Top Electric Cars - Part II

• Fisker Karma



The Fisker Karma is a sporty looking, car that has the power to back up its looks. The Fisker comes with a Q-drive Technology. It has an innovative gas/ electric motor combination. In a way it is a hybrid, the electric motors (2) are the only mechanical drive to the wheels. The gas motor is mated with a generator that feed the batteries only if the batteries need to be recharged. The batteries have a range of 50 or so miles then the gas motor/generator comes on giving the Fisker a range of 300 miles, At a 100 miles per gallon U.S. The Fisker has a top end speed of 125 miles per hour, zero to 60 in 5.8 sec.. The twin electric motors produce 200+ Horse Power at 960 ft-lbf torque. The model shown at the car show was a convertible, with a folding hard top.

• Nissan Leaf




The Nissan Leaf

The EV-11 (Leaf) uses an all electric drive train, the motor is 110 Horse Power, has a lithium-ion Battery pack. The Leaf has a range of 100 miles in City driving. The Leaf also has Navigation system, remote control from your cell phone and remote monitoring from your cell phone through Nissan secure data center. The expected price of the Leaf, depending on options, will be between $25,000 to $33,000.

Nissan Leaf will employ an advanced IT system. Connected to a global data center, the system provides support, information, and entertainment for drivers 24 hours a day.

The dash-mounted monitor displays the Leaf's remaining power, in addition to showing a selection of nearby charging stations.

User’s mobile phones can be used to turn on air-conditioning, the heater and re-set charging functions even when the vehicle is powered down. An on-board remote-controlled timer can also be pre-programmed to recharge batteries.

• Chevy Volt


The Chevy Volt is an electric hybrid car. It has an electric drive only,  has the range of 40 miles on a full battery charge. When the batteries are discharged, the gas motor drives a generator to supply the electric motor the power needed to keep going, this gives the volt a range of many hundreds of miles. The first year’s volume, by GM’s own calculations, is 10 000 units.

 The idea behind the Volt is wonderful. The car doesn’t have to trade off power between motor and engine from second to second according to some exquisitely complicated mechanism or scheme. Instead, the Volt makes electricity the main course. Today’s hybrids put the motor and engine in parallel so that they juggle their power contributions to the wheels according to many different parameters, including speed, battery charge, and the load on the engine. But the Volt links the power plants in series. That way the motor powers the wheels, and the engine merely engages, when needed, to recharge the vehicle’s enormous lithium-ion battery. How enormous? If you drive no more than 65 kilometers (about 40 miles) and have an electric socket handy at both ends of your commute, you won’t burn a drop of gasoline.

One problem I see in the near future is that inexpensive algae fuel will be available and will require no change in car engine design. The algae product will be mixed in with the fuel we pump now, and will eventually replace most of the oil imported from the Middle East.
