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.

Nuclear-powered concept cars from the Atomic Age

In the 1950s and early 60s, the dawn of nuclear power was supposed to lead to a limitless consumer culture, a world of flying cars and autonomous kitchens all powered by clean energy. In Europe, it offered the then-limping continent a cheap, inexhaustible supply of power after years of rationing and infrastructure damage brought on by two World Wars.
The development of nuclear-powered submarines and ships during the 1940s and 50s led car designers to begin conceptualizing atomic vehicles. Fueled by a consistent reaction, these cars would theoretically produce no harmful byproducts and rarely need to refuel. Combining these vehicles with the new interstate system presented amazing potential for American mobility.
But the fantasy soon faded. There were just too many problems with the realities of nuclear power. For starters, the powerplant would be too small to attain a reaction unless the car contained weapons-grade atomic materials. Doing so would mean every fender-bender could result in a minor nuclear holocaust. Additionally, many of the designers assumed a lightweight shielding material or even forcefields would eventually be invented (they still haven't) to protect passengers from harmful radiation. Analyses of the atomic car concept at the time determined that a 50-ton lead barrier would be necessary to prevent exposure.

2014 Ford Fiesta ST priced from $21,400* [w/poll]

The 2014 model year brings a whole host of changes to Ford's Fiesta B-Segment fighter, the most important of which (to our enthusiast eyes, anyway) is the addition of a potent new ST model. The US-spec hot hatch was first shown at the 2012 Los Angeles Auto Show last November, and thanks to Ford's build-and-price site, we've now learned that the Fiesta ST will slide in at $21,400 when it goes on sale later this year (*not including $795 for destination).
Under the hood of the ST is a turbocharged 1.6-liter EcoBoost inline-four good for 197 horsepower and 214 pound-feet of torque, mated solely to a six-speed manual transmission. Ford hasn't released performance data on its pint-sized puncher just yet, but know that these numbers make the Fiesta ST ever-so-slightly more powerful than the larger Volkswagen GTI while returning an estimated 34 miles per gallon on the highway.
Elsewhere in the lineup, the standard Fiesta also gets a smattering of improvements for the 2014 model year, including a new 1.0-liter three-cylinder turbocharged engine and revised exterior styling. Pricing for the 2014 Fiesta sedan starts at $14,000, with the five-door model adding $600 to that number (again excluding the $795 destination fee).
