The all-new 2019 QX50 is powered by INFINITI’s new 2.0-liter VC-Turbo, the world’s first production-ready variable compression ratio engine – 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 optimize power and fuel efficiency. As a result, it combines the power of a 2.0-liter 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.
In operation, the 2019 QX50’s VC-Turbo engine offers any compression ratio between 8:1 (for high performance) and 14:1 (for high efficiency). The engine delivers 268 horsepower @ 5,600 rpm and 280 lb-ft of torque @ 1,600 – 4,800 rpm. The VC-Turbo’s specific power output is higher than many competing turbocharged gasoline engines, and comes close to the performance of some V6 gasoline engines. The unit’s single-scroll turbo ensures immediate accelerator responses, on demand.
Equipped with the VC-Turbo engine, the 2019 QX50 is competitively efficient, and delivers fuel economy of 27 mpg combined for front-wheel drive and 26 mpg combined for all-wheel drive models. In front-wheel drive specification, this offers a 35-percent improvement in fuel efficiency over the previous V6 engine, while the all-wheel drive model’s 26 mpg represents a 30-percent improvement.
Other highlights of the VC-Turbo include compact packaging and weight-saving technologies. The engine block and cylinder head are cast in lightweight aluminum alloy, while the transformative multi-link components are manufactured in high-carbon steel alloy. Compared to INFINITI’s 3.5-liter VQ V6 engine, the 2.0-liter VC-Turbo weighs about 40 pounds less and requires less space in the engine bay.
The QX50’s 2.0-liter 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 2019 QX50 is the only vehicle in its class to offer this kind of technology.
The new VC-Turbo engine is paired with INFINITI’s new XTRONIC continuously variable transmission – a shift-by-wire system that eliminates the need for traditional gears. The CVT in the all-new 2019 QX50 results in super-smooth gear shifts and seamless power delivery. The transmission adjusts immediately under hard acceleration as the engine transforms to a lower compression ratio. A higher gearing ratio for cruising speeds matches the higher compression ratio of the engine, enhancing fuel efficiency.
The shift-by-wire transmission also enhances the 2019 QX50’s powertrain packaging, with the fully electronic system replacing the mechanical transmission linkage, improving cabin space and allowing for a larger center armrest and center console.
The 2019 INFINITI QX50 is defined by distinctive proportions, which set the car apart from its competitors. Influenced by INFINITI’s “Powerful Elegance” design language – characterized by flowing sculptural lines and strong, muscular proportions – the all-new QX50 has an elevated, commanding crossover stance and strong character lines.
Within this design theme, the company’s signature design cues make the all-new QX50 instantly recognizable as a modern INFINITI. For example, the INFINITI-exclusive double-arch grille gives the face of the 2019 QX50 a unique and distinguished appearance. For use with the QX50, the double-arch grille is wider with no gaps between the grille and the hood. It is also positioned higher than on the previous-generation QX50, making the front of the car more distinctive, while ensuring the new model meets pedestrian crash test standards.
