Suzuki reveals hybrid concept

American Suzuki Motor Corporation (ASMC) has unveiled a gas-electric concept variant of its Kizashi sedan at the 2011 New York Auto Show. The Japanese OEM says the four-door hatchback further illustrates its global eco-mobility goals. “We are continuing to study the virtues of the gas-electric technology found in the Kizashi EcoCharge Concept,” said Steve Younan, director of automotive marketing and product planning for American Suzuki Motor Corporation.

“Our basic concept was to attain substantial gains in fuel economy without the traditional sacrifices in drivability required with today’s mid-size hybrid sedans. The proof of our concept is that the Kizashi EcoCharge has the capability to deliver a 25% fuel economy gain in real-world driving through an electric charge to the powertrain system while still retaining the production Kizashi’s dynamic handling and braking advantages that make it a standout category performer.”

The Kizashi EcoCharge Concept derives power from a 2-liter inline-four gasoline engine, working in tandem with an advanced electric propulsion system, which consists of a liquid-cooled 15kW motor/generator unit tied to a 115-volt air-cooled lithium-ion battery. Suzuki says that this combination optimizes fuel economy and delivers an electric power boost during acceleration for a more spirited driving experience.

To help maximize efficiency, the Kizashi EcoCharge Concept also makes use of numerous fuel-conserving technologies, including regenerative braking, automatic engine shut-off when the car comes to a stop, fuel cut-off during deceleration events and low-rolling resistance tires. Power management is provided via an advanced six-speed automatic transmission designed for smooth operation and a seamless flow of power when called upon by the driver.
