| I've been driving my hybrid(compact estate) for over 7 years now and there's no noticeable change in fuel economy. That being said, both the figures mentioned are to me a little bit optimistic. I don't know about Teslas, but my fuel economy presents itself like this(figures are in litres per 100km): -City driving: ~5 + ~100ml to bring the engine to working temperature. Checks out to 7 on a 7km drive and falling with distance. -Highway, so maintaining real 120-140km/h (speed limit around here), 6.3-6.5. Absolute worst was 7.8 during a snowless -20°C night. -Backroads doing 70-90km/h, average trip speed 50km/h, and here is where I think hybrids shine - 4.0-4.2. -Hypermiling record: 3.7 as I was steadily rolling at 20-30km/h to a highway onramp a few kilometres away. Overall fuel economy is nice, but what I like about this car the most is the ease of manoeuvring on the parking lot and very little vibration when the engine is running. |
