Diesel versions: Opel Astra ST hybrid with optional 1.2 Turbo petrol engines


The new Opel Astra Sports Tourer (station wagon) is available with three engines: 1.2 Turbo petrol engine, 1.5 diesel engine and Plug-In hybrid system. Power: from 110 to 180 hp. Most importantly, all drive systems provide very low fuel consumption, which I had the opportunity to test during the first test drives. Please see the report.

We have known for a long time that the new Opel Astra was created as a result of a collaboration between the German brand and the French PSA (owner of the Peugeot brand, and for several years also Opel). The range of drive units can already be attributed to the PSA group: it is the well-known 3-cylinder PureTech or the Plug-In hybrid based on the 1.6 liter unit. However, this is not bad news, because these are already well-known car systems, known eg for low fuel consumption. How do these engines cope with a car as big and bulky as the Opel Astra Sports Tourer?

It is not important, because the station wagon offers a wheelbase extended by almost 6 centimeters compared to the hatchback, which means that the length of the Opel Astra Sports Tourer exceeds 4.6 meters. This translates into a large trunk (516-597 liters) and plenty of space inside. I am 1.84 m tall and had more than 12 cm of free space in front of the roof, with the seat placed “according to art”. Back, when I was sitting “on my back” with my knees, I was a little relaxed, with about 10 cm of “slack” above my head. This is what we expect from a family owned car.

At the same time, the weight of the car was kept at a reasonable level. Astra Sports Tourer is heavier than the hatchback version by almost 50 kg and the total weight of the combustion versions is ~ 1400-1485 kg (including the driver). Along with less air resistance, this should ensure lower fuel consumption.

Opel Astra Sports Tourer with 1.5 diesel engine with 130 HP

The four-cylinder diesel engine with a capacity of 1.5 l and 130 HP is always connected to an automatic gearbox, 8-speed, also known from the PSA concern. Opel announces that the Astra Sports Tourer with such a unit will consume 4.7-4.6 l / 100 km in the combined cycle. Travel video:

It happened that during the test I encountered a huge traffic jam caused by a road collision, which in a sense simulated city traffic jams. Unfortunately, the room temperature was so high that the on-board computer did not allow to cut off the air conditioning, which meant that the engine did not turn off when the car was stopped. This increased the average fuel consumption by 0.5 liters per 100 km. Even without it, the result of 4.1 l / 100 km should be considered prestigious and should be described as an “economic center car” with such a powerful Astra.

During leisure driving, the diesel character of the engine is quite effectively hidden. The engine runs smoothly, without unwanted vibrations. The diesel mode can be heard, first of all, when forced to work at high speeds. The dynamics are quite adequate, and the automatic gearbox selects gears very well. I also didn’t see any shock.

Opel Astra Sports Tourer 1.2 Turbo 130 HP A8

The 1.2 Turbo is of course also the well-known PSA group’s 1.2-liter 3-cylinder engine with a capacity of 110 or 130 HP, which can be combined with a manual or automatic gearbox (only in the higher power version). Opel announces that the Astra Sports Tourer 1.2 Turbo 130 HP A8 requires an average consumption (WLTP) of 5.9-5.7 l / 100 km in the combined cycle. Travel video:

An hour later the blockage was gone, but the ambient temperature was higher. So Astra 1.2 Turbo was easy to achieve low fuel consumption. Finally, 4.6 l / 100 km is still below the manufacturer’s promises, although more by almost 1 l / 100 km compared to diesel (considering the same conditions). This just goes to show how efficient the 1.5 liter diesel unit is.

The Opel Astra Sports Tourer powered by the 1.2 Turbo engine drives well and the dynamics are satisfactory. However, compared to the diesel engine discussed earlier, the engine should run at higher revolutions more often. This leads to frequent shifting of the automatic transmission gears, and this … as if it worked worse in cooperation with the 1.2 Turbo compared to the 1.5 diesel. There were occasional gentle jerks, and the gearbox didn’t read the driver’s commands quickly enough. This is not the minimum, it was only better with diesel.

Opel Astra Sports Tourer 1.6 Turbo 180 HP Plug-In Hybrid

Of course, the plug hybrid test is more difficult and cannot be done completely during test drives. The route presented above (about 50 km) can be transported entirely by electricity. The same storage – a battery with a capacity of 12.4 kWh – in the Peugeot 308 allows you to get 55 kilometers in urban conditions. We can count on the same, possibly less symbolically in Astra’s case.

The leap in dynamics compared to the previously discussed 100% combustion units in the hybrid Astra is huge. The system is subject to software (a 225-hp variant is available in the group) and only the 1.6 l Turbo combustion engine offers 150 hp, and the electric motor 110 hp. In urban conditions, assuming that the car will be charged every day (only then it is reasonable to buy a Plug-In hybrid), you will be able to calculate an average fuel consumption of less than 1 l / 100 km + of course. used electricity.

However, higher efficiency and better dynamics come at a price. The hybrid Astra weighs about 300 kg more, and the luggage space is more than 80 liters smaller (mainly under the floor). However, it should be appreciated for the choice. If such a station wagon would be used often in urban conditions, and we live a little outside of it, for example, in a single-family house and we can connect the car to electricity in the garage, then the Plug-In hybrid makes sense!

How does the Opel Astra drive? Interior?

You can feel that the Astra’s chassis has been developed by Opel engineers. The suspension is pleasantly springy and allows fast cornering. At the same time, the operation is accurate, quite direct and not very assisted. The soundproofing of the interior is also at a good level.

You cannot have any major reservations about the interior. The quality of the materials used is generally very high: the elbows are soft and the leather upholstery is pleasant to the touch, especially on the steering wheel. Storage (hardware) is visible, but instead of the lower parts of the cabin, or possibly the shaft of the rear door.

The new system, transplanted from the PSA group, infotainment works quickly, although I have the opinion that the logic of operation was better in the Peugeot 308. However, I think it will be possible to get used to it, which I will check. during a long trial already here in Poland.

Opel Astra is available with two different front seats. Theoretically, in both cases we are dealing with an ergonomic shape, wide adjustment, and AGR certificate, but it is worth trying both models yourself, because it may turn out that one of them will suit your preferences better.

At the end

Opel Astra Sports Tourer is available with a wide range of power units, especially if we drive quietly. 130 HP in the case of the 1.2 Turbo or the 1.5 diesel engine will not let you go crazy. The Plug-In Hybrid with 180 HP will therefore take on the role of a sportier version. Let’s hope that a more powerful 225 HP version of this hybrid system will also be available.
