Underneath the rather generic supercar body lies the beating heart of the beast: an 8.3-liter V10, purportedly sourced from the Dodge Viper, and tuned to deliver 780 horsepower. That's said to be good enough to propel the carbon, kevlar and titanium supercar to 100 km/h (62 mph) in a don't-blink-or-you'll-miss-it 2.9 seconds. The engine is mated to a choice of seven-speed paddle-shifter, automatic or gated manual transmission, 19" wheels coated in ultra-low-profile rubber grip the road at all fours, and the engine is even designed to burn straight alcohol if so desired. Production will be limited to 99 examples, each available at a price of around $670,000. Given GTA's racing background, a competition version is also expected to be in the works, so stay tuned.
