2014 BMW ActiveHybrid 5: Hybrid Power Meets 5 Series Comfort
BMW’s 2014 ActiveHybrid 5 combines a turbocharged six-cylinder with electric drive, aiming to offer both performance and efficiency in the executive saloon class.
BMW’s ActiveHybrid 5, introduced for the 2014 model year, brought hybrid power to the heart of the 5 Series range. The car pairs the familiar 3.0-litre turbocharged straight-six from the 535i with a 40kW electric motor, producing a combined 340hp and 450Nm. This puts the hybrid’s performance figures close to the petrol-only 535i, but with an official combined fuel economy of 6.4 litres per 100km (44.1mpg) and CO2 emissions of 149g/km.
Hybrid system and driving modes
The ActiveHybrid 5’s drivetrain is configured with the electric motor mounted between the engine and the 8-speed automatic gearbox, replacing the torque converter. The lithium-ion battery is installed in the boot, which does reduce luggage capacity compared to other 5 Series models. The hybrid can drive on electric power alone at speeds up to 60km/h, though the range in this mode is limited. Under gentle acceleration and low speeds, the car will often stay in electric mode, but the petrol engine starts up quickly when more power is needed or the battery is depleted.
BMW offers three driving modes: Eco Pro, Comfort and Sport. Eco Pro prioritises electric running and efficiency, softening throttle response and disengaging the petrol engine for coasting where possible. Comfort mode is the default, balancing power and economy. Sport sharpens throttle and transmission response, combining the full output of both power sources and deactivating the start-stop system. In Sport, BMW’s own figures suggest fuel economy drops to around 11-12 l/100km (about 24mpg).
Performance and efficiency in practice
On paper, the ActiveHybrid 5’s 0-62mph time of 5.9 seconds matches the 535i closely. The electric motor’s boost is most noticeable at low speeds, helping the heavy saloon (at 1850kg, it is about 175kg heavier than the 535i) get off the line briskly. The hybrid system’s integration is generally smooth, though some drivers may notice a slight vibration when the petrol engine restarts after electric running.
Real-world fuel consumption varies. Highway cruising at steady speeds can deliver figures close to BMW’s claims, particularly with careful use of Eco Pro mode. In urban conditions, however, the petrol engine is required more often than in smaller hybrids, and consumption can rise to 10-12 l/100km (23-28mpg). The hybrid system’s ability to coast with the engine off and recover energy under braking helps, but the electric motor’s output is modest for a car of this size.
Handling, safety and equipment
Despite the extra weight, the ActiveHybrid 5 retains much of the 5 Series’ handling character. The steering remains precise and body control is good, though the additional mass is apparent in quicker corners. Optional Variable Damper Control is available for those seeking more adjustment. All 5 Series models, including the hybrid, earned five stars in Euro NCAP testing, and standard equipment includes curtain and side airbags, active headrests and post-collision braking.
The hybrid’s boot space is reduced due to the battery, which may matter for buyers needing maximum practicality. Otherwise, equipment levels are similar to the 535i, with navigation, climate control and standard driver assistance systems included.
Where the ActiveHybrid 5 fits in the BMW range
The ActiveHybrid 5 sits alongside the 535i in the 5 Series line-up, offering more power than the four-cylinder diesels but with the promise of improved efficiency over the six-cylinder petrol. For buyers prioritising low running costs, the 520d remains the most economical 5 Series, but the hybrid appeals to those seeking a blend of performance and lower emissions without moving to diesel.
