Nissan unveils variable-compression-ratio ICE for 2018 Infiniti production model

Nissan broke new ground for gasoline engines at the 2016 Paris Motor Show when it unveiled the first production-intent variable-compression-ratio gasoline engine. The VC-Turbo, a 2.0-L inline four cylinder designed in house, features a novel cranktrain and control system that enables the effective compression ratio to be varied between 8.0:1 and 14:1, depending on load.

Making its debut under the automaker's Infiniti brand, the VC-Turbo (VC-T) has been designed to replace the company's 3.5-L V6, with a target output of 268 hp (200 kW) and 288 lb·ft (390 N·m). Using two fuel-injection systems, Infiniti has set a target for fuel consumption reduction of 27% compared with the V6. The engine is being readied for series production in early 2018. The initial vehicle application is the new QX50 crossover.
