Karma’s new GS-6 is offered in Standard, Luxury, and Sport models, all sharing the sleek exterior design of the company’s upmarket Revero GT. The three GS-6 variants are powered by a transversely mounted, 400 kW twin-motor rear drive module (RDM) energized by a 28 kWh lithium-ion battery pack that delivers 61 miles of battery-electric range. The combination, which produces 536 horsepower and 550 lb-ft of peak torque, comes with an EPA rating of 70 combined city/highway MPGe. Range increases to 330 miles with additional electricity from a 1.5-liter, turbocharged three-cylinder gas engine spinning a 170 kW generator.

The driver can select one of three modes that control how the motor is powered: Stealth mode uses the battery pack only; Sustain mode accesses the generator to create electricity to power the car; Sport mode uses both the batteries and the generator to supply power directly to the motors.

The drive system’s Sport mode is available in all GS-6 versions, not just the Sport model. The line-topping Sport model is differentiated from the other GS-6 versions by its 22-inch wheels (21s are standard on the others), red Brembo brake calipers, and torque vectoring from the RDM.

The GS-6’s leather interior is available in a choice of five colors and accent trim that range from carbon fiber to reclaimed wood from forests burned by California wildfires. The car’s Human-Machine Interface enables driver control of features including steering feel, accelerator pedal aggressiveness, and its Advanced Driver Assistance System (ADAS). Controls in the haptic steering wheel give the driver command of the sound system and phone, driving modes, adaptive cruise control, and a three-mode regenerative brake system. The center touchscreen contains controls for the HVAC system, heated and ventilated seats, audio, and lighting. Also controlled through the center screen is the GS-6’s Track Mode, which provides data ranging from lap times and g-forces to energy use and even tire pressure and temperature.

The ADAS aboard the GS-6 has a long list of assistance and safety features including adaptive cruise control with stop and go, lane-keep assist, automatic emergency braking, blind-spot monitoring/rear cross-traffic alert, forward collision warning, and parking distance monitoring. Onboard cameras provide a 360-degree view around the Karma. Apple Car Play and Android Auto capability are built into the GS-6, and it can receive over-the-air updates for remote diagnostics and software upgrades.

While it sells vehicles globally, Karma's operations are in Southern California with headquarters in Irvine and a production facility in Moreno Valley.

It’s interesting to chart the growing sales of hybrids and other clean vehicles today. What’s really enlightening, though, is to understand how these vehicles are being used and what their implications are for our driving future.

That’s where cutting-edge demonstration projects like Austin’s Pecan Street bring great value to urban and transportation planners, by providing a real-life example of how far we can take sustainable, low-, or no-carbon transportation and daily living with currently available technology.

Austin’s Pecan Street, Inc, the country's first non-profit research and development consortia focused on energy, wireless, and consumer electronics technology, recently joined with GM subsidiary OnStar to collect and analyze real-world energy consumption through driving and charging data patterns. Thanks to the GM/OnStar partnership, the Pecan Street project now includes the Chevy Volt for gaining critical real-life usage data for the use and charging of extended-range electric vehicles. Chevrolet made 100 Volts available for priority purchase to residents participating in the project last September.

Among the grid-relieving solutions developed by OnStar are charging with renewable energy, energy demand response, time-of-use-rates, and home energy management. The partnership with Pecan Street is enabling OnStar to test these smart grid services in realistic, everyday scenarios. Additional partner companies like Sony, Whirlpool, Oncor, and Intel are also providing residents with smart grid and clean energy products and services, such as photovoltaic panels for generating power, batteries to store energy, and smart grid tools to help make everything work in unison.

The final goal of the project is to help consumers make the best possible use of energy for daily life, and specifically for charging their plug-in hybrids and other electric vehicles. The hope is that research resulting from the project will help speed up the innovation cycle around smart grid and consumer electronics technology. This is important since electric vehicles add significantly to a home’s energy profile. Understanding how, and when, consumers use their electric vehicles and keep them charged is critical information.
