    My favorite ELR review so far

    Well-researched, insightful, critical where necessary, and right on target. If I had to write an ELR review for a newspaper, this is very close to what I would have submitted. (I would have added my complaint about the 0-60 in 7.8 seconds being a sham since that only occurs after the battery has been depleted.) Kudos to the New York Times.

    I agree, very good review, and the description of the generator operation was good, several reviews lead one to believe the "engine" provides propulsion when the batteries are depleted, when in fact the ELR is always propelled by the "motor".

    There is also a connect indirect from the gas engine to the driveline (as in the Volt); this was done for efficiency at certain conditions.

    While the below is taken from a Volt article, these phases are shared with the ELR: (see mode four)

    Mode one is electric drive, with power to move the vehicle coming from the electric traction motor. The vehicle is in full electric mode, and this is the mode it would operate in most of the time in the city. In mode two, the electric generator motor is added into the power output through the planetary gearset. Although the vehicle can operate full range on only one electric motor, adding the second one improves efficiency at highway speeds. Again, the vehicle is operating as an electric vehicle but this mode is used more often for highway driving.

    Mode three is an extended drive-range mode. When the battery pack becomes depleted, the gas engine starts up and runs the electric generator motor to recharge the battery pack. The vehicle is propelled by the electric traction motor only, with power coming from the battery pack as the gas engine recharges it.

    Finally, mode four engages clutches in the transmission so that the gas engine can help the electric traction motor propel the car, while also using the electric generator motor to produce additional power to be stored in the battery pack.
