Exhaust specialist IND Distribution got its hands on a F10 BMW M5, a stock 2013 model and, before thinking about playing with its tech bits and pieces, it took the car to the dyno, as you can see in the video above, which comes from M5post. The result? a pretty interesting one...
The M5 was recorded at 527 WHP (wheel horsepower) and since the usual power loss between the crank and the wheels for this kind of car is estimated at 15 percent, this means that the 4.4-liter twin-turbo V8 under the hood is not churning out 560 hp as BMW claims, but 620 hp. IND Distribution also placed the car on a scale, where it exceeded BMW’s official specs by a figure that can be neglected.
All this makes quite a lot of sense, as this BMW scheme has been previously talked about. It seems that the Bavarian carmaker’s engines actually deliver more power than the official specs show. Want a proof? Check out the standing start acceleration times for virtually every model in the range, then compare it to cars that come with a similar power/weight official ratio and a close technical setup and you’ll see that the Bimmers always take the lead. This could only happen if... their engines were actually more powerful.
What can we say? We really can’t be upset by this (in fact we’re thrilled), since it makes BMWs accelerate faster and especially if we add up the thing that they’re also rather frugal machines, for their segments, of course, thanks to the use of Efficient Dynamics technology. But we'd like to know the truth...
