Cadillac Converj

After the $4 gas price spike in mid-2008, global car companies quickly adopted the near unanimous goal of producing greener more fuel-efficient cars for the masses. But opinions about how exactly to drive down the inherent cost of hybrids, electric cars, and clean diesel vehicles—to make these technologies affordable and commonplace—have broken down into two camps.

Hybrid stalwarts Honda and Toyota are making a move to capitalize on their early investment in gas-electric technology by increasing production numbers, lowering costs, and offering hybrids for around $20,000. Electric car and plug-in hybrid startups, Tesla and Fisker, are hoping to enter the market with exotic green machines in the neighborhood of six figures—and then to demonstrate profitability, and slowly work toward follow-up models at $50,000 or below. General Motors is somewhere stuck in the middle when it comes to its plug-in hybrids, like the Chevrolet Volt.

The Volt likely will carry a sticker price around $40,000—steep for a Chevrolet product—and still not turn a profit for years. Bob Lutz, GM’s product czar, said, “In terms of recovering the cost from the technology, doing it in a Cadillac would have made it financially easier to do.” We don’t have to wonder what a luxury version of the Volt would look like. The company unveiled the Cadillac Converj concept vehicle at the 2009 Detroit Auto Show.

Why a “Cadi-Volt”?

Built on the mechanicals of the 2011 Chevrolet Volt, the Cadillac Converj won rave reviews at the show, with its aggressive coupe profile, angular lines, and sleek, elegant exterior. An Escalade Hybrid, it definitely ain’t.

Those underlying mechanicals, now known as Voltec (nee E-Flex), are largely unchanged for the Converj. They include a 16-kilowatt-hour battery pack powering the 120-kilowatt electric motor that drives the front wheels, for an all-electric range of 40 miles, with a range-extending 1.4-liter engine to power a generator that recharges the pack for another 300-plus miles of travel. While the control electronics might be retuned for slightly better performance, the Converj wasn’t about technical specs. A company press release states: “The four-passenger Converj concept is intended to show how GM’s revolutionary electric propulsion technology…can power a luxury coupe with a typically Cadillac ‘no compromises’ design.”

Cadillac Cues

The “aggressive, forward-leaning” profile is supported on large wheels and tires: 21-inch diameter in the front, 22 inches at the rear. A glass roof incorporates solar panels that can power vehicle accessories, and like the Volt, the Converj minimizes aerodynamic drag. It has a full belly pan to smooth airflow below the car, the grille openings are minimal, and its outside mirrors were even replaced with video cameras to eliminate the drag they added.

Now-traditional Cadillac style cues include the light-pipe technology in the vertical headlamps and tail lamps, fitted with light-emitting diodes (LEDs) and high-intensity discharge elements.

The Converj also uses the Magnetic Ride Control suspension pioneered on Cadillac’s pricey XLR two-seater. In this system, damping is provided by electrorheological fluid whose viscosity changes millisecond by millisecond as a magnetic field affects the magnetic particles suspended in it.

The Cadillac theme of “art and science” is most visible inside the concept, which blends high-tech electronics with luxurious materials.

Black leather and white synthetic suede upholstery is matched to aluminum and wood-grain accents, and the designers attempted to use sustainable materials. The suede comes from “post-industrial content” (when was the last time you heard that about a Cadillac interior?), the carpeting blends in real wool, and the headliner is made of silk.

The instrument cluster uses an organic light-emitting-diode (OLED) display, just like the crispest and priciest monitors. All the controls are operated through a touchscreen (think iPhone), and the exterior cameras that supplant rear-view mirrors display their images on a screen high in the instrument panel.

Aerodynamics and Cash Flow

But let’s hope that its stylists did their homework on the aerodynamics. If the Converj goes into production, we hope it won’t vary as much as the 2011 Volt does from the very different shape of the concept shown in 2007, which was striking but proved wildly un-aerodynamic. The design of the Volt’s more aerodynamic production version is much more sedate. The Dallas Morning News said it “looks like the quintessential rental car.”

Perhaps Lutz and the gang are still smarting from criticism about those design changes. At the Detroit Auto Show, he emphatically stated that if the Converj goes into production, it will look “exactly like” the concept version. That’s a big if. Before the Converj goes into production, according to Lutz, GM has to prove four things: that the company has the money to make the vehicle, that it’s a higher priority than other vehicles in the works, that the Converj can make money, and that there’s customer interest. “It’s going to be financially tough sliding,” said Lutz.

    The backseat does not look very practical. I assume that the interior is show case only and then a possible production model would be a little bit more baby seat friendly.

  • Shines

    I say forget the back seat. The car looks like a 2 seater to begin with. Use the extra space to add more battery and increase the electric range (or improve the performance) of it.

  • J-Bob

    Make it a 3 seater. More space for batteries and groceries.

    All I know is if they went with this design vs the concept/production Volt look, they would’ve sold a lot more cars.

    Vanity is an American way of life 😉

  • Collin Burnell

    I say build a Volt for all the (surviving) divisions of GM!!! A Saturn version, a SAAB version, an Oldsmobile version… oops! Sorry!

    A Pontiac version could be very cool as well… A Voltice!!

    But the Converj is georgous!!!

  • GR

    3 seats wouldn’t be practical for everyday use. Make it 4 seats (ie: a couple and 2 kids, or 2 couples).

    Maybe they should’ve taken a cue from Tesla on this and debuted their more expensive one before their less expensive one. Make money off the Converj and then work their way down to the Volt.

    It does look really nice though so I hope this goes into production.

  • B. Nicholson

    Lunacy. If GM could be forced to lower coefficients of drag, maybe we would get some 1930’s advancements in aerodynamic efficiency sufficient to end imported mid-east oil. 60% of energy use is pushing air out of the way for road vehicles. We can do soooooooooo much better than this absurdity. Enclose wheels, add boat tail, smooth the bottom. Get rid of all the fluffy anti-aerodynamic junk all over it.

    awesome pure awesomeness

    Nice, hopefully will own my own.

    ohhh my goshh i want this to be my very first car.
    i don’t even want to dare try driving a gas car anywhere.
    but why does it have to cost so much. they should point there products to the young people.
    bcause hey are the future. righhttttt.

    I recently purchased this vehicle and it is the most amazing experience to on one of these. LOL

    I think it should be a 5 seater so it can carry more people and be great for roadtrips

    As a proud owner of one of the first XLRs, as well as the new CTS sport coupe for 2011, Cadillac would have difficulty in producing a vehicle that would outdo my XLR. I deeply regret it has been discontinued! I think GM would be wise to develop a new sporty luxury vehicle and market it to the professional woman and dig into their wonderful past of automotive design and call it the “La Salle”. I believe they would capture the market and restore Cadillac’s reputation as the “automotive standard of the world”!!!

  • JMT

    If Gm Cadillac makes Cadillac Converj as the picture above, I am pretty sure that they will sell tons of Converj cars.
    It is just beautiful car !!!!
