W he should be interested in the Astra CDTi don't forget this winter. Otherwise it could happen that incidental items like the anti-theft alarm system are ordered as special equipment instead of the Quickheat heater. The diesel can remain stolen in the icy cold anyway because of the slowly responding standard heating.

Is the turbodiesel even worth it? If he does

it is best to include the 260 euros extra for the rapid heating system on the basic price. Then, in the case of the Edition equipment, it is 23,250 euros and thus 2,675 euros above the 1.4-liter turbo gasoline engine with 140 hp, which is comparable in terms of performance - a rather generous difference that the diesel with its lower consumption with an annual mileage of 15,000 kilometers only comes back in after four and a half years. In addition, there are higher taxes and insurance costs. Is the turbodiesel even worth it?

There is a need for modernization of Opel engines

It is. But this is mainly due to the fact that the 1.4-liter gasoline engine is so unconvincing. The engine specially developed for the Astra combines moderate running smoothness with unwillingness to turn, poor pulling power and immodest consumption behavior (8.8 liters /100 km). However, the 1.7-liter turbodiesel in its 125 PS variant also proves that Opel has a need to modernize its engines. The machine goes back to an Isuzu development and, with its robust accent, already powered the Astra G from 1998. Opel is currently packing the engine under the hood of Corsa , Meriva , Zafira and that of the Astra. Ordinary manners brought the diesel to common rail injection years ago. Newer constructions may nail a little more gently, but the running culture is okay.

The running culture is okay, thePower delivery not

Not power delivery. In the city, the lethargy with which the Opel starts moving is annoying. The reason for this is an unfortunate combination of a long gear ratio, a turbo lag as large as Lake Constance and the slim figure of the Opel, which has a slight weight problem at 1,545 kilograms - many mid-range cars are lighter.

The high weight reduces the temper of the engine. There is nothing wrong with the acceleration values, here the Astra sprints at the level of the competition. On the other hand, when pulling through it - like all six-speed Astra - again the too long translation of the precise, but not particularly smoothly shiftable transmission. With its 280 Nm of torque, the diesel pulls out of the affair more quickly than the 1.4-liter turbo, but it often looks so tortured that it is better to shift down.

The consumption can hardly be pushed below the six-liter mark

And that goes to the consumption, which is even more cautious Driving style can hardly be pushed below the six-liter mark and averages seven liters /100 km. Ten years ago it would have been way ahead, today it is even undercut by a BMW 330d . So let's close the engine chapter by stating that the diesel is the better of two below-average engines.

The Astra has an excellent chassis, but also glaring weaknesses

In the Astra, it encounters a car with a number of distinct strengths - the excellent chassis, the precise one , feedback-intensive steering, the solid workmanship and the extensive standard equipment are just as much a part of it as the careful suspension comfort or the excellent optional ergonomic seats.

At the same time, Opel's compact model has some glaring weaknesses. These include the small car-like space in the rear and functional defects such as the operation with the button-overloaded center console, the small tailgate cutout and the poor clarity, which takes getting used to. All of this does not make it easy to warm up to the Astra CDTi - even with Quickheat.
