You didn’t think Porsche was done with the special-edition 997s, did you?
We thought that Porsche had pretty much squeezed everything it could get out of the current 911 (internally called 997), which is due to be replaced by the heavily redesigned and bigger 991 at the Frankfurt auto show this fall. But we were wrong: meet the 911 GT3 RS 4.0, a stripped-down track fugitive equipped with the largest engine ever installed in a series-production 911, a naturally aspirated 4.0-liter flat-six that reaches 500 hp at 8250 rpm. That’s up from 450 hp at 7900 rpm for the 911 GT3 RS with its 3.8-liter flat-six. The maximum torque of 339 lb-ft—up from 317—arrives at 5750 rpm.
