Although Ford's being doing it tough over the past few years, the current-generation S197-platformed Mustang has been a runaway sales hit since its launch in 2005. Now Ford is giving its reborn ponycar its first serious freshening. The basics will remain the same, but the workover will be thorough. Coupe and convertible bodystyles will still be offered, with V-6 and a variety of V-8 powertrains.
But here's the shock news: We hear there is a faction at Ford seriously contemplating fitting the new twin turbo EcoBoost V-6 to the 2010 Mustang. As they try to figure out how to meet 35mpg CAFE by 2020, Ford engineers are wondering whether the V-8 has a long term future. The EcoBoost engine, which is currently scheduled to debut in a performance version of the Fusion, could be the more fuel efficient alternative for Mustang in the long term. Depending on spec, the EcoBoost is capable of up to at least 415hp, and has the torque to match a regular V-8.
Traditionalists need not worry, though - V-8s will still be very much part of the Mustang program for 2010. If the EcoBoost version does make production, Ford would probably offer it alongside the V-8, and let buyers decide which they prefer. There won't be much of a price difference, if any - although the base V-6 is a cheaper engine, by the time things like turbochargers are added it's basically V-8 money, say our sources.
Don't expect any changes in today's, base 4.0-liter V-6 offering, as its prime purpose is motivating low-end and rental-fleet Mustangs. But the Mustang GT model's V-8-currently a 4.6 liter, SOHC, three-valver-will be replaced by a new 5.0-liter engine that's essentially an evolution of the old architecture. In fact, the new 5.0 may even appear in a limited edition run-out series of current model Mustang GTs - is it finally time for the reborn Boss 302?
One Ford engineer confirmed that the work done to create the Bullitt-edition Mustang's uprated 4.6 "has a future." That engine, described in our first test story (January 2008) remains internally stock, but breathes better due to a Ford Racing open element, cold air intake system, revised mufflers, a new crank damper (which ups the redline by 250 revs), and revised fuel mapping. This engine management programming allows the use of regular fuel, but switches to a more aggressive timing curve when it detects premium in the tank. The result is 315 horsepower, up from the current GT's 300. The Bullitt's V-8 is freer and quicker revving than before, and sounds great due to the new intake. There's no reason to think the next gen GT's powerplant won't take its cue from this technology, and thus get the same tricks. Something like 325 to 350 horses out of the new 5.0-liter V-8 sounds feasible.
Our intel had the 500-horsepower, supercharged 5.4-liter V-8 in the Ford Shelby GT500 pegged for a two-year or so life-that being 2007 and 2008, perhaps rolling into '09 depending on how well it sold, and what Shelby's own product plans were. Demand has proven strong, and we can confirm there'll be a Ford built, developed, and produced Shelby GT500 version of the 2010 Mustang.
