The savings aren't enough to justify the cost of the car vs any standard car out there, but at $.22 per mile it costs $22,000 in fuel alone to drive my truck 100,000 miles.
For the Tesla - $1000
Of course, I'm comparing it to a full size truck with a V8...
What if we compare it to a similar car:
Lotus Elise - 240HP
Cost - $64,890
MPG - 24avg
Cost per mile - $0.17
only if the price of 93 stays at $4.10 per gallon
Fuel cost @ 100k miles - $17,000
TCO @ 100k miles - $82,890 (including $1000 for oil changes)
Tesla Roadster - 248HP
Cost - $109,000
MPG - 135 (wtf?)
Cost per mile - $0.01
Fuel cost @ 100k miles - $1000
TCO @ 100k miles - $110,000
The Tesla costs $27,110 more to operate over 100,000 miles than a Lotus Exige SC. In the grand scheme of things, that's not
that bad. This is the first production run and the prices are expected to drop once new models are introduced. Once you get over the sticker price, the cost of keeping it running is quite nice actually
For someone who puts 10,000 miles on their car a year - not a good choice. For someone who puts on 30,000 miles or better per year, it's definitely something to look into.
