Ford updates Power Stroke diesel V8, strengthens F-450, tweaks King Ranch

Ford is giving its F-Series Super Duty trucks some upgrades for 2015, and we're happy to say that one of them is an improved Power Stroke diesel V8. Also, Ford is strengthening the top-of-the-line F-450 to handle more abuse. And if wild west-style luxury is your thing, the automaker has performed minor cosmetic updates to its King Ranch Edition trucks, as well.
The turbocharged 6.7-liter Power Stroke V8 is currently rated at 400 horsepower and 800 pound-feet of torque, and Ford only tells us the new and improved Power Stroke can "produce power beyond today's" engine. What, then, did Ford actually improve upon? First, the Blue Oval swapped in a new, larger turbocharger. The new Garrett GT37 turbine unit is 72.5 millimeters in diameter, eclipsing the old GT32's 64-mm diameter piece. Ford states output increases with the new turbo setup, but since the new turbocharger operates at a lower peak pressure than the old one, the automaker was able to eliminate the wastegate system and reduce the engine's complexity. Ford even redesigned the turbo's oil and cooling lines to make the powerplant simpler. A byproduct of the larger turbo is better engine exhaust braking, which is controlled manually by a button on the dashboard.
Ford claims the upgraded diesel engine is more powerful, more robust, more efficient and more refined than before.

Ford won't be releasing GT500 lap times for the 'Ring, or any other car

Trucks have towing capacity, EVs have driving range and performance cars have Nürburgring lap times. What do all three have in common? They should all be taken with a grain of salt. Currently, there is no sanctioned way to record lap times or verify production-spec cars - a lesson we recently learned with the 2015 Nissan GT-R Nismo - and until there is a way to do so (and there probably never will be), we'll never officially know the actual time it took for Ford to lap the 'Ring with its ultra-powerful Shelby GT500.
After posting a Ford-made video of a 2013 GT500 running around the 'Ring, the guys over at SVTPerformance.com (an enthusiasts forum not affiliated with Ford or SVT) wanted more answers. They got in touch with Ford's Global Performance Vehicle Chief Engineer Jamal Hameedi, who said until there is a way to verify the times and inspect the cars, Ford will not get involved with lap-time wars. In the email, Hameedi pointed out that the 'Ring is a useful tool in that it allows a wide spectrum of track conditions, but until there is a governed way to record times, there is no way to accurately compare cars head-to-head.
And as much as some may not like it, Hameedi speaks the truth. It really isn't possible to compare times from one car to another, unless those cars were lapping the same track at the same time with the same driver. Not that any of this means there won't be continuous wars by fans and manufacturers alike... in other words, feel free to voice your opinions in the Comments below.

2018 Ford Expedition vs other big SUVs: How it compares on paper

With our Alex Kierstein rightly impressed in his first-drive review of the new 2018 Ford Expedition, we decided to dig a little deeper into the numbers, and we came up with the spreadsheet below to highlight how the new 2018 Expedition compares on paper to its main full-size SUV competitors: the 2018 Chevy Tahoe and Suburban (and therefore the 2018 GMC Yukon), 2018 Toyota Sequoia and 2018 Nissan Armada. We also threw in the new, even bigger 2018 Chevrolet Traverse since, as you'll see, its massive dimensions should put it on the radar for anyone who needs loads of passenger and cargo space but doesn't care as much about towing. A few notes about the chart above. First, the 6.2-liter V8 that's included with the new-for-2018 Tahoe RST trim level is the standard engine on the GMC Yukon Denali. You can apply most of the Tahoe's numbers to the entire Yukon and Yukon XL lineup. Second, though we highlighted categories where the Traverse led, we also highlighted the runner-up full-size SUV, since this was ultimately about that segment. Traverse numbers are broadly applicable to the new Buick Enclave.
