I already suspected as much based on my Fiat 500 (which also has a tiny turbo engine) that P&G doesn't work for a car like this.

But today I had a bit of time to kill so I thought I'd prove it.

I have a ~4mile test loop, it circles a lake so it's pretty flat and being a loop cancels out any wind assistance, not that there was any. There are three sets of traffic lights on the loop but I pretty much caught one red per loop so they roughly cancelled out.

Weather was in the 35*C range, auto A/C on, target speed 74km or 46MPH. Accelerating at 80% load.

First loop, constant speed SGII reported 5.35l/100km or 44MPG, also recorded the highest AVG speed.

Next up was P&G using DFCO, that netted 6.9 or 34MPG

Finally, P&G using neutral coast, that netted 6.4 or 37MPG, however at the lowest AVG speed.

The clear winner is the steady state cruise, you'd want to run the test a number of times before deciding between DFCO and neutral, I literally can't feel the difference when I put the clutch in and a closed eye passenger couldn't either. The van uses a relatively large amount of fuel when in neutral as it idles at around 1.3-1.7L/hr.

EOC isn't possible with the push button start.

At a steady 74km/h I was averaging 3.8l/100 or 62 MPG US

I changed out the factory fill oil at 3260km, ideally I'd have done it a bit sooner, but you know...

When I removed the undertray, I was able to have a bit of a poke around under there.

First thing I spotted was the in line electric water pump to cool the turbo after shut down (the actual water pump is a variable geometry design). This explains why I can hear a whine much like the Prius inverter pump after shut down:



It seems that this would be a good idea for anyone with a turbo doing much engine off stuff. My Fiat has factory S/S and no such pump!

Electro-Hydraulic Power steer pump. This explains why the steering works with the engine off, but it feels like hydraulic steering:



Could be useful for swaps into bigger vehicles where the Toyota MR2 pump might be insufficient. I didn't look into how complex the wiring is, but probably not as simple as the Toyota three wire hook up.

That electric water pump cooling the turbos after shut-off is one of the best ideas I've seen implemented yet.
