Recently tested the 1.0 SIDI gasoline engine, which threatens much the hegemony of the CDTI as economic engines. This time we will see what is capable known 1.3 CDTI after being updated in this generation.
Best Car of the Year in Motor.es was renovated in early 2015, but we rather talk about a deep update, It is not an entirely new generation. We tested the three-cylinder 1.0 SIDI, and, truth be told, is a very interesting engine and doing better than more expensive alternatives. In addition, actually it spent little.
The 1.3 CDTI They are carried using the Corsa range for more than 10 years, but have been updated several times, both at and in the physical unit. It remains one of the smaller displacement diesel market, only 1,248 cubic centimeters, and the smallest four-cylinder.
E generation in, this engine produces or 70 CV with five speeds, or 95 hp with six-speed. Approval is exactly the same, 3.8 l / 100 km, or 3.7 l / 100 km if equipped tires with low rolling resistance. The unit tested fits a Continental 215/45 R17 wheels brand, Like the Corsa Turbo we have already tested. So it is equal, except for the fact that this is five-door.
The B13DTH engine is not exactly the same as its predecessors. Now it goes fine and refined than ever, and actual consumption has declined slightly
First kilometers usual route
After making sure that the tank was full to the mouth, I started doing my usual routes, which serve me quite accurately to compare different cars that I drive. It is a mixture of motorway journeys, roads and urban areas (minor), in which simulated the usual driving everyday.
According to the manufacturer, the 1.3 CDTI engine, which meets Euro 6, has a new generation of turbochargers, quieter. CV 95 have a maximum torque of 190 Nm between 1,500 and 3,500 RPM, 70 hp version gives the same pair, but up to 2,500 RPM. In other words, the 70 hp is slightly castrated, not homologated lower consumption.
The engine is very nice in the day, seems to have somewhat reduced the noise level, and has a raucous response. The same engine cars Fiat brand has been often lazy to despair below 1,500 RPM, but Opel engines calibrated differently, the best in my opinion.
Consumption measures the onboard computer is extremely precise, only 0.1 l / 100 km below the actual figure. It's no record, but actual spending is very content
In the first part of the test I ran 381.5 kilometers at an average of 64.7 km / h, consuming as computer 4.2 l / 100 km. Notice that almost half a tank mark, on the same route the petrol would have lost only two pictures. I even thought I had a mechanical problem or was broken indicator.
But no, I was wrong. I again fill diesel and entered 16.46 liters, which gives actual consumption of 4.3 l / 100 km, He is indicating virtually the same computer. In addition, there was still a range of 621 kilometers, which would have added 1,000 kilometers to stay completely dry deposit.
In the rest of the test, He had to make an act of faith, and not be afraid of how fast the fuel level down. I remember, has never happened to me driving an Opel Corsa from generating C, and believe me, it is very possible that has led at least 20 Corsas. I do not know if it's a particular problem with this unit, or diesel have a different indicator.
NOTE: I @nmjuancarlos clear that in this model the indicator works well, then it's no problem of unit testing
The biggest leap of generation D to E shows in the interior, looks like a car's quality, and has rejuvenated enough
Test long-haul four adults
It's time to do something harder, put more weight to the car and put jogging on the highway at 120-130 km / h to check your level of austerity. Small engines, like this we analyzed, usually have very bad about having additional efforts to overcome. According to the data sheet, with the driver (70 kg) five doors weighs 1,237 kilos, 38 kilos more than the three-door model.
I traveled with three adults to the coast and back, at a fairly steady pace. The sixth gear will not choke on the small diesel, Needless reduced to practically never fifth or a steep slope more than 5%. The sixth is not exactly short, usually it goes to 2,000 RPM, The first Corsa D CDTI 70 CV could circulate nearly 3,000 RPM under the same conditions.
And that decrease in speed is quite noticeable. You can not say that the engine go asphyxiated by an excessively long sixth. The gearbox is not the last generation (M1X), that it has received the three cylinders. Therefore, it is conducted virtually equal to any generation Corsa D, it is a little less pleasant and more mechanical feel.
The engine is round with six speeds, and are not excessively long. Furthermore, the engine moves into less noise
Reach my destination on the coast with a consumption of 4.4 l / 100 km depending on your computer, two tenths more, an average of 89.2 km / h. He is about to accumulate 500 kilometers in part, the fuel gauge was almost on a remaining quarter. Normally that happens with gasoline engines a little more greedy, like the 1.6 Turbo.
Knowing the low indicator faster than it should level I decided to risk and continue to Madrid without refueling again. After all, he showed a range of 489 kilometers, more than enough to return, even considering the negative effect that makes the difference in height, 700-odd meters of altitude.
Moreover, an increase of two tenths in consumption after loading more than 250 additional kilos, seems like a pittance. Moreover, in 2008 I tried a Corsa D 1.3 CDTI with 70 hp version less consumed at the time (3.5 l / 100 km approved) with five gears and various optimizations (ecoFLEX) and spent considerably more than the model tested . Of course, we have to talk about a marked improvement.
with virtually "quarter" in the tank, I decided to take my chances and go back to Madrid, without putting more diesel. Autonomy was theoretically surplus
