[Video] Tuned 515hp BMW M550d xDrive 5 Series

Check out this BMW M550d that’s McChip-tuned and will make choosing between the M5 and this one difficult. In standard form, the BMW M550d has a quad-turbo 3.0 liter inline-six diesel that makes 400 hp and 560 lb-ft of torque. Imagine bumping these already fantastic numbers to 516 hp and 638 lb-ft? Well that’s what this McChip tune does. In this new video from AutoTopNL, we see a POV drive video of the tuned BMW M550d and it’s flipping fast. Although, it had to be limited to just 261 km/h (162 mph) due to winter tires being fitted to the car. Still, it gets to that top speed very quickly.
