There are a number of minimalist cars on the market today around the world and perhaps the most famous of them all is the Ariel Atom. Another minimalist car has turned up from an Australian company called Quantum Performance Vehicles and it is called the Quantum GP700. The car has no roof; it doesn't even have a windshield. A version with a hard top is in the works.
The big feature of this little car is performance. The company shoehorned a 2.7L four-cylinder engine under the hood with a pair of superchargers. Power output is 700hp with 482 lb-ft of torque. All that power and torque goes to the ground via a six-speed Holinger sequential gearbox.
The car certainly looks the business too, it's sort of like a F1 car mashed up with that Arial Atom I mentioned before. The Quantum GP700 is festooned with aerodynamic bits to produce downforce and help handling.
The maker says that the car has enough aero to generate 1.9Gs of cornering force in a slow speed corner. If the car has enough room to reach 174mph, theoretically it would be able to drive upside down. That 700hp engine only has to push about 1500 pounds and it can reach 62mph in 2.6 seconds. Pricing and availability are unannounced at this time.
