I've always marveled at how long the antique internal-combustion engine has survived. By 2006 standards, my car's power plant is a noisy, heat-blasting, poison-spewing monster with way too many moving parts. One spin in a Tesla made me realize that the gas engine might finally be on its last legs—and not because electric cars will help wean us from Saudi oil and save us from global warming. Rather, the Tesla Roadster is a rolling demo that proves electric cars now outperform their gas-guzzling counterparts in comfort, convenience, and, best of all, speed.Check out the tesla website. Here are some pertinent technical points:
Eberhard says traditional carmakers have failed with electrics for two reasons. First, they market them as "penalty boxes" for environmental do-gooders and gas-mileage-obsessed penny-pinchers. Second, they just don't understand batteries. The Tesla's giant lithium-ion battery pack gives it the power to hit 60 in four seconds, to run 250 miles without a recharge, and to charge rapidly at its home charging base (a one-hour charge will take you 80 miles; it takes a 3.5-hour charge to go 250 miles). You can even plug into a wall socket at a roadside stop in a pinch. That makes the Roadster a viable commuter car and weekend day-tripper. The company claims energy costs as low as a penny per mile.
When you build a car that’s electric, you start with one built-in advantage: Electric cars just don’t have to be as complex mechanically as the car you’re probably driving now. Sophisticated electronics and software take the place of the pounds and pounds of machinery required to introduce a spark and ignite the fuel that powers an internal combustion engine.Way, way cool!!!
Most of the subsystems in the Tesla Roadster are completely electronic and under direct software control. But unlike all other cars, these systems are not a hodge-podge of independent systems — instead, they are designed as an integrated system, the way complex network and computer systems are designed today.
