My wife purchased a 2014 ct200h in January of this year. It's not just suppose to be a luxury Prius, it is! Much like the Corolla/Vibe is the same car in Sedan and Hatch back forms. The Prius and CT200h share everything other than body paneling and interior. Engine, hybrid battery, transmission, suspension, brakes are all the same.
The CT200h has lower MPG's because the hatchback shape is less efficient than the sloppy back of the Prius.
An automatic Vibe is neck and neck 0-60MPH and 1/4 mile times. zeroto60times.com numbers back this up.
If you are looking for something a little faster with similar fuel economy (40ish) look at the hybrid Camry or Lexus ES hybrid.
