BMW M3/M4 Redline Might Reach 8,000 RPM
Wanting really bad to find out just where the redline of the new cars will be (since they will be turbocharged) some forum members started analyzing audio tracks of the cars being tested on circuits.
Using the Doppler effect and specialized software they came to the conclusion that the new S55 engine might actually have the redline somewhere from the 7,700 RPM mark up to 8,300 RPM.
If this is confirmed, then it would be great news for all the BMW community. At the moment, the most powerful unit from BMW's line-up of engines is the S63B44TU one that develops 560 HP and 680 Nm (501 lb-ft) of torque and has a 7,200 RPM redline.
As you probably already know, turbocharged engines usually reach lower RPMs than naturally aspirated ones. Thus, having an engine with an 8,000 RPM redline in the M3 and M4 would be quite a performance, as the German company already confirmed the new cars will be dropping naturally aspirated units.
Let's hope the estimations of the Bimmerpost members will come true and those two cars will be legendary!
