A recent report indicates that Buick plans on reintroducing the Grand National, GNX and T-Type models.
These three performance nameplates were very popular during the 80s, and they all will be reinvented as sedans featuring GM's RWD Alpha platform. The Grand National is expected to get a new twin-turbo V6 3.6-liter engine with output between 350 hp (261 kW) and 400 hp (298 kW). This power unit will be shared with the T-Type which will also borrow the suspension setup. While the latter will be offered in various exterior colors, the GN will be sold exclusively in black just like the original.
As for the GNX, this could feature GM's new LT1 V8 engine that will power the 2014 Corvette (C7). It is a 6.2-liter unit with an estimated output of 450 hp (336 kW) and 450 lb-ft (609 Nm) of torque.
These three new models could debut at the 2014 Detroit Motor Show.
