Almost all manufacturers are committed to electrification to reduce their average CO₂ emissions. Each year the supply of electric cars and plug-in hybrids is greater, giving the impression that only these are the cars that pollute the least. Bypassing the electric car (zero local emissions) and the plug-in hybrid (if proper use is made of it), there are internal combustion cars on the market that emit CO₂ emissions below 100 g / km. These are the 10 cars that consume less and pollute the Mercado.
All large manufacturers must comply with the average CO₂ emissions agreed by the European Union by 2021. That year, the average emissions of cars sold by each manufacturer or industrial group may not exceed 95 g / km of CO₂. If they fail to do so, the EU plans a fine of 95 euros for each extra g / km above 95 g / km and per car.
To achieve this, now that diesel has fallen out of favor (although in front of gasoline it is the one that emits the least CO₂), manufacturers bet on several technologies at the same time without attaching to any, except for Tesla who was born from the beginning as a manufacturer of electric cars.
Thus we find micro-hybrid or mild hybrid cars, electric hybrids, plug-in hybrids (known as PHEV, by Plug-In Hybrid Vehicle) and biofuel cars (which EU standards consider hybrids ) such as those that use gasoline and LPG (liquefied gas oil) or gasoline and CNG (compressed natural gas). Of course, there are also electric cars and the still incipient electric fuel cell.
However, the plug-in electric and hybrid car is not a valid option for any motorist, as they require a plugin the square where the car will spend the night. Going from public charging point to public charging point is not really practical and breaks the idea of using a PHEV electric or hybrid car.
Thus, in this summary of the cars that consume less and less pollute, we will leave out the electric ones, since they are all zero emissions at the local level, as well as plug-in hybrids and we will focus on combustion engine cars.
The ranking includes both gasoline and diesel models. To elaborate it, we have taken into account the measurements based on the WLTP click and not the NEDC (although many manufacturers continue to announce consumption and emissions depending on the NEDC cycle).
Of the 10 models in this ranking in descending order, none exceeds 100 g / km and four of them emit less than 90 g / km. On the other hand, it is not a surprise, the best values are electric hybrids. Another highlight is the low presence of diesel models.
On the one hand, it is a reflection of the market, that I do not demand so many diesel cars, and at the same time, it demonstrates the high costs for its manufacturer to adapt a small diesel to the current anti-pollution standards. It would have to impact on the final price those costs, making a small diesel not economically profitable. Finally, we find a single mild hybrid car, the Suzuki Ignis.
Suzuki Ignis 1.2 Mild Hybrid
The new Suzuki Ignis has a mini SUV design, but it is actually an eminently urban car. It measures 3.70 m long, is just 10 cm more than a Renault Twingo. Unlike the Gallic model, it offers a more complete range, it even has an all-wheel-drive version. The engine is a 4-cylinder petrol 1.2-liter turbo and a mild hybrid of 90 hp. This allows you to standardize an average consumption of 5.2 l / 100 km (4×2 version) and only 98 g / km of CO₂.
Dacia Sandero Blue dCi
Although most of the Dacia range shows relatively high consumption and emission values compared to Renault (which can be a problem for the French group ), the Romanian brand has a version that slips between the 10 cars that consume less and therefore emit CO₂. Of course, it is a diesel. This is the Dacia Sandero Blue dCi of 95 hp with a combined average consumption of 4.5 l / 100 km and CO₂ emissions of 98 g / km.
The new Toyota Corolla lacks a diesel engine in its range and compensates for it with two hybrid engines in its range. In this case, the Corolla that shows the best consumption and emissions figures is the access version with 1.8 engine of 122 hp, although in relative terms with respect to its power, the 2.0 liter of 180 hp is also sparse (but not so much as to enter the top 10).
Lexus UX 250h 4×2 Eco
The Lexus UX 250h is the most recent Toyota luxury seal proposal (you can read our test of this model here ). It equips the brand’s fourth-generation hybrid system, better known as Lexus Hybrid Drive. It has a 4-cylinder 2.0 liters for a combined total power of 184 hp. Of this Top 10, the Lexus UX is the most powerful, demonstrating that the power is not at odds with low approved emissions (94 g / km).
Renault Clio Blue dCi
While Renault finalizes the development of the hybrid version of the new Clio, Renault manages to be in the Top 10 of the least polluting with the diesel variants of the Clio. The 4-cylinder turbo 1.5-liter direct injection is available in two powers, 85 and 115 hp. Interestingly, it approves the same combined average consumption and the same emissions regardless of the power. By the way, it is the same engine that equips the Dacia Sandero Blue dCi that, however, does not get values as good as in the new Clio.
Lexus CT 200h Eco
The Lexus CT200h is one of the best selling models of the Japanese brand. The subject of a recent aesthetic and equipment update keeps its mechanics intact by combining a four-cylinder combustion engine (Atkinson cycle) and an electric one, for a total of 136 hp. And although it has been on the market since 2011, its hybrid system proves to be a success in terms of average consumption and emissions, since it ranks fifth with 4.8 l / 100 km on average and 94 g / km of CO₂.
The Suzuki Celerio is the pragmatic urban par excellence. It is small (3.60 m long), light (890 kg), spacious and with a small engine (3 petrol cylinders of 1.0-liter displacement for 68 hp). The equipment is basic and its design will attract attention, neither for good nor for bad. Of course, in return, it approves 4.8 l / 100km and less than 90 g / km of CO₂ without resorting to any kind of hybridization.
Kia Niro 1.6 HEV
The Kia Niro received his first restyling earlier this year. After less than three years in the market, Kia has sold 270,000 units worldwide (100,000 in Europe) and is the fifth best-selling model of the brand in the Old Continent. On a mechanical level, it equips a 4-cylinder 1.6 GDi gasoline combined with an electric motor for a total power of 141 hp. It also exists in plug-in and 100% electric hybrid version.
Toyota C-HR Hybrid
The Toyota C-HR Hybrid is a compact SUV in which the design prevails over practical considerations. But it is not an impediment to its success. On the contrary, it is one of the best selling models of the brand. On a mechanical level, the C-HR inherits directly from the previous Prius its gasoline-electric hybrid propeller group of 122 hp. Hence, it is not a surprise that it approved an average consumption of 4.7 l / 100 km and 86 g / km of CO₂ emissions.
Opel Corsa 1.5D
The new Opel Corsa is one of the most anticipated new batch utilities on the market, partly because it will have in its range an electric version, the Corsa-e . But it will also feature a classic range of internal combustion engines. Of that range, the 1.5-liter turbo diesel of 100 hp and 250 Nm is the most efficient version.
It incorporates diesel particulate filter, SCR catalyst with AdBlue injection and Nox trap. All this technological deployment pays off, as it approves an average consumption of 4 l / 100 km and 85 g / km of CO₂. Thus, it would be, for now, the car with an internal combustion engine that consumes less and pollutes the Spanish market.
