What is the technical architecture of the 2025 QX50 and what does VC-Turbo technology mean?
The 2025 QX50 is built on the FF-L (Front-engine, Front-wheel drive based Luxury) platform shared with the Nissan Murano. Its architecture features a 2,800 mm wheelbase and 189 mm of ground clearance — adequate for Canadian road conditions. The VC-Turbo (Variable Compression Turbo) technology is the mechanical heart of the QX50: it is the world's first variable compression production engine, allowing its compression ratio to vary between 8:1 (maximum power) and 14:1 (maximum fuel economy) through a dual-balance shaft mechanism. In practice, this means a 268 hp engine that consumes like a naturally aspirated 4-cylinder during relaxed driving but delivers the performance of a large turbocharged 4-cylinder on demand. All Canadian 2025 QX50 variants include AWD, paired with a CVT (continuously variable transmission) — some drivers find this CVT less engaging than stepped automatic gearboxes offered by some competitors.
