Eh, the only thing I learned was the transmission's torque converter/clutch system. Which isn't terribly interesting.
I'd like to know more about how they actually achieved 40mpg. I'm not sure 14:1 compression, really good bearings, and a spiffy transmission add up to a 40mpg 2 liter.
I know it shuts the engine off at a stop and uses a compression cycle to start it again, which is awesome, but I'm not sure it's idle has anything to do with it's mpg rating.
Edit: Oh, yeah, the fuel thing sounds scary. I wouldn't be surprised if it was 3000psi. I'm assuming that's one pump at the tank, and one at the engine actually delivering the 3000psi. To safely deliver 3000psi of fuel all the way from the tank would probably go against their weight savings philosophy. Those would be some beefy lines.
Curly my friend in a civic.. she stops her engine on every light.. pushes 39mpg city.
I do this at some longer lights, and the outrageously long wait at the local Starbucks drive-thru. My problem is I have an OEM battery from 2007, and you know those starter motors on 4 cylinders that sound like they could start a giant V12? Mine is not one of them.
This is a 2008 Lancer, I average 27-29 a tank, which is up around it's highway rating, so I'm happy. I do wish I had a system that turned it off for me though.
I've considered trading in for a CX-5, but ever since buying the Lancer I promised myself I wouldn't buy another brand new car. But my main concern is I'd walk out with a 235hp AWD ralliart instead of a fuel saver. Even with the skyavtiv, I'd only be saving $16 a month in gas over my current DD, and adding around $290 a month, if I wanted to pay it off at the same time.
I only wish I had waited a couple years to get a new DD. There's a lot of 35mpg+ vehicles available now.
