There was a time when the vast majority of drivers opted for them, but in recent years they have lost a lot of prominence in the market, although there are still those who are reluctant to stop using them. diesel engines in favor of other more efficient mechanics such as electrified powertrains in traditional or plug-in hybrid configuration, as well as 100% electric models that are becoming increasingly important. However, some very important car manufacturers continue to bet on this type of mechanics and that translates into cars with fairly contained consumptionwhich we show you in this classification that we are about to meet.

The vast majority of them are utility vehicles, although there are also larger ones, in the form of compacts whose more generous dimensions do not prevent them from being among the most efficient on the market, as long as we are talking about those cars powered by diesel mechanics. Also, how could it be otherwise, a couple of SUVs appear, models that despite their greater bulk and height manage to homologate a fairly low fuel consumption for their characteristics. With all that said, it’s time to meet the 15 diesel cars that consume the least on the market.

15) Opel Mokka

Its four-cylinder 1.5-liter diesel engine produces 110 horsepower and a maximum torque of 250 Nm, with a six-speed manual gearbox that sends all the power to the front end. An efficient mechanism thanks to which the Opel Mokka homologates a combined cost of fuel 4.4 liters per 100 kilometers and its CO2 emissions stop at 116 gr/km.

14) Peugeot 2008

The other SUV in this classification copies the records of its German first cousin since both share the same mechanics, so that the Peugeot 2008 also homologous 4.4 liters per 100 kilometers. However, its top speed goes from 180 to 200 km/h and its acceleration from 0 to 100 km/h is completed in 9.5 seconds, which means that it is more than 1 s faster than the Mokka.

13) Hyundai i30

The Hyundai i30 also needs 4.4 liters to travel 100 kilometers thanks to a 1.6-liter turbodiesel engine, which produces 116 horsepower and a maximum torque of 280 Nm. This engine is associated with a six-speed manual transmission that sends all the energy to the front end, so that the Korean compact manages to reach 192 km/h.

12) Citroen C4

The Stellantis Group is one of the protagonists of this classification, so that many of those present here share motorization. In this case, the 1.5-liter, 110-horsepower engine is the main protagonist, a mechanism with which the Citroen C4 get homologated 4.3 liters per 100 kilometers.

11) Peugeot 308

The French compact again uses the aforementioned 1.5-liter four-cylinder mechanics, but this time it increases its performance as it offers 130 horsepower and a maximum torque of 300 Nm. These improved figures are linked to contained fuel consumption, since the Peugeot 308 settles for 4.3 liters to travel 100 kilometers.

10) Audi A3

The Audi A3 It uses a well-known propellant such as the 2.0 TDI, a four-cylinder engine that manages to develop 150 horsepower and a maximum torque of 360 Nm, being able to propel the compact up to 228 km/h. All this with a combined consumption of just 4.2 liters per 100 kilometers and CO2 emissions of 109 gr/km.

9) Fiat Type Sedan

The Italian compact sneaks into this list and does so with its four-door body, with a turbodiesel mechanics that barely has a displacement of 1.3 liters. It delivers 95 horsepower and a maximum torque of 200 Nm, associated with a five-speed manual gearbox with which the Fiat Tipo manages to standardize an average fuel cost of 4.2 l / 100 km.

8) Citroën C3

The French utility vehicle also manages to cover 100 kilometers with just 4.2 liters of fuel, thanks to a turbodiesel mechanism like the one mentioned in previous cases, only this time it is satisfied with 100 horsepower. The maximum torque is still 250 Nm and the gearbox is a five-speed manual. The maximum speed of this version of the Citroën C3 it is 188km/h.

7) Seat Leon

Another one that also needs 4.2 liters of fuel to complete a 100-kilometre journey is the Seat Leon, a compact that in its current generation uses the aforementioned 2.0 TDI block, in a slightly more decaffeinated configuration as it offers 115 horsepower and a maximum torque of 300 Nm. Its gearbox is a six-speed manual and the top speed stops at 200 km/h, while the maneuver from 0 to 100 km/h is completed in 10.2 seconds.

6) Skoda Octavia

As in the previous case, the Czech sedan uses the 2.0 TDI engine in its 115-horsepower configuration. The Skoda Octavia is the most spacious of all the vehicles present here and its approved average consumption, of 4.1 liters per 100 kilometers, also positions him as one of the most frugal on the list. Its CO2 emissions are 109 gr/km and the maximum speed is 211 km/h.

4) Opel Astra

Since Opel is part of the Stellantis Group, the German compact shares the drivetrain with other models of the French giant, such as the aforementioned Peugeot 308, so that under the hood there is a 1.5-liter mechanic that develops 130 horsepower. and a maximum torque of 300 Nm. Thanks to his presence, the Opel Astra can travel 100 kilometers requiring only 4.1 liters of diesel.

3) Ford Focus

It has just been updated and with the changes introduced by the oval brand, the Ford Focus It is positioned as one of the most interesting compact in the segment. Among its different engines is the 1.5 EcoBlue engine, either in a 95 or 120 horsepower configuration, with which it manages to standardize an average consumption of just 4 liters every 100 kilometers.

2) Opel Corsa

Like the last model mentioned, the Opel Corsa manages to travel 100 kilometers using only 4 liters of fuel, making it a very interesting alternative for all those looking for an efficient diesel utility vehicle. Its engine develops 100 horsepower and a maximum torque of 250 Nm, associated with a six-speed manual gearbox.

1) Peugeot 208

It is not the fastest in the classification, as its time to reach 100 km/h is 11.4 seconds and its maximum speed does not exceed 188 km/h, but the Peugeot 208 is one of the most frugal since it copies the consumption of the previous case: 4 liters per 100 kilometers. This is possible thanks to a motorization described in repeated cases, that is, the block of 1.5 liters and 100 hp. In addition, since it starts at 19,150 euros, it is cheaper than its cousin the Opel Corsa, so we have given it the first position in the ranking!
