The 'engine' has been essentially the same by 2006 audi s4

We weren't so certain approximately this tank locomotive's qualifications for WEOTD class, not because it doesn't quantity up in the awesomeness division but because it's damn near impossible to statistic out whether those stickler Porsche engineers organize completely unmitigated-mass-of-paper redesigned the device continually (keeping only the general draft, mounting hardware, and the waste of time centers). If we permit that the pugilist six-banger from Stuttgart has been largely the unaffected steam engine with a constant cycle of upgrades, then its origin stretches all the way spinal to the early 1960s. We'll let tipster Jason think over in with his arguments after the jump...Says Jason: First conceived in 1961 for the T7 prototype, and later installed in a 911 in 1964, the little 2.0L flat six turned out a whooping 130 hp. Fast accelerative to 1998, and the last air-cooled 911 (turbo) was cranking out 400 hp. The race flat-6 motors in the 935 were cranking out in excess of 950hp with water-cooled heads.
