The new QX50 comes with the world’s first production variable compression ratio diesel engine.


Infiniti has taken the wraps off its new large SUV, the QX50, which comes with the world’s first production variable compression ratio engine.

Built on an all-new platform, the SUV’s turbocharged 2.0-litre, four-cylinder, diesel motor, which Infiniti calls VC-Turbo, can change its compression ratio from 8:1 (for better performance) to 14:1 (for improved fuel efficiency).

The engine, which develops 272hp and 380Nm of torque, is mated to a CVT gearbox that helps to deliver a claimed 35 percent increase in fuel efficiency compared to the previous QX50’s V6 motor. The all-wheel-drive variants see a 30 percent improvement in fuel economy.

The new underpinnings are claimed to provide best-in-class interior space compared to rivals such as the Audi Q5 and BMW X3. Luggage space has risen to 895 litres, expanding to 1,048 litres with the rear seats folded. Infiniti also claims that the new platform has enabled a 23 percent improvement in torsional rigidity, improving refinement. The sleeker design is also claimed to aid in this, with a 6 percent improvement in aerodynamic efficiency.

The QX50 has been equipped with a bevy of driver assistance technologies, based on parent company Nissan’s ProPilot Assist system. The tech helps with acceleration, braking and steering while on the highway. The Japanese brand claims that customer preference to remain a key element in driving means that they haven’t added a fully autonomous mode.

More details about the SUV will be revealed when the QX50 debuts at the upcoming LA motor show.
