Those against it said engines are critical to brand identity and determine vehicle performance characteristics.
"Brand loyal people will not be happy about cross sharing engines," a dealer wrote. Another favored sharing transmissions but not engines, adding that any sharing of parts or systems must be disclosed to customers.
Transmission sharing was less controversial, with nearly two-thirds of respondents saying increased sharing would be good. "Maybe we could get rid of the bad ones," one dealer wrote. "There are plenty of bad ones!"
Sharing axles and other hidden components drew even more support. Automakers can maintain exclusivity with proprietary exterior and interior designs, one dealer wrote.
Another dealer boiled it down to this: "Consumers would prefer something reliable, durable, proven, and if they were aware it helps keeps cost down, that would be a plus."
