Teutonic cars don't really do well in the naming department. You've done well here to come up with a plausible one. They [Teutonic cars] are what they are. Characterless is a positive attribute in this case. Characterless and superbly proficient at doing the job they are designed to do. I have a Bosch washing machine. Does it have a name? No. Glad you're enjoying your new appliance!!
