Infiniti’s VC-Turbo variable compression engine was awarded 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 night, VC-Turbo was honoured for setting a new benchmark in terms of efficiency of next-generation combustion engines.
The experts of the automobile club acknowledged Infiniti for introducing the world’s first production-ready engine with variable compression. While in previous years, ARBÖ tended to award alternative propulsion systems, this year the organization recognized the efficiency potential of the VC-Turbo engine which represents the next step in optimizing fuel efficiency of the internal combustion 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. Thanks to 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 4-cylinder turbo and the fuel economy of a diesel powertrain without the emissions associated to a Diesel engine. The development objectives of the 2.0-liter four-cylinder engine with single-scroll turbocharger are: 268hp and 390Nm torque while offering at the same time 27% lower fuel consumption than similarly-powered V6 gasoline engines. The first Infiniti cars with the VC-Turbo engine will be on sale in 2018.
