Q uantum Performance seems to be a big fan of the number 7 to be: The Australians worked on their first project for 7 years, the GP 700. A track tool with 710 hp and 700 kilograms. A power-to-weight ratio of more than 1 hp per kilo - so far only a few hyper sports cars have been able to do this ex works: Even the Koenigsegg One: 1 fails to meet the power-to-weight ratio specification of the Quantum project.

Stronger than a Koenigsegg One: 1

With its power, the GP 700 from Quantum should be able to accelerate to 100 km /h within 2.6 seconds. This puts the 710 PS Australian in the middle when using similarly designed vehicles as a comparison. The Ariel Atom V8 with 482 PS zooms to country road speed in 2.3 seconds, the KTM X-Bow R with 300 PS needs a seemingly eternal 3.9 seconds in a triple duel.

To the Porsche 918 To achieve acceleration at Spyder level, Quantum uses a reamed Honda engine. The 2.7 liter engine is pressurized by two compressors and develops 710 hp (700 bhp) at 7,800 rpm. The maximum torque is at 6,500 tours: namely 654 Nm. The engine is coupled to a sequential six-speed gearbox from the German manufacturer Holinger. A maximum of almost 200 miles per hour is possible - around 320 km /h.

Quantum GP 700 is made of Kevlar and aluminum

Even if the Quantum GP 700 looks quite compact in the photos, At 4.1 meters, it is almost as long as a VW Golf - anything but a mini-racer. But in contrast to the Golf, the Quantum Extremling weighs only about half as much. The reason for this is easy to find: The chassis and the structure of the GP 700 are made of Kevlar and aluminum - materials that have so far mainly been used in combination in space travel.

Speaking of space travel: required in contrast to the space shuttle the Quantum super sports car had a lot of downforce, not lift. Overall, the contact pressure should be 1.8 times the force of gravity. With the special Yokohama R-Spec tires, up to 2.5 G should be possible in fast corners. The space shuttle pilots might know what that feels like - they have to withstand up to 3.0 G at take-off.

Quantum GP 700 costs three times as much as an Ariel Atom

Like the NASA Apollo program, the Quantum GP 700 is quite expensive. For the 710 hp at 700Kilos are worth a good 700,000 US dollars (approx. 630,000 euros). An Ariel Atom V8 can be had for less than 190,000 euros. Actually already expensive, but in comparison it seems like a bargain. The KTM X-Bow R would be even cheaper, it costs around 80,000 euros, but in contrast to the Ariel Atom V8 and Quantum GP 700, it cannot offer a 1: 1 power-to-weight ratio and has little to do with Quantum's favorite number 7.
