Ford dissects the heart of the 2015 Mustang, its engine range

Happy Mustang Day. Are you tired of hearing about the 2015 Ford Mustang yet? No? Good, here's a bunch of mechanical data on Ford's sixth-gen muscle car, along with cutaways of the GT's 5.0-liter V8 and the new 2.3-liter, EcoBoost four-cylinder shown above. We also have a smattering of info on the Stang's updated transmissions and an exploded-parts-diagram view of its all-new independent rear suspension.
Ford is set to make waves offering the Mustang with a turbo for the firs time since the small-volume SVO of the 1980s. Displacing 2.3 liters, the engine's twin-scroll turbo should help the four-cylinder turn out a projected 305 horsepower and 300 pound-feet of torque, while also returning the best fuel economy in the Mustang's engine lineup. As we said in our Deep Dive, the EcoBoost will be slotted in as a premium engine, above the 3.7-liter V6 but below the 5.0-liter V8.
Speaking of that high-revving eight-cylinder, it's receiving a new cylinder head with high-flow ports. The intake and exhaust valves are larger and the cams have been replaced, among other tweaks. It should rev even higher thanks to a rebalanced crankshaft and forged connecting rods. Ford is still claiming a projected 420 hp and 390 lb-ft, although as many of the changes for the 2015's V8 come from the 2013 Boss 302, we're going to assume there's some sandbagging at work.

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.

Watch Tanner Foust hustle the Fiesta ST 'round the 'Ring

The last time we saw Tanner Foust at the Nürburgring he was sloshing an SVT Raptor from kerb to kerb. Sticking with Ford but swapping keys, this time the drift champion and Top Gear USA host goes to the opposite end of the manufacturer's tuner garage and plucks a Fiesta ST for 'Ring duty.
The 179-horsepower front-wheel-driver acquits itself well by the end of the video. But be warned, Foust doesn't set a 'Ring time and it's shot like a commercial... because that's what it is. Still, you can enjoy all two minutes and 31 seconds of it below.
