Just as we thought Autodelta was going to chill out after the presentation of the 405Hp Alfa GT Super a couple of weeks ago, Alfa’s UK based partner announced that it’s updating the 147 GTA AM 3.7 Super with a more powerful version of the 3.7-litre supercharged V6. The car’s maximum power is up to 422 bhp at 7,000 rpm (from 400Hp ) and torque improved to 520 Nm.

Autodelta hasn’t given out any official performance figures yet, but just to get an idea, the current 400Hp 147 GTA AM Super has a top speed in excess of 180 mph (288 km/h) and 0-60 mph (0-97 km/h) time of 4.8 seconds. We’ll have more on Autodelta’s 147 GT AM Super after its official presentation at the Spa-Francorchamps Grand Prix circuit in Belgium this coming weekend (2-3 June). -Full Press release and high-res gallery after the jump

Autodelta to present 422 bhp 147 GTA AM 3.7 Super at SpaItalia this weekend

Autodelta is pleased to announce that it will be present with a comprehensive line up of its high-performance bespoke Alfa Romeo models at SpaItalia this coming weekend (2-3 June) at the famous Spa-Francorchamps Grand Prix circuit in Belgium. Attending this edition of SpaItalia is made even more special, this year Autodelta is celebrating its 20th anniversary as the leading engineering centre for developing the ultimate road-going Alfa Romeo high-performance cars.

Leading out the exclusive Autodelta model range at SpaItalia will be a first official showing for our most powerful interpretation of the Alfa 147 GTA theme yet: the 422 bhp Autodelta 147 GTA AM 3.7 Super. This new version further builds on the impressive upgrades we have already made to the Alfa V6 engine: capacity 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.

Autodelta created its first 3.7-litre supercharged Alfa 147 GTA conversion exactly two years ago, the car making its preview appearance on the inaugural ‘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.

We are now very pleased to introduce this full option, the Autodelta 147 GTA AM (‘Autodelta Maggiore’) 3.7 Super, as an official package available for immediate ordering. The car will be presented at SpaItalia this coming weekend and will be demonstrated on the famous 6.976-km Grand Prix circuit on both Saturday and Sunday by our test driver.

To complement the debut of the 422 bhp 3.7 litre version at the Spa circuit, which nestles in the glorious undulating hills of the Belgian Ardennes forest, we will present the 341 bhp Autodelta 147 GTA AM 3.2 Super. Also present at SpaItalia will be our most exciting new model introduction of the last year and a car that ushered in a new era at Autodelta, the 341 bhp Autodelta Brera J5 3.2 C. Previewed last summer in Monte Carlo and commercialised in February 2007 this high-performance bespoke car has created impressive worldwide demand already. Completing our current model range will be the 400bhp Autodelta 156 GTA AM 3.7 Super.

Jano Djelalian says: “SpaItalia is always an excellent event and we are especially looking forward to attending this year’s edition. We’re delighted to bring our full model range and in particular to present our most extreme project yet, the 422 bhp version of the Autodelta 147 GTA AM 3.7 Super. We always are keen to show our cars in the conditions they are designed for, so putting this car on track at Spa is the perfect official introduction.”

SpaItalia – now in its sixth edition – has quickly grown to become one of Europe’s leading Italian car extravaganzas. With the distinct ‘track’ element central to the two-day programme, the event showcases a glittering array of Italian machinery. It takes place on the evocative Spa-Francorchamps circuit. First opened in 1921, this is one of the world’s fastest and most demanding circuits, and a real test of driver ability. This year the ‘Featured Marque’ at SpaItalia is Maserati poignant as the Trident brand is celebrating the occasion of the fiftieth anniversary of Juan-Manuel Fangio’s F1 World Championship title claimed at the wheel of the legendary 250F. A highlight of the event will be the presence of Maria Teresa de Filippis the first woman to drive in an F1 Grand Prix and a lady who is synonymous with Maserati. The 2007 SpaItalia event is scheduled for Saturday and Sunday, June 2 & 3.
