Autodelta Alfa GT 3.7 Super 405Hp: Detailed Info & High Res Images

11.05.2007 Autodelta present the world’s fastest Alfa GT – the 293 km/h 405 bhp Autodelta GT 3.7 Super

Autodelta is pleased to present for its world première the most dynamic and powerful version of the Alfa GT Coupé yet – the 405 bhp supercharged Autodelta GT 3.7 Super. With its top speed of 293 km/h (182 mph) and a 0-100 km/h (0-62 mph) time of 4.9 seconds the Autodelta GT 3.7 Super offers the driver supercar level performance coupled with the car’s famous driveability and practicality.

Introduced four years ago, the Alfa GT Coupé, styled by famed historic Italian design house Bertone, is a gorgeous, sleek and very agile, yet at the same time truly practical, four-seat coupé which immediately won plaudits and awards as well as a loyal following worldwide: a true Alfa Romeo in every sense of the word. Now the new Autodelta GT 3.7 Super takes the GT Coupé theme to the ultimate performance level. It follows on from the market success of the firm’s previous work with the 3.2-litre Alfa GT model: the 320 bhp Autodelta GT 3.2 Super (2004) and the 341 bhp Autodelta GT 3.2 Super Evo version (2005), by raising the Alfa V6 engine and chassis package to even more extreme performance levels.

“Our customers continually push us forward, demanding ever more performance from Alfa Romeo models, and following the 3.2 Super and Evo versions we have had many requests to maximise the Alfa GT’s potential with a 3.7-litre supercharged version,” says Autodelta Managing Director Jano Djelalian. “We have a vast experience with the chassis of this car, and knew it was more than capable of handling the serious power and torque increases that would result from this project – and then transmitting them to the road in a useable and effective manner.”

The new car sees the Alfa GT’s 3.2-litre engine’s capacity increased to 3,750cc, and harnessed with the space-efficient Rotrex C38-81 centrifugal supercharger. The engine development includes extensive cylinder head improvements, new larger fuel injectors with revised spray patterns to optimise combustion and emissions, and a Ferrari-derived throttle body. The car also receives new tubular exhaust manifolds and a complete exhaust system specially designed for the requirements of this upgrade. The result, combined with further chassis, transmission and aerodynamic developments is earth shattering. The Autodelta GT 3.7 Super boasts maximum power of 405 bhp at 6,800 rpm and 508 Nm (375 lb/ft) of torque at 4,800 rpm. The standard Alfa GT 3.2 V6 by comparison offers 240 bhp and 300 Nm (221 lb/ft).

The new Autodelta GT 3.7 Super can reach a maximum speed of 293 km/h (182 mph) and boasts a 0-100 km/h (0-62 mph) acceleration time of 4.9 seconds – blistering performance from what is a perfectly sorted car. (Standard Alfa GT Coupe V6 top speed is 243 km/h while the 0-100 km/h time is 6.7 seconds). The torque availability of the Alfa V6 engine – one of the most famous units in the brand’s almost century long history – is truly impressive, the power curve running smoothly from tickover to the redline at 7,400 rpm.

“The Arese-built Alfa V6 is an excellent engine,” says Jano, “we have more than twenty years of experience developing it to the maximum, and it quite simply responds to everything we want to do to it. The Alfa GT Coupé provides us with all the right ingredients to work with – in the engine and chassis area – and we are all delighted with the results we have achieved with the Autodelta GT 3.7 Super.”

The improvements made to the engine are complimented by extensive remapping to the ECU, while the front-wheel-drive car is able to effectively put the additional power down on the road through the incorporation of an Autodelta-developed and specially manufactured Limited Slip Differential (LSD). Autodelta also fit different gearbox ratios, depending on the customer’s specific requirements.

This is not just a very powerful machine for trackdays or special occasions, but an effective, practical car ready for day-to-day use, fully able to use all its 405 bhp and 508 Nm to enhance the owner’s sensory experience under all driving scenarios. Most Autodelta customers’ demand a high performance Alfa Romeo which is suitable every use, and Autodelta’s engineers regard it as their priority to fulfil this demand.

The Autodelta GT 3.7 Super comes with the enhanced aerodynamic package of the GT Super, including a deeper spoiler that supplies and optimises airflow to the intercooler. The rear bumper assembly incorporates a ‘diffuser’. Interior trim upgrades are optional, including Alcantara trim on the dashboard and panels, as well as bespoke leather packages.

The full Autodelta GT 3.7 Super package is now available for immediate ordering from the London factory or from our worldwide network of authorised dealers.
