In­finiti QX50’s VC-Turbo en­gine of­fers im­prove­ment New stan­dards

Muscat Daily - - CORPORATE NEWS -

In­finiti QX50 is pow­ered by In­finiti's new 2.0lt VC-Turbo, the world’s first pro­duc­tion-ready vari­able com­pres­sion ra­tio en­gine, jus­ti­fi­ably con­sid­ered one of the most ad­vanced in­ter­nal com­bus­tion en­gines ever cre­ated.

This unique vari­able com­pres­sion tech­nol­ogy rep­re­sents a break­through in com­bus­tion en­gine de­sign. The en­gine con­tin­u­ally trans­forms, ad­just­ing its com­pres­sion ra­tio to op­ti­mise power and fuel ef­fi­ciency. As a re­sult, it com­bines the power of a 2.0lt tur­bocharged gaso­line en­gine with the torque and ef­fi­ciency of an ad­vanced four-cylin­der diesel en­gine.

The VC-Turbo changes its com­pres­sion ra­tio seam­lessly with an ad­vanced multi-link sys­tem, con­tin­u­ously rais­ing or low­er­ing the pistons’ reach to trans­form com­pres­sion ra­tio – of­fer­ing both power and ef­fi­ciency on de­mand. A high com­pres­sion ra­tio gives greater ef­fi­ciency, but in cer­tain ap­pli­ca­tions poses the risk of pre­ma­ture com­bus­tion (knock­ing). A low com­pres­sion ra­tio al­lows for greater power and torque, and avoids knock­ing.

A se­nior spokesper­son at In­finiti Oman said, “The VC-Turbo en­gine of In­finiti QX50 is com­pet­i­tively ef­fi­cient, and de­liv­ers 268 hp (200 kW) and (380 Nm). Front-wheel drive mod­els of­fer a 35 per cent im­prove­ment in fuel ef­fi­ciency over the pre­vi­ous V6 gaso­line QX50; all-wheel drive mod­els of­fer a 30 per cent im­prove­ment.”

The en­gine is paired with a con­tin­u­ously vari­able trans­mis­sion (CVT), for seam­less power de­liv­ery. Its in­fi­nite num­ber of gears per­fectly matches the en­gine’s abil­ity to trans­form. The In­finiti’s QX50's 2.0lt VC-Turbo en­gine also em­ploys the world's first ac­tive en­gine mount vi­bra­tion damp­ing sys­tem, called an Ac­tive Torque Rod, to re­duce en­gine noise even fur­ther.

The In­finiti QX50 is built on an all-new plat­form, fea­tur­ing a front-en­gine, front-wheel drive­based lay­out. En­gi­neered with flex­i­bil­ity of ap­pli­ca­tion in mind, the new plat­form sets new stan­dards for re­fine­ment, rigid­ity and in­te­rior space in the com­pact premium SUV seg­ment.

The plat­form’s lay­out al­lows for higher lev­els of pack­ag­ing ef­fi­ciency than be­fore, re­sult­ing in the QX50’s ideal in­te­rior pro­por­tions for pas­sen­gers and cargo.

The QX50 rep­re­sents the first au­to­mo­tive use of SHF (Su­per High Forma­bil­ity) 980 MPa high-ten­sile steel, fur­ther strength­en­ing the all-new plat­form. The high-ten­sile ma­te­rial can be molded into un­prece­dented shapes, sav­ing weight and rep­re­sent­ing a tor­sional rigid­ity im­prove­ment of 23 per cent over the cur­rent QX50. This rigid­ity al­lows the car to re­sist flex and vi­bra­tions, as well as re­duce the level of noise trans­mit­ted to the cabin.

Pow­er­ful ele­gance de­sign

Re­main­ing true to the de­sign of the QX50 Con­cept and QX Sport In­spi­ra­tion, the QX50’s aero­dy­namic ex­te­rior rein­ter­prets In­finiti’s dis­tinc­tive Pow­er­ful Ele­gance de­sign lan­guage and sig­na­ture de­sign cues for the SUV seg­ment. It com­bines a con­fi­dent stance with in­tel­li­gent pack­ag­ing, while deep char­ac­ter lines high­light the in­flu­ence of hu­man artistry in the de­sign process.

At 1,678mm in height, the QX50 stands out on the road. Its el­e­vated driver po­si­tion max­imises vis­i­bil­ity, for a clear view whether driv­ing or park­ing. Aero­dy­namic ef­fi­ciency is key to the QX50’s de­sign – the drag co­ef­fi­cient is re­duced by 6 per cent com­pared to the pre­vi­ous QX50.
