Lexus Group Vice President Jeff Bracken has announced at least one, if not two, models will premiere in January 2015 at the North American International Auto Show in Detroit.

Talking to WardsAuto, Bracken said Lexus will bring to the forthcoming NAIAS at least one new model while a second car is possible as well. He didn't divulge the identity of these two new vehicles but chances are he was referring to the GS F and RX.

The GS F was spotted numerous times while undergoing testing and is expected to get an RC F-sourced V8 5.0-liter engine upgraded to deliver about 500 bhp (373 kW) and 400 lb-ft (541 Nm) whereas in the RC F it packs 467 bhp (348 kW) and 389 lb-ft (541 Nm). Output will be channeled to the wheels through an eight-speed transmission that should grant a 0-60 mph (0-96 km/h) run in approximately 4.5 seconds before hitting a top speed in excess of 170 mph (273 km/h).

Details about the next generation RX are scarce at the moment but Lexus NX assistant chief engineer Kei-Ichi Nishiyama previously stated the new RX might be transformed into a three-row crossover since "there is lots of demand [for seven seats] from the US market." In addition, Lexus Australia chief executive Sean Hanley backed up the statement by saying Lexus has been studying the possibility of installing seven seats in the new RX set to grow in size to accommodate the additional passengers and also as a measure to distance itself from the NX.

Lexus could bring two new models to 2015 NAIAS in January, likely GS F and RX
