Porsche unveiled a new V-8 engine at the 37th Vienna Motor Symposium that will eventually power the range-topping variants of the upcoming second-generation Panamera and the next Cayenne SUV. In addition to powering the larger vehicles in Porsche’s lineup, the new V-8 will also be used by other Volkswagen Group brands including Audi and Bentley.
Featuring two twin-scroll turbochargers, the new 4.0-liter V-8 is rated at 550 hp and 568 lb-ft of torque (up from 520 hp and 516 lb-ft), which puts it just shy of the current 4.8-liter twin-turbo V-8 utilized in the 570-hp Porsche Panamera Turbo S. Despite its power, the new engine will also have lower CO2 emissions and improved fuel economy thanks to a cylinder deactivation feature that will cut consumption by 30 percent, according to Ward’s Auto.
The new Porsche-developed V-8 is rumored to be closely related to the turbocharged 3.0-liter V-6 designed by Audi for longitudinal applications. As a result, both engines are compatible with both the Porsche-developed MSB architecture and the Audi-developed MLB platform. This means it will be used for upcoming models such as the next Audi A8, Bentley Continental, and possibly the Lamborghini Urus SUV.
Last year, we reported that the second-generation Porsche Panamera will be the first vehicle to use the MSB platform, which will be shared with other Volkswagen Group premium brands including Bentley and Audi. Additionally, the car will also gain a new V-6 engine, which should slot below the more powerful V-8. In addition to the sedan, a wagon variant will be offered on the Panamera for the first time and it will also be available in the U.S.
