Two GT models are offered, one petrol and one diesel. While the option of two fuel types gives buyers greater choice, the petrol variant is only available with a manual transmission and the diesel is auto-only.
While the 308 GT makes do with 'just' 151kW of power and 285Nm of torque from its turbocharged 1.6 litre four-pot, its twin-scroll turbocharger, variable valve timing, variable intake cam lift and direct-injection tech gives it a broad powerband.
It's enough grunt to take the 308 GT to 100km/h from standstill in 7.5 seconds, on its way to a top speed of 235km/h.
The 308 GT diesel receives a 133kW/400Nm 2.0 litre turbo Diesel engine, capable of hitting 100km/h in 8.4 seconds. Those numbers aren't quite in hot hatch territory, but the GT's performance is definitely 'warm'.
Both engines are bolted to six-speed transmissions, though the petrol is only available with a manual and the diesel exclusively an automatic.
Rolling on 18-inch alloys wrapped in Michelin Pilot Sport 3 rubber, the 308 GT gets a suspension that's 7mm lower at the front and 10mm lower at the rear, along with stiffer springrates and specific damper settings.
As with the rest of the 308 range the GT features electric power steering, albeit with a slightly faster rack ratio.
Meanwhile, braking hardware has been upsized to cope with the GT's extra speed.
Up front there are 330mm x 30mm ventilated discs and bigger sliding calipers, paired to 268mm solid discs at the rear.
Though many price competitors are faster and more powerful, the 308 GT makes up for it with an extensive list of standard equipment.
Key among these features are adaptive radar-assisted cruise control, a blind spot monitor, LED headlamps, a GT-specific bodykit, alloy pedals, black headliner and a performance meter that displays power, torque, turbo boost pressure and lateral G forces.
And that's on top of the features that the GT shares with the high-spec Allure.
Features like satellite navigation, a 6.9G onboard music storage drive, Bluetooth, two USB ports, keyless entry and ignition, self-parking function, dual-zone climate control and electric massage seats.
Both the petrol and diesel are specced identically, though the diesel also gains steering wheel mounted shift paddles for manual control of its transmission. The sole upholstery option is an Alcantara/pleather combo.
