In the early 1990s, the Toyota Motor Company attempted to develop an aviation version of the Lexus engine. As a result, they teamed with Scaled Composites in 1991 to develop a fast, futuristic aircraft powered by a 250 hp version with 244 cubic inches of the 1989 Lexus V-8 powering the Japanese manufacturer's Lexus LS400 luxury car (Lexus is a division of Toyota). Scaled initially tested the prototype engine in the right nacelle of a Piper PA-23-250 Aztec N178AE (c/n 27-3189), designated the Lima 1 and certified to Dick Rutan's Voyager Aircraft in 1990. Only one photo of that aircraft is known (see left).
The Lima project was run by Yuki Togo (former head of Toyota Motor Sales, USA) and Jim Press (later head of Lexus), two very high level and highly regarded Toyota people. During the time that Mr. Togo and Mr. Press were in charge of the aircraft project they established Airflite, visited Oshkosh in the company's Gulfstream G-IV jet and took an interest in airshow activities. Lexus even sponsored Charlie Hilliard's 'Lone Star' racer. There is no clue as to the real meaning of "Lima", but it likely was an acronym. Someone suggested on a web forum that it could read as "Lexus In My Airplane". Though this is pure speculation, it would certainly be in line with some of the other wacky acronyms — such as SCAT or SMUT — that Burt Rutan seemed to be very fond of for his programs at the time...
