Underneath the bonnet is a 525bhp, 461lb ft, 5.0-litre, supercharged V8 engine. The model also boasts increased ground clearance, body and suspension lifts, greater wheel articulation, tuned Terrain Response 2 system and hydraulic active roll control - a first for a Discovery.

Customers love the Discovery's versatility and capability and we are delighted to offer UK customers even more choice with the auditor of the Si4 300hp engine."
