2016-2019 BMW 7 Series (G11) 740e iPerformance (326 Hp) Plug-in Hybrid Steptronic

The BMW 740e iPerformance, produced from 2016 to 2019, represents BMW’s initial foray into plug-in hybrid technology within its flagship 7 Series (G11) sedan. Positioned as a technologically advanced and fuel-efficient alternative to the traditional gasoline-powered 7 Series models, the 740e aimed to appeal to buyers seeking luxury, performance, and reduced emissions. It was a key component of BMW’s strategy to offer electrified options across its model range, responding to increasingly stringent emissions regulations and growing consumer demand for sustainable mobility. The 740e iPerformance utilized the G11 chassis, sharing its core structure and dimensions with other 7 Series variants, but distinguished itself through its unique powertrain and associated technologies.

Technical Specifications

Powertrain & Engine Architecture

The 740e iPerformance’s powertrain centers around BMW’s B48 2.0-liter turbocharged inline-four cylinder gasoline engine, paired with an electric motor integrated into the eight-speed Steptronic automatic transmission. The gasoline engine produces 258 horsepower and 295 lb-ft of torque, while the electric motor contributes an additional 113 horsepower and 184 lb-ft of torque, resulting in a combined system output of 326 horsepower and 369 lb-ft of torque. The B48 engine features direct fuel injection, a twin-scroll turbocharger, and BMW’s VALVETRONIC variable valve timing system for optimized efficiency and responsiveness. The 9.2 kWh lithium-ion battery pack is located under the rear seats, minimizing impact on cabin space. The electric motor acts as both a power source and a generator during regenerative braking, capturing energy to recharge the battery. The transmission is specifically tuned to work seamlessly with both power sources, providing smooth transitions between electric, gasoline, and combined operation.

Driving Characteristics

The 740e iPerformance offers a unique driving experience, blending the refinement of a luxury sedan with the instant torque of an electric motor. In electric-only mode, the car provides silent and emissions-free driving for up to 29 miles, suitable for short commutes and urban driving. When the battery is depleted or additional power is needed, the gasoline engine seamlessly kicks in, providing ample acceleration. The combined output delivers a 0-60 mph time of around 5.1 seconds. The eight-speed Steptronic transmission offers smooth and precise gear changes, and the car’s suspension, featuring air springs, provides a comfortable ride. Compared to the 740i (gasoline-only model), the 740e feels slightly heavier due to the added weight of the battery pack, but the electric motor’s instant torque compensates for this, providing brisk acceleration. Compared to the 750i or 760i models with larger engines, the 740e offers a more balanced approach, prioritizing efficiency without sacrificing significant performance.

Equipment & Trim Levels

The 740e iPerformance came standard with a high level of equipment, reflecting its position as a flagship luxury vehicle. Standard features included leather upholstery, power-adjustable front seats with massage function, a premium sound system, a large infotainment screen with iDrive controller, navigation, and a suite of advanced driver-assistance systems such as lane departure warning, automatic emergency braking, and adaptive cruise control. Optional extras included upgraded leather options, rear-seat entertainment, a panoramic sunroof, and various customization options through BMW’s Individual program. The interior design was largely consistent with other 7 Series models, but featured unique trim elements and displays related to the plug-in hybrid system.

Chassis & Braking

The 740e iPerformance utilizes the same sophisticated chassis as other 7 Series models, featuring a double-wishbone front suspension and an independent multi-link rear suspension, both with air springs and adaptive dampers. This setup provides a comfortable ride and precise handling. The car is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. The electronic stability control system is specifically tuned to work with the hybrid powertrain, ensuring optimal control in various driving conditions. The steering is electrically assisted, offering precise and responsive feel.

Market Reception & Comparison

The BMW 740e iPerformance was generally well-received by critics, who praised its fuel efficiency, smooth driving experience, and luxurious interior. However, some reviewers noted that the electric-only range was relatively limited compared to some competitors. Compared to the 740i, the 740e offered significantly better fuel economy, particularly for drivers who frequently commute in urban areas. Compared to the higher-powered 750i and 760i models, the 740e provided a more balanced combination of performance and efficiency. The 740e’s plug-in hybrid system also qualified it for various government incentives and tax breaks, making it an attractive option for environmentally conscious buyers.

Legacy

The 740e iPerformance marked a significant step in BMW’s electrification strategy, paving the way for a wider range of plug-in hybrid and fully electric models. While the G11 7 Series has been replaced by the G70 generation, the 740e remains a desirable option in the used car market, particularly for buyers seeking a luxurious and fuel-efficient sedan. The B48 engine and eight-speed Steptronic transmission have proven to be reliable, and the hybrid system has generally held up well over time. However, as with any complex vehicle, regular maintenance and attention to the battery pack are essential to ensure long-term reliability.
