2015 Ford Super Duty PowerStroke Diesel Output, Tow Ratings Revealed: 440 hp, 860 lb-ft, 31,200 Pounds


2015 Ford F-250 Super Duty King Ranch Crew Cab

Ford is the one throwing down the gauntlet in the heavy-duty truck wars this time, having just announced another power infusion for its F-250, F-350, and F-450 Super Duty pickups. Ford promised that it would give its 6.7-liter PowerStroke diesel V-8 more power when it gave us a preview of the new 2015 Super Duty trucks last fall, but now we have the numbers to back up the claims: 440 horsepower and 860 lb-ft of torque, up from 400 horses and 800 lb-ft on the 2014 models.

That’s considerably more grunt than the 397 horsepower and 765 lb-ft of torque of the 6.6-liter Duramax diesel V-8 that powers the 2015 Chevy Silverado HD and GMC Sierra HD. It also out-torques (barely) the Ram Heavy Duty’s 6.7-liter Cummins inline-six diesel engine, with its 385 horsepower and 850 lb-ft of torque. See how this works?

Payload and towing capacities rise in turn, with the max tow capacity of the F-450 rising from 24,700 pounds to 31,200, should you have a naval ship anchor in your back yard that needs to be hauled away. This bests the Ram by 1200 pounds and the GM twins by 8000, or roughly the weight of a full-grown white rhino. The F-350’s towing numbers rise as well, with maximum fifth-wheel/gooseneck trailer towing rising to an utterly ridiculous 26,500 pounds.

Furthermore, Ford claims that the design of the engine made it relatively easy to upgrade, and that the newfound power does not come at the expense of efficiency. “The designers of the original 6.7-liter PowerStroke V-8 turbo-diesel predicted that it would eventually need to be upgraded for higher output,” said David Ives, Ford Power Stroke technical specialist. “They designed it in a way that made it easier to add a larger turbocharger, increasing airflow and creating more power for dramatically improved performance, yet we haven’t lost any efficiency.”

In its chest-pounding press release, Ford says “The improvements we’ve made essentially give Super Duty customers an engine designed for our larger F-650 and F-750 trucks. They may not realize how tough this engine really is.”

Don’t expect Ford’s lead to last long, though. We give GM or Ram until the end of summer to re-flash their ECUs and slap on more powerful turbochargers to squeeze more twist from their diesels. Indeed, in this particular power play, no one wears the crown for long.

Refreshing or Revolting: 2016 Chevrolet Spark
Is the U.S. ready to embrace subcompact cars?Last year, Chevrolet only sold 39,000 units of the Spark here in the U.S., but the all-new 2016 Spark is hoping to change that number. The pint-sized Spark will now be sold in 40 countries around the world, and the second-gen model will be longer, lower, and more powerful than the model it replaces. While a lower roof may hinder some passengers in the rear seats, Chevrolet engineers have also lowered the passenger hip point, helping to negate this issue. Thanks to the lower stance and stiffer frame, the ride and handling should be much better than the outgoing Spark. And while the overall styling of the 2016 Chevrolet Spark has been kicked up a notch, is it enough to excite Americans who aren't that enthusiastic when it comes to subcompacts and microcars? (View Original Story on Moter Trend)

Mixed Crash Test Results For Two Best Selling 2015 Ford F-150 Pickups
The aluminum-body 2015 Ford F-150 crew cab, 4-door pickup with a full-size back seat, aced a full slate of recent crash protection evaluations, but its extended cab sibling, a shorter body version with a compact second row of seats, struggled in a key test. Those were the main findings of a report released today by the Insurance Institute for Highway Safety, a nonprofit financed by the insurance industry. In the small overlap front test, each F-150 was assessed in an evaluation that replicated what happens when the front corner of a vehicle collides with another vehicle or an object such as a tree or a utility pole. While the crew cab’s occupant compartment held up well, the extended cab’s occupant compartment collapsed, seriously compromising survival space for the driver. (View Original Story on Forbes)

IIHS says that Ford "shortchanges" some buyers by equipping certain F-150s with protective front-end structural elements and not others. Extended cab models, which don't include the protective steel bars, scored just "Marginal" in the small overlap test. (View Original Story on Moter Trend)
