A versatile attitude and drivetrain to deal with any challenge

The QX30 is engineered to deliver a confidence-inspiring, dynamic driving experience, aided by intelligent all-wheel drive.

Development of the QX30 started at the brand’s technical centre in Japan, before moving to Europe for final validation and testing. In total, over 750 Infiniti engineers in Japan and Europe were involved in the development and testing of the Q30 and the QX30 in a wide variety of roads and environments.

Our holistic approach to engineering the QX30 has resulted in a car that delivers a precise, ‘in-command’ experience behind the wheel. The finely-tuned chassis and suspension, plus a number of assistive driver technologies, all work together to the benefit of the driver, providing a confident drive in all conditions and surroundings.”

Compared to Q30, the QX30’s chassis has been adapted with its own unique settings for a comfortable ride and confident handling in spite of its elevated ride height and ground clearance. Development teams responsible for QX30’s ride and handling worked hard to ensure the car’s dynamic characteristics met with buyers’ expectations of a vehicle that has been engineered to bridge the gap between compacts and crossovers. Its springs and rear anti-roll bar are stiffer, continuing the engineers’ efforts to ensure a flat ride. While the slightly firmer suspension helps to counteract the dynamic effects of a higher centre of gravity, the modifications to the chassis enable QX30 to remain comfortable at all speeds and over a variety of road surfaces.

The QX30 comes equipped with an intelligent all-wheel drive system. The drivetrain is able to send up to 50% of the engine’s power and torque to the rear axle to maintain traction on slippery surfaces and in inclement weather, enhancing a feeling of control and confidence when driving. For example, if a wheel slip is detected by sensors, braking is applied to the slipping wheel, while torque is sent to the gripping wheel for additional stability. Combined with the elevated ground clearance, the QX30’s drivetrain is engineered to deal with all conditions.

Another standard feature is the availability of a seven-speed dual-clutch transmission system. The dual-clutch intelligently pre-selects gears so the next shift is always ready to go, while manual mode lets the driver control gear changes when desired. Delivering seamless acceleration at any speed and in any gear, the application of torque is almost uninterrupted during gear changes, reducing lurching while in motion and between shifts.

Depending on market, there will be a choice between responsive diesel and gasoline engines for QX30 buyers – with specific details available closer to launch.
