BMW 730Ld SE 242Bhp Review: Efficient Executive Saloon

The BMW 730Ld SE represents a compelling choice for discerning buyers seeking a full-size luxury saloon with impressive diesel credentials. This extended-wheelbase model combines the prestige of the 7-Series nameplate with pragmatic efficiency, offering a sophisticated alternative to conventional petrol-powered executive vehicles. The vehicle bridges the gap between traditional luxury expectations and contemporary demands for sustainable motoring, delivering a persuasive package that justifies consideration despite premium pricing.

Powertrain Architecture and Performance Characteristics

At the mechanical heart of the 730Ld SE sits a 3.0-litre six-cylinder diesel engine that produces a respectable 242 brake horsepower. This powerplant exhibits characteristics typical of modern diesel engineering, delivering smooth operation alongside meaningful performance credentials. The engine generates substantial torque, with a maximum of 540Nm available across a broad power band ranging from 1,750rpm to 3,000rpm. This expansive torque curve ensures that overtaking manoeuvres remain effortless, whether navigating urban congestion or cruising highway sections.

The diesel unit demonstrates surprising dynamism for an engine of this displacement. BMW engineers have calibrated the power delivery to feel responsive and immediate, characteristics that elevate the driving experience beyond mere duty-cycle performance. The acceleration profile compares favourably against rival offerings, including competitors such as the Audi A8 3.0 TDI and Mercedes S320 CDI. Owners report that the engine feels less laboured than competing diesel mills, contributing to an overall impression of refinement and capability.

Efficiency and Running Cost Considerations

One of the primary arguments supporting the 730Ld SE centres on its fuel economy credentials. The vehicle achieves an average consumption of 39.2mpg, a compelling figure when considering the saloon’s substantial kerb weight of 1,865kg. This efficiency gain becomes particularly pronounced during motorway cruising, where the engine operates at just 1,700rpm at 70mph, a remarkably low figure that translates to quieter, more relaxed highway travel.

Real-world testing demonstrates that owners frequently exceed the official combined consumption figures when primarily undertaking longer journeys. The efficiency characteristics remain consistent even when employing full throttle, as the diesel engine maintains its fuel-sipping tendencies despite delivering its 242bhp output. For fleet managers and private buyers contemplating five-year ownership, the fuel economy advantage over petrol rivals translates into hundreds of pounds in annual savings.

CO2 emissions also rank favourably within the luxury saloon class, a factor that influences road tax obligations and corporate environmental metrics. The combination of low consumption and respectable emissions performance addresses growing concerns about premium vehicle ownership costs, particularly during periods of elevated fuel prices.

Transmission and Driveline Integration

The 730Ld SE employs an eight-speed automatic transmission that works in seamless harmony with the diesel engine. This gearbox represents the contemporary standard for premium saloons, offering rapid shifts and intuitive response to driving inputs. The transmission includes stop-start technology as standard, automatically deactivating the engine during traffic congestion to reduce fuel consumption and emissions further.

The drivetrain architecture incorporates brake energy recuperation, a system that captures kinetic energy during deceleration and redirects it to charge the electrical system. Electric power steering replaces traditional hydraulic assistance, contributing to the overall efficiency narrative while maintaining steering precision and feedback.

Chassis Dynamics and Driving Refinement

Despite its considerable dimensions and substantial mass, the 730Ld SE demonstrates surprising agility and responsiveness. The chassis benefits from Drive Dynamic Control with variable adaptive dampers, offering five distinct settings that modify suspension stiffness and body control characteristics. These range from ECO PRO, optimised for fuel conservation, through Comfort and Comfort+ modes emphasising ride quality, to Sport and Sport+ configurations favouring more aggressive handling responses.

The available electronically controlled four-wheel steering system further enhances the saloon’s capability. This sophisticated technology reduces turning circles during low-speed urban manoeuvres while sharpening responses at higher velocities, effectively making the large BMW feel significantly more compact than its actual footprint suggests. The combination of advanced suspension tuning and intelligent steering geometry creates a saloon that can challenge notably smaller vehicles for driving enjoyment and dynamic engagement.

Owners consistently report that the 730Ld SE wafts along motorways with minimal fuss, the suspension absorbing road imperfections before they reach the passenger compartment. The refined diesel engine, combined with comprehensive sound insulation and laminated glazing, ensures that cabin noise remains subdued even during sustained high-speed travel.

Interior Accommodation and Luxury Provisioning

The extended wheelbase variant of the 730Ld SE provides extraordinary rear legroom, a characteristic that defines the entire luxury saloon category. Passengers enjoy acres of rear legroom, ensuring that business executives and family members can recline in complete comfort during extended journeys. The spacious cabin reflects the saloon’s positioning at the pinnacle of the executive vehicle market.

The SE trim level, identified as the range’s quality sweet spot, includes rear parking sensors as standard equipment—a practical necessity given the vehicle’s dimensions—alongside a soft-close tailgate mechanism that prevents passengers from being disturbed by boot slamming. These seemingly minor details reflect BMW’s attention to operational convenience and the passenger experience.

The interior design employs premium materials throughout, with leather upholstery, wood trim inlays, and metallic accents combining to create an atmosphere of restrained elegance. Climate control operates independently across multiple zones, allowing driver and passengers to establish their preferred temperature settings without compromise. Storage compartments are thoughtfully distributed throughout the cabin, accommodating modern travel necessities including mobile devices and documents.

Technology and Connected Vehicle Systems

The 730Ld SE integrates BMW’s comprehensive technology portfolio, positioning the saloon at the forefront of connected vehicle design. Satellite navigation provides turn-by-turn guidance with real-time traffic integration, while the infotainment system displays information across high-resolution displays positioned within easy sight lines. Manual controls supplement touchscreen interfaces, ensuring that frequently-accessed functions remain accessible without requiring extended menu navigation.

The radio system incorporates multiple tuning modes and preset stations, catering to diverse listening preferences. Speakers strategically positioned throughout the cabin deliver balanced audio reproduction, with quality sufficient for appreciating both music and comprehensive voice guidance from navigation systems.

Visibility and Safety Considerations

The saloon’s commanding seating position and extensive glazing provide good forward and lateral visibility, mitigating concerns that often accompany large vehicles. Auto-dimming mirrors prevent driver distraction when vehicles behind project bright headlights, particularly valuable during night-time driving. Full electric windows operate smoothly at both front and rear, while power mirrors incorporate adjustable heating elements for winter operation.

Manual Control Options and Driver Engagement

Despite its automatic transmission, the 730Ld SE offers manual gear selection via dashboard-mounted buttons, permitting drivers to override the transmission’s automatic logic when desired. This feature enables enthusiasts to maintain engagement during spirited driving while supporting rapid descent management on mountain passes. The implementation uses physical buttons rather than steering wheel-mounted paddles, positioning controls within convenient reach during normal driving.

Value Proposition and Market Positioning

At approximately £54,000, the 730Ld SE occupies an elevated price tier that requires careful consideration. However, the economy and CO2 advantages over competing petrol saloons generate substantial operational savings that accumulate across ownership periods. Buyers prioritising initial acquisition cost should explore pre-owned examples, which offer similar capabilities at significantly reduced prices.

The new exterior styling refreshes appeal beyond traditional 7-Series supporters, introducing design language that contemporary luxury purchasers recognise and appreciate. If positioned within the market for premium saloons, comparatively few models successfully match the 730Ld SE’s combination of comfort, technological sophistication, performance, and efficiency.
