The Tesla Roadster—a hotshot car that runs on batteries.

Roadster

A week ago, I for a spin in the fastest, most fun car ever ridden inand includes the Aston Martin I to buy once. I was so excited, in fact, I decided to take a few days to down before writing it. Well, my waiting period is I’m thinking rationally, and still unbelievably stoked the Tesla.

I’ve always at how long the antique internal-combustion has survived. By 2006 standards, my power plant is a noisy, poison-spewing monster with way too moving parts. One spin in a made me realize that the gas might finally be on its last not because electric cars help wean us from oil and save us from global

Rather, the Tesla Roadster is a demo that proves cars now outperform their counterparts in comfort, convenience, best of all, speed.

motors differ from engines in lots of ways, but the curve is the most startling. In a car a gas engine, you press the accelerator, the rotates faster, and its torque rises to reach a somewhat-flat At that point, the car accelerates as the engine spins ever Eventually, the torque starts to off, and it’s time to the engine’s speed back the sweet spot, shift up to the gear, and start over.

Why do cars have so many To make sure the engine is in its maximum torque zone at about any speed. Spin it too though, and the engine stalls.

The in a gas engine comes from compressing and exploding a mix of fuel and air in one after another. In an electric, by motion is generated from the magnetic force created electric current runs wire coils inside the As a result, the torque curve on at full strength as soon as an motor begins to spin—its torque is at 0 RPM—and fades in a constant curve as it spins You don’t need to idle it to it running. You can see the difference between and gasoline torque curves in chart.

Get in a Prius and press the pedal, and feel it—instantaneous and silent, and steady.

What’s the upshot of all A hotshot driver who masters the of coordinating gas pedal, clutch and shift lever can take a 500 Corvette from standstill to 60 per hour in four seconds. I do mean you—could do the same in a Tesla.

Just stomp your down.

It’s one thing to this stuff in theory. another to experience it on Highway That’s where I hitched a with Martin Eberhard, the inventor.

Eberhard got behind the of a Tesla prototype and put the pedal to the I was flabbergasted. In the passenger seat, I was in an all-powerful force that me forward with a perfectly push.

I’ve been this fast before in European cars, always a mix of excitement and omigod we’re all to die . But as Eberhard zoomed around trucks and shot into openings, I never once with worry. I thought miss the sexy rumble of a engine, but I didn’t. In the silence I less distracted, more on the road.


No lurching, no racket, no hesitation—this is why buy Beemers to commute.

Eberhard is unsung breed of Silicon genius: the hardware engineer. I paths with him briefly 15 ago when we both worked for a that made computer It was obvious he was the company’s secret

The first batch of cars is assembled in England by Lotus, a sports-carmaker.

Eberhard says traditional have failed with for two reasons. First, they them as penalty boxes for do-gooders and gas-mileage-obsessed penny-pinchers. they just don’t batteries. The Tesla’s giant battery pack gives it the to hit 60 in four seconds, to run 250 miles a recharge, and to charge rapidly at its charging base (a one-hour will take you 80 miles; it a 3.5-hour charge to go 250 miles). You can plug into a wall at a roadside stop in a pinch.

Tesla is working on a model  aimed at competing BMW’s 5-series, a $50,000 to sedan with room for adults and a full-sized trunk. It may license the electric-motor tech to carmakers—an all-electric Prius out of the question.
