DEATH of diesel? New 'breakthrough' Infiniti engine more efficient than diesel

["HaMsIK"]

nfiniti debuts the new QX50 SUV which has a brand-new petrol engine under the hood which could be a complete diesel killer. 

The internal compression engine allows the petrol engine to combust much more efficiently than a typical petrol. 

It will be able to allow efficiency that you would typically associate with a diesel in a petrol unit. 

Dubbed the ‘VC-Turbo’ 2.0-litre four-cylinder which has compression ratio between 8:1 to 14.1 for ultimate efficiency. 

When the driver wants more power the engine can compress at 8:1 and then drop down to 14:1 for a more economical drive. 

 

What it does is alter the reach of the piston to improve the overall fuel efficiency. 

Infiniti claims that it could improve overall efficiency by 35 per cent compared to the old QX50 V6. 

"Variable compression ratio technology represents a breakthrough in powertrain development," said Infiniti VP Randy Parker. 

"The QX50, powered by our VC-Turbo, is the first production vehicle ever to give drivers an engine that transforms on demand, setting a new benchmark for powertrain capability and refinement."

The technology is not all too dissimilar to the SKYACTIV-X engine Mazda is working on for its vehicles. 

“VC-Turbo technology is a step change for Infiniti,” said Roland Krueger, president of Infiniti. 

“It is a revolutionary next-step in optimising the efficiency of the internal combustion engine.”

It also develops 264bhp and 404Nm of torque and will cost around $30,000 when it goes on sale.
