In recent months a large number of new SUV’s have broken cover. Not that you’d notice, as they are all fairly similar. Now though, Infiniti has announced its new QX50 model, and it does things a little differently.

This all-new very handsome looking SUV is built on an entirely new platform, and it boasts a trick turbocharged 2.0-litre four-cylinder engine dubbed ‘VC-Turbo’ that can vary its compression ratio from 8:1 to 14:1.

The reason for all the variableness, as I’m sure you are already aware is to maximise fuel-efficiency while remaining a potent powerplant. This VC-Turbo unit varies its compression to 8:1 when you need all of the horsepower and then switches to a lowly 14:1 when you just want to get somewhere while sipping fuel. This is done by adjusting the pistons’ reach and offers increased fuel efficiency by up to 35 percent over the old V6 unit found in the previous model.

All of this advanced technology gives the 2.0-litre motor 264bhp and 280lb-ft of torque which makes its way to all four wheels via a CVT gearbox. Despite the downside of the continual variable transmission (CVT), the new QX50 completes the 0-62mph dash in just 6.3 seconds while running onto 143mph at the top end.

Infiniti is claiming this new model's underpinnings gives it a 23 percent increase in torsional rigidity, thus reducing flex and vibrations, making it more refined in real-world driving. Also, that new sleek looking design gives the car a 6 percent improvement in the aero efficiency stakes.

The QX50 also features a raft of new driver assistance tech. This utilises Nissan’s own ProPilot Assist system. This can assist with self-steer, acceleration and braking on single-lane carriageways. While not close to full autonomy, it is a solid step in the effort to keep pace with the Tesla's of this world.

This new model will break cover at the LA Motor show when full technical details will be unveiled. It will go on sale in North America in 2018, with no UK release date yet confirmed.

Will this new super-advanced petrol engine be enough to pull drivers away from diesel or even hybrids? Let us know your thoughts in the comments.
