Whether you're cruising on the highway or navigating city streets, the engine delivers a consistent and responsive performance.

Horsepower and Torque

When it comes to performance, the 2018 BMW X5 xDrive35i doesn't disappoint. The 3.0-liter inline-6 engine delivers a punchy 300 horsepower. This level of power ensures that the X5 can accelerate quickly and confidently, whether you're merging onto the highway or overtaking another vehicle. The horsepower figure is a testament to BMW's engineering expertise, showcasing their ability to extract significant power from a relatively compact engine. This high horsepower output translates to a thrilling driving experience, with plenty of power on tap whenever you need it.

In addition to horsepower, the engine also produces 300 lb-ft of torque. Torque is crucial for providing strong low-end acceleration and pulling power, making the X5 feel responsive and eager to move. The availability of torque across a wide RPM range means that the engine doesn't need to be revved high to deliver its best performance. This makes for a more relaxed and comfortable driving experience, especially in city traffic or when towing. The combination of high horsepower and torque ensures that the X5 is capable of handling a variety of driving situations with ease.

The engine's torque curve is designed to provide maximum pulling power at lower engine speeds, which is particularly useful for an SUV like the X5. This allows the vehicle to accelerate quickly from a standstill and maintain speed even when carrying heavy loads. The engine's responsiveness is further enhanced by the TwinPower Turbo technology, which minimizes turbo lag and ensures that power is delivered smoothly and consistently. Overall, the horsepower and torque figures of the 2018 BMW X5 xDrive35i demonstrate its ability to deliver a dynamic and engaging driving experience.

TwinPower Turbo Technology

One of the key features of the 2018 BMW X5 xDrive35i engine is its TwinPower Turbo technology. This advanced system uses a twin-scroll turbocharger to force more air into the engine, resulting in increased power and efficiency. Unlike traditional turbochargers, which can suffer from turbo lag (a delay in power delivery), the TwinPower Turbo system is designed to minimize this effect, providing a more immediate and responsive throttle response. This technology is a hallmark of modern BMW engines, and it plays a significant role in the X5's performance.

The twin-scroll design separates the exhaust flow from different cylinders, directing it to the turbine in a more efficient manner. This reduces exhaust backpressure and allows the turbocharger to spool up more quickly, resulting in improved throttle response and reduced turbo lag. The result is a more linear and predictable power delivery, making the X5 easier to control and more enjoyable to drive. The TwinPower Turbo system also contributes to the engine's fuel efficiency by optimizing combustion and reducing pumping losses.

Furthermore, the TwinPower Turbo technology is integrated with other engine management systems, such as direct fuel injection and variable valve timing, to further enhance performance and efficiency. Direct fuel injection delivers fuel directly into the combustion chamber, allowing for more precise control over the combustion process. Variable valve timing adjusts the timing and lift of the intake and exhaust valves, optimizing engine performance across a wide range of engine speeds. These technologies work together to ensure that the engine delivers maximum power and efficiency in all driving conditions. The TwinPower Turbo technology is a key differentiator for the 2018 BMW X5 xDrive35i, setting it apart from its competitors.

Transmission and Drivetrain

The 2018 BMW X5 xDrive35i is paired with an 8-speed automatic transmission, which is known for its smooth and precise gear changes. This transmission is designed to optimize both performance and fuel efficiency, providing quick acceleration and relaxed cruising. The 8-speed transmission offers a wide range of gear ratios, allowing the engine to operate at its most efficient RPM range in various driving conditions. Whether you're accelerating from a stop or cruising on the highway, the transmission seamlessly selects the appropriate gear for optimal performance.

The transmission also features multiple driving modes, including Sport, Comfort, and Eco Pro, which allow you to customize the driving experience to your preferences. In Sport mode, the transmission holds gears longer and shifts more aggressively, providing maximum performance. In Comfort mode, the transmission prioritizes smoothness and comfort, providing a relaxed and refined driving experience. In Eco Pro mode, the transmission optimizes fuel efficiency by shifting gears earlier and reducing throttle response.

In addition to the advanced transmission, the 2018 BMW X5 xDrive35i features BMW's xDrive all-wheel-drive system. This system provides enhanced traction and stability in all weather conditions, making the X5 a confident and capable performer. The xDrive system can distribute torque between the front and rear wheels as needed, ensuring optimal grip and control. This is particularly useful in slippery conditions, such as rain, snow, or ice. The combination of the 8-speed automatic transmission and the xDrive all-wheel-drive system ensures that the 2018 BMW X5 xDrive35i delivers a smooth, responsive, and confident driving experience.

Fuel Efficiency

For many drivers, fuel efficiency is a crucial consideration, and the 2018 BMW X5 xDrive35i strikes a good balance between performance and economy. The EPA estimates for the 2018 X5 xDrive35i are around 18 mpg in the city and 24 mpg on the highway. These figures are respectable for a luxury SUV of this size and performance capability. The fuel efficiency is a result of BMW's efforts to optimize the engine and transmission for maximum efficiency.

The TwinPower Turbo technology, direct fuel injection, and variable valve timing all contribute to the engine's efficiency. By optimizing combustion and reducing pumping losses, these technologies help to maximize fuel economy without sacrificing performance. The 8-speed automatic transmission also plays a role, allowing the engine to operate at its most efficient RPM range in various driving conditions. The transmission's wide range of gear ratios and multiple driving modes help to further optimize fuel efficiency.

In addition to these technologies, the 2018 BMW X5 xDrive35i also features several other fuel-saving measures, such as auto start-stop and regenerative braking. Auto start-stop automatically shuts off the engine when the vehicle is stopped, such as at a traffic light, and restarts it when the brake pedal is released. Regenerative braking captures energy that would otherwise be lost during braking and uses it to recharge the battery. These features help to further improve the fuel efficiency of the 2018 BMW X5 xDrive35i, making it a practical choice for drivers who want both performance and economy.
