Cadillac Converj Concept Car

Cadillac Converj is the latest grand touring coupe car concept that has been unveiled by General Motors at the NAIAS. Powered by a 220 lithium-ion cells battery pack integrated in the chassis of the car, Cadillac Converj offers a range of 40 miles.

To fully re-charge from a 240V outlet, Cadillac Converj needs around 3 hours. While from a 120V, Cadillac Converj needs 8 hours.

The latest electric propulsion technology from the company called Voltec is showcased on this Cadillac Converj. With the new tech, Cadillac Converj may gets up to 40 miles of gas- and emissions-free driving.

Cadillac Converj also comes with some features include Touch-screen navigation, climate, organic light-emitting diode technology, center-stack controls and audio systems and a unique power on sequence featuring blue-lit console graphics.

Press Release
General Motors unveiled a further glimpse at the potential of electric propulsion today, this time in the form of luxury transportation, with the Cadillac Converj Concept. The Cadillac Converj was developed as a well-appointed grand touring coupe with a bold design and a host of interactive technology.

The four-passenger Converj concept is intended to show how GM’s revolutionary electric propulsion technology – called Voltec – can power a luxury coupe with a typically Cadillac “no compromises” design. The technology enables up to 40 miles of gas- and emissions-free electric driving with extended-range capability of hundreds of miles.

Bob Lutz, GM’s vice chairman of Global Product Development, said the Converj concept has production substance. “It’s a logical extension of our plan to reinvent the automobile,” he said. “It clearly shows what a Cadillac electric vehicle could look like, and clearly indicates that global luxury customers can have a car that has both strong design and electric propulsion with a total range of hundreds of anxiety-free 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. An aggressive, forward-leaning arc profile is the foundation for the sporting stance. And more than a Cadillac in form, Converj is also intended to be a Cadillac in substance, with the premium materials, technology and driving dynamics that are hallmarks of the brand.

Voltec – innovative propulsion technology

The Cadillac Converj’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. The engine-generator ensures a constant supply of power for hundreds of miles until the car is refueled or plugged in to recharge the battery. This extended-range mode eliminates the range anxiety that comes with driving pure electric vehicles that offer no backup power when the battery charge is low.

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 273 lb.-ft. (370 Nm) of instant torque, for a quick launch, and 120 kW of power. The top speed is 100 mph.

There is no compromise in vehicle performance in either mode of operation. To enhance the ride feel, the Converj also features GM’s Magnetic Ride Control; and for even greater efficiency, energy during braking is captured and stored in the battery.

Pure Cadillac design

There’s no mistaking the Converj for anything but a Cadillac, according to Lutz. “An aggressive, forward-leaning profile hints at a new, progressive theme and proportion in Cadillac’s design evolution,” he says. “The new proportion showcases a uniquely shaped, modern vision of a personal luxury 2+2.”

The overall shape is reinforced by a prominent, sweeping body line with large, 21-inch (front) and 22-inch (rear) wheels pushed to the edges of the body. The Converj exterior is painted a dark silver tri-coat that GM designers dubbed “Reaction.”

An all-glass roof incorporates solar panels that help offset power drain from the vehicle’s accessories. Additionally, several aerodynamic and design efficiencies were incorporated to enhance the driving range, including:

A full under-vehicle cover (belly pan)
Minimal grille openings that reduce drag at the front of the vehicle
Low-profile rearview cameras replace conventional outside mirrors to reduce drag
Wheels are shaped to push air outward for smoother body side airflow
The Converj also incorporates vertical headlamp and taillamp elements, with light pipe technology.

“Vertical lamps are Cadillac signatures and the Converj builds on the brand’s light pipe technology with bolder light emitting diode (LED) and high-intensity discharge elements front and rear,” said Clay Dean, global design director for Cadillac. “There is also a unique daylight light ‘spear’ at the top of the headlamps.”

Luxury meets technology inside

The Converj’s interior has advanced features and luxurious appointments blending efficiency and environmental consciousness. The 2+2 configuration is trimmed in contrasting Winter White synthetic suede – including the top of the instrument panel – and Midnight Black leather, with polished aluminum and wood grain accents. Renewable materials are used throughout such as wool-blend carpeting, a headliner made from silk, suede made from post-industrial content and more.

A technologically advanced driver center increases efficiency and reduces the draw on the battery. Features include:

New, organic light-emitting diode technology used on reconfigurable instrument cluster
Touch-screen navigation, climate, center-stack controls and audio systems
Adjustable, overhead white ambient lighting
Unique “power on” sequence featuring blue-lit console graphics
Screen displays for features including regenerative braking, battery charge level and power output
No inside rearview or outside mirrors; cameras provide surrounding images on a screen placed high on the instrument panel for a full, panoramic view
Push-button ignition and power-folding front seats

Cadillac unveils a new vision for the future of luxury transportation

Cadillac unveils a new vision for the future of luxury transportation with the innovative Provoq fuel cell concept – a hydrogen fuel cell crossover vehicle that continues GM’s commitment to displace petroleum through advanced technology.

