Infiniti has unveiled its newest luxury SUV, the QX50, at the 2017 Los Angeles Auto Show on Tuesday night which features the first production-ready example of Infiniti’s new, variable compression ratio engine, better known as the VC-Turbo.
The groundbreaking petrol VC-Turbo is the first of its kind and claims to be more efficient than a diesel but without harmful emissions.
The company, which is the luxury subsidiary of Nissan Motors, says the VC-Turbo combines the thrust of a small turbocharged engine with the fuel-efficiency of a four cylinder diesel.
The Infiniti’s new 2.0-litre variable compression (VC) turbo means you can get petrol power but with diesel’s efficiency benefits. The lightweight VC-Turbo works by using a different compression rate, depending on how the owner is driving.
At lower speeds it’ll return diesel-like economy without throwing out harmful gases. At higher speeds you’ll get the performance of a V6 petrol engine.
The QX50’s engine will put out a promised 268 horsepower and 280 pound-feet of torque, and deliver a combined fuel economy of 27 miles per gallon on the front-wheel-drive models and 26 mpg on all-wheel-drive versions. Capable of 0 to 60 mph in 6.3 seconds, it will have a top speed of 143 mph.
The sleek SUV, which is a much more attractive design than the previous QX50, features luxury quilted seats, two screens in the cabin-one for sat nav and one for car controls vehicle.
It will also be outfitted with the ProPilot semi-automated driving-assist package found on other Infiniti and Nissan vehicles which means it can drive itself in a single lane on motorways and in stop-start traffic.
Mazda is working on a similar SkyActiv-X engine for its future motors but that’s not ready yet. The new QX50 will be priced at around £35,000 when it goes on sale next year.
