Autodelta's Supercharged Alfa Romeo Brera S & J4 159

Few cars on the road – at any price – have the presence of an Alfa Romeo. Unfortunately their performance seldom keeps up with their looks. That's where aftermarket modifiers come in.

Last year the Italian automaker contracted British motorsport concern Prodrive to help it out in the performance department. Their answer was the Brera S, removing much of the aggressively-styled coupe's weight and fine-tuning the suspension. Now Autodelta is getting in on the action. The English tuning house has taken Prodrive's Brera S coupe and strapped on a supercharger good for 347 horsepower.

The power upgrades are also available on the Brera's four-door counterpart, the 159, which Autodelta transforms into the J4 3.2 Compressore. The pair were unveiled at London's exciting MPH09, but you can see them for yourself in the gallery below.
