Zagato Alfa TZ3 will be based on the Dodge Viper.
That would change its dimensions significantly as the two-seater, rear-wheel drive supercar will grow wider, longer and heavier too than the 850 kg (1874 lbs) TZ3 Corsa. Heavier by a good 600 kg (1320 lbs).
The new TZ3 may also get the Viper's 612 PS (450 kW / 604 bhp) 8.4 liter V10 engine as opposed to the 4.2 liter V8 with 420 PS (309 kW / 414 bhp) of the initial design study vehicle.
And all that extra power would do is make up for all the extra weight.
The TZ3 will be presented at Pebble Beach in August with production set to begin in 2012.
