INFINITI’s variable compression ratio engine (VC-Turbo engine), the world’s first production variable compression ratio engine, was recognized by ALG with the Powertrain Innovation Award.
“We are honored to receive this recognition by ALG for the INFINITI VC-Turbo, which gives drivers an engine that is able to transform on demand, providing both performance and efficiency in a single package,” said Mike Colleran, vice president and managing director, INFINITI Americas. “The VC-Turbo engine debuted on the all-new 2019 QX50 last year, and since it arrived at retailers, the QX50 has consistently broken monthly sales records, and it has become one of the most popular models in INFINITI showrooms.”
The Powertrain Innovation Award from ALG recognizes powertrains that embody the driving experience, taking into account the elements of power, efficiency and handling dynamics.
“While alternative fuel and electrification are trendy topics, internal combustion is still the dominant engine choice worldwide. INFINITI engineers are proving there is still room for innovation with the introduction of the variable compression, VC-Turbo engine,” said Eric Lyman, senior vice president, ALG. “The ability to adjust compression ratio unlocks optimal power or efficiency depending on driver inputs. The result is an innovative engine with enhanced flexibility and applications.”
A breakthrough in combustion engine design, the 2.0-liter VC-Turbo engine adjusts its compression ratio to optimize power and efficiency. The VC-Turbo engine changes its compression ratio seamlessly with an advanced multi-link system, continuously raising or lowering the pistons’ reach, which provides the power and strength of a sprinter with the efficiency and endurance of a marathon runner.
In operation, the 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 hp at 5,600 rpm and 280 lb ft at 1,600 – 4,800 rpm. The VC-Turbo’s specific power output is higher than many competing turbocharged gasoline engines, and it comes close to the performance of some V6 gasoline engines. The unit’s single-scroll turbo ensures immediate accelerator responses on demand.
The VC-Turbo’s powerful-yet-compact footprint allows the entire cabin to move forward, revealing more interior space and making the 2019 QX50 one of few vehicles in its segment to offer sliding and reclining rear seating. The QX50 also boasts rear legroom of up to 38.7 inches and a trunk that can accommodate a stroller situated length-wise without letting down the back seats, with space for additional cargo.
Available at INFINITI retailers nationwide, the 2019 QX50 is the brand’s most advanced vehicle to date and embodies everything INFINITI stands for: Beautiful design, advanced technology and empowering performance features. Additionally, INFINITI’s available ProPILOT Assist technologies can offer support when needed and add to the enjoyment and confidence of the driver.
