MyVVI: An Adventure In Data

I love cars, and I love data. About six months ago I had an idea that combined those two passions, and I’d like to share the result of that idea with you.

I was thinking about how people make decisions on what car to buy on one or more of the following three factors: performance, economy and aesthetic appeal. Aesthetic appeal is completely subjective; I might love the look of a Nissan GT-R (I do), and yet my girlfriend will despise it (she does) – but it’s impossible to argue the remarkable acceleration and power of that car, because both are measured scientifically.

Depending on whether you’re interested in vehicle performance, or vehicle economy, you’ll consider the following metrics when looking for a new car:

  1. Power Output (Performance)
  2. Torque (Performance)
  3. Acceleration (Performance)
  4. Fuel Economy (Economy)
  5. Price (Economy)

I decided to explore a way to lump performance and economy into one index that takes all these factors into account and allows buyers to benchmark similar vehicles by a single number.

MyVVI was the result of that thinking. The very good-looking public site is the excellent work of the team at Yellow Llama, but the really interesting stuff lies in how we spliced the data in the back end. Being able to search all sedans between R350 000 and R500 000 (as an example) and get a list of cars ranked by a single number was profoundly interesting. Comparing brands along the same lines was even more interesting.

I’ve been working on collating the data in the form of a report, and would like to share that data with you. Take a look at it and let me know if the information is interesting and or appealing at all. Your comments and feedback would be most welcome!

    Why have I only discovered this now! As geeky as this sounds, I have just found my reading for tonight :D Thanks for the report :D The major spanner though is comparing these numbers with cars available in the second hand markets..!
