Su­per­cars even more spec­tac­u­lar

NT News - Motoring - - NEWS - By MARK HINCH­LIFFE

THE cars will look the same, but the rac­ing could be very dif­fer­ent when the V8 Su­per­car Car of the Fu­ture ve­hi­cles hit the track in 2012.

V8 Su­per­cars Aus­tralia last week lifted the veil off a pro­to­type chas­sis be­ing built in Queens­land un­der the su­per­vi­sion of PACE In­no­va­tions’ Paul Cepr­nich.

Var­i­ous race teams have been in­vited to ten­der de­sign as­pects of the new cars and the de­signer of the new in­de­pen­dent rear sus­pen­sion be­lieves it could lead to more spec­tac­u­lar rac­ing and more pass­ing.

Race en­gi­neer for Craig Lown­des at Triple Eight Rac­ing Jeromy Moore said the in­de­pen­dent sus­pen­sion should work bet­ter on bumpy tracks and al­low more than one rac­ing line through a corner.

‘‘It will be cheaper than a live rear axle be­cause cur­rently teams are spend­ing big dol­lars try­ing to make gold out of lead,’’ he said.

‘‘It’s not un­com­mon to spend $150,000 on de­sign­ing a half-de­cent live axle.

‘‘Al­most all rac­ing these days uses in­de­pen­dent rear sus­pen­sion, ex­cept for NASCAR.’’

He said the in­de­pen­dent rear sus­pen­sion would al­low for more vari­a­tion in set-up, cre­at­ing per­for­mance dif­fer­ences among the teams.

‘‘There will be more ad­just­ment in the rear,’’ Moore said.

‘‘In­stead of just chang­ing the roll cen­tre you can change the cam­ber gain, roll cen­tre mi­gra­tion and bump steer.

‘‘In­de­pen­dent sus­pen­sion will also put the power to the ground eas­ier on bumpy tracks and al­low more corner speed and more rac­ing lines through a corner so you can pass around the out­side, clip the kerb or go off the rac­ing line.’’

Cepr­nich said they had com­pleted the con­trol floor and roll cage for the first car, the area which would be the same re­gard­less of the man­u­fac­turer.

‘‘This in­cludes the roll cage, chas­sis and nonOE (orig­i­nal equip­ment) el­e­ments of the car,’’ he said.
