– Ford Motor Company earned two spots on the Ward’s 10 Best Engines list for 2007. Mazda also earned recognition for its DISI 2.3L turbocharged DOHC I-4. Along with the 3.5L V-6 Duratec engine, Ford’s 4.6L V-8 made the top-10 list. The winners were selected by Ward’s staff out of a field of 31 production vehicle engines from around the world. An option in the Mustang GT and the Explorer, the 4.6L V-8 seemed to be a favorite with the Ward’s panel. They praised its “exuberant power delivery” and noted that it was “more than just a muscle car V-8.”The 4.6L aluminum V-8 has three valve heads and cranks out 300 horsepower. The engine also produces more than 50-percent more power than the small-block 289-cubic-inch V-8 did in the classic 1964½ Mustang. As the optional V-8 in Explorer models, the engine also delivers low emissions and complies with California’s Low Emissions Vehicle II (LEV II) standard.In the Mustang, the engine is also available in a Shelby GT package that bolts on a Ford Racing Power Pack to boost power by an additional 25 horses. The Power Pack consists of a cold-air intake, a revised crossover pipe for the dual exhaust, and engine management software. Ford also offers the 4.6L engine in the Explorer and Explorer Sport Trac models.
