However, for our purpose here, the key takeaway is that this system effectively minimized turbo lag. In Paul Frere’s renowned book, “The Porsche 911 Story,” there is a fascinating explanation of the intricate plumbing system employed in the Porsche 959. This clever sequential turbocharging system allowed for optimal performance across the rev range, delivering a truly exhilarating driving experience. However, once the engine surpassed the 4000 rpm mark, the exhaust gases from the left-hand cylinder were redirected to activate its corresponding turbocharger. What made the setup even more fascinating was the sequential operation of the turbos.Īt engine speeds below 4000 rpm, the right-hand-side turbocharger was energized by exhaust gases from all six cylinders. Equipped with two turbochargers, the engine generated an impressive output of 450 horsepower and 370 lb-ft of torque (likely an underrated figure). Powering this remarkable machine was a 2.85-liter flat-six engine, drawing inspiration from Porsche’s dominant 956 and 962 prototypes. The entire experience was utterly surreal, largely due to the unparalleled driving dynamics of the Porsche 959. What made this experience even more unique was the fact that I had the freedom to embark on this adventure without any supervision. This extraordinary vehicle was graciously lent to me by the Porsche Museum, and its caretakers entrusted me with the keys for a thrilling drive along the roads surrounding Sonoma Raceway. However, as time passed, this technology has become scarce, with Bugatti being the only remaining brand that continues to utilize it.ĭuring one of the most remarkable and exhilarating moments of my career, I had the incredible opportunity to drive a Porsche 959. During the golden era of turbocharging, several automakers including Porsche, Mazda, Subaru, and Toyota embraced the concept of twin sequential turbos in their cars.
