Ford Taurus SHO
From Ford press: One of America’s favorite “sleeper” performance cars returns to the Ford lineup, powered by a Super High Output (SHO) EcoBoost twin turbocharged engine. The Taurus SHO joins Ford’s growing lineup of performance vehicles for the 2010 model year, building on the legacy of the original, which earned a spot on the Car and Driver 10Best list four years running.
Introduced in 1989, Taurus SHO was conceived as a discreet performance-oriented sports sedan, ideally suited to the automotive enthusiast needing the room and capability of a four-door full-size car. Produced through 1999, more than 100,000 were sold.
The original Taurus SHO generated a loyal following of owners and enthusiasts, with an active club more than 1,000 members strong, an online forum with more than 10,000 registered users and a Web site (bringbackthesho.com) specifically devoted to convincing Ford to resurrect the SHO. The 2010 Taurus product development team spent significant time listening to SHO enthusiasts.
The foundation of the new 2010 Taurus SHO is a 3.5-liter twin-turbocharged EcoBoost V-6 engine. This advanced powerplant generates 365 horsepower at 5,500 rpm and 350 ft.-lbs. of torque from 1,500 to 5,250 rpm, resulting in significantly improved power, flexible torque and fuel economy compared with larger, normally aspirated engines. This also is Ford’s most powerful EcoBoost engine.
A key feature of this EcoBoost engine is gasoline direct injection. The direct injection of fuel into the cylinder during the intake stroke, as opposed to port-style injection to an externally mounted intake, produces a well-mixed air-fuel charge. Fuel vaporization during the intake stroke cools the incoming air, improving volumetric efficiency and lowers the likelihood of knock.
The results are improved throttle response, reduced cold start emissions characteristics and improved fuel economy. The cooled charge enables an increased compression ratio, improving efficiency at partial load, while the higher compression ratio allows for better volumetric efficiency under full load engine behavior. Customers will experience normally aspirated V-8 power, without compromising V-6 fuel economy.
The 3.5-liter EcoBoost V-6 also uses twin turbochargers, as opposed to a single unit. The reduced size of each turbocharger results in reduced internal inertia, allowing this advanced engine to avoid the “turbo lag” often prevalent in earlier-generation turbocharged applications. From the driver’s seat, the rewarding result is linear power delivery across a broad torque band from 1,500 through 5,250 rpm. Peak torque building quickly off idle ensures responsive acceleration from a standing start.
