"Is the number one concern then, reliability, durability of the engine 
If we at the lingering issues, we have a number of categories. First was fuel economy, second was reliability, third emissions, fourth oil consumption. When we decided to do [the rotary]
over, I told the engineering department "you have to fix these issues!" Because, if not, we are not going to have a compelling story. 

Fuel economy has been improved. The engine itself is 30% lighter. The rotors are lighter, the eccentric shaft, all that." 

This is a bit scary. What did they do to the eccentric shaft to make it lighter? PL

"On the emissions and fuel economy, the car as a whole is lighter. The
way they redesigned the rotary engine, they put the exhaust ports and intake ports on the side housings. Before there was an overlap in the chambers, so you would get unburnt
hydrocarbons. This did a number of things. One, didn't let the engine run lean, decreasing fuel economy, and second the emissions were bad because of the hydrocarbons. They did a
number of other things in terms of the seals around the block and rotors, some neat things... 
So I think they did a good job of constructing this engine. It is lighter, revs faster, has more power without turbos. -- "
