Five years ago Ford debuted the F-350 Tonka Concept, a big yellow concept truck that portended the design of future Super Duty trucks. Along with the chunky looks, the Tonka concept also featured a trick bit of eco-tech called Hydraulic Launch Assist (HLA). The system uses a hydraulic pump/motor and high pressure accumulator to recapture kinetic energy when braking, which can then be released when the truck is accelerating to assist the engine. It's a type of mild hybrid system really, though its effect promised to be substantial.

Rumors are swirling around the intertubes that a production version of Ford's Hydraulic Launch Assist technology will debut with the 2009 Ford F-150 at the Detroit Auto Show, or possibly a year later. A figure of 60 mpg was initially thrown around, though we're a bit skeptical a production version of HLA could hit the mark. A similar system, however, has already reached the roads on some special Hydraulic Hybrid UPS trucks that were developed by the EPA in conjunction with Eaton and International Truck, both of which are Ford suppliers, as well.

There's been no confirmation from Ford that the 2009 Ford F-150 will feature HLA, so we'll have to wait until January when the new truck is unveiled in Detroit to find out for sure. If HLA does make an appearance, it'll be the second major shake up in the full-size truck segment debuting in Detroit, the other being Dodge's switch to a coil-sprung rear suspension on the 2009 Ram.

Detroit 2008 Preview: 2009 Ford F-150 could add hydraulic launch assist

Filed under: Hybrid, Ford, Detroit Auto Show

One of Ford's most important debuts at the upcoming Detroit Auto Show is the new 2009 F-150. While Ford doesn't have a gas-electric hybrid system suitable for big trucks like GM's Two-Mode system, they will have offer some technology to improve fuel economy and emissions. Back in 2002 at the Detroit Show, Ford showed a concept called the F-350 Tonka. The Tonka truck featured a technology called hydraulic-launch-assist (HLA) which will debut on the new F-150.

The HLA system functions in much the same way as the hydraulic hybrid system we saw on an experimental UPS delivery truck earlier this year. A hydraulic pump/motor is connected to the drive shaft along with a high pressure accumulator. During braking the pump/motor is driven to pressurize the accumulator and recapture kinetic energy. During acceleration the pressure is used to drive the motor and provide a boost so the engine doesn't have to work as hard. Essentially it acts as a mild hybrid system without the automatic start-stop functionality.

I hope that Ford really brings the system for the new F150 because this could bury the other hybrids
