The Quantum GP700 is an 800hp hypercar built in a garage
The Quantum GP700 is a high-performance hypercar engineered by Jeff David in a backyard workshop in Victoria, Australia. Despite its humble origins, the vehicle boasts impressive specifications, including 800hp and advanced aerodynamics developed through unconventional testing methods.
Why it matters
This story highlights the potential for individual innovation in automotive engineering, challenging the dominance of large-scale commercial manufacturers.
I point to a graffiti-covered bus stop in a layby, signaling to stop for a quick photo. That’s the excuse, anyway. In truth, I need a moment to stand on solid ground. After riding shotgun with Jeff, my head feels like I’ve just been bench pressing 160kg with my neck. Then again, 1.2g under acceleration will do that.
The numbers behind the Quantum GP700 are impressive: 800hp, 748kg (wet), 0–160kph in 4.4sec. Top speed remains untested, though it’s geared for 310kph. FastestLaps.com shows a 1:25.60 lap time around Winton National Circuit—nearly 4sec faster than a Merc-AMG GT R Pro.
