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.

2015 Ford Mustang EcoBoost

Earlier this week, Ford invited us to Charlotte, NC, to ride in an all-new 2015 Mustang fitted with its turbocharged 2.3-liter EcoBoost four-cylinder. It's the first forced-induction, four-cylinder ponycar for the Blue Oval since the sun set on the 1986 Mustang SVO. We jumped at the opportunity, as only a handful of people have ever been in the passenger seat of this new car, and most automotive media won't get as close as we did until this fall.
As we revealed in our Deep Dive, Ford will slot this new turbocharged four as premium powerplant between its naturally aspirated 3.7-liter V6 and the naturally aspirated 5.0-liter V8. At last mention, the automaker said the direct-injected, all-aluminum engine will develop 305 horsepower and 300 pound-feet of torque, returning the best fuel economy of the three powerplants in the process. History buffs will note that those figures are appreciably stouter than the 200 horses and 240 lb-ft that the '86 SVO realized out of the same displacement, and the latter's figures were hugely impressive at the time. On paper, the new EcoBoost four looks to be a good fit for most owners who want to balance performance with efficiency - we were eager to see how it felt from the passenger seat.

2015 Ford Mustang EcoBoost flogged and analyzed by Ignition

Aside from the way it looks and perhaps its independent rear suspension, the biggest bit of news on the 2015 Mustang may be the inclusion of its 2.3-liter, turbocharged four-cylinder engine. That blown mill marks the first time since the Mustang SVO of the '80s that a turbo has been fitted under the engine of Ford's pony car.
The Mustang EcoBoost is the subject of the latest episode of Ignition from Motor Trend, giving us a great look at the technical, nitty-gritty side of the turbocharged coupe. Covering it from bow to stern, host Carlos Lago walks us through the boosted Ford before taking to the track for some driving impressions, with particular praise given to the low-end grunt of the 2.3-liter mill.
Check out the full video and then let us know which 2015 Mustang has your interest piqued the most - the EcoBoost four, the 5.0L V8 or the entry-level V6.
