Cadillac Reveals Converj Plug-In Hybrid Coupe Concept


General Motors unveiled a further glimpse at the potential of electric propulsion today, this time in the form the Cadillac Converj Concept. The new show car was developed as an upmarket GT with a bold design and a bevy of advanced powertrain technology.

The four-passenger Converj concept is intended to show how GM’s electric propulsion technology – called Voltec – can power a luxury coupe. The technology enables up to 40 miles of petrol and emissions-free electric driving with extended-range capability of hundreds of miles.

Cadillac’s extended-range electric vehicle (E-REV) concept has a new body style that is an evolution of the brand’s traditional Art and Science design theme, with an aggressive forward-leaning arc profile dominating the design.

The concept’s Voltec electric propulsion system is made up of a 16-kWh, T-shaped battery, an electric drive unit, and a four-cylinder engine-generator. It uses electricity as its primary source to drive the car. A thermally managed battery pack contains more than 220 lithium-ion cells that provide the primary power to drive the Converj electrically up to 40 miles without using fuel or producing tailpipe emissions. The battery is integrated into the Converj’s chassis and stores electricity from the grid when the vehicle is plugged in. It takes less than three hours to recharge the battery at 240V, or about eight hours from a 120V outlet.

When the battery’s energy is low, the Converj seamlessly switches to extended-range mode. During this secondary level of operation, electricity needed to power the vehicle is created on-board by a flex-fuel-powered engine that operates much like a home generator to create electricity.

Whether in electric or extended-range mode, the Converj is propelled all the time by an electric drive unit. It converts electrical energy from the battery or the engine-generator into mechanical energy to drive the front wheels. It also delivers 273lb-ft (370Nm) of instant torque, for a quick launch, and 120kW of power. The top speed is 100mph.

To enhance the ride feel, the Converj also features GM’s Magnetic Ride Control, and for greater efficiency, energy during braking is captured and stored in the battery.

Styling features include a sweeping body line with 21in wheels up front and 22in units at the rear. The concept’s exterior is painted a dark silver tri-coat called ‘Reaction,’ and is joined by an all-glass roof that incorporates solar panels to help offset power drained from the vehicle’s accessories.

Inside, there is a 2+2 configuration that is trimmed in contrasting white and black leather trim, as well as polished aluminum and wood grain accents.

  1. A luxury 2 door with a 1.4 liter turbo engine? Would there be enough masochist rich people to make this profitable?

  2. NND, if they sink in better electric motors, a more advanced battery, and a more aggressively turbocharged engine (remember, regarding the engine, the power of the engine really doesnt matter at all), theyll be able to sell a dressed up volt to the people who will actually be willing to pay for the development costs of the platform.

    its smart business.. and so long as it is given a lot of cadiness, then you wont end up with another cadilier.

    personally i think there will be a good market for high end hybrids with some serious get-up-and-go. just think of those gated communities that want you to do 10MPH to keep the neighbourhood quiet... well that really will make sense with hybrids.

    im just putting it out there.. if FIA isnt going to sanction a new hybrid racing series, then the development costs are going to have to be covered by well marketed luxury products where the profit margins are high. long gone are the days of the model T where a company could get off the ground making millions of cheap products.

  3. It's a winner in my eyes, going solely on looks alone. I'd purchase one if I had the dough.

  4. Uh huh Chris, what are you smoking? If your rich, your not buying a car with a 1.4 liter engine

  5. noname.. who's been buying the prius? surely not people who think its a great idea to buy a compact hatchback with no cargo room for 50% markup of comparable models... not to mention the fact that the prius has no balls what so ever.

    basically.. who do you think is buying hybrids? afluent people who think that the world IS going to hell and that THEY need to do something about it no matter how little sense it makes financially.

    id be willing to be that the majority of prius owners also own a vehicle that is valued over $50k... its why i think the escalade hybrid is such a good idea... its why i think a premium hybrid sedan is such a good idea.... the only other premium hybrid is that boat of a lexus that gets marginally better fuel mileage on an already dead expensive sedan.

    offer the volt at 30 grand and this sexier, more luxurious caddy version for 50 or 60 and you'll still sell out. hell.. if you were smart you'd pull a ford and release the caddy version first (MKS) and then a year later bring out the volt (Taurus)

  8. that interior is amazing... if it actually would come out like that, i hate it when car companies have great designs but r too tight arsed to bring it out, so hopefully for once i will like a roduction model interior of an american car.

  9. While the interior is in fact pretty - what the hell happen to the exterior? It looks like its been in a head-on collision with some sort of an origami crane.
