How well does this work in practice?
You're waiting at the lights in winter, heater/radio/lights/wipers on and the engine turns off presumably everything else carries on working. What about power steering/brakes. And stop/start crawling in traffic? Must give the starter a workout.
The starter is completley different compaired to a "conventional" engine. Some of the more trick systems can control the specific movement of the piston.
Personally, with 90k miles but I'd be well happy of 55-ish mpg. Turbos probably well past it's best, fuel system too; \I'd bet there's all kinds of wear and tear in there that, collectively, bring the figure down.
