With the introduction of its S400 BlueHYBRID occurring this summer, Mercedes is set to become the first automaker to offer extremely efficient lithium-ion battery technology in a mass production passenger automobile. Significantly, Mercedes bathes the notoriously hot-running lithium-ion cells in chilled air from the S400's A/C system, ensuring their safety and longevity for an estimated 10 years or 600,000 charging cycles.
ADAC, the German Automobile Association and Europe's largest car club, awarded Mercedes its Yellow Angel award for the Innovation & Environment category for its use of lithium ion battery technology in the S400 BlueHYBRID. Currently, Daimler AG holds 25 patents for their development of lithium-ion battery technology, all of which contributed to the reality of lithium-ion technology in their premiere luxury sedan.
Combining lithium-ion battery technology, engine stop/start functionality for its 3.5-liter V-6, and regenerative braking, the S400 BlueHYBRID promises to be the most fuel-efficient gasoline engined hybrid in its segment as well as offering the lowest CO2 output given its class and power output. Fuel economy should ring in at about 30 mpg, with C02 emissions at 186 grams per kilometer.
