After weeks of teaser photos, Infiniti has finally dropped the first official photo of the all-new QX50 ahead of its full debut at the upcoming Los Angeles Auto Show. Together with an all new body, Infiniti's new SUV brings with it the world's first production variable compression ratio gasoline engine.

Based on Infiniti's new front-wheel drive platform, power comes now comes from a turbocharged 2.0-liter four cylinder engine called VC-Turbo. It can adjust compression ratio from either 8:1 for peformance or 14:1 for fuel economy. Maximum power is rated at 272 PS and 380 Nm of torque which is then sent to the front wheels via a continuously variable transsmision (CVT).

Infiniti claims the QX50 in front-wheel drive guise can accelerate from 0-100 km/h in 6.3 seconds. All-wheel drive models are expected to be faster. Flat out, it can reach a top speed of 230 km/h. Compared to the outgoing V6 engine, the company says it can improve fuel economy by 27-percent.

Looking at the first official photo of the new QX50, we can see that Infiniti has remained faithful to original QX50 concept car's design. In fact one could say that the production body is just a toned down version of the concept. The new shape is also said to improve aerodynamic efficiency by 6-percent. Underneath its sleek design, Infiniti claims that the new structure has 23-percent improved torsional rigidity.

Like most new Infiniti models, the QX50 comes with the brand's ProPILOT semi-autonomous technology. The system assists with accelerator, brakes and steering to keep the car safely on the road.

For now, Infiniti has only revealed the front of their new SUV. More photos and other details are expected to be released once it has been fully revealed.
