The 2020 BMW 5 Series is about to get a lot more horsepower.
With a 0-60 mph time of just 3.9 seconds, the BMW M550i xDrive is so quick, upgrading to the M5 seems pointless - especially when the M550i starts at $74,450 while the M5 is whopping $102,700. We know the M5 is a blisteringly fast car with a 0-60 time of under three seconds but it just doesn't seem like a necessary upgrade for $28,000. The M550i achieves its speed using a 4.4-liter twin-turbo N63 V8 producing 455 horsepower and 480 lb-ft of torque, but rumors indicate its gap with the 600 hp M5 could be closing even more.
The rumors predicted that the M550i would receive the newer version of the N63 engine from the 8 Series, producing 523 hp and 553 lb-ft of torque. Now CarBuzz can confirm, the rumors were true.
BMW of Europe has released an extensive list of updates for the 2020 model year, including a massive power upgrade to the M550i, which now produces identical power and torque figures as the M850i.
We reached out to BMW USA who told CarBuzz, "the US version of the M550i xDrive will have the same N63 engine starting with July production (2020 Model Year) in the US."
This means if you buy your M550i in the second half of 2019, it will have 523 hp instead of 455.
It is still a little early to predict how the extra 68 hp will impact performance, but since the M850i xDrive takes just 3.6 seconds to sprint to 60 mph, we would not be surprised if the 5 Series matched this time. BMW has also been underrating the output of its engines recently and after driving the M850i, we would not be shocked if the 0-60 time was closer to the low three-second range. We have also been told to expect a more potent version of the X7, which also uses an older version of the N63 V8. So perhaps the X7 will be the next BMW model to benefit from 8 Series power.
