Last week, in preparation for a pending clean-car challenge called the Michelin Challenge Bibendum, next Tuesday to Thursday in Sonoma, Mr. Cocconi was again ready to put the Tzero through its paces. With suspension and traction bugs ironed out, the Tzero ran the 0-60 test that yielded 3.7 seconds. It was also ready for a drive along the stunning Glendora Mountain road in the Angeles National Forest. With ample opportunity to run in the real world, the car was a wonder to behold. Because the car recharges its batteries when the throttle is released — slowing sharply as energy is recaptured — it can be driven hard using only the accelerator pedal. Also, if the car detects a turn with more than half a G-force, it eases the rear-wheel regenerative braking to prevent slides. After a driver has had a few minutes to get used to the system, there comes a wonderful sense of limitless, fluid power as the car quietly wails, dodges, thrusts and parries on the mountain road.
"That's unique with an electric," Mr. Cocconi said. "Whether you accelerate or decelerate, you're always in the right gear." He said that no traditional stick shift could do that.
In between the beautiful vistas and the twisting road, it was fascinating to catch glimpses of the ammeter, the gauge that shows the power being consumed. While it goes into negative territory on uphill acceleration, it flies the other way on downhills, charging the batteries. Mr. Cocconi said that because of the up-and-down nature of mountain roads, and relatively slow speeds, this is where the car is most efficient. Still, he said, he drove it 250 miles last week on the freeway, and the car's computer indicated it could have gone at least another 40.
At the end of a hard drive, including five scorching zero-to-60 runs, the car had traveled 57 miles and used only 9,900 of the 50,000 watt-hours in its batteries, costing less than the price of two gallons of gasoline. "These batteries," Mr. Cocconi said, "they're really pretty magical."
