Qan­tum leaper

AS I ne­go­ti­ate the round­about on an ur­ban road, the hi-tech G-force read­out shows 1.38. My seat of the pants G-force me­ter reads ‘‘ bail out’’ of the Jaydee Quantum open-wheeler. Cre­ator Jeff David mir­rors my inane grin.

Why? Be­cause the car stops, goes and cor­ners like a for­mula racer yet it’s docile enough, if the driver uses the right foot lightly, to run to the shops.

A trawl of su­per­car stand­ings re­veals the Koenigsegg CCXR — Swedish-built and cost­ing about $4 mil­lion— is slower than the Jaydee ve­hi­cle in the 0-100km/h sprint and also off the pace in lat­eral and brak­ing grip and roll-on ac­cel­er­a­tion.

David plans to sell the Quantum from $250,000 (topof-the range, about $400,000).

Stan­dard is­sue is a 280kW su­per­charged en­gine that be­gan life in a Honda Ac­cord Euro, over­hauled with race­spec com­po­nents and out­stand­ing at­ten­tion to de­tail. The six-speed gear­box has had the same treat­ment.

Opt for a sec­ond su­per­charger— com­plete with an in-dash dial to mod­er­ate up to 560kW— and the trans­versely mounted gear­box, devel­oped with Hollinger and com­plete with pad­dle shifters, is the trans­mis­sion of choice.

Built largely of car­bon-fi­bre and air­craft-grade al­loys, the Quantum tips the scales at less than 600kg. That’s a scary power to weigh ra­tio. It claims 2.6 sec­onds to hit 100km/h from rest and reaches 292km/h.

Yet I’ve never to see a car with the Quantum’s race­based set-up han­dle a re­peat­edly patched sec­tion of pub­lic road with such civil man­ners. Now it’s just up to pun­ters at the Aus­tralian Grand Prix— where this pocket rocket is on dis­play— to stump up the de­posits.
