To make the most of the chassis, the PEUGEOT 308 GTi by PEUGEOT SPORT contain the 1.6L THP S&Si petrol engine 270 or 250 ch. Drawing on the full expertise of the PEUGEOT SPORT engineers, its 200 kW of poweri and 330 Nm of torque are perfectly regulated, even at high speeds, thanks to the specially designed control valve for the wastegatei. Furthermore, the exhaust manifold is made of steel, and is capable of withstanding temperatures of up to 1,000°C.
State-of-the-art moving components include forged aluminium pistons, strengthened segmentation and connecting rods, polymer-enhanced bearings and reinforced bolts. To ensure consistent performance, the pistons are cooled from below by a double oil spray system.
To contain the increased torque of up to 330 Nm, the six-speed manual gearbox has been reinforced. The two shafts have been shot-blasted, and the gears subjected to intense carbonitriding. By boosting their carbon and nitrogen content, this thermochemical process has improved the ability of these parts to withstand wear and tear and fatigue. The output axle has also been shortened, to improve acceleration.
Weighing in at a mere 1,205 kg, the 308 GTi by PEUGEOT boasts an excellent weight/power ratio of 4.46 kg/hpi. It also pulls off the striking feat of generating combined cycle CO2 emissions of just 139 g/km, and using just 6.0 l/100 km in a combined cycle - a record for its category - 8.1 l/100 km in an urban cycle and 4.9 l/100 km in an extra-urban cyclei.
