Is the upcoming Cadillac ELR a threat to the Tesla Model S?  And will Tesla Model S customers cross shop the ELR?

That is the question posed by CNBC and their correspondent Phil LeBeau.

From our prospective, given that GM has said that its luxury extended range Cadillac will be priced from $75,995 and will only offered in limited numbers when it is introduced in January 2014, we would suggest it is not.

However, if the 35 mile extended range Cadillac ELR is met with high consumer demand there is no reason to expect GM would not continue to produce the luxury plug-in from their Hamtramck, Michigan assembly facility indefinitely.

Also of note: The Cadillac ELR will also come in a Saks Fifth Avenue Edition. Limited to just 100 units, this special ELR will retail from $89,500
