Last summer, Zagato unveiled its Alfa Romeo TZ3 Corsa at the Villa D'Este as a celebration of the 100th anniversary of Alfa's involvement in motorsports. The car is now entering limited production as the TZ3 Stradale.

The Corsa was billed and envisioned as a pure racing car, and the TZ3 Stradale is the street-going version--but it keeps that raw intensity, based on the Dodge Viper, which was itself a race car barely disguised in street trim. While German-language reports say the TZ3 Stradale is longer, wider, and heavier than its donor, Zagato has confirmed with us that it is in fact the same dimensions and actually lighter than the Viper, as it has a carbon fiber body.

Unlike the Corsa, which was intended to get its power from a 4.2-liter V-8 rated at 420 horsepower paired with a six-speed sequential gearbox, the Stradale is expected to keep the Viper's 8.4-liter V-10 and 600-horsepower output. That's double the displacement and nearly 40 percent more power--it's hard to argue with either, unless you're planning to commute with the car.

Not that it would be unsuitable for the task from a purely logistical standpoint: the TZ3's two-seat/long back coupe design adds a spark of praticality to the coupe form factor.
