The 'correct' hybrid has a diesel engine sized to move the vehicle down the road at highway speed, fully loaded and with a few ponies to spare, and sufficient battery capacity to handle normal acceleration and regenerative braking needs. And, obviously, sufficient electric motorage to give the desired driveability characteristics. Not REV, not a big diesel with a little electric motor. Not a gasser of any sort. The batteries are the most evil part of a hybrid, you want to minimize them. Average drive power is all fuel, all peak needs met electrically. HVAC completely traditional, driven off the diesel. Diesel can stop at lights, if the battery charge is sufficient and you have a coolant circulation pump ala MB to heat during stops from residual engine heat. Motor will start if cabin starts to cool. (Webasto-style fueled heater even better, but is a bit on the expensive side. Will forgo. Must use diesel waste heat rather than fuel when available, anyway.) I'm thinking a 20HP diesel with maybe 100HP of electric motor. The diesel needn't be a turbo, but if it's more efficient on the highway with one then it should have it. Battery pack relatively small, would only take you a few miles on its own. _That_, in AWD sedan form, I might buy. Provided it had a traditional fail-safe key switch and no stupid shrubbery on the dash. And got an honest 60 MPG. -- Jim _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
