Hi everyone, This is my first post on this thread, but I've been reading it intensely for the last week or so and learning a lot. I was wondering whether anyone has any knowledge - either as data or anecdote - about the Clarity PHEV's energy efficiency in the real world. I read the entire thread about all-electric range, but what I'm specifically asking about here is efficiency - I'm particularly curious about speed vs. miles/Kwh (in EV mode) and/or speed vs. mpg (in HV mode). As an example of what I'm talking about in data form: Wayne Gerdes over at cleanmpg.com compiles some really awesome speed vs. energy efficiency graphs on all kinds of cars. Here are just a few, in case people haven't seen these elsewhere: Hyundai Ioniq HEV Blue: http://www.cleanmpg.com/community/index.php?media/32774/ Hyundai Ioniq Electric: http://www.cleanmpg.com/community/index.php?media/32145/ Toyota Prius Prime vs. Toyota Prius II Eco: http://www.cleanmpg.com/community/index.php?threads/49683/page-13#post-423256 Honda Civic: http://www.cleanmpg.com/community/index.php?threads/49683/page-11#post-415457 The reason I'm asking this question is that I'm thinking about buying a PHEV but I live in an area with high electricity rates. I'm also considering the Prius Prime and Ioniq PHEV, but for a number of reasons, the Clarity PHEV is at the top of my list. And so I'm trying to get a handle on what to expect in terms of average mpg in HV mode and average miles/kWh in EV mode. For example, if the Clarity PHEV averages 3.5 mile/kWH while the Prius Prime averages 5.5 miles/kWH, then at 20 cents/kWh, and driving 15,000 EV miles a year, the Prius Prime costs roughly $300 less per year to drive or $3,000 less over 10 years. Plus, it's still not clear to me how accurate the Clarity PHEV's 40 mpg EPA highway rating is. The latest generation Civic is also EPA rated at 40 mpg highway, but this is a drastic under-rating: I'm currently driving the latest Gen Civic, and in the summer, I can easily average 50+ mpg on a whole tank if I do mostly highway miles. In fact, yesterday, in 35 degree weather, I did a 250 mile highway trip with a lot of steep elevation changes and just by keeping the car between 55 and 65 mph, I averaged 47 mpg. The Civic is a fuel efficiency monster on the highway if you drive it right, but I'm worried that, given the Clarity PHEV's 4,000 lb curb weight, it's perhaps not very efficient at 50-65 mph, either in HV or EV mode. Anyway, any info people could share on this would be much appreciated. Thanks.
