Testing the Long-Awaited Fisker Karma Plug-In Hybrid

• http://www.popsci.com, By John Voelcker

Then the recession, a switch in battery suppliers and other delays kept Fisker from shipping the first trickle of cars until late last year. This spring, we got one of the first test drives.

THE TEST

We drove two Karmas on two coasts, along winding roads in California and in stop-and-go Manhattan traffic. We covered more than 70 miles, in both all-electric Stealth mode and Sport mode, which blends engine and battery power for maximum acceleration.

THE RESULTS

Even in New York and Los Angeles, where exotic cars are a common sight, the Karma drew stares. In Sport mode, the Karma performs well, running from 0 to 60 in a brisk 6.3 seconds. But Fisker prioritized design over comfort and efficiency. The Karma has only slightly more interior room than a Ford Focus; the low roofline is largely to blame. At 5,300 pounds, the car is also heavy. As a result, the Karma is substantially less efficient than the Chevrolet Volt, which uses a similar plug-in powertrain. In all-electric mode, the Fisker’s 22-kilowatt-hour lithium-ion battery provides 32 miles of range. The Volt wrings an EPA-rated 35 miles from its much smaller 16-kilowatt-hour battery. Like the Volt, the Karma has a gas engine that kicks in once the battery is depleted—but then fuel economy drops to 20 mpg.

I would not want to be an investor in this boondoggle. Since when does design have to hamper efficiency? And how is it they "shipped a trickle" before the test drive? Wouldn't the test drive come first? They have violated the first two fundamentals needed make an EV sell, low drag & low weight. I want to know why Aptera failed to produce a car. The demand was there as the thousands of orders showed. It must have been regulations. Why else would the market fail to fill a desire? Does any one know the details?
