest seems to be getting it why

It is highly likely that the 3.5 liter inline 5 cyl turbo diesel is going to make its US debut in the T series vans. If the sales are large enough you might see it in an F150 at some point in the future.

That would be a 26mpg+(when unloaded) F150 with 240HP and 360lb of torque.

FYI... It will probably cost more than the Eco-boost 3.5
