Volkswagen has updated its ubiquitous Golf model family ahead of 2017, introducing a number of changes, including revised TSI engines and a new 7-speed DSG.
Volkswagen states it has ‘enhanced’ its EA211 TSI engine family; which is set to debut in the 2017 Golf. The new turbocharged petrol direct-injection engines begins its roll-out with the ‘1.5 TSI Evo’; a 150 PS four-cylinder turbocharged petrol engine with Active Cylinder Management (ACT) and efficient common rail direct injection technology. The new TSI develops its maximum torque of 250 Nm at just 1,500 rpm, whilst returning NEDC fuel consumption of 4.9 l/100 km.
A BlueMotion version of the 1.5 TSI Evo with 130 PS is ‘also in preparation’ according to Volkswagen. Among the special characteristics of these high-tech engines are a new combustion cycle (derived from the Miller cycle) and a turbocharger with variable turbine geometry (VTG).
The engine develops its maximum torque of 200 Nm at just 1,400 rpm. As a world premiere, the 1.5 TSI Evo with 130 PS also offers an extended coasting function when the engine is deactivated – completely shutting down the TSI when the driver releases the accelerator. Such engine deactivation has only been seen in conjunction with hybrid vehicles up to now, as systems like the electromechanical power steering and the brake servo still need to be supplied with energy even when the Evo motor is switched off.
Beyond the TSI Evo engine, Volkswagen has also mildly revised the performance of its GTI models. An increase of 10PS sees power register now at 230 PS, while the power output of the new Golf GTI Performance has risen to 245 PS.
Other revisions to the range see the introduction of an all-new 7-speed DSG, which will gradually replace all of the 6-speed DSGs used in the Golf to date, helping to further cut CO2 emissions.
