Interesting article. Having seen all these cars recently and just leasing a FFE last week, there is no comparison. The FFE is like a luxury car inside and out. I would never, NEVER drive the Spark due to its cheap interior and dorky looks. Everyone remarks how nice the exterior and interior styling is on my FFE. And C&D mentions the slow charger like its not important. My FFE charges in 2.5 hours and often less on a 30 Amp Level 2. You can use it more often by charging during the day, making it way more useful. The FFE is heavier - but its also BIGGER and more useful. I can fit all 3 of my kids in there comfortably. The Spark is a 4 seater, and it very small inside.
And yes, the Turbo Cord is 20 Amps and really throws of the charging time difference between the Spark and FFE. Charge time is a huge factor in my purchase. My office is considering installing Level 2 chargers. so it will make the car even more useful during the day and still be able to get home.
Spark Charge Time: 7 hours on Turbocord AND even a Level 2 charger
FFE Charge Time: 6 hours on Turbocord, but 3.5 hours on Level 2 charger. C&D makes no mention of this little fact.
No way the Spark should have won in the real world.
EDIT: The Spark is only available in 2 states. The FFE is widely available, including my state of New Jersey. Selling a car in only 2 states should be a factor as well.
