The new 308 variants will be not only be available in a choice of body styles, but buyers will also be able to pick between boosted petrol and diesel motors.
The petrol mill squeezes 153kW of power and 285Nm of torque from its 1.6 litres of displacement thanks to direct injection and a twin-scroll turbo. Power is sent to the front wheels via a six-speed manual, while automatic engine start/stop is on hand to improve fuel economy.
Those who opt for the diesel will find 134kW of power and 400Nm of torque available from the 2.0-litre turbo engine. The diesel is mated exclusively with a six-speed automatic transmission that's equipped with steering wheel paddles.
The GT rides on Michelin Pilot Sport 3 tyres that are wrapped around uniquely designed 18-inch alloy wheels. Peugeot claims that each engine variant will receive its own lowered suspension tune, with stiffness increased by between 10 and 20 per cent depending on the drivetrain.
At the front both the wagon and hatch employ 330mm disc brakes; at the rear the hatch utilises 268mm discs, while the wagon has larger 290mm rotors.
The standard Driver Sport Pack, which can be switched off, adds red instrument lighting, a firmer feel for the electric power steering system, louder engine note and a more responsive accelerator to the equation.
All 308 GT variants feature extra air intakes at the front, black wing mirrors, LED headlights with sequential indicators, and a perforated leather steering wheel. Other available equipment includes blind spot monitoring, automatic emergency braking, radar-guided cruise control, and automated parking.
In Europe, the Peugeot 308 GT will head into showrooms at the beginning of 2015. It's unknown at this stage whether the GT will be making its way down under.
