A new member of the Alfa Romeo Giulia family is in the works and it may revive one of the most cherished Alfa nameplates. Alfa Romeo Giulia coupe should to offer two powertrains that will incorporate an F1-style energy recovery system (ERS).

One engine expected to make it under the hood of the coupe. That may revive the Sprint name, a turbocharged 2.0-liter engine borrowed from the Giulia Veloce sedan good for 345 hp. A hotter offering is  the turbocharged 2.9-liter V6 borrowed from the Giulia Quadrifoglio. It is expected to churn out an eye-watering 641 hp. This would make it the most powerful Alfa in the lineup, with its sights set on the likes of the Audi RS5, Mercedes-Benz C63 S Coupe and the BMW M4 DTM.

The ERS system that the Giulia coupe’s powertrain will use should be a version of the HY-KERS system. It is made by Magneti Marelli and Ferrari for the LaFerrari, optimized for performance. The ERS system essentially uses the electric motor’s low-end torque to complement the gasoline engine’s torque curve; the result is better fuel consumption and cleaner emissions compared to conventional gasoline engines with comparable horserpower outputs.

A diesel version could also make the lineup

The coupe will probablyvto use the existing Giulia engines from the bottom of the range. That also includes turbocharged 2.0-liter engine tuned to 280 hp, in addition to a 505-hp Quadrifoglio V6. A diesel version could also make the lineup. That’s not a model we expect to make it to North America.

The Giulia coupe will use Giulia sedan bodywork up front but will feature a more distinct greenhouse and rear fascia, along with longer doors. The biggest question is whether Alfa will make the Giulia coupe or  it will have a conventional trunk like the Mercedes-Benz C-Class Coupe. The former option seems like the better bet at the moment given the success of the Audi A5 and its five-door Sportback siblings, but regardless of the layout the Alfa coupe should reenergize Giulia sales given the relatively slow start experienced by the sedan.
