Ford unveiled its significantly-updated 2011 Super Duty truck today at the Texas State Fair in Dallas. Coincidentally, this is also the location where Ford decided to unveil the 2008 Super Duty as well. By far the biggest news associated with the new truck is its all-new engines, specifically the diesel offering.
For the first time in Super Duty history, the diesel engine is not sourced from International. It is an all-new designed developed in-house using a lot of the experienced gained from more than a decade of advanced diesel development in Europe. Although Ford hasn't "officially" released power figures for the new engine, the numbers of 400 horsepower and 725 lb./ft. of torque have already leaked their way out, and Ford hasn't exactly gone out of its way to dispute these now class-leading figures. The engine is first in its class to use a compacted graphite iron (CGI) block, which is lighter than conventional cast-iron, but has high strength. Similar to GM's Duramax, the new engine has aluminum heads. Also similar to GM's delayed "baby" half-ton 4.5L Duramax, the heads are reverse-flow, with the exhaust ports inboard, and the intake ports outboard.
This also marks the debut of the so-called "Hurricane" 6.2L V-8 engine in the Super Duty. This engine replaces the 6.8L V10. Both the 6.2 gas and diesel engines are exclusively mated to a new 6R140 heavy-duty TorqShift six-speed automatic transmission. The 5.4 V8 remains as the base engine for now, although some expect it may be phased out eventually. By all reports, the manual transmission option is gone. The very low take-rate probably contributed to its demise. On 2011 Super Duty diesels with the PTO prep option, the PTO output gear is linked through the torque converter to the engine crankshaft. This allows the transmission to power auxiliary equipment such as snowplows, aerial lifts, tow truck lifts, cement mixers or dump trucks. The power is available any time the engine is running.
The trucks are expected to go on sale in the first quarter of 2010.
