Audi TT ul­tra quat­tro con­cept

Shepparton News - Shepparton Car Weekly - - FRONT PAGE -

At Wörthersee 2013 in Ger­many, Audi will un­veil the TT ul­tra quat­tro con­cept – which com­bines min­i­mal weight and max­i­mum sporti­ness.

In ad­di­tion to the leg­endary Sport quat­tro S1, the lat­est RS mod­els and thor­ough­bred race cars in­clud­ing the Audi R18 e-tron quat­tro, which was the first hy­brid car to win the 24 Hours of Le Mans last year, will also be part of the ac­tion.

The Audi TT ul­tra quat­tro con­cept show car com­bines a lean 1111 kg to­tal weight with a 2.0 TFSI en­gine, which ef­fort­lessly pro­pels the coupé from a stand­still to 100 km/h in just 4.2 sec­onds.

Its power-to-weight ra­tio of 205 kW-per-tonne is on a par with thor­ough­bred su­per sports cars.

Even the cur­rent se­riespro­duc­tion car, with a body weight of just 206 kg plus 98 kg for the de­tach­able body parts, is tes­ti­mony to the out­stand­ing light­weight con­struc­tion ex­per­tise of Audi.

The en­gi­neers from In­gol­stadt and Neckar­sulm fine-tuned the Audi Space Frame in the cur­rent TT gen­er­a­tion to come up with the body for the Wörthersee show car, shed­ding an­other 43 kg from the body struc­ture. To­gether with op­ti­mised de­tach­able body parts, the re­sult is a weight sav­ing of 100 kg.

The Audi TT ul­tra quat­tro con­cept uses car­bon-fi­bre re­in­forced poly­mer (CFRP) through­out the rear end, the cen­tre tun­nel, in the B-pil­lars and in the roof. Mag­ne­sium com­po­nents in the floor and used as hinge re­in­force­ment re­duce weight even fur­ther.

The com­bi­na­tion of light­ness and sporti­ness is also re­flected in the looks.

Com­pared with the se­riespro­duc­tion model, the Audi de­sign­ers have honed the show car’s con­tours even fur­ther.

With its large spoil­ers, the TT ul­tra quat­tro con­cept proudly dis­plays its mo­tor­sport genes. The base of the rear wing is man­u­fac­tured as a sup­port­ing com­po­nent from milled alu­minium, while the wing, as a func­tional el­e­ment, is made of car­bon.

The Audi show car demon­strates the tech­ni­cal pos­si­bil­i­ties of an in­tel­li­gent mix of ma­te­ri­als.
