Buick has come a long way in the past few years and a new report is indicating the brand is going to revive their performance aspirations by bringing back the Grand National and GNX.

Car & Driver says the sedans will be launched in 2015 and ride on the Alpha rear-wheel drive that currently underpins the Cadillac ATS. Unsurprisingly, the Grand National is expected to be offered with a variety of ATS-sourced engines including a turbocharged 2.0-liter four-cylinder that develops 272 bhp (203 kW) and 260 lb-ft (352  Nm) of torque as well as a 3.6-liter V6 that churns out 321 bhp (239 kW) and 274 lb-ft (371 Nm) of torque.

The GNX, on the other hand, would be available exclusively in black and come with a twin-turbo 3.6-liter V6 that develops approximately 400 bhp (298 kW).

Automatic and manual transmissions are expected as well as a possible all-wheel drive system.
