INTRODUCTION

The BMW 745Le xDrive, launched in 2019 as part of the G12 7 Series’ Life Cycle Impulse (LCI) facelift, represented a significant step in BMW’s electrification strategy. Built on the extended wheelbase version of the G12 platform (also known as the 7 Series Long), the 745Le combined a refined luxury experience with the benefits of plug-in hybrid technology. This model aimed to provide a compelling alternative to traditional internal combustion engine (ICE) powered luxury sedans, offering reduced emissions and the ability to drive short distances on electric power alone. The “Le” designation signifies “Luxury Efficiency” within BMW’s naming convention.

Powertrain & Engine Architecture

At the heart of the 745Le lies BMW’s B58B30C 3.0-liter inline-six gasoline engine. This engine, a member of the modular B-series engine family, features direct injection, a twin-scroll turbocharger, and BMW’s VALVETRONIC variable valve timing system. It produces 286 horsepower and 450 Nm (331.9 lb-ft) of torque. Coupled with this is an electric motor, integrated between the engine and the 8-speed Steptronic automatic transmission, delivering an additional 113 horsepower and 265 Nm (195.45 lb-ft) of torque. The combined system output is a substantial 394 horsepower and 600 Nm (442.54 lb-ft) of torque. The 12 kWh lithium-ion battery pack is located under the rear seats, minimizing impact on trunk space. The battery supports DC fast charging, allowing for a relatively quick recharge time. The powertrain utilizes intelligent energy management to optimize the use of both the gasoline engine and the electric motor, seamlessly switching between them or combining their power for maximum performance.

Driving Characteristics

The 745Le offers a unique driving experience compared to its gasoline-only siblings. In electric mode, the car provides near-silent acceleration and a smooth, refined ride. The electric motor’s instant torque provides brisk acceleration for city driving. When the gasoline engine engages, the transition is generally seamless. The 8-speed Steptronic automatic transmission is well-tuned to the hybrid powertrain, providing smooth and responsive gear changes. While the 745Le is heavier than the 740i due to the battery pack, the combined power output ensures that performance remains competitive. The car’s weight distribution is also affected, potentially altering handling characteristics slightly compared to the lighter models. The air suspension contributes to a comfortable ride, absorbing bumps and imperfections in the road effectively.

Equipment & Trim Levels

The 745Le typically came well-equipped, reflecting its position as a premium model. Standard features included leather upholstery, power-adjustable seats with memory function, a large infotainment screen with iDrive controller, navigation system, premium sound system, and a comprehensive suite of driver-assistance systems such as lane departure warning, forward collision warning, and automatic emergency braking. Optional extras included features like massaging seats, rear-seat entertainment, a panoramic sunroof, and upgraded interior trim materials. The interior design was largely consistent with other G12 7 Series models, emphasizing luxury and sophistication.

Chassis & Braking

The 745Le utilizes a double-wishbone front suspension and an independent multi-link rear suspension, both incorporating BMW’s air suspension system. This system allows for adjustable ride height and damping, providing a comfortable and controlled ride. Ventilated disc brakes are fitted on all four wheels, providing ample stopping power. The car is equipped with ABS (Anti-lock Braking System), electronic stability control, and other advanced braking and safety features. The steering system is an electric power steering rack and pinion, offering precise and responsive steering feel.

Market Reception & Comparison

The 745Le was generally well-received by automotive critics, who praised its blend of luxury, performance, and efficiency. However, some reviewers noted that the battery pack added weight, slightly impacting handling agility. Compared to the 740i (with its 3.0-liter inline-six), the 745Le offered lower emissions and the ability to drive in electric mode, but at a higher price point. Compared to the 750i (with its V8 engine), the 745Le provided comparable performance in certain situations (particularly with the electric motor assisting) but lacked the V8’s overall power and sound. Fuel economy was a significant advantage for the 745Le, particularly for drivers who frequently commute in urban areas and can take advantage of electric charging infrastructure.

Legacy

The BMW 745Le xDrive represents an important milestone in BMW’s transition towards electrification. While the G12 7 Series has since been replaced by the G70 generation, the 745Le remains a desirable option in the used car market for buyers seeking a luxurious and efficient plug-in hybrid sedan. The B58 engine has proven to be a reliable and durable powerplant, and the hybrid system has generally demonstrated good long-term reliability. However, as with any complex hybrid system, potential buyers should be aware of the possibility of battery degradation and the associated costs of replacement or refurbishment. The 745Le paved the way for BMW’s current range of plug-in hybrid models and helped establish the brand as a leader in electrified luxury vehicles.
