CR Finds 2.7L EcoBoost V6 Ford F-150 Is Quicker Than 3.5L EcoBoost V6

People don’t buy pickups for speed, but it’s nice to know your truck can leave behind other trucks and even passenger cars at the traffic lights.

The folks from Consumer Reports were curious to see which of the turbocharged V6-powered 2015 Ford F-150s (the 2.7-liter and the 3.5-liter) is quicker. As a reminder, the 2.7-liter V6 produces 325hp and 375lb-ft (508Nm) of torque, while the larger 3.5-liter V6 delivers 365hp and 420lb-ft (569Nm) of torque.

At a first glance, everyone would bet on the more powerful engine, but the 0-60 acceleration tests revealed a surprise.

The 2.7-liter model proved faster every time, although not by a large margin. It covered the 0 to 60 mph (96 km/h) sprint in 7.0 seconds, while the 3.5-liter model did it in 7.2 seconds.

Unfortunately the video doesn’t explain why this happens, but it surely hasn’t got anything to do with magic.

    GVM? Gearing? Could be anything.

      Exactly! Or….their advertised ponies didn’t show up to play on the tested examples. 0.2 of a second is really not noteworthy in and of itself in an unloaded truck. If you were out cruisin’ the ave’s for stoplight showdowns your own driving techniques and reaction times could negate that advantage. The other detail might be fuel consumption while performing at their most. Under an owner’s typical use and loads it would be interesting to see if the smaller engine holds an advantage. A number of variables here.

    As Lotus says, lighter is better… Simple as that.

    The 2.7L’s standard rear axle ratio is 3.55, while the 3.5L’s standard gearing is 3.31. With the torque difference between the trucks, that alone could explain it, all else being equal.

    Now, the max towing package added to the 3.5L gives it a 3.55. However, if you select the payload package with the 2.7L, that gets it a 3.73.

    So, without knowing what options were checked on these trucks, we have no way to know why the 2.7L was faster. It could even have nothing to do with gearing, and more to do with the 2.7L being broken in while the 3.5L was green.

      oh wow, I didn’t know that.
      2.7 with a 3.73 sounds Sexxyy!

      My first thought was that the twin scroll turbos on the 2.7 reduced turbo lag just enough to make up the difference. The twin scroll turbo has two air paths to the compressor instead of one. This is more efficient because it allows for separation of the exhaust pulses which are coming from different cylinders at different times. In the 3.5L without the twin scroll setup, the exhaust pulses “bump” into each other reducing efficiency and turbo spin-up.

      • Kiefmo

        So, if both trucks were torque-braked and allowed to spool their turbos up, the 3.5L would probably match or beat the 2.7L. 0-60 is just one measurement of acceleration, though. I’d also like to see passing acceleration times and 0-75 (representative of interstate highways with short on-ramps).

      Standard with the 2.7 is a 3:31, while the standard with the 3.5 is a 3:15, but that’s only 2WD.

  • gregsfc

    I just purchased a 2.7 with the lower ratio/higher gearing (3.31). So I guess the 3.55 is no longer standard or is not the standard for 2WD configurations. Coming from a VW diesel to a new truck and giving up on the prospect of an affordable small diesel in a pickup, my decision criteria for choosing the 2.7 has more to do with the small price premium versus the naturally aspired, torque-in-the-stratosphere, naturally-aspired V6, the torque curve of the Ecoboost versus the competition and Ford’s standard V6, and the rated mpg, which may or may not carry over to the real world. I’ve not yet taken delivery, but hopefully, the 2.7 with the 3.31 in a Rcab, SB, 2wd will give me a good working truck, with lots of smiles with peak torque at only 3K RPM, and at least decent fuel economy, since affordable diesels ain’t going to happen for many years thanks to the EPA’s unrealistic standards on diesel NOx output.

    I have a 2015 with the 3.5 and my buddy told me about this 0-60 test the other day. After doing some more researching, according to consumer reports, the 2.7 had 3.55 gears while the 3.5 had 3.31 gears for this test. Might explain the difference. They need to test the 3.5 with 3.55 gears then see what happens.
