VW Golf TSI BlueMotion

Mittwoch, 10. Mai. 2017

Our car tester Ines Petri tells us that Volkswagen has expanded the Golf family to include a new efficient engine. It's called BlueMotion, a designation that's already been used for diesel and natural gas engines. Now there's a 1-liter gasoline engine. So let's see what it can do.

What's under the hood? The three-cylinder 85 kilowatt motor ISN'T completely new. It's already used in the VW Polo and VW Caddy.

But in comparison to its predecessor, the 1-point-2 Liter TSI, it's around 10 kilos lighter. The primary purpose is efficiency. VW says the vehicle uses only 4.3 liters per 100 kilometers. That yields CO-2 emissions of 99 grams per kilometer.

Ines says out on the road, you notice the small engine. You have to step on the gas to get up to speed. But at 2000 RPM, the TSI Golf Blue Motion has a maximum torque of 200 Newton meters and a top speed of 204 kp-h. Plenty of power for passing.

Volkswagen’s Wolfgang Demmelbauer-Ebner says lots of things - rather than any one element - are special about this engine. For example, the cylinder head with an integrated exhaust manifold. The exhaust goes directly to the turbo-charger. It's cooled before it gets there.

The design allows the engine to manage heat better. That reduces friction inside the engine, and also gets it up to running temperature more quickly. That helps save fuel - especially on short trips.

Ines says the car comes with a standard six-gear transmission. But the car we tested was the 7 gear model, which costs 1875 euros more in Germany. The extra investment is well worth it, though. It gives drivers the option of driving the car in the normal energy-efficient or in the sports mode. The latter revs higher and makes the car faster.

The TSI BlueMotion may look like a regular Golf at first glance, but there are a lot of distinguishing technical details - such as the upper radiator grill, which is almost completely enclosed. Behind the lower air intake there are adjustable fins that optimize the aerodynamics and temperature.

The brake cooling channel is completely enclosed, which directs air around the vehicle. Also increasing efficiency are the super low friction tires and a chassis that has been lowered by 15 millimeters.

Ines says whether the car manages 4-point-3 liters in everyday conditions depends on how it's driven. But Volkwagen's new engine is a positive development for conventional engines. And the carmaker says there's more where that came from.
