With just days before its official test drives, a BMW 435i M Sport Package was showcased to the public.

The new BMW 4 Series goes on sale this summer and in the U.S. will be initially offered in the 428i and 435i configuration.

The drivetrain of the F32 BMW 435i is virtually identical to that of the current BMW 335i: the turbocharged inline six-cylinder with 306 horsepower. The engine can be paired to a six-speed manual transmission or eight-speed automatic.

The M Sports package for the BMW 4 Series Coupe will be available at market launch, and is positioned above the Sport Line. The M Sport Package includes revised front and rear aprons, large alloy wheels and some modifications for the interior, including sports seats and sports steering wheel. In combination with the M package, BMW offers the Estoril Blue Metallic color.

BMW 435i with rear-wheel drive starts at $46,000 while the M Sport is an additional $3,100.