The Cadillac Provoq fuel cell concept is the latest example of GM’s groundbreaking E-Flex propulsion system, combining the new fifth-generation fuel cell system and a lithium-ion battery to produce an electrically driven vehicle that uses no petroleum and has no emission other than water. The concept’s fifth-generation fuel cell technology is half the size of its predecessor, yet it has been developed to produce more power and performance.

"Cadillac is a natural fit for GM’s next step in developing the E-Flex platform,” says Jim Taylor, Cadillac general manager. "Cadillac, at its very essence, is about premium luxury, design and technology, so it’s fitting that Cadillac would be propelled by the most elegant solution. This signals Cadillac’s intent to lead the industry with alternative-fuel technology."

Fuel-cell variant of the E-Flex system

The concept can drive 300 miles (483 km) on a single fill of hydrogen – with 280 miles (450 km) from hydrogen and 20 miles (32 km) on pure, battery electric energy.

A pair of 10,000 psi (700 bar) composite storage tanks beneath the rear cargo floor hold 13.2 pounds (6 kg) of hydrogen to feed the fuel cell stack, located under the hood. There, hydrogen mixes with oxygen to generate electricity – up to 88 kW continuous power. A lithium-ion battery pack can store up to a total of 9kWh of electrical energy and also provides a peak of 60 kW of power for additional performance.

The electricity generated by the fuel cell is distributed to a 70 kW co-axial drive system for the front wheels and individual, 40 kW wheel hub motors on the rear wheels, giving the Cadillac Provoq its all-wheel-drive traction and great driving dynamics. Its 0-60 mph (approximately 100 km/h) speed of 8.5 seconds is a more than 30-percent improvement over the previous-generation fuel cell system and with instantaneous torque to the wheels, it feels even faster. Provoq has a top speed of 100 mph (160 km/h).

"This is a vision of what comes next – a fuel cell electric vehicle that delivers the driving characteristics Cadillac customers want and allowing them to do it without using a single drop of petroleum, while emitting only water vapor,” said Larry Burns, GM vice president for research and development. "This is proof that alternate fuels and advanced technologies create even greater opportunities to satisfy the luxury buyer.”

Key features

With sleek, signature Cadillac bodywork, the Provoq concept redefines luxury crossovers, offering uncompromising passenger and cargo space to match its performance and cruising range. Additional vehicle features include:

• Solar panel integrated in the roof to help power onboard accessories, such as the interior lights, audio system and more
• Brake-by-wire technology
• Front grille louvers that close at highway speed to enhance aerodynamics, and open at low speed to provide maximum cooling to the fuel cell stack

Purposefully dynamic design

The Provoq has a sleek, athletic shape that builds on the second generation of Cadillac’s design renaissance, led by the 2008 CTS, with dynamic and purposeful features that support the hydrogen fuel cell powertrain and contribute to the vehicle’s overall efficiency.

"All the people- and cargo-carrying capability customers expect in crossovers and SUVs is available in the Provoq, along with the premium attributes expected in a Cadillac,” said Ed Welburn, vice president, Global Design.

Highlights include:

• Active front grille, with grille louvers that open when the fuel cell stack requires cooling
• Full underbody aerodynamic cover
• Left- and right-hand charging ports incorporated in stylish front fender vents
• Flush door handles that feature push-to-release operation
• Wind tunnel-shaped outside mirrors with integral turn signals
• Center high-mounted rear stop lamp incorporated into full-width, wraparound spoiler
• Signature vertical taillamps with subtle fin design
• Side glass mounted flush with pillars
• Wheels with clear-covered space between the spokes, creating a sleeker profile while maintaining Cadillac’s signature bold wheel design
• Low-drag roof rack

"From the strong, shield grille and vertical headlamps to the crisp body lines, the Provoq is instantly recognizable as a contemporary Cadillac,” said Hoon Kim, exterior lead designer. "Like the new CTS, it is bold and expressive, but there is enhanced shape between the edges – it’s a new proportion for crossovers, with a fast, almost coupe-like rear.

"Everything about the vehicle reinforces the notion that great style and environmentally conscious transportation can go hand in hand,” said Kim. "We didn’t sacrifice proportion, stance or Cadillac’s iconic design cues; we used them to support the efficiency of the vehicle.

