The highly anticipated 2013 BMW M5 sports sedan is packing a punch to compete with the likes of Audi A5 and 2012 Mercedes-Benz CLS 63 AMG. In stock form, the sedan is rated at 570 horsepower and 502 pound-feet of torque from its twin-turbocharged V8 engine. But like many auto manufacturers’ specs, these performance numbers most of the time are not accurately reported due to marketing purposes. That’s why we have tuners out there who are putting these cars to the test, the dyno test that is.
The latest dyno test on the new 2013 BMW M5 sedan was run by PP Performance on a MAHA LPS 3000 dyno, and the performance numbers spitted out from this machine tell us a different story in real world performance. As you can see from the published chart below, the engine power from the 2013 BMW M5 sedan is about 542 horsepower with its corrected power at 562 horsepower (converted from bhp). But the real number at work is the horsepower at the wheels, which is 435 horsepower. And for its torque, it is a bit higher than the original spec, which is actually 532 lb-ft at 4745 rpm.
From the results, the dyno test shows us that the 2013 BMW M5 sedan was over reported on its horsepower output and under reported its torque. So what this all tells us? For one thing, horsepower is a much more important marketing factor than torque. But luckily, we got tuners.
