The flared wheel arches houses 21 inch wheels clothed in 295/30 ZR 21 tires. Along with the BRABUS chassis kit that reduces ride height by 30 mm, and a high-performance brake system, the Widestar illustrates the true highway potential of the GLK-Class. The required propulsion is generated by a modified V6 diesel engine patterned on the 320 BlueTEC unit with innovative AdBlue technology from other versions presently available in the USA. Through the ECOPowerXtra tuning kit, the Widestar engine produces 190 kW/258 hp and provides 610 Nm of torque. All of this add up to produce remarkable performance statistics. The acceleration from 0-100 km/h is reached in 6.9 seconds and the Widestar reaches a ceiling speed of 240 km/h.
