Straight from one of the best channels for car enthusiasts on Youtube, we’re looking today at a rather interesting BMW M4, one that claims to be putting out a whopping 620 HP. That’s quite a figure, considering the S55 engine under the hood is running on stock internals and is only a 3-liter mill, making this a car with a 210 HP/liter ratio. Sure, nowadays, with forced induction in the picture, that kind of ratio can be achieved by a number of manufacturers/tuners but it’s still quite impressive, no matter how you look at it.
The car has been tuned by the people from Mosselman and was quite heavily modified as well. Details about what went on under the hood are not shared but, in order to achieve this kind of horsepower some hardware changes were most likely needed. From a new intake, to a new exhaust, ECU tune and bigger turbos, a lot of work would have to be done to make sure the rods don’t pop through the hood when reaching maximum velocity.
Speaking of which, this car is also seemingly no longer restricted to 250 km/h (155 mph) as it manages to stretch its legs up to a whopping 300 km/h (186 mph). The thing is, it doesn’t look all that fast doing it. For a car this light and with so much power going to the rear axle, we expected the acceleration to be a bit more brutal. Then again, some excuses can be found in the power levels themselves, if you will.
The driver might’ve used caution so as to not end up spinning on a limitless Autobahn, possibly causing a massive pile-up. That sounds like a possibility but the video doesn’t exactly seem to show that happening as it appears like the pedal was to the metal at all times. Nevertheless, this car definitely sounds interesting and we’d love to know more about it.
