Quantum XtremeAlthough unashamedly of Lotus 7 inspiration, the Xtreme offers refreshing styling and surprising practicality - the lockable boot has the capacity to house all of the weather gear, as well as a weekend bag!

 

Originally called the Savant and markted by Sector Three Sportscars it was purchased by Quantum Sports and renamed the Xtreme.  The car is based around an exceedingly high quality stainless steel monocoque chassis, the torsional stiffness of which has been tested at over 4000 NM, far superior to the 2000 NM typically achieved by traditional spaceframe construction. All fixing holes are laser cut into the chassis - even for the items such as the wiring loom, brake pipes and fuel lines - with captive nuts where required. All components can therefore be easily and precisely fixed to the chassis, without the requirement of any specialist tools.

The entire suspension set up is designed and manufactured specifically for the Xtreme, so there is no dependence on Sierra components, which would be completely unsuitable for this type of car. This combination of race-derived suspension and uncompromising chassis gives class leading ride and handling.
