No way #2. Sorry, but Wright Aeronautical (as in Wilbur & Orville) had the first sodium valves in the mid '20s. Cheers, jeff

No way... TRW had the first sodium valves.. although VW did introduce the first compound curve multi layer PCB with surface mount LEDS for shift indicators when they could have used a setup a thousand times cheaper with light pipes and the same results, and don't forget the first door hinge bolt that has no access for removal unless the whole crash bar and dashboard come out first... oh and the first spare tire powered windshield wipers.. I think VAG has something like a 1 in 10 good/crazy idea ratio. The vanagon as a whole was a 1, specific parts of it definitely in the other 9 :) Jim ________________________________________ Bostig Engineering Engine Systems Voodoo http://www.bostig.com/ 617.272.3800

Just another bit of "engineering advice" GM picked up from VW?
