The car features a stronger and lighter-weight body compared with the normal Audi R8 V10 and is equipped with a number of cosmetic revisions. It also receives changes to the suspension to improve handling and some engine tuning, and is being dubbed as the fastest drop-top Audi ever made.
Featuring the same 5.2-litre FSI V10 engine as the R8 GT Coupe, producing 412kW of power (an additional 26kW over the standard V10) and 539Nm of torque (additional 9Nm), the GT Spyder is expected to sprint from 0-100km/h in around 4.0 seconds.
Overall weight of the Spyder is likely to come close to the standard V10 Coupe's figure of 1620kg. All versions of the R8 GT Spyder will come equipped with the R tronic dual-clutch transmission due to its lighter weight and higher-performance capabilities.
Just 333 of the Spyder GTs will be headed for international showrooms at the beginning of 2012, after the an official unveiling at the Frankfurt Motor Show in September, and a first glimpse at this year's Le Mans event in June.
