Yesterday, at the 37th International Vienna Motor Symposium, Porsche unveiled a new twin-turbocharged V8 engine that will power the future Panamera and Cayenne. This new twin-turbocharged V8 will displace 4.0 liters and replace the current, and aging, 4.8 liter V8 that Porsche uses in the current-generation Panamera and Cayenne. The new engine will develop 549 hp and 567 lb-ft of torque, which is 21 hp more than the 4.8 liter it replaces, but makes the same amount of torque.
This new Porsche V8 is actually built upon the same engine architecture as the Audi 3.0 liter twin-turbocharged V6 powering the upcoming Audi S4 and will be the entry-level engine option for the upcoming Porsche Panamera. We already knew that Audi and Porsche were going to be developing V8 engines together, but we hadn’t heard anything about them in awhile. Now we know exactly what the two brands were planning.
The new engine, while only being slightly more powerful, is 30 percent more efficient, features cylinder-deactivation and is optimized for hybrid applications moving forward. Plus, it likely has much higher power potential than the old 4.8 it replaces, as Audi’s 4.0 TFSI engine is capable of far more power than 549 hp.
But don’t expect this engine to stay within the Porsche family, as it will likely migrate over to Audis as well, in cars like the A8 and Q7, as it shares Audi’s architecture as well. It’s also possible to make its way across to Volkswagen as well, in the upcoming Touareg, and possibly even to Bentley and Lamborghini, in the Bentayga and Urus, respectively.
This engine spells good news for both Porsche and Audi, as the two companies working together will help lower costs of manufacturing these new V8-powered cars. It’s also not the only project the two companies could be working on together. Audi is rumored to be developing a new Audi R6 mid-engine sports car, based on the Porsche 718 Boxster/Cayman platform, but will use an Audi V6. It seems as if the VW Group wants to have a bit more product sharing between the two companies, which could actually help in the future.
