Has anyone ever objected to additional horsepower? Didn't think so.
The BMW M550i xDrive is no slouch with its potent 4.4-liter twin-turbo N63 V8 engine producing 455 horsepower and 480 lb-ft of torque. Thanks to all-wheel drive grip, the car takes just 3.9 seconds to hit 60 mph, making us question why anyone actually "needs" to buy an M5 anymore. Clearly, BMW isn't asking the same question because BMW Blog reports that the M550i will soon gain even more power.
Inside sources at Munich tell BMW Blog that the M550i will be updated with a new version of the N63 V8 found in the recently revealed 8 Series Coupe. The only announced version of the 8 Series in the US is the M850i xDrive, which produces 523 hp and 553 lb-ft of torque from its twin-turbo V8. This engine, producing approximately the same amount of power and torque, will reportedly find its way into the M550i for the 2020 model year. If this rumor turns out to be true, this would be an increase of 68 hp and 73 lb-ft of torque.
The 530 hp version of the N63 should eventually find its way into all '50i' badged BMW models, including the X5, X6, and upcoming X7. The X5 is currently being sold as a non-M Performance xDrive50i, which will likely be replaced towards the end of 2019.
