In memory of Dave Hermance – Toyota Spokesperson, Technical Expert and Great Friend of the Prius Club of San Diego


The Prius Club of San Diego has lost a great friend and tireless source of technical information with the untimely death of Dave Hermance yesterday, November 25, 2006.  Dave was practicing aerobatic maneuvers when the single-engine Interavia E-3 he was piloting crashed into the Pacific Ocean off San Pedro.  

In the two and a half years that we have known Dave, he made himself available whenever possible, favoring our Club with outstanding and timely presentations on three occasions, the last just this past October 8 in Carlsbad regarding the latest battery technology.  Dave always brought something new for our members to experience…the Lexus 400h months before it was available for sale in the US, the new 2007 Touring Edition Prius…but most of all he brought his enthusiasm, expertise and willingness to share his knowledge.

Dave did this not in his official capacity with Toyota, but on his own time and at considerable sacrifice of his precious weekends.  Mary, his wife, accompanied Dave on his trips to join us and we found her equally engaging.  Our heartfelt sympathy goes out to her at this incredibly painful time.

We will miss you Dave and think of you every time we get in our Prius you had so much to do with bringing to the marketplace.
