Let me begin: 1. 30-mile electric range without reduced cargo space. 2. More powerful motors. 0-60 time under 9 seconds in electric or hybrid operation. 3. 5th seat. Doesn't matter if the headroom in the middle seat is insufficient for an adult. It's extremely rare for 5 adults to be in one car. 4. Support for Android Auto and Apple CarPlay. 5. Bump in price of no more than $1000. Bonus: Adoption the GR design that's apparently available in Japan. The new Dynamic Force engine found in the Corolla hatch. That's it! With these changes, the Prime would be the perfect no-compromise green vehicle that is also somewhat fun, and easy to love and brag about. Sales would go through the roof.
