Quantum GP700 | One to 1 Hypercar

Overview

17 December 2019

0 to 100 Kph in 2.6 seconds and 1:1 power to weight. Yes, that’s insane!

In an open car this extreme acceleration is like nothing else and the adrenaline you feel is an intoxicating experience.

Billed as Australia’s first “hyper car”, in 2015 the GP700 was born out of a 10 year passionate journey of its creator, Jeff David. The GP700 was the engineering prototype and produced breathtaking performance in a road legal car. It maintained an easy to drive character building driver confidence. Gaining driver confidence on the road is crucial in providing a familiar environment for a non profession racing driver to be capable of stepping up to the challenge once releasing the GP700’s potential at a race track.

At a race track the GP700’s 1:1 power to weight ratio (60% better than a Bugatti Veyron SS) and 1G of down-force create an adrenaline-inducing experience like no other.

The car delivers impressive low speed drive-ability, relatively inexpensive servicing costs and extreme performance all in one package. The Quantum GP700 is truly Australian having been designed and built in Victoria. The engine, gearbox, bodywork and electronics were all produced in Melbourne. The designer wished to acknowledge the assistance of the following Victorian companies and Universities in the design and construction – Keetch3D, Motec, Autronic, Beninca Motors, Holinger Engineering, University of Melbourne Mechanical Engineering, RMIT Mechanical Engineering, Deakin University Mechanical Engineering, and Western Smash repairs.

In 2015 the GP700 design appeared to be sold to be manufactured and marketed overseas. There was publicity on the Web with suggested pricing but to set the record straight none of this ever happened and the pricing was purely hypothetical and not based on the current car. Now in December 2019, 5 years later, the GP700 prototype has evolved into an amazing drivers car. I have mold’s for the carbon body panels, chassis jigs, uprights, suspension jigs, brakes, steering rack and a spares set of Aerospace chassis tubes all available. Building one single customer GP700 is possible before I get too old…

The epitome of motoring harmony, inside and out

From the aerodynamic bodywork to the pure driver centric interior, the GP 700 was designed for pure drivability and streamlined functionality

A pure Interior that connects driver and vehicle

The interior of the GP700 is everything we believe a race car interior should be, simple, efficient, and pure, allowing you to focus on the drive.

Our custom carbon seats and 3″ harness seatbelts cosset you as you grip the GP700s custom carbon fibre steering wheel ready to unleash 700 BHP. The Motec C187 dash provides you with all the relevant information on the car and can be individually programmed. It records 100’s of sensors on the car and overlays the data with GPS mapping. This can be studied later to improve your driving and car setup. This sophisticated computer forms an integral part of the GP700’s predictive traction control system, sampling data and making seamless computations.
The GP700 suspension gives you a “planted to the road feeling” and the seating has been developed to provide comfort and control. The combination is inspiring, enabling confidence to push yourself a little bit further.

A bold exterior that breaks the mould

The exterior of the GP700 is the culmination of years of computer simulations and on track development. The result is unparalleled handling for a road legal car on the track and wonderful drive-ability when you’re cruising on the road.

The outer body works as one with the cooling systems of the car, channeling air into the primary intake and side pods to feed the engine. At full power the GP700 engine requires 28,000 litres of air a minute, about as much as a person will breath in over 2 days.

The GP700’s bodywork has been designed with a rising form that pushes air over the cockpit to encapsulate both driver and passenger in static air. The open cockpit and wind mitigating body design provide good visibility and surprising comfort to the driver for an open roadster.
The car’s exposed wheels and adjustable racing wings make it a beautiful sight to behold while a 100mm ride height make it an effective road car. Part open wheeler race car, part custom sports car, every aspect of the GP700 exudes power and performance.

A smart car that works with your driving style

Predictive Traction Control

Immense power must be unleashed with control.
700BHP in a rear wheel drive car, which weighs only 700KG is normally a traditionally a recipe for over steer, tail slides, spins, and tire smoke. The Quantum GP700 however uses our specially developed Predictive Traction Control (PTC) system to ensure the maximum possible power is transferred to the road in a way that keeps you in total control. Quantum’s smart traction system can anticipate and be adjusted to react to your driving style. By monitoring the car sensors and through constant calculations the PTC system gives you a higher level of control than most cars.
For those that just want to drive, the Quantum GP700 is an easy vehicle to get in and go. However, many drivers want a higher level of customisation, so we give our drivers full control over their Quantum’s settings. Drivers can adjust the vehicles power from 300 – 700 HP as well as control he amount of traction generated, from straight as an arrow to full out drift mode. We are currently developing an App that allows drivers to monitor the performance of their car as well as adjust settings and fine tune the vehicles performance.
Imminent Gear System

The Hollinger Engineering transmission developed specially for Quantum allows the GP700 to upshift in 0.02 seconds. Both up and down shifting can be placed in automatic, keeping the car in the power band and letting the driver focus on the perfect line. On the road the GP700 does away with power shifts and throttle blipping, replacing it with something more traditional and raw, a clutch pedal.

Custom Tuned for a breathtaking 700 bhp

Tech2

At the heart of the Quantum GP700 is a 700BHP version of our custom built, twin supercharged 2.7 litre, 4 cylinder engine. To achieve the GP700’s level of ultra performance extensive modifications to the engine were required.

Unlike the majority of forced injection engines, our twin superchargers run in series. This provides much higher pressure than a regular supercharger without the lag of a turbo charger, resulting in a smoother and more powerful boost. At peak power the GP700 engine uses 6 litres of fuel a minute and requires two fuel injectors per cylinder as well as two intercoolers, multiple radiators and oil coolers to ensure the engine always stays at optimum temperature.

The immense power of the GP700 is administered by the engine management and traction control systems, which provides optimum power at full throttle as well as reduced noise and fuel consumption during normal road use.

curves and intakes working as one

Much like a fighter jet, the GP700’s exterior body is a culmination of science and meticulous analysis. The car’s sleek body, dual element front wing, and under floor diffuser work in unison to generate over 12,000 N of down force at 280 KM/H keeping the GP700 firmly on the track. Due to it’s efficient body design and diffuser set up the car sticks to the road with higher down force yet no increased drag.

Both the front and rear wings are adjustable which allow the Quantum GP700 to be tuned to your preferences, ensuring the perfect drive on any circuit.

a Powerful backbone for superior stability

The chassis and suspension form the backbone of every car’s performance. The GP700 sports a tubular chassis design engineered from aerospace grade aluminium, carbon fibre and Kevlar fibres. Light weight yet firm, the chassis provides fantastic stability at high speeds and excellent drivability at low speed. Along with the on board computer and ability to track the cars performance, drivers have can adjust the car to reflect track conditions and improve their cornering technique, shaving off those precious seconds of their lap time.

a mechanical system adapted for supreme drivability

The GP700 is fitted with a custom independent push rod actuated suspension with front anti-roll bars. Each Quantum GP700 has its suspension individually tuned to it’s owners liking and is valved for optimum performance. The GP700’s unique suspension system gives the car phenomenal grip at high and low speeds, allowing it to corner at over 1.9G’s even at medium speeds of 130 KM/H. Our Position Displacement Suspension (PDS) system creates a new level of predictable and consistent grip, adding a higher purity to the GP700 experience.
