The RENESIS engine in the RX8 is the new improved model that was launched with the facelift. The gas seal lubrication system has been changed from a mechanical type to a electromagnetic type, and there is now one additional nozzle for a total of 3 now. This improves lubrication performance, which extends rotor seal life and fuel efficiency.
A peak horsepower of 212 horsepower (lower than the manual version which revs higher for more power) is achieved at 7,500rpm while peak torque is 211Nm of torque at 5,500rpm, which puts the car’s power figures rather close to the Civic Type R’s 225 PS and 215Nm.
As you know, the engine is a high revving one, but you should only put such strain on the engine after it has properly warmed up. Much like the BMW M3, the RX8 has a variable redline that prevents overrevving when the engine has not warmed up yet. Its redline varies and goes up in 3 stages according to engine conditions. I’ve never seen the actual car yet but apparently according to sources on the internet, the automatic version has both its redline and peak horsepower point capped to 7,500rpm, presumably because of the transmission?
