BorgWarner's Regulated Two-Stage (R2S®) Turbocharging Technology
Helps Boost Performance and Fuel Efficiency for
the 2.2-Liter Diesel Mercedes S 250 CDI BlueEFFICIENCY
Auburn Hills, Michigan, January 17, 2012 - BorgWarner's
award-winning regulated two- stage (R2S®)
turbocharging technology boosts performance while helping
improve fuel efficiency and lower emissions for the first
four-cylinder engine in the history of the Mercedes S-Class.
The 2.2-liter diesel S 250 CDI BlueEFFICIENCY is the first
car in the luxury segment to consume less than 6 liters of
fuel per 100 km.
"BorgWarner's highly efficient turbocharging technology meets
the highest demands in performance, fuel economy and
emissions," said Frederic Lissalde, President and General
Manager, BorgWarner Turbo Systems Passenger Car Products. "We
are pleased to collaborate with Mercedes-Benz to set new
benchmarks for powerful downsized diesel engines in the
luxury segment without compromising performance."
To develop a state-of-the-art engine featuring low-end
torque, responsiveness, high output and low emissions,
Mercedes-Benz chose BorgWarner's regulated two-stage
turbocharging system for the new four-cylinder diesel engine.
The compact R2S system consists of one small KP39
high-pressure exhaust gas turbocharger and one large K04
low-pressure exhaust gas turbocharger. The high-pressure
turbine is first driven by the exhaust gas, revolving at up
to 215,000 rpm. BorgWarner engineers integrated a bypass into
the high-pressure turbine casting which allows the turbines
to be controlled based on engine speed and generate optimum
boost pressure over the entire engine speed range with
excellent torque characteristics. The R2S turbocharging
technology fulfills the requirements of state-of-the-art
engine concepts, allowing maximum exhaust gas recirculation
rates even under full load conditions while significantly
reducing NOx
emissions.

While still offering excellent dynamics, the engine provides
its maximum torque from just
1,600 rpm in the S 250 CDI and achieves a fuel consumption
rating of only 5.7 liters per
100 kilometers (41 mpg). This equates to CO2
emissions of 149 g/km (240 grams/mile).
