Honda Insight review -- two years of mileage data
You can see the summer months still give the best performance by quite a bit. This can be attributed to needing to run the engine more in the winter to heat the cabin and the fact that the engine doesn't shut off at stops. Also, battery performance is degraded in colder temperatures. If I were buying a Nissan Leaf, I'd want to understand what a Wisconsin winter will do to the overall range as the Leaf has air cooled batteries like the Insight (albeit at a much higher capacity).
Overall, I'm still relatively pleased with the mileage numbers. The car is by no means fun to drive and I wouldn't recommend it for longer highway trips. But, it is an excellent city car and I haven't had a single issue with it.
One more year to go before the lease is up. I'll most likely be moving on to another car. I've driven the Chevrolet Volt and like the package. Since I drive mostly in the city, I'll benefit from being able to drive electric nearly 100% of the time. However, I like the flexibility of being able to drive longer distances and I think the gas generator is nice insurance against the reduced cold weather performance 100% electric cars will likely see in Wisconsin (at least in the short term).
