The Golf R model’s EA888 series engine has innovative engineering solutions such as water-cooled exhaust gas channels running through the cylinder head to the turbocharger to help efficiently reduce full-load fuel consumption. Thanks to its new fully-electronic coolant control system, the Golf R TSI engine has much more efficient thermal management with a reduced warm-up phase that reduces frictional losses and fuel consumption. In addition, the TSI engine has variable valve timing on the intake and exhaust sides, as well as two-stage exhaust-valve lift. This helps enable optimal control of the charge exchange process for better performance, fuel economy, and lower emissions.
