Ford's Second-Generation 3.5-Liter EcoBoost is More Powerful Than We Thought
Ford clearly low-balled its power figures when it issued a sneak peek of the second-generation 3.5-liter EcoBoost V6 back in May.
The newly massaged engine, which will get its debut in the 2017 F-150, was thought to gain 30 pounds-feet of torque. Now, Ford claims the mill will gain 10 horsepower and 50 lb-ft, for a total of 375 hp and 470 lb-ft — a torque figure that beats the F-150’s V8-powered competition.
Ford will mate the twin-turbocharged mill to its new 10-speed automatic transmission, which was the result of a joint project with General Motors.
Engine tweaks include a dual-direct and port fuel-injection system that delivers fuel to both the intake port and cylinder, and turbochargers with lighter turbine wheels and electrically activated wastegates. The EPA hasn’t weighed in with fuel economy estimates, but Ford says buyers can expect improved acceleration and overall performance.
The new EcoBoost’s twist easily tops that of its domestic competitors. A Ram 1500 with a 5.7-liter V8 makes 395 hp and 410 lb-ft, while the 5.3-liter V8 in the Chevrolet Silverado and GMC Sierra makes 355 hp and 383 lb-ft. A move up to GM’s 6.2-liter V8 still isn’t enough beat the EcoBoost’s torque — that mill only boasts 460 lb-ft. The 6.4-liter V8 in the Ram 2500 makes 429 lb-ft.
Sales of the Ford F-Series could clothe and feed the families of a modest-sized country. The automaker has no trouble achieving massive sales figures, so an even brawnier EcoBoost will only help broaden the lineup’s appeal. However, the new mill does make the F-150’s available 5.0-liter V8 seem somewhat disposable. Come this fall, that engine will offer just 10 hp and 17 lb-ft more than its six-cylinder brother.

- Tassos And all 3 were ordered by Fisker's mother. Seriously, given Fisker's terrible record of Failure in the past, only an utter loser, (for example, VGhost or Art Vandelay?), looking for a BEV terrible enough to be a proper replacement of his 11 mile range Fiat 500E, would order one of these. (apart from Fisker's mother)
- Tassos And all 3 of them were ordered by Fisker's mother.Seriously, after Fisker's DISMAL record of UTTER FAILURE in the past, only a GOD DAMNED MORON would order this one.
- RHD Any truth to the unconfirmed rumor that the new, larger model will be called the bZ6X? We could surmise that with a generous back seat it certainly should be!
- Damon Thomas Adding to the POSITIVES... It's a pretty fun car to mod
- GregLocock Two adjacent states in Australia have different attitudes to roadworthy inspections. In NSW they are annual. In Victoria they only occur at change of ownership. As you'd expect this leads to many people in Vic keeping their old car.So if the worrywarts are correct Victoria's roads would be full of beaten up cars and so have a high accident rate compared with NSW. Oh well, the stats don't agree.https://www.lhd.com.au/lhd-insights/australian-road-death-statistics/
Long live the v8. The v8 is dead.
A Rolex is a pretty piece of jewelry with a mediocre timepiece built into it. I love mechanical watches but for accuracy you can't beat quartz. Cincinnati had the old Gruen watch company in town, and when they closed up in the 1950s, I'm told that many of their watchmakers who built their movements in Switzerland went to work for Rolex. I also read somewhere that Rolex bought Gruen's office space in Switzerland. That's your useless non-automotive trivia for today. On the subject of DI gas engines, the technology makes me nervous. There's something to be said for Toyota's habit of sticking with older technology...
