Just back from a shopping trip, 23 km round trip. I tried driving as economically as possible: at the start the expected range remaining was 550 km. At the end, this figure had increased to 560 km. I found at low throttle openings, upshifts happened at around 2100 rpm (redline is 7000). When coasting the instantaneous fuel consumption readout showed 0.0 l/100 km, indicating that all cylinders were shut down, receiving no fuel and with the intake and exhaust valves closed. Interestingly I was still travelling faster than some other vehicles.
