2017 Land Rover Discovery SD4: 7 Pros And Cons

The 2017 Land Rover Discovery SD4 marks a bold evolution for the iconic SUV lineup, introducing a lighter aluminum architecture, refined diesel powertrain, and enhanced everyday usability while preserving legendary off-road credentials. This model shifts away from traditional body-on-frame construction to a more sophisticated platform shared with premium siblings, delivering improved handling and efficiency without sacrificing rugged capability.

Design and Build Innovations

Externally, the 2017 Discovery adopts a sleeker, more aerodynamic profile compared to its boxier predecessor, reducing weight by approximately 480kg in base configurations and boosting overall agility. Ground clearance reaches up to 283mm in off-road modes, with increased approach, departure angles, and wading depth for superior terrain conquest. The full-size spare wheel and 85-liter fuel tank underscore its adventure-ready ethos, paired with a braked towing capacity of 3500kg.

Inside, a split-level cabin philosophy employs premium leathers and soft-touch materials above the beltline for luxury appeal, transitioning to durable, wipe-clean surfaces below to withstand muddy exploits. The 12.7m turning circle aids maneuverability despite the 2923mm wheelbase, making it less cumbersome in tight spaces than expected for its size.

Powertrain: Ingenium 2.0-Liter Diesel Excellence

Central to the SD4 is Jaguar Land Rover’s Ingenium 2.0-liter twin-turbo diesel, producing 237hp at 4000rpm and 500Nm from 1500rpm for strong low-end pull. Mated to an 8-speed automatic and permanent four-wheel drive with locking center differential and twin-speed transfer case, it ensures seamless power delivery across terrains. Reviewers note its refinement, describing it as the quietest iteration yet, though it exhibits some roughness under hard acceleration.

Fuel claims of 6.5L/100km prove optimistic; real-world figures hover around 9L/100km even on mixed routes, impacted by the 2223kg kerb weight. A speed-lowering function drops ride height by 13mm above 105km/h to cut drag, though benefits vary by region.

On-Road Dynamics and Comfort

Refinement shines on tarmac, with a composed ride that cossets occupants over long hauls. Air suspension provides excellent damping, allowing controlled body roll in corners while maintaining stability. The light, responsive steering builds confidence, making the Discovery feel smaller than its dimensions suggest. Scores for driving and comfort average 4.0/5, praising its dual-purpose prowess.

Seats, however, draw minor criticism for firm padding, though the cabin remains plush overall. Noise insulation excels, creating a serene environment even at highway speeds.

Off-Road Prowess Redefined

Ditching the ladder frame hasn’t dulled capabilities; enhanced metrics like +43mm ground clearance and +200mm wading depth position it ahead of many rivals. Terrain Response systems, low-range gearing, and all-terrain progress control enable effortless obstacle navigation, from rocks to ruts. Permanent 4WD with on-demand locking ensures traction in extremes, earning high utility marks at 4.5/5.

Interior Space and Practicality

The cavernous seven-seat layout accommodates adults across all rows, with generous legroom, headroom, and elbow space. Individually power-folding second- and third-row seats vanish flat, revealing vast cargo holds; a fold-down rear shelf adds versatility. Storage abounds, from door bins to overhead consoles, amplifying family appeal.

Utility earns top billing, blending clever design with seven-passenger flexibility.

Technology and Infotainment

The InControl Touch Pro system features a 10-inch touchscreen, lauded for usability post-boot-up despite slow startup. Apple CarPlay, Android Auto, and navigation integrate smoothly, with voice controls and dual-zone climate enhancing connectivity. Tech scores 3.5/5, reflecting solid but not class-leading execution. Safety aids like adaptive cruise and lane-keeping add polish.
