Imo.. Don't see the point in all this comparisons aka cheaper car goes just as fast or faster .
Who cares if something goes faster or that its cheaper or more expensive etc etc?
Back on topic...There was also another test from car and driver.
2009 Porsche 911 Carrera vs. 2009 BMW M3 - Coupes/Comparison Test/Reviews/Car and Driver - Car And Driver
"The 911 has statistical appeal: It’s lighter than the M3 by 380 pounds without using Millennium Falcon materials, and it keeps the pace with an identical 4.1-second 0-to-60-mph sprint despite being down two cylinders, 385 cubic centimeters, and 69 horsepower. Midrange torque even feels stronger than that of the cammy, not-much-below-4000-rpm V-8 in the M3."
LOL! With this test the M3 is now the cheap (er) car that goes just as fast. The cycle continues..
