Infiniti’s VC-Turbo variable compression engine (earlier post) was named by the Automobile, Motor and Bicycle Association of Austria (ARBÖ) with the Grand Austrian Automobile Award in the category “Environment.” During the awards ceremony that took place in Vienna last week, VC-Turbo was honored for setting a new benchmark in terms of efficiency of next-generation combustion engines.
While in previous years, ARBÖ has tended to award alternative propulsion systems, this year the organization recognized the potential of the VC-Turbo engine.
Infiniti engineers have worked for 20 years on the technology to make VC-Turbo production-ready. More than 100 prototypes were tested so as to deliver a truly innovative gas engine. Using a multi-link system, which is able to adapt the travel of the pistons’ stroke, the all-new engine can seamlessly offer any compression ratio between 8:1 and 14:1. Lower compression ratios secure greater power and torque, whereas a higher compression improves fuel efficiency.
The result is an engine delivering the power output of a V6 and the fuel economy of a diesel powertrain without the emissions associated with a diesel engine. The development objectives of the 2.0-liter four-cylinder engine with single-scroll turbocharger are: 268 hp and 390 N·m torque while offering at the same time 27% lower fuel consumption than similarly-powered V6 gasoline engines. The first Infiniti cars equipped with the VC-Turbo engine will be on sale in 2018.
