I've got news for you guys. My source is reputable as he is one of the head engineers on the nextgen NSX project.
Back in December of 2005, after all NSX production ceased, Honda engineers began experimenting with the FMEx concept. FMEx is an acronym for the Front Mounted Exhaust experimental. The idea was to move the exhaust to the front of the car to reap a number of benefits. First, they discovered that the exhaust could be self-tuning creating the perfect amount of backpressure while the the car was in motion. Next, it was discovered that by the noise cancelling effects of the oncoming wind that they could use higher performing, typically louder exhausts without an increasing noise inside out outside of the car. They used a mechanical silencer when the car was idling.
This design also kept the car running cooler. Honda engineers were able to eliminate the need for water cooling by designing a special aluminum radiator that used the actual fuel from the fuel tank to cool the engine. When the fuel was fed back into the direct injection system, they found that the additional heat was beneficial in vaporizing the gasoline for combustion creating a more efficient and powerful engine. The FMEx project changed the way Honda would build cars. It reduced the weight of the car, number of components, and increased power and efficiency.
Fast forward to the middle of last year and what all of this has to do with the next generation NSX and how Honda pulled off the ultimate coup. Honda rolled out the NSX successor for testing at the track in the pictures you see, dressed up almost like an S2000. You guys are all screaming we want an MR car and Honda did listen to you. Don't you remember they asked for your feedback and to meet at
this event here? That mule you see on the track IS infact MR! You see the exhaust and how it's mounted on the back? Wrong, that is the front of the car! The car was running around Nurburgring in reverse the whole time and nobody even knew.
