Great News! They are oddly silent about the CO2 emissions, however.

http://media.fiskerautomotive.com/global/en-us/Media/PressRelease.aspx?mediaid=571&title=fisker-karma-proves-83-km516-mile-electric-range-in-tuv-testsAnaheim, California USA – November 2, 2011: The Fisker Karma has
achieved 83 km/51.6 miles running in silence on electric-only mode during
independent fuel efficiency tests carried out by Europe’s regulatory body,
the Technischer Ueberwachungs Verein (TUV) today (“De” according
Annex 9 of ECE R 101).
The TUV have carried out the most thorough tests yet of the Karma’s realworld urban performance. This is an independent process that measures
every element of the Fisker Karma luxury plug-in hybrid’s performance.
“We are delighted that the TUV has confirmed that most owners will
achieve a 50 mile range running purely on electric during their daily
commute,” said Fisker Automotive CEO and co-founder Henrik Fisker.
Perhaps those are not done / not released yet?Fabulist said:Great News! They are oddly silent about the CO2 emissions, however.
There is also missing data. Was the speed of this test 5 MPH or 50 MPH. I suspect that an EV is like any other vehicle where energy consumption goes up in a non-linear manner with speed. That is, it takes more energy to go one mile at a higher velocity than a lower velocity. Additionally if the speed is near light speed there is time dilation to take into account.ct-fiskerbuzz said:Perhaps those are not done / not released yet?Fabulist said:Great News!

A little Google sleuthing yielded a description of the test from Annex 9 of the ECE R101 document referred to in the Fisker press release. You can read all 101 pages here:JSPONSLER said:There is also missing data. Was the speed of this test 5 MPH or 50 MPH.

Here's the operative sections from Annex 9, starting on Page 94:JSPONSLER said:There is also missing data. Was the speed of this test 5 MPH or 50 MPH. I suspect that an EV is like any other vehicle where energy consumption goes up in a non-linear manner with speed.

I really like the fact that the procedure specifically permits bathroom breaks (4.2.2.4).4.1.1.3. For externally chargeable hybrid electric vehicle (OVC HEV) with an operating mode switch as defined in Annex 8:
4.1.1.3.1. If there is not a pure electric position, the manufacturer shall provide the means for performing the measurement with the vehicle running in pure electric operating state.
4.1.1.3.2. The procedure shall start with the discharge of the electrical energy/power storage device of the vehicle while driving with the switch in pure electric position (on the test track, on a chassis dynamometer, etc.) at a steady speed of 70 per cent ± 5 per cent of the maximum thirty minutes speed of the vehicle.
4.1.1.3.3. Stopping the discharge occurs:
- when the vehicle is not able to run at 65 per cent of the maximum thirty minutes speed; or
- when an indication to stop the vehicle is given to the driver by the standard onboard instrumentation, or
- after covering the distance of 100 km
[Then the vehicle is charged overnight followed by:]
4.2.2. For hybrid electric vehicle
4.2.2.1. The applicable test sequence and accompanying gear shift prescription, as defined in paragraph 1.4. of Annex 8, is applied on a chassis dynamometer adjusted as described in appendix 2, 3, and 4 of Annex 4 of Regulation No. 83, until the end of the test criteria is reached.
4.2.2.2. The end of the test criteria is reached when the vehicle is not able to meet the target curve up to 50 km/h, or when an indication from the standard on-board instrumentation is given to the driver to stop the vehicle or when the fuel consuming engine starts up. Then the vehicle shall be slowed down to 5 km/h by releasing the accelerator pedal, without touching the brake pedal and then stopped by braking.
4.2.2.3. At a speed over 50 km/ h, when the vehicle does not reach the required acceleration or speed of the test cycle, the accelerator pedal shall remain fully depressed until the reference curve has been reached again.
4.2.2.4. To respect human needs, up to three interruptions are permitted between test sequences, of no more than 15 minutes in total.
4.2.2.5. At the end, the measure De of the covered distance in km is the electric range of the hybrid electric vehicle. It shall be rounded to the nearest whole number
