The 2017 Range Rover Autobiography LWB with a 3.0 L petrol engine is the ultimate expression of refined luxury and commanding presence in a full-size SUV. Its supercharged 3.0 L inline-6 petrol engine produces strong power and torque (typically around 355–394 hp with up to ~550 Nm depending on exact configuration), paired with an advanced 8-speed automatic transmission and permanent all-wheel drive for smooth, confident performance. The Autobiography’s long wheelbase enhances rear-seat comfort, offering executive-class seating, premium leather, ambient lighting, and top-tier technology for both driver and passengers. With sophisticated Terrain Response off-road capability and a suite of cutting-edge safety and driver-assist features, it blends effortless on-road cruising with true all-terrain ability. Performance is equally impressive for such a refined SUV — with brisk acceleration and a governed top speed in the region of about 225 km/h (140 mph).
