Autodelta will unveil this week-end (2-3 June) at SpaItalia a comprehensive line up of its high-performance bespoke Alfa Romeo models. Also this year Autodelta is celebrating its 20th anniversary as the leading engineering centre for developing the ultimate road-going Alfa Romeo high-performance cars.
<>At SpaItalia, Autodelta will unveil the most powerful interpretation of the Alfa 147 GTA theme yet: the 422 bhp Autodelta 147 GTA AM 3.7 Super. The capacity for the Alfa V6 engine is increased to 3,750cc, a remapped management system, and a Ferrari-derived throttle body, coupled to the fitting of a Rotrex C38-81 supercharger delivering 0.75 bar of boost; now all taken to a new even higher level - bringing the car’s maximum power up to 422 bhp at 7,000 rpm (standard Alfa 147 GTA power is 250bhp at 6,200 rpm) and torque improved to 520 Nm.
The first 3.7-litre supercharged Alfa 147 GTA conversion was created two years ago and unveiled at the ‘Autodelta European Tour’ of 2005. The arrival of this dramatic package, which initially had 400 bhp, created much attention and it was requested by a number of customers.
To perfect this package fully and develop a highly dynamic chassis capable of delivering all this performance and still offer optimum day-to-day driveability, our engineering team has embarked on an intensive development programme over the last six months that has also seen our test cars in track action conducting extensive R&D programmes of major race circuits including Donington Park, Silverstone and the Nürburgring. Additional work has been carried out on the Alfa V6 engine’s cylinder head, block and internals as we have perfected this package, while the upgraded suspension features new spring rates from the dedicated coilovers and revised suspension components, as well as new anti-roll bar, and wheel geometry, adjustments. Autodelta’s own in-house developed limited slip differential is an integral part. The bespoke package includes a new aerodynamic rear under wing.
On display at SpaItalia will also be: the 341 bhp Autodelta 147 GTA AM 3.2 Super, the 341 bhp Autodelta Brera J5 3.2 C and the 400bhp Autodelta 156 GTA AM 3.7 Super.
