2019-2023 BMW X5 (G05) 45e (394 Hp) Plug-in hybrid xDrive Steptronic

The BMW X5 (G05) 45e xDrive, a plug-in hybrid variant of the third-generation X5, was produced from August 2019 to February 2023. Positioned as a premium offering within the G05 lineup, it combined a turbocharged inline-six gasoline engine with an electric motor, offering a balance of performance, efficiency, and all-wheel-drive capability. The 45e represented BMW’s push towards electrification in the luxury SUV segment, providing a compelling alternative to traditional gasoline-powered X5 models and competing with other plug-in hybrid SUVs like the Volvo XC90 Recharge and Mercedes-Benz GLE 350e.

Technical Specifications

INTRODUCTION

The BMW X5 45e xDrive, launched in 2019, represented a significant step in BMW’s electrification strategy. Built on the G05 X5 platform, it combined a 3.0-liter inline-six cylinder engine (B58B30C) with a powerful electric motor integrated into the eight-speed Steptronic automatic transmission. This configuration allowed for both all-electric driving for shorter distances and a combined output of 394 horsepower, providing strong performance and improved fuel efficiency. The 45e was aimed at buyers seeking a luxurious and capable SUV with the added benefit of reduced emissions and the potential for lower running costs.

Powertrain & Engine Architecture

At the heart of the X5 45e lies BMW’s B58B30C 3.0-liter inline-six engine. This engine utilizes direct fuel 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. The electric motor, delivering 113 horsepower and 265 Nm (195.45 lb-ft) of torque, is seamlessly integrated between the engine and the transmission. The combined system output of 394 hp and 600 Nm (442.54 lb-ft) is managed by a sophisticated power control system. The 24 kWh lithium-ion battery pack, located under the rear seats and floor, provides an all-electric range of 86-97 km (53.44 – 60.27 miles) based on the WLTP cycle. The eight-speed Steptronic automatic transmission is specifically tuned to work with the hybrid powertrain, offering smooth and efficient gear changes.

Driving Characteristics

The X5 45e delivers a unique driving experience. In electric mode, it offers near-silent operation and instant torque, making it ideal for city driving. Switching to hybrid mode allows the gasoline engine to kick in when more power is needed, such as during highway acceleration or overtaking. The combined power output provides brisk acceleration, with a 0-60 mph time of around 5.3 seconds. While slightly heavier than the gasoline-only X5 due to the battery pack, the weight distribution is well-managed, resulting in confident handling. The air suspension, standard on the 45e, contributes to a comfortable ride quality. Compared to the X5 xDrive40i (with a 3.0L inline-6 producing 335 hp), the 45e offers similar overall performance but with the added flexibility of electric-only driving. Compared to the X5 M50i (523 hp), the 45e sacrifices some outright performance but gains significant fuel efficiency.

Equipment & Trim Levels

The X5 45e came generously equipped as standard. Key features included BMW’s iDrive infotainment system with a 12.3-inch touchscreen, navigation, Apple CarPlay and Android Auto compatibility, leather upholstery, power-adjustable front seats with memory function, and a panoramic sunroof. Standard safety features included automatic emergency braking, lane departure warning, and blind-spot monitoring. Optional extras included premium sound systems (Harman Kardon or Bowers & Wilkins), massaging front seats, rear-seat entertainment systems, and various driver-assistance packages. The interior trim options were similar to those offered on other X5 models, allowing buyers to personalize the cabin to their preferences.

Chassis & Braking

The X5 45e utilizes a double-wishbone front suspension and an independent multi-link rear suspension, both equipped with air suspension as standard. This setup provides a comfortable ride and excellent handling characteristics. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. The regenerative braking system captures energy during deceleration, helping to recharge the battery and improve efficiency. The X5 45e also features BMW’s xDrive all-wheel-drive system, which intelligently distributes power between the front and rear wheels for optimal traction in all conditions.

Market Reception & Comparison

The X5 45e was generally well-received by automotive critics. It was praised for its blend of performance, efficiency, and luxury. Reviewers noted the seamless integration of the electric motor and gasoline engine, as well as the comfortable ride quality and spacious interior. Fuel economy was a major selling point, with the 45e offering significantly better MPG figures than its gasoline-only counterparts. Compared to competitors like the Volvo XC90 Recharge and Mercedes-Benz GLE 350e, the X5 45e was often cited as offering a more engaging driving experience and a more refined interior. However, some critics noted the higher price tag compared to other X5 models.

Legacy

The BMW X5 45e (G05) played a crucial role in establishing BMW as a leader in the luxury plug-in hybrid segment. The powertrain proved to be relatively reliable, with few widespread issues reported. On the used car market, the 45e holds its value well, reflecting its desirable combination of features and performance. As battery technology continues to improve, the X5 45e represents a transitional step towards a fully electric future for BMW’s SUV lineup, paving the way for models like the iX.
