Frank Klegon talks about types of hybrids

Frank Klegon, Executive VP,Chrysler powertrains and engines, talks about the different types of hybrid engines, and how they related to Chrysler.   The two types of hybrids discussed are Two-mode-hybrids, and Mild-hybrids.  Two-mode allows for the use of electric or internal combustion at low speeds, and internal combustion at higher speeds/heavier loads. Mild-hybrids have larger starter motors, which allows the  engine to be shut off when the car is stopped, coasting, or braking, and then restarting quickly.

Mild Hybrid
Within the next few years, Chrysler will offer a mild-hybrid powertrain in a Chrysler Group vehicle.

Mild-hybrid vehicles provide many of the benefit’s of hybrid technology, with less of the cost/weight penalty that is incurred by installing a full hybrid drivetrain. Mild hybrids allow the vehicles engine to be turned off at stops. Regenerative braking stores energy that would normally be lost. Accessories can continue to run on electrical power while the engine is off. An electric motor assist results in significant fuel efficiency gains.

Two-mode HybridChrysler Group announced today that it’s two-mode hybrid program will expand beyond the Chrysler Aspen Hybrid and Dodge Durango Hybrid, which debuts next year.

Chrysler Groups two-mode hybrid system leapfrogs current technology by addressing inefficiencies that exist in high-speed driving with traditional hybrid technology. The result will be a 25-percent improvement in fuel efficiency overall ” and nearly 40 percent in the city ” in the Chrysler Aspen Hybrid and Dodge Durango Hybrid.

The new Chrysler Aspen and Dodge Durango Hybrid vehicles can be powered either by the electric motor or by the 5.7-liter HEMI® V-8 engine with MDS ” or a combination of the two. When full power is needed, the system automatically adjusts for passing, driving steep grades or hauling a trailer. The result is trend-setting hybrid technology that provides superior fuel economy, performance and load-carrying capability.
