The beating heart of the new Peugeot 308 GTi by PEUGEOT SPORT is the 1.6-litre THP S&S engine, available in outputs of 250hp (182kW) and 270hp (200kW). The unit is Euro 6-compliant, and the standard Stop&Start technology means both versions have CO2 emissions of just 139g/km. Combined Cycle fuel economy is equally impressive at 47.1mpg and both versions develop high torque of 330Nm at just 1,900rpm and feature a manual six-speed manual transmission.
The more powerful 270hp version sets a new record for power-to-weight ratio in its segment, at just 4.46kg per unit of horsepower. It can reach 62mph (100 km/h) in just 6.0 seconds, compared to 6.2 seconds for the 308 GTi 250, while the top speed in both cars is electronically limited to 155mph.
The GTi 270 version has everything required to rein in the power, with race-developed 380mm ventilated carbon discs at the front, mounted on aluminium hubs. Braking comes via four pistons (38mm and 41mm) in a fixed caliper and the rear discs have a diameter of 268mm.
Finely-tuned running gear ensures dynamic driving which inspires confidence. The pseudo-MacPherson strut in the front operates with precision, while the rear axle with its twist-beam system ensures a seamless pairing. These components also help reduce the weight of the 308 GTi, with a semi-hollow anti-roll bar and aluminium wishbones.
The entire vertical suspension system in the front is specific to the new 308 GTi, and including bespoke spring stiffness and shock absorber calibration. The anti-roll bar is more malleable to ensure a better match with the rear axle to enhance grip while cornering to increase road holding.
Exclusive to the GTi 270 version is an accomplished Torsen® limited-slip differential, incorporated into the transmission to improve cornering traction. By channelling the torque to the wheel with the highest grip, it makes it more able to accelerate faster out of bends than would normally be the case.
The engine runs on RON 95 or RON 98 fuel and injection pressure is 200bar. Maximum torque ranges from 1,900 to 5,000rpm, with power and torque perfectly regulated, even at higher rpm, due to the special ‘wastegate’ valve design.
The compression ratio is 9.2:1 due to state-of-the-art moving components, which include forged aluminium pistons of a competition-style design, strengthened conrods, polymer-enhanced bearings and reinforced bolts.
To ensure consistent performance, the pistons are cooled from below by a double oil spray system and the exhaust manifold is made of steel which can resist temperatures of up to 1,000°C. To tap the full potential of the engine, the 308 GTi by PEUGEOT SPORT is equipped with a supercharged air cooling system specially developed and installed below the front bumper.
The on-board electronics are in keeping with the GTi’s athletic temperament. The power steering is designed specifically to work in conjunction with the Torsen® technology.
The limited-slip differential also draws on new Traction Control guidelines to ensure optimal implementation. The sportier ESP design allows more latitude, with enhanced drift on bends. The ESP can be fully disconnected.
