Thoughtful interior

The interior environment of the Volt was designed to appeal to an urban dweller who desires a smart, daily-use vehicle, according to Wade Bryant, design director, GM Design.

“On the interior of the Volt, you’ll find technologies, materials and an environment that enable the car to help make life simpler for a person who’s environmentally conscious and leads a city-centered lifestyle,” said Bryant. “It’s ergonomically correct, provides connectivity to the world, and demonstrates smart responsibility through the use of lightweight, recyclable materials.” Two such examples are the instrument panel topper and steering wheel made with GE Plastics.

Bryant said the interior environment of the four-passenger Volt is defined by a host of current or near-term technologies and materials combined with the ingenious use of ambient light. “It’s definitely based in reality. All the things you see on the interior are within reach in the next few years.”

According to Bryant, the interior team and the exterior designers worked closely together to make the Volt look like one vehicle. Two examples of their collaboration are the dual beltline and the door hinge that’s visible outside of the car. “We designed this as one element that comes inside the door and becomes the interior pull handle,” said Bryant. “It’s all about integration, refinement and thoughtfulness.”

Super Imaging instrument cluster

Super Imaging is an innovative, dual-mode technology display that provides two visual levels of vehicle information to the driver in the instrument cluster. It is a design innovation developed to provide a primary interface between the driver and the vehicle’s key feature: the next-generation, electrically driven propulsion system.

“The dual-mode instrument cluster was developed to highlight the car’s plug-in capability,” said Bryant. “The powertrain technology is the key feature, so we wanted to make sure the interior communicated that, and the driver would have a sophisticated, fun and useful interaction with the electric-drive system.”

The first level of information – configured similarly to a conventional instrument cluster – provides traditional data in the form of analog, three-dimensional (3D) LED displays, including three gauges for fuel level, speedometer, odometer, battery level and the transmission “PRNDL” indicator. The second level of information – a transparent screen positioned in front of the 3D LED displays – delivers color, animated data related to the Volt’s advanced propulsion system with a holographic-like appearance.

Super Imaging works by using invisible, fluorescent inks that are printed on the transparent screen. When illuminated by an ultraviolet (UV) laser projector located behind the instrument cluster (from the driver’s perspective), the inks become excited, and provide four-color illumination and animation.

Foam/fabric surfaces

Compression-molded foam with a textile-patterned surface layer is applied on the entire lower instrument panel, lower door trim panels and rear quarter trim areas. The material enables soft, tactile, low-gloss surfaces throughout the interior cabin that appear hand-crafted and specifically tailored to the car.

This material, used in some of the latest luggage designs, enables zippered access to traditional storage areas such as the glove box, doors, etc. The material is very inexpensive, wears well and enables flexibility in design.

Composite panels

Molded GE plastic panels provide thin, structural interior surfaces that can be cantilevered in space. The material is applied on the upper instrument panel, seat backs, center console sides and door inserts.

Light, strong, affordable and recyclable, the panels are sheathed in reconstructed scrap leather to achieve a soft, hand-crafted surface.

Use of ambient light

The aspect of light – from outside and within the vehicle – is played throughout the interior environment. Highlights include a transparent upper roof that provides large quantities of natural light and is enhanced with thinner pillars and rail sections; Gelcore® LED indirect lighting around the roof periphery that illuminates during evening hour entry/egress and can be seen from outside the vehicle; LED functional storage lighting that passes through transparent zippers and provides ambient light during evening hours; and conductive ink controls situated on the interior surface of the glass roof that provide touch access to lights, OnStar buttons and more.

“All the storage areas are lighted internally, and the light escapes through the clear zippers, so you’ll always be able to find your storage at night,” Bryant said. “It all adds a nice little ambient effect, and the illumination will be color-keyed to the instrumentation lighting color. It’s functional and cool, and when you open it, light from the interior storage area spills out.

“A big enabler is the transparent upper roof. It provides the Volt with more natural light than most other vehicles. It’s very distinctive and appealing.”
