I guarantee the advertising campaign hurt sales. http://jalopnik.com/this-cadillac-elr-ad-will-make-you-hate-electric-car-bu-1519987554

@Robert Fahey: Wow, I just watched it and I totally agree. Shooting themselves in the foot. So many great engineers at GM, and such an incompetent management. The story of the last 25+ years.
To me this does not exactly look like the car to take on the Tesla, sorry. The Model S is far better looking, way more usable, way more spacious, has a better user interface, gets rid of the need for gas, and has no combustion engine to worry about. It's aluminum, and will out-last me.
My Model S will still be rolling strong when most 2014 ELRs are being sold by the pound, 10 years from now.

$76k for 56kms range and they say they can compete with Tesla. I think that was a bit off the mark and should be retracted. This isn't even a round trip to the supermarket.

Um.... no. Not at all. The ELR is an overpriced Volt with less doors and less practicality. Its a coupe. But normally coupes are fun and lively. But with this thing being in the price range of an M4 or CTS-V, it isn't that either.
The base price of a Model S is actually LESS than that, and for that you get a car that has the cargo room of a small SUV, the carrying capacity of 5 adults plus optionally 2 rear jump seats, more performance, better safety, more technology.
Not to mention the way the two different companies actually take care of their customers. Yes, sorry, had to add that.
The only thing the ELR has for it is its total range. Thats it.

How does the Warranty stand up against the Tesla benchmark?

the ELR is an overpriced volt. I wouldn't compare this with the tesla, but more of an upmarket volt. Not worth the coin IMHO. Does not have the electric range or performance of the Tesla. If sold for $50k, the nicer styling and trim would be worth it, but at the cost of $75k, this is nothing more than a next generation Cadillac Cimarron in hybrid garb.
An attractive, well equipped cimarron, but about $25k too much

I tried to take a test drive in an ELR, I really did. Having booked a test drive, and spoken to the dealer that morning, I get there to find they didn't have one that could be driven. The salesman couldn't understand why I didn't want to just sit in it.
The Tesla dealer was incredibly pleasant experience, with no pressure, and a full tour of the shop, including the (spotless) service bay.
I'm not looking to buy right now, I'm still taking notes, but the Cadillac is out of the running - if that's how they treat people when they want their money, I shudder to think what they'd be like in something like a warranty claim situation.

First, I think the Volt is a pretty good platform and 38 miles of EV is more useful than people think but at $500/kWh and 16.5 kWh the Volt and ELR use a $8,250 battery and the ones in the tesla are $30k and $42,500 respectively.
Tesla has a good reason to be expensive and its still cheaper than a base ELR. As Richard said Tesla offers a lot of other useful features too.
I can sort of see why people don't see enough value in the ELR. The Volt itself is actually a decent platform because most trips are significantly shorter than 35 miles. GM did a study of Volt owners and discovered people got on average about 900 miles per tank.
The average trip in an automobile is only like 6 miles and most peoples commutes are under 20 miles so most people can get to work and back on EV alone and even if you do tap into some of the fuel its only for a couple miles. If you can charge at work you can stay in EV for a large percentage of your driving.
People underestimate the usefulness of plug in hybrids. Even only 10-15 miles of EV range can have a huge impact on overall fuel consumption. To give an example if you drive 30 miles to work each way and use EV for the first 15 of it and get 40 MPG for the last 15 miles, ignoring electricity your average is 80 MPG instead of 40 and you can do it with about $3000 in batteries. In a couple years it will be possible with $2000 in batteries as Li-Ion prices drop to the $300/kWh range.

Looks like it fails on too many counts! And that is not even counting the incompetent dealership.

"$76,000!!
That is in the same price category as the Tesla Model S, (130mph top speed 0-60 in less than 4.5 seconds) described as the best car in the world by several critics and publications. It is laughable that they charged so much for this lackluster car.
