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.

Junkyard Gem: 1991 Mercury Capri

Ford has gotten a lot of use out of the Capri name in the United States. First, there was the Lincoln Capri in the 1950s, followed by the Ford Capri Mk1 (which was sold by Mercury dealers in the USA but never actually badged as a Mercury). Then came the 1979-1986 Mercury Capri, built on the very successful Fox Platform and essentially a clone of the Mustang. Finally, in 1991, the Australian Ford Capri came to the United States. Here is an example of this rare car that I spotted in a Northern California self-service yard not long ago. Mechanically speaking, the 1991-1994 Capri was a Mazda 323 under the skin, complete with a member of the same B-series engine family that went into such cars as the Miata and Ford Escort. So, for a few years in the early 1990s, car shoppers who wanted a sporty Mazda convertible could choose between a Miata and a Capri. The Capri had front-wheel-drive, but could be had with factory turbocharging. These cars were reliable and fun, but had a tough time competing with the Miata in the showroom battles. You'll see the occasional example now and then, but most of the 1991-1994 Capris have met the same fate that awaits this one. Related Video:

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.
