Paisley, Florida | April 4, 2011

Turbine Truck Engines, Inc. (“TTE”) (OTCQB: TTEG), announces that the assembly and initial pre-test alignment and runs have been successfully completed for its 6th Generation prototype DCGT engine. TTE took delivery of the parts on March 9th. Since that time the engine has been undergoing assembly and pre-test checks at the Gas Turbine Laboratory at Embry-Riddle University in Daytona Beach, Florida.

"The engine assembly is coming along really well. All parts are within tolerance and the fit is excellent," commented Dr. Magdy Attia, TTE's Chief Technical Officer. "This new prototype is a considerable improvement over the previous generations in terms of material selection, design of the flowpath, and clearances," said Michael Rouse, TTE's President and CEO. Preliminary alignment checks and pre-test dry runs have been conducted to verify running clearances, which are considerably tighter than predecessor prototypes. All results show the engine is assembled as designed with no issues. The engine will be disassembled for a final inspection. Full scale testing is scheduled to commence in the next few weeks.
