Volkswagen has introduced a new petrol variant to the Golf range, which it claims offers diesel-like fuel economy but is cheaper to buy. The powertrain used in the Golf 1.5 TSI ACT BlueMotion will soon make its way to other Volkswagen models in the future as well.
The new variant is powered by a 1.5 litre turbocharged four-cylinder TSI Evo engine that makes 128 hp (130 PS) and 200 Nm of torque. The engine runs on the Miller combustion process, and utilises a turbocharger with variable turbine geometry (VTG). This combination of technologies, Volkswagen says, makes the engine 10% more efficient than comparable petrol engines.
Like the more powerful 148 hp (150 PS) 1.5 litre TSI Evo, the new powertrain features the Active Cylinder Management system that deactivates the two inner cylinders when the engine speed is between 1,400-4,000 rpm and at vehicle speeds of up to 130 km/h.
When combined with a seven-speed dual-clutch DSG gearbox, the powertrain is classified as a micro-hybrid system and comes with an ‘eco-coasting’ mode. Operating on a 12-volt electrical system, the engine management system switches off the engine completely and decouples it from the drivetrain by disengaging the clutch.
This happens when the driver lets the car coast, like predictively releasing the accelerator pedal for conditions ahead or when going down a slight slope. During this time, a lithium-ion battery provides the power necessary for the electrical equipment, such as the headlights, windscreen wipers, and infotainment system.
According to Volkswagen, the mode helps reduce fuel consumption by as much as 0.4 l/100 km. Overall, the new Golf variant returns a fuel economy of 4.8 l/100 km (combined), which can go down to as low as 4.0 l/100 km in extra-urban settings.

Hypermilers rejoice!
City driving, the engine shutdown would be good for coast to stop.
Highway cruising, the cylinder deactivation would be good.
Still no one can fix stop and go OR stop and crawl traffic yet though, without hybridising.
Does cylinder deactivation work during stop and crawl traffic ?
VW new 130PS 1.5TSI almost matching up to Suprima 1.6T
For a 1.5L DOHC tebo, 130PS is pitiful considering Civic tebo is 173PS. Even much older CFE tebo is 140PS.
This car is not intended to compete on performance but on economy. For performance there are other TSI models available with small capacity engines.
Shudnt economy be their bread and butter std engine? Why have 1.4L not-so-eco, 1.5L eco, 1.6L less-eco-but-cheaper, 1.8L somewhat-eco-diesel, 2.0L perf, 2.0 more perf, 3.2L OMG perf?
Way too much variant engines just for 1 car. Can standardise to 1.5L NA for economy, 1.5L tebo for more perf, 2.0L for hi perf.
Its targeting European market needs. Thats why they are number 1 in Europe. Because thats what the market wants.
CRV is 190ps
CRV is how many litres?
CRV 1.5Turbo 2WD 190ps. Best deal!
But FC wise VW wins
LOL… slower than a 1.5 civic turbo.
Lol more advanced than a civic turbo. Civic turbo is dinosaur tech to VW. Pls.
Lol 2 generation ago Jetta beat the shit out of your pathetic civic bro lol u want compare apa? Honda pride ? Hahahhaa joke
Agreed even the new Peugeot 1.2 L turbo world engine of the year still produces 130 HP and 250 NM OF TORQUE .
Much better than this VW 1.5 L engine in terms of efficiency with 300 c.c displacement less.
