  1. Chevy Volt Engineering and Design
    So we all know that the Volt has a Thermal Management System (TMS) for the battery to keep it in the optimal operating range. The TMS requires cooling (I live in Florida, cold climates would obviously be different) provided by the A/C. So After driving for some amount of time, the battery...
  2. Suggestions for GM - Chevy Volt
    Hey all! I'm currently an advertising student at Temple University and am doing my senior project on developing a campaign for the Chevy volt. I was wondering if you all could take this 1Q poll on the Volt...thanks! http://www.surveymonkey.com/s/BWF8DHC
  3. Suggestions for GM - Chevy Volt
    I thought Lithium batteries were about 100 W-hr/lb; which would make the Volt battery about 160 lbs. So why is the curb weight 3780 lbs? That's 300 lbs more than my Mercury Sable Station Wagon! One suggestion is to minimize the gas engine. Driving at 70 MPH takes about 25 kW (33 HP)...
  4. Generation 1 Volt (2011-2015)
    I went over to the myvolt.com site and found the Efficiency and Mileage buttons to be disabled. I wanted to check out the car's charge history and download it. What's up?

    The EPA has their efficiency ratings for the 2012 Volt up on FuelEconomy.gov, and it's showing a highway "Electricity Only" efficiency of 93 MPGe -- up from 90 MPGe for MY2011. This bumps up the combined city/hwy efficiency from 93 MPGe to 94 MPGe. http://www.fueleconomy.gov/feg/phevsbs.shtml...
  6. General Motors and General Automotive Topics
    GM is hoping to increase the efficiency of their combustion engine cars by recapturing some of the emitted heat. The post below shows how they are thinking of doing this. Short answer: shape memory materials that change shape at different temperatures...
  7. Suggestions for GM - Chevy Volt
    First of all, hello everybody! I am a mechanical engineer and I have lots of interest in EVs and hybrid technology. So, after reading and watching quite a lot on the Chevy Volt's design and operation modes, I couldn't help asking myself has this design, with all its innovation, missed the whole...

    "Volt owners drove an average of 800 miles between fill-ups since the Volt launched in December, and in March they averaged 1,000 miles," said Cristi Landy, Volt marketing director. "When the majority of miles driven are electrically, gas usage decreases significantly."...
  9. Generation 1 Volt (2011-2015)
    Any Volt owners out there able click on the Efficiency icon on the myvolt.com website? When I hover over it or the Mileage icon with the mouse, all I get is a “COMING SOON” bubble. Anyone knows when this information will be available on the website. It appears to be available on the OnStar...

    Quote from: Living With the Chevy Volt: the First 1300 Miles ( http://gm-volt.com/2010/11/29/living-with-the-chevy-volt-the-first-1300-miles/ ) Someone help me with this? This does not seem to pass my smell test. Seems like the driver in this mode would use more resources … wouldn’t the...
  11. Nissan
    So, the Nissan Leaf is using a single 80kW AC synchronous electric motor to provide drive power. Though more simple than the Volt, I suspect that this drive arrangement would be less efficient at higher speeds due to the fixed, single-speed ratio. Do we have any details about the energy...
