After making a name for itself powering GTIs and Golf Rs, Volkswagen’s popular 2.0L turbo four-cylinder is about to get another starring role as a specially-tuned version promising more power and lower fuel consumption goes under the hood of the all-new 2018 Volkswagen Tiguan.
According to Automotive News, the latest member of VW’s EA888 engine family gets modified valve timing that reduces power output to 184 hp and 221 lb-ft of torque but comes with the promise of an eight percent better fuel economy rating compared to the 1.8L version of the motor used in the Golf, Jetta and Passat.
We already knew the EA888 was a flexible engine design: other members of the family include the 1.8L with its 170 hp/184 lb-ft, while the existing 2.0L cranks out 210 hp/258 lb-ft in the 2017 Volkswagen Golf GTI and 292 hp/280 lb-ft in the Golf R.
The new B-cycle 2.0L, as VW calls it, runs on a modified version of the Miller engine cycle. In a Miller engine, the valve timing system delays closing the intake valve until after the piston has begun its compression stroke. In the B-cycle, the intake valve closes sooner for more effective combustion, while variable valve timing adjusts that closing depending on engine load.
That helps boost fuel economy, while a longer stroke adds low-end torque that’s well suited to moving the extra weight of an SUV.
The 2018 Volkswagen Tiguan will arrive at Canadian dealerships in late summer.
