Purchased As New
Delivered April 2012
$36,157 out the door in CA (1.79% for 72 months @ $530/mth) with $2500 federal tax credit and $1500 state rebate (credit and rebate not deducted from total price).
30 mile one way daily commute – per tank MPG range is from 51 to 68 MPG depending on number of electric recharges (EV miles are added to gas miles divided by gallons of gas).
Individual 30 mile commute with battery usage is high 60s/low 70s MPG with highest recorded 91 MPG during Friday return home where freeway traffic is slow and I can stay in EV mode on the freeway and totally deplete the battery (due to start/stop technology, using battery even in HV mode during low speeds/low power needs and regenerative breaking the Prius will give best MPG in slow rolling freeway traffic). Use EV (electric) mode on surface streets (work to freeway 4 miles and home to freeway is 2.5 miles) and switch to HV (hybrid) mode when on freeway at speed.
During long trip with no battery charges I get 52-54 MPG just on the gas engine in HV mode.
1. Purchased the Prius Plug In for better gas mileage and ability to get the car pool sticker (40K in CA).
2. Purchased the Prius Plug in rather than the Volt due to the mature/proven technology on the Prius (except for the new larger battery), ability to hold 5 persons with good room in the backseats and higher MPG in gas mode for long trips.
3. Battery charge is 3.1 KHW as seen from Charge Point station (there is no indication from car on total KWH charged to battery) into the 4.4 KWH battery (you don’t want to totally discharge or charge the battery to battery extend life). Battery range indication was consistently at 11 miles in May but is decreasing with June at 10.5, July and Aug 10.1 and Sept 9.8 miles at initial start up after charging. The indicated vs actual miles are fairly consistent but you can go further in EV mode at slower speeds. Since I switch between EV and HV modes I can’t get good number for actual EV miles to exhaustion range during normal driving so I’m doing range tests (two laps around “block” with right hand turns) 12.6 miles @ 36 MPH avg without AC or lights on.
4. The Prius operates in Hybrid or Electric Modes. Within each mode you can select the throttle response between economy, normal and Power. I operate in economy to maximize fuel economy. The car has increasing more pep when you go to normal and then Power. You can select between HV and EV modes but there are times the car will switch automatically between the two (e.g., EV mode – engine will start if you need heat, push hard on the gas (once the engine starts there is about 2 minute run time to warm up) or go over 65 MPG. In the HV mode the engine stops and uses battery at stop or low speed/load conditions). The driving experience is acceptable but not like 2002 Mercedes Benz (MB) C320 wagon which I commuted in previously (26 MPG average). The Prius is comfortable during long trip but not as comfortable as the MB.
5. At work there are four EV recharge stations. It was OK until the 5th EV showed up. As there are more EVs you can’t count on the recharge station being available and even when it is you need to be able to dedicate the delay in the trip to recharge.
6. The Prius gets 25 – 35 MPG during the initial 4-6 minutes of engine warm up. At $4.00 gas the cost to go 10 miles @ 50 MPG is $0.80 and @ 25 MPG is $1.60. To fully charge the battery (3.1 KWH = 10 miles) @ $0.08 per KWH is $0.25, @ $0.13 per KWH is $0.40, @ $0.30 per KWH is $0.93.
7. I will be moving to the E-9A time of use electric rates (one meter for home and EV), recharging the Prius both at home and work and fully exhausting the battery during each leg of the commute. The rate between midnight and 7 AM is $0.05 KWH so there will be even more savings. Since the charging rate is 8 amps at 120V and the Prius needs only 3 hrs to fully charge I will not get a 240V home charging station.