"They are the features customers expect,” he said. "The adaptability of the E-Flex architecture enabled the designers to create a great-looking vehicle, regardless of its alternative-fuel powertrain.”

Kim points to the fender-mounted charge ports as prime example. They allow overnight, plug-in charging that extends the driving range. The ports have a satin-chrome appearance that incorporates an amber light to indicate the system is charging and a green light to indicate when charging is completed.

"The ports are functional, but rather than hide them, they are design elements of the Provoq,” he said. "Sweeping body lines that culminate at the top and bottom edges of the ports suggest forward thrust, even when the vehicle is stationary.”

The vertical, neon-lit taillamps blend style with functionality, too, as their finned shape was designed to make the Provoq as aerodynamically efficient as possible.

Indeed, the Provoq has short overhangs and a sporty ride height that is complemented by large, 21-inch wheels.

The wheels are wrapped in custom Michelin tires incorporating Green-X technology. These low-rolling resistance tires feature a tread pattern that mimics the "H20” notation for water.

The tire designers and engineers at Michelin North America enthusiastically accepted GM’s challenge to create a custom low-rolling resistance tire to complement the energy efficiency and reduced environmental footprint of the Cadillac Provoq. During the past 15 years, the tire maker has developed four generations of Michelin green energy-saving tires, and the team’s no-compromises approach to the project helped reduce the Provoq’s overall fuel consumption without sacrificing road performance, grip and safety.

When used in conjunction with the other energy-efficient solutions featured on the Cadillac Provoq, the benefits of Michelin green energy-saving tires include:

• A reduction in the consumer’s overall cost of ownership
• An extended vehicle range through a more efficient use of on-board energy and its storage capacity
• A reduction of vehicle impact on the environment through lower CO2 and particulate emissions.

Uncompromising interior

Like the exterior, the Provoq’s interior blends style with function. It seats five and incorporates the comfort, convenience and infotainment features Cadillac customers seek. Most importantly, the fuel cell powertrain does not intrude on passenger or cargo room.

The hydrogen fuel tanks are mounted beneath the cargo floor, with the storage batteries located at the center of the chassis. The fuel cell stack is located under the hood, giving the Provoq the interior layout of a conventional crossover – including a full cargo area and a 60/40-split folding rear seat.

"The interior is roomy, well-equipped and offers the space people want in a crossover,” said Matt Erdey, interior lead designer. "There are no compromises inside the Provoq to accommodate the fuel cell powertrain and fuel tanks – a factor that proves the technology and real-world feasibility are growing closer together.”

There may not be compromising reminders of the powertrain in the interior, but the Provoq carries the instantly identifiable hallmarks of a contemporary Cadillac interior, with an expressive, well-crafted design.

"It picks up the cues, refinement and attention to detail of the new CTS and takes them to the next level,” said Erdey. "A contrasting color scheme, extensive use of ambient lighting technology and elements such as cut-and-sewn, hand-wrapped leather with French seams are elements seen in current Cadillac models, but they are amplified in the Provoq. "

The interior has a contrasting, dark gray and light gray color scheme, with chrome and satin-chrome accents throughout. Ambient lighting extends across the instrument panel and into the door panels, as well as the foot wells, sills and under the seats.

A unique instrument cluster with large, reconfigurable LCD displays offers a multitude of vehicle information readouts, including fuel cell information and vehicle performance. Like the CTS, the Provoq has a prominent center stack that houses the audio and climate systems, as well as a navigation system that rises out of the top of the instrument panel. Also like the CTS, there is an integrated hard drive that stores navigation maps, thousands of songs and more.

Between the front bucket seats is a large center console with a fully enclosed storage compartment that is home to ports for USB-connected devices and other electronics. The console also has a cell phone holder with built-in Bluetooth and inductive charging. The compact shifting mechanism on the console uses shift-by-wire technology to engage the gears, resulting in more storage space within the console.

A variety of recycled and recyclable materials were used, as well. Highlights include:

• The headliner is wrapped in a fully recyclable soy-based material
• The carpet is made of recycled polyester and jute
• Leather used to cover the seats and instrumental panel is free of harmful chemicals
• Xorel material used on the door panels and instrument panel; treated to perform as a carbon-fiber-type material
• Chrome trim made with less-harmful materials

The earth-friendly interior components blend seamlessly with the more conventional materials inside the Provoq, enhancing the vehicle’s integrated, customer-focused environment. The same goes for the cargo area, which features an auxiliary power outlet and a load floor that is level with the hatch opening.

"The integration of the features and technology is remarkable,” said Erdey. "If you didn’t know there was a hydrogen fuel cell stack under the hood, you’d never know it was anything but a roomy, functional crossover.”
