I test drove both and really leaning towards the leaf. I love the way it drives, interior, and the fact I don't have to visit the gas station every 2-3 days.
Here's some math:
You drive 140*5=700 miles per week for work. The Prime can only do about 25 miles a day all-electric if you charge at home, so we'll basically ignore that.
Prius Prime: $27,750
55 mpg, 11.4 gallon tank = 620 miles of range
700 miles / 55 mpg * 2.60 = $33/week in gas
- Fill ups will be around once a week
Leaf SL+: $36,400 after optimal incentives
3.7 miles/kWh, 60 kWh battery = 220 miles of range
Electricity at home: $0.08/kWh (corrected to your post)
700 miles / 3.7 miles/kWh * $0.13/kWh = $15/week in electricity at home
- Fill ups at home every night, and if you miss one you can't make it to work
- The Leaf comes out ahead on weekly cost, but costs almost $9k more (or about 600 weeks (11 years!) worth of fuel savings) in the best-case.
- You can probably write off weekly fuel costs from both vehicles as a work-related expense, but the same doesn't apply for the Leaf battery. $36,400 is after $8k in subsidies from the $45k list price.
- The drivetrain on the Leaf is never going to give you issues, but the battery will almost certainly degrade to around 80% of original capacity within 6-8 years while the Prime will at most lose 5-10 mpg over that timespan or even improve due to wearing-in
- At around 3 full charges a week, you'll put ~150 cycles on your Leaf battery per year. Batteries tend to hit 80% capacity after about 700 cycles, giving you about 5 years of life in the pack before your range drops to 170 miles.
- The SL+ battery won't be down to 30% capacity after five years - maybe 80%. But a replacement pack from Nissan will be around $15k.
- Roadtrips longer than 200 miles will take about 60-70% longer in the Leaf than they would in a Prius due to the time required for charging.
- Other posters have mentioned possible maintenance issues with the Prime, but I've ignored them as they're not likely to cost more than $5k over a 10-year span.
The Leaf is a great car, and fun to drive, but on a purely financial basis I'd go for the Prime.
In case you really want to spend $37,000, you could get a used 2014 Tesla...
