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.

Top torque-to-weight ratios under $100k, $50k and $25k

Horsepower may steal a lot of headlines, but the always-more-complex torque figure is often a critical one for both the workingman and the motoring playboy. The measure of rotational force represents the twist that can liquefy one's tires or haul one's horse trailer. Good stuff.
It follows then, that as with the horsepower-to-weight list that we assembled for you a few months ago, a list of cars that offer the most pound-feet with the fewest pounds to carry, is an interesting one to break down. Sure, there's a big difference in how the torque is applied from a turbocharged six-cylinder in a Swedish luxury sedan and a massive heavy-duty truck's turbo-diesel. But being the car/stat geeks that we are, we think it's kinda neat that those two vehicles rank near each other where torque and weight intersect.
As with the horsepower list, we've given you figures as pounds per every one pound-foot. Again broken down into broad price categories, we've got a mixed bag of 2014 and 2015 models here, too. Every effort has been made to select the most up-to-date prices and specs, and we've also to omitted some '14 cars that won't be re-upped after the ongoing yearly changeover.

2015 Ford Expedition stays the course, adds EcoBoost power

The era of the body-on-frame, fullsize SUV is rapidly vanishing in favor of smaller, unibody crossovers. However, Ford still sees life in the segment with the reveal of the updated 2015 Expedition, now available (solely) with the company's 3.5-liter EcoBoost V6. The new truck will make its public debut at the 2014 DFW Auto Show in Dallas on February 19.
The loss of the previous 5.4-liter V8 in favor of Ford's 3.5-liter, direct-injected, twin-turbocharged V6 engine might rankle some of the Expedition's fans, but Ford claims that the change gives the SUV better fuel economy, more power and increased low-end torque than before. Unfortunately, official engine specifications won't be released until later this year, but Ford says engine output will be similar to the 365 horsepower and 360 pound-feet of torque that this powerplant produces in other applications. The EcoBoost is mated to a six-speed automatic transmission, and the SUV now uses electrically assisted power steering, for an even greater fuel economy advantage. Ford claims this also allows for better maneuverability at low speeds and better feel at high speeds.
Exterior styling is basically unchanged for 2015. The front end has the same three-bar chrome grille and headlight design, but the lower air dam gets added chrome and LED lamps. The rear gets more brightwork on the hatch, and there's a chrome-tipped exhaust pipe. As before, Ford is offering the Expedition in two wheelbase lengths - 119 inches and 131 inches. A new, optional, continuously controlled damping system alters suspension settings constantly based on 46 parameters and offers comfort, normal and sport modes (just like the Expedition's sister, the recently refreshed and decidedly less-attractive Lincoln Navigator).
