Our spy photographers managed to spot something curious (and decidedly hilarious) recently. General Motors has been busy testing what would appear to be Chevrolet Volt models with massive 20-inch wheels and tires in place of the low-rolling resistance pieces on the stock plug-in.

Why? Guesses are slim at the moment, but one hypothesis is that this is actually our first glimpse at a Cadillac Converj test mule. That vehicle will make use of an altered version of the Voltec drivetrain found in the Chevrolet, albeit bolted to flashier wheels. The luxury hybrid has been an on-again-off-again affair for General Motors since the concept first rolled across the stage at the 2009 Detroit Auto Show.

Last we heard, the Converj is on track for launch in either 2013 or 2014. If true, now would be the time to begin working out any engineering bugs on the rumored Voltec 1.5 system. With luxury buyers more willing to hand over stacks of cash for new technology, the Converj could make quite a bit more sense to buyers than the Volt. Or bolting chrome dubs to a hybrid, for that matter.

      Hopefully the ELR will be out in time for all the Karma trade-ins and cancelled orders.

      Now that gas is approaching $5/gallon in some areas, the Volt will start selling more. I wish GM would offer a version with a LPG powered engine. Cheaper , cleaner fuel, which can be stored for a very long time.

      I thought the name was ELR, not Converj?

      Might using the Volt technology in a Caddy almost be the 21st century equivalent of using Chevy ICE in an Olds or Buick? Will those able to lay out the "long green" needed to get into a ELR care that they are driving a $55k (guessimate) Chevy?

      GM rushed the Volt to market, and really should have waited until AFTER they could make a Converj, amortize the costs by putting the drivetrain in multiple vehicles, and the Volt would then come to market closer to $30k in the first place. A bankrupt GM isn't going to be able to compete with the Toyota's of the world without a business plan. They tried, and failed. Again...... LOVE the Converj Concept! Can't wait to see it in production. BD

        You're so clever Edward. Wonders never cease. If you're referring to the practice of relying too much on bad badge-engineering jobs I have just one word in response to yours: Lincoln

        Yeah because changing the rims on a car is just sooooo difficult. :facepalm:

          putting 20" on a hybrid and not losing fuel economy is difficult. I also would like my volt with this size wheel as an option.

      GM shut down the plant that builds the VOLT due to no one buying them...SO in normal GM thinking lets build and other car with a diff grille and wonder why it STILL does not sell

        1. $40,000-50,000 for a cadillac makes more sense than paying that much for a Chevy. 2. the Converj concept is beautiful 3. The Opel version of the Volt is selling very well...so it does have some sucess other places. I still believe they should have made the U.S. Volt look like the Ampera

          If the Chevy is 42 grand, how much do you think the Caddy will be? 70..I drive a 2010 Caddy and I dont see too many Caddy, BMW, Audi, MB, etc people running out to buy a small badged up Chevy Cobolt. Will they sell SOME,...sure

      I find the caddy beautiful piece of artwork while I see the volt as a prius competitor in ugliness. I ll much rather have the svelte focus hybrid.

      I don't get why they think this could be a Cadillac test mule just because it has aftermarket wheels & tires?

        It has manufacturer plates and it was seen right outside GM's Milford proving grounds.

        And there's at least two of them shown in the picture gallery, a black one and a silver one, with the same wheels. Sounds like development work to me.
