The 2014 Jeep Grand Cherokee SRT8 has been spied undergoing testing.

Modestly disguised, the prototype is wearing a standard facelifted body. It features a new front fascia with a revised grille and restyled headlights.

The cabin has a new instrument cluster, revised switch gear and an updated infotainment system with a larger display. We can also see a new gear knob and additional metallic accents.

Power will likely come from a 6.4-liter HEMI V8 engine with 470 hp (350 kW / 476 PS) and 465 lb-ft (630 Nm) of torque. It should enable the model to accelerate from 0-60 mph in 4.8 seconds and hit a top speed of 160 mph (257 km/h).

The facelifted Grand Cherokee could be introduced at the 2013 North American International Auto Show.
