The rise of Tesla is probably the most fascinating enterprise story of the twenty first century, and for me probably the most fascinating half has at all times been the early days, when a motley crew of multitalented engineer/entrepreneurs hatched a daring technique to problem probably the most highly effective of industries. I devoted plenty of house to Tesla’s early days in my history of the company, however now Mark Vaughn has gone even additional again, and shared some beforehand unheard tales from Tesla’s prehistory in an article for Autoweek.
In 2003, Vaughn was testing automobiles on the California Speedway, and in the future he bought a name from Tom Gage, CEO of the pioneering EV agency AC Propulsion, asking if he may track-test a brand new automotive that he and his crew was engaged on. This turned out to be the tzero, which was named for t0, the mathematical image for a place to begin in time. Little did anybody on the observe that day understand that this brilliant yellow two-seat roadster could be the start line of a far-reaching technological transition.
Or was it? Vaughn takes us even additional again in time, to somewhat package automotive made in Brighton, Michigan by an engineer named Dave Piontek. The Sportech, which was powered by a bike engine, had a curb weight of 1,100 kilos and as much as 250 hp, giving it “an absurd power-to-weight ratio of 4.4 kilos per hp.”
“It was a hell of plenty of enjoyable,” Piontek, now retired and driving a motor house round Florida, informed Vaughn. “I accomplished the unique automotive in 1989. I painted it in my storage, I actually did in all probability 90% of the work myself. That automotive hauled ass!”
Piontek finally constructed seven automobiles, one among which made its solution to Dr. John Fagan, a professor {of electrical} engineering and laptop science on the College of Oklahoma, round 1997.
Paul Carosa, who was AC Propulsion’s VP of Engineering, informed me that Fagan was the one who originated the thought to construct the tzero. “They did their very own model of this little electrical sports activities automotive that was based mostly on a car known as the Piontek. [AC Propulsion founder] Alan Cocconi and I have been intrigued by the thought, and we purchased one among these automobiles from Piontek.”
Fagan put one among AC Propulsion’s electrical drivetrains into his Piontek Sportech, and the end result was no golf cart. “It was a badass drive,” Fagan informed Mark Vaughn. “That factor had about three quarters the torque of a Tesla right now.”
Fagan tried to get a producer to construct the automotive, however was unsuccessful. Nevertheless, his efforts impressed the mad scientists at AC Propulsion to construct their very own electric-powered Sportech at their store in San Dimas, California. This was the primary tzero, and the remaining is historical past.

Nevertheless, historical past, a minimum of within the automotive and tech worlds, progresses by way of a sequence of many iterations. The unique tzero had 28 lead-acid batteries, which weighed 1,000 kilos and have been mounted within the car’s sides. It was a cramped, heavy automotive with a variety of solely 60 miles.
AC Propulsion’s second tzero prototype was powered by 6,800 laptop-style lithium-ion cells (cylindrical cells within the 18650 format). It was 700 kilos lighter than the unique model, and had a variety of about 300 miles. This was the automotive that Gage, Cocconi and firm introduced out to the California Speedway in 2003.
“It was missing inside facilities, match and end, and plenty of different issues {that a} mass-produced, modern-day automotive would have,” Mark Vaughn remembers. “It possible wouldn’t have handed any crash-test requirements anyplace on this planet, both, nevertheless it launched faster than nearly something made and was nimble and tossable and mainly felt like a race automotive, or a minimum of a really light-weight sports activities automotive. It wanted sorting within the suspension division; it was too simple to get to oversteer, and even after we performed round with camber and tire pressures, it nonetheless wanted some sorting. However that’s what engineers do, they usually finally figured it out.”
Round this time, Martin Eberhard, a profitable Silicon Valley entrepreneur who beloved quick automobiles however was additionally involved in regards to the setting, had simply gone by way of a divorce, and was seeking to purchase a sports activities automotive. He was already acquainted with Tom Gage, and he quickly grew to become intrigued by what was occurring at AC Propulsion. Eberhard needed to purchase a tzero, however the AC Propulsion crew had shifted their focus.
“We realized that we couldn’t proceed to make cash, not to mention meet crash take a look at requirements and the like [with the tzero] so we form of modified gears and began creating the eBox, an EV conversion based mostly on the Toyota Scion xB” Tom Gage informed me. They ended up constructing 25 models of the eBox, which was “a really sensible utilitarian car,” however Eberhard had his eye on greater issues, and he knew that practicality wasn’t the attribute that might get folks to alter their notion of EVs.
Now historical past actually shifted into overdrive. Eberhard, joined by Marc Tarpenning, JB Straubel, Ian Wright and Elon Musk, used the tzero as the premise for the revolutionary Tesla Roadster. For the remainder of the story, read Mark Vaughn’s Autoweek article (which incorporates some cool, never-before-seen photographs), then read my book. It’s an interesting story, full with conflicts, larger-than-life characters (not all of whom bear in mind occasions the identical approach), near-death experiences, tragedy and triumph, and it’s removed from over.
On the coronary heart of the story, after all, is a sequence of ever-evolving cars, and Tesla’s Plaid Model S is the most recent hyperlink in a lineage that goes all the way in which again to Dave Piontek’s storage in Brighton, Michigan.
