BorgWarner R2S two-stage turbo boosts performance of new top-end Ford 2.0L diesel

Green Car Congress

One compact KP35 high-pressure turbocharger generates boost pressure at low exhaust gas flow rates for rapid acceleration at low engine speeds without delay or turbo lag. As engine speed increases, the exhaust gas stream is split, and the larger K04 low-pressure turbocharger works in series with the KP35 high-pressure turbocharger.
