A prototype of the new Peugeot 308 GTI has been spied during its final testing phase, prior to a public debut set for October at the Paris Motor Show.

At a first glance this might look like a regular 308 but in reality it's the hotter GTI derivative as it features a lowered suspension, beefier alloy wheels and a dual exhaust setup. However, most of the body parts were sourced from the regular model to hide the car's true identity which will ride on sizeable 19-inch rims.

It will also come with stiffer springs and dampers together with larger brakes and a tweaked steering system. We remind you the company's ride and handling expert Christophe Valet hinted the forthcoming 308 GTI will have around 250 bhp (186 kW), "maybe more maybe less."

Power is expected to be provided by a revised 4-cylinder, 1.6-liter THP engine which will also be installed in the range-topping 308 R where it will probably churn 270 bhp (201 kW) and 330 Nm (243 lb-ft), as seen in the namesake concept. Expect the GTI to come out first this October while the R will be introduced sometime in 2015.
