Well, here I am at 10,000km. As promised when I got the Volt I will keep the regular updates coming.
First, the stats because some of you just love that stuff. As those who are keeping tab may remember, I took the Volt in for the battery fix in early April and it hit 7000km on the odo as I drove onto the dealer's lot. The servicing was completely uneventful. They gave us a Cruze while the Volt was in and when we got the Volt back it was gassed up and fully charged. I'm sure glad it was nearly empty when I brought it in . But the car is different since the updates/upgrades; see below for commentary on that.
Obviously since the last update we've done an additional 3000+km. The weather in March was fabulous but April turned out to be ugly and cold with us happy to get into single digits! At the end of April we were still dealing with sub zero Celsius weather. Unbelievable. And so most of the improvement in fuel economy has been courtesy of the warm weather we've finally had in May.
Now onto the nitty gritty, the numbers:
- Average lifetime fuel economy: 1.3l/100km (181mpg)
- Latest 30 days average fuel economy: 0.6l/100km (392mpg)
- EV: 8659km
- Gas: 1905km
- Total: 10,064km
- Total fuel used: 130l
- Electric consumption: 22kWh/100km (35kWh/100 miles)
- Max all-electric range: 75km (47 miles)
- Current average range: 62km (39 miles)
- Max kWh used on single full charge: 10.1kWh
- Total months owned: 7
- Total cost electricity: $210 (estimate)
- Total cost gas: $112 (actual) (2 free tanks from GM excluded)
Some additional information that is now available from the Volt via GM's Volt site includes a running tally and daily details on charges, including start and end time, charge time and charge result (full/partial) and the kWh required to charge the car.
The following statistics are from April 24 - May 23rd.
- Max kWh required to charge from empty: 11.96
- Cost for said charge at my rates: $0.96 (@$0.08/kWh)
- Total for month: 310kWh
- Cost to charge Volt for entire month at my rates: $25.00
- Total charging time for month: 230 hours
A bit of arithmetic shows that we've gone 3064km using 15l of fuel for a fuel economy since the battery fix/software upgrade of 0.5l/100km or 470mpg!
Quite impressive, and now that the kids are both out of university for the summer both cars are getting quite a number of kilometres put on them.
Note that GM filled the car up at the beginning of April when we took it in for the battery fix. That means we've had 5 fill ups. I've done 3 and GM has provided 2. Fuel has cost me $112 for those 10,000km. Not bad :-). (Yeah, I realize GM paid for 2, had I paid for all 5 the cost would be $188.)
Since that April fill up we've put on 3064kms and only used 15 litres of fuel, with 15 litres remaining. That means our fuel economy has markedly improved with the warmer weather and now stands at 1.3l/100km (181mpg). Recall it was 1.6l/100km (147mpg) average when the winter hit, with me seeing 3l/100km (78mpg) in the most frigid weather. Now that it's warmer the weekly and monthly numbers are vastly different with this past week showing 0.5l/100km (470+mpg).
Further, our commutes have changed, meaning that the car is being driven utterly differently than it was a few months ago. It's now being driven on either 35km commutes or 60km commutes depending on whether my son and I go to our jobs in the west end or my wife and daughter head to the east end in the Volt. Because of these commutes and the fact the kids are out and about in the evenings I am considering getting a 240v charger.
As to reliability, the car has been utterly flawless. We are super impressed. GM has contacted us regularly to ensure we're happy with the car, which we are. And I'd happily have two Volts in the garage. My wife is already hinting that an ELR might be a perfect replacement once the kids move out into the real world in a few years. I don't think I can disagree .
As to the battery "fix", the most interesting results are that I am now always getting more than 60km to a charge in the warmer weather. In October when it was 22c+ I'd rarely break 60km though my son would regularly. Now, I get 62 - 65 all the time and I still drive aggressively. My son hits 70+km regularly. And our commutes are 70% highway. I'm sure we'd do even better if we did mostly regional roads instead of highways.
Additionally, GM must have adjusted the software controlling the generator. Where I could easily discern that it was on before now I have to strain to hear it. In fact, this week when we drove more than 60km we couldn't hear the generator and thought it wasn't on, it is now that quiet. I have no idea what GM did in terms of quieting the generator but whatever they did is amazing. I can barely hear it unless I try. In the city it's nearly as quiet as it is when it's running on electrons. If this is an indication of the type of software upgrades GM will do in future, I can hardly wait for the next one!
Another interesting bit of news is that those LED bulbs I put in the house are paying off nicely. I'm saving $30 - 40/month. The Volt is costing us about $25/month. So, we're driving for free, other than the gas we need now and again. And, yeah, the kids still leave the lights on all the time, it's just that I can now see how often courtesy of the savings being registered on our bill. It's actually lower now than it was before we had the Volt, so the Volt's cost per month is lost in the savings. Excellent.
[B]edit: I had the wrong rates. I used 10 cents, but that's worst case. It's actually 8 cents since we do it mostly off peak.
